Dear distinguished guests, participants, experts, engineers, scientists and students, I would
like to welcome you to the 19th Marine Industries Conference (MIC 2017) at beautiful Kish
Island. It is an exciting time for all of maritime sectors to gather again in another event to
exchange their ideas and information as well as showing their potentials and capabilities
to all participants and attendees. I am very proud that these annual conferences and exhi-
bitions, nowadays, have been recognized widely not only by the nation but also by other
international sectors- thanks to all individuals, public sectors and private firms that made
this happen.
Iranian Association of Naval Architects and Marine Engineers (IRANAME) as a significant
key player in Iranian Maritime Industry, is very proud and delighted to be your host again
here this year. Meanwhile, on behalf of IRANAME, I would like to thank all of you for your
participation and contribution to our various programs this year.
I know many of you have travelled from quite a distance and I’d like to acknowledge our
delegates from various international countries who have made this long trip to participate
in one of the largest, most extensive Maritime conference and exhibition we have ever had.
I’d like to give you an idea of what you can expect and we hope to achieve over the next few
days. Beside paper presentations which are scheduled in two parallel sessions on today and
tomorrow, there are interesting technical workshops, panels and relevant meetings in order
to fulfill your numerous needs and tastes. In addition, due to successful achievement of the
special offshore oil and gas technical panel last year, this technical panel has been organized
again this year with interesting agenda. I would like to thank Dr. Gh. Manouchehri, the
Deputy on Development and Engineering of National Iranian Oil Company, for accepting
the responsibility to organize and lead this important panel this year. For more details,

Today, indispensable effect of SEA in civilization, cultural and economical enrichment and merchant of nations is fully endorsed. SEA INDUSTRY is interpreted as an essential tool for a real and stable development of a country. The latter is very widespread, but includes though not limited to a major field of Marine applications, such as the maritime and off-shore structures, physical and engineering studies and challenges related to the marine en-vironment, such as Oil & Gas Upstream, renewable energies, shipping and naval industries.
The Nineteen’s Conference (2017) includes 6 invited plenary lectures on the Oil & Gas theme, 50 selected oral presentations along with 100 posters that are distributed among 10 thematic sessions that covered many of above said relevant topics of marine engineering. This proceeding contains 340 accepted papers from near to 450 manuscripts submitted to Conference.The papers were selected and graded via good contributions from recognized experts and university faculty members that collaborated in the organization of the thematic sessions of the Conference. This assures the acceptable quality and or applicability of the papers included in this book. Hereby, I appreciate efforts by all colleagues and relevant companies in the vast and exciting Sea industry that made this conference with its international exhibition, various work shops, Oral and poster presentations and mutual meetings to exchange and share new findings and move forward.

Abstract
Incubator as one of the socio-economic institutions work to help the
commercialization of their new products and technologies by supporting
the growth and development of emerging companies by improving the
opportunities of raising resources from resources. Socio-economic assets
of a growth center through the internal communication between the
members of the growth center include the technology companies deployed,
managers and staff of the Incubator and through external communication
with other stakeholders such as consultants, financial organizations,
universities and industries. But one of the most important topics that,
unfortunately, the Marine Science area has been less focused are the
centers of marine science development. By changing the paradigm of
development, from classical to new, sustainable development is becoming
the main pillar of development in any country. On the other hand, countries
that own light in the sea have defined the sustainable development of
seaworthy in their high-level documents. To this end, developed countries
had major educational and research investments in the sea basin, one of
the most important components of which was the development of marine
science development centers. To this end, the researcher provided a
qualitative study and documentary review of the position of the Marine
Science Development Centers in the sustainable development of
seaworthy; practical suggestions were made to the authorities for the
development of Marine Science Development Centers.

3 Instructor, Azad Islamic University of Kharg; [email protected]
Abstract
The role of a developed port in the economy and business relations of a country
is like as several industrial cities. Bushehr port has no enough space to develop
and provide extensive port services to the ports of the Persian Gulf region and the
world. For this reason, the traffic is being created in the port and the routes leading
to it and with the expansion of the port, the situation will become more
complicated. Lack of space for emptying, loading and storing loads and
containers is another serious problem in the lack of space around the port of
Bushehr. Another problem with Bushehr port and coastal ports with similar
conditions is the lack of proper access to the destinations and the use of traditional
means of transportation. In such circumstances, the value of using dry ports is
becoming increasingly apparent. Bushehr Port Despite the limited space and
volume of goods displaced and the need to develop and upgrade port services,
customers need a backyard such as a dry port that has both a proper road route to
the Bushehr port and a rail link. Based on the articles and research papers of others
and many interviews with Bushehr port officials, owners of ships, representatives
of ship owners, owners of factories, owners of goods, traders, etc., thirteen key
factors influencing the development of trade and transit of a port were identified.
In Bushehr province, there are three major cities of Borazjan, Choghadak and
Ahram near Bushehr port, which can be considered for feasibility, locating and
creating a dry port in order to resolve the problems of the port city of Bushehr.
To investigate this, it is assumed that facilities, financial resources, and
administrative cooperation exist for the construction of a dry port as necessary.
In this paper, analytical hierarchy process method is used for data analysis.

Provide an Energy Management Pattern at Nadim
Shipbuilding Corporation in the Persian Gulf
Jahandari 1, Tahmasebi 2 PhD student of business DBA Industrial Management Organization
Assistant Professor of Environmental Department, Payam Noor University, Bandar
Abstract
In recent years, for various reasons, including the gradual elimination of
government subsidies, more attention has been paid to the value of energy
in its various forms, and the need to calculate the amount of energy
consumption and consumption has emerged as an indispensable necessity.
Industries such as petrochemicals and refineries have been starting up
energy management for several years. But most organizations active in
other industries, such as Nadiam Shipbuilding Corporation, have been
neglecting strategic energy planning and energy efficiency due to low
energy costs in Iran. On the other hand, according to the law on targeting
subsidies and raising the price of energy carriers, today serious attention
has been paid to strategic planning and the presentation of an energy
management model in various organizations. Because otherwise, due to
increased energy costs, the cost of their products will increase and the
ability to compete in the market will be greatly reduced. Regarding the
products of Nadim Shipbuilding Corporation, which manufactures and
repairs ships and vessels, and given the presence of strong foreign
competitors, it can be concluded that the price advantage along with the
quality has a significant impact on the sales of the company's products.
Because the customers of this company are often very large governmental,
semi-public and private organizations and companies, the size of these
organizations, unlike the amount of contracts, which is sometimes very
heavy, is limited and low, so losing customers can be irreparable losses.
To the company that the development of the energy management model of
Navy Shipbuilding Corporation can prevent this damage. Therefore, in this
research, a model for energy management of Nadim Shipbuilding
Company has been developed to allow managers and planners to apply
appropriate strategies and management for the company's energy
consumption.

Abstract
Undoubtedly, one of the most influential factors in the economy of the
country is the maritime industry of the country. In this regard, due to the
wide blue border of our country, we can create conditions that, with the
development of this industry, we can enjoy the potential of the sea in
various fields, including the resistance economy. Considering the strategic
role of shipping and ports of the country in the national economy as well
as the international nature and competitiveness of this industry, the need
to implement the foundations of resilience economy is more than ever
before. It is only in the shadow of the application of the foundations of a
resilient economy that ports and the country's maritime transportation
system can play a decisive role in the transit of goods and transit in the
Persian Gulf and the Persian Gulf. Sea basins, including ports, can play an
important role in resilient economies through non-oil exports, tourism, and
maritime transport. The purpose of this research is to investigate the role
of sea and port components in resistance economy.

Abstract
Free spanning as one of the of the effective parameters on the pipeline
fatigue life capacity happens due to the uneven seabed, scoring, and
artificial supports. Under special conditions, free spanning can lead to
pipeline fatigue. If the shedding frequency close to pipeline natural
frequency, pipeline failure may occur. In this paper, the most popular limit
state functions on pipeline spanning are discussed and reviewed. Then,
using First-Order Reliability Method and Monte –Carlo Sampling, health
and integrity of a pipeline located in the Persian Gulf considering different
limit state functions corresponding different span length to pipeline
diameter and different soil classes are assessed. Furthermore, in order to
determine the effect of each parameter on failure probability, several
sensitivity assessments are carried out. It is concluded that First-Order
Reliability Method can be applied in case of large span length to pipeline
diameter and hard soil. Also, no failure didn’t happen for soft soils.

Abstract
The spigots widely use in different industries and based on different
circumstances have different duty such as rectifiers – chokers surrenders –
regulators and mixers the flow in the pipe. one of the kinds of the spigots
is spherical type. In this paper one spherical spigot is numerically
simulated and has been used mixture model to calculate cavitation too.
Result showed that three main hydrodynamic vortices explain the current
in the spherical spigot. The third vortex has a lot of effects in the span of
the pressure drop’s area in front of the spherical spigot and the cavitation
occurs in high angles of the spigot. Therefore, we can use this kind of
spigot when we don’t have high cavitation. Also it is noted that low
pressure differences is determinative factor to prevent cavitations'
phenomenon.

Abstract
This paper presents a steady-state energy, exergy, environmental and
economic (4E) analysis for hybrid compression-absorption refrigeration
system on a merchant ship. Exhaust gases of auxiliary engines are used to
vaporize high pressure water as a heat source for the generator of the
absorption section. The results show that exhaust gases of auxiliary engine
unlike main engine is an appropriate and permanent heat source for the
system. based on tropical conditions, fuel consumption and total
irreversibility rate of the proposed system are 91.8% and 26% less than
conventional system (vapor compression refrigeration system)
respectively. Because of the anxiety about environmental issues, an
environmental analysis has been conducted that the results show that the
application of hybrid compression-absorption refrigeration system causes
68664 $ annual saving versus vapor compression refrigeration system due
to reduction in CO2 emission penalty(cost). Also, economic analysis has
been done where the results show 3 years and 3 months for payback time
of proposed system.

Detection and classification of various types of ships that pass through a
waterway is one of the issues that have been considered by many
researchers nowadays. Detection and classification of the ships can be
considered from many aspects such as security, control, and military,
which in each of the cases mentioned, special measures are taken with
regard to the type of the ship. In this paper, we are trying to provide a
method for detecting and classifying five different classes of ships. In this
research, first, the key points related to the images of different classes are
extracted using the speeded up robust features extraction algorithm. Then
using the bag-Of-Words model and applying the K-Means function, the
key points obtained are clustered. Then, we obtain the histogram of the
centers of the clusters as the visual words for the existing images in
different categories, and finally, detect the type of the ship by categorizing
it using the support vector machine. Experimental results show that with
the proposed method, ships are classified with high precision in these five
groups.

Abstract
The purpose of this study was to assess the dangers of pipeline operations
and the separation of tanker vessels from the quay in Kharg Island. In this
research, the risk factors in the process of pipeline operation and the
separation of tankers from the quay in Kharg Island have been evaluated
and analyzed using the method of analyzing the state of failure and its
effects using the theory (FMEA). Estimation of risk factors by collecting
data from a working group of five experienced and experienced experts in
the island of Kharg, which included two tanker captains, two guides and a
tugboat captain. The results of the FMEA method show that, according to
the FMEA group, the potential risk of falling into the sea when towing, the
fall of the people to the sea, the time of joining the ship, the fall of the
people to the sea when they landed, and the technical violation or
inefficiency of the tow Operations accounted for the highest RPN rating
and were unbeatable in the group. Hence, measures to reduce the level of
risk have been defined, among which the most important is the supervision
of the commander of the ship on the equipment and work of the personnel
involved in the operation of the transfer of guidance. Also, the guy's
knowledge of the standards of the equipment guidance and checking it
before using them has a lot of effect in reducing the level of risk.
Investigating and using the experience of guides can change and improve
the forwarding system in the future.

Abstract
Fuel costs are one of the most important sectors affecting shipping costs
and the shipping industry. Fuel consumption in large vessels of about 1,000 to
5,000 liters per hour. And the cost of energy consumed during the life of the
vessel will be at $ million. On this basis, making even small changes to the body
system, thrust and propulsion that reduces fuel consumption, it will have
significant effects on reducing shipping costs. The global energy crisis and on the
other hand, the establishment of international maritime conventions to reduce the
environmental pollution caused by fuel consumption of the ships have led to
research into reducing fuel consumption and pollution caused by it. In this
research, the effect of changes in geometric characteristics (pitch ratio, cord ratio
and thickness ratio) of the propeller has been taken into account on the fuel
consumption of the ship and the resulting pollution. For this purpose, has been
tried to rely on the theory of elemental elements, the role of the geometric
variations of the propeller on the fuel consumption of the system and the index
of pollution in operational conditions are analyzed. Investigations have shown
that the changes in propeller efficiency are inversely proportional to changes in
the cord and pitch ratio and a change in the thickness ratio will have a negligible
effect on the propulsion efficiency. On the other hand, the process of changing
fuel consumption and pollution index are directly proportional with changes in
the pitch and cord ratio. Considering the operational profile of the ship and the
price of the fuel used, it was determined. Forty percent reduction in the pitch and
cord ratios, as compared to the original design, would result in cost savings of
425.77 and 179.978 milion toman per year, respectively. In addition, the
operational efficiency index of ship energy efficiency is reduced by 20.67% and
8.74%, respectively.

Ship to ship (STS) transfer operation is the transfer of cargo between
seagoing ships while stationary or underway. The ship of Recipients of the
goods is called daughter vessel and ship of Provider of goods that to be
lightened is called Mother Vessel. The reasons for turning to these methods
include the lightening of a ship before entering the harbor or to recover
floating force of ships that have been deducted floating force due to
accidental incidents, Fueling operations, reserving time in a very compact
schedule, Commercial reasons such as changes in owner of the cargo while
the ship is at sea. Since ship-to-ship operations are very complex and the
occurrence of an incident for the two ships during the operation may cause
significant or irreparable damage or loss of human life on both sides.
Identifying the potential hazards of ship to ship operation is essential and
it is necessary that after identifying them, appropriate strategy or strategies
are presented to prevent the risk. Therefore, in this thesis, the potential
risks of ship to ship operation at the Kharg oil terminal have been identified
and appropriate strategies to prevent the risk have been presented. In this
research, after the study of others' research, standards and instructions
related to ship to ship operation and interviews with experts in the field of
ship to ship operation, the potential hazards of ship to ship operation were
identified and on the basis of a questionnaire that answered by 50 experts
of ship to ship operation, data were analyzed by using a paired analysis

Abstract
In the present study, a central air conditioning system is designed to
provide the comfort for the crews. Since the accurately calculation of the
thermal loads and the inflow of air for each section is a most important
factor in choosing an air conditioner system. At the first, the thermal load
created by the walls, floor and ceiling, windows, people, lighting are
accurately calculated by the code that is written in MATLAB with couple
by Excel software, and then the air inflow was revealed to any room.
Second, at the first step, an air conditioner and a condensing chiller were
introduced as a central air conditioning system.Then at the second step, an
air conditioner and an absorption chiller were introduced as a central air-
conditioning system and when floating engine is on, a heat exchanger was
suggested that by using the water used for cooling engine, enough hot
water for the absorption chiller is supplied. A boiler is also foreseen for
shutdown periods of the floating engine. The results show that with regard
to the higher efficiency coefficient of compression chillers than absorption
chillers, in the absence of cooling engine water for heating water in the
adsorption chiller, compression chillers are more useful. But in the current
situation and with regard to the availability of having and using engine
cooling water, absorbing chillers is the best choice. The results also show
that optimum use of cooled water heat can save fuel consumption in diesel
generator, so after a while, the higher cost of recuperating chillers is
compensated by reducing fuel consumption.

Abstract
Nowadays, according to the high benefits of Surface-Piercing propeller
compared to immersed propellers, they are used in Planning hulls. Since
the modeling of these groups of Propellers is limited by theoretical
methods, experimental studies are carried out on them. Experimental
studies of Surface-Piercing Propellers are carried out in devices known as
Towing Tank and Free surface water tunnels. In this study, a free surface
water tunnel constructed in Babol Noshirvani University of Technology
was used to test the model of a Surface-Piercing Propeller. Since the
dimensionless Advanced Coeficient parameter in the surface-Piercing
Propeller test is great importance, speed calibration was performed in the
test section. Then the uncertainty analysis was done to verify the accuracy
of the data. In order to calculate the hydrodynamic coefficients of the thrust
and torque, a dynamometer system has been used. This system has been
constructed and Calibration of dynamometer was done for measurement.
By providing the test conditions of the propeller model, the test was carried
out at an shaft angle of 0 ° and for different immersion ratios. In this study,
a 5-blade propeller with a diameter of 135 mm and a 26 mm hub diameter
was used. The results indicate that, with increasing imersion ratio, the
hydrodynamic coefficients also increase. The critical Advanced ratio for
this propeller is in the range of 0.65 ≤ J ≤ 0.75 .

Abstract
The structural and operational model governing the bulk and container
shipping markets and its prospects is investigated. The breadth of the bulk
market, along with the efforts of the players in this market to reduce costs
and maximize the use of ships, has been examined. It seems that the
models that these markets are operating in will change in coming years.
One aspect of this change would be more interaction with customers.
Majority of these changes has been to reduce costs and increase the
survival and competitiveness of companies. The place of competition
between shipping companies would be more likely the kind of relationship
between companies and their customers, which can affect a large part of
the supply chain of these markets. Issues such as future financial
conditions and major environmental regulations affecting the shipping
industry, its consequences for the maritime shipping market and the
various solutions proposed by the International Shipping Organization to
comply with these regulations have been addressed.

Abstract
Safety of human resource is one of the most vital factors in safe operation
of ports. Promoting safety of logistics workers can be accomplished by
effective training.This research has been carried out in order to improve
the level of safety of port security logistics personnel through the
effectiveness of the provided trainings in a qualitative and case study
Chabahar port. At first, the logistics officers of the affected port were
interviewed and the incidence of accidents was investigated. Then,
different levels of organization were interviewed from high to lower
grades. In order to find the effective factors in reducing the effectiveness
of training after the relevant research, the researchers derived six main
codes. These six floors include the use of unskilled port logistics workers,
Chabahar Special Conditions, cultural and ethnic differences, lack of
effective monitoring of the performance of private contractors in ports,
lack of obligation and enforcement of laws and there is also a lack of port
security equipment.

Abstract
Recognizing the potential effects on marine ecosystems from introductions
of harmful non-native animals and plants from ballast waters, the IMO has
taken action by developing guidelines which aim to minimize the risks of
environmental damage, whilst maintaining ship safety. This paper will
provide an overview of the current international provisions, mainly those
established by the IMO on the matter, as well as describe how the subject
is currently treated in Iran, including through a review of national
legislations, institutions, and observations on the limitations of the current
approaches and the conduct of a Port State Control Inspection, to verify
compliance with the requirements of the International Convention for the
Control and Management of Ships’ Ballast Water and Sediments, 2004
(BWM Convention),which is not intended to limit the rights the port State
has in verifying compliance with the BWM Convention. Regarding the
role of ports in the national ballast water management program, this study
will also review the possibility of establishing standardized procedures for
environmental licensing of ports and terminals in Iran, including the
necessary criteria for ballast water management.

Study of the Effectiveness of Trainings for Port
Logistics Workers in Improving the Safety Level of
Ports
Emad Gholam Reza 1, Alimohammadi Negar 2 1 PhD, University of Tasmania, Maritime Education and Training;
2 MSc, Maritime Transportation; [email protected]
Abstract
The success of a port depends on its performance in an environment with
an acceptable level of risk. This can be achieved when their trained
competent workforces perform their duties in a safe workplace.
Workforce-related mishaps not only create severe problems for the port
and its productivity but also their impact may extend beyond the port
boundaries. Improving the safety level for port logistics workers is directly
related to the effectiveness of their training. The main objective of this
research is to study the effectiveness of the training offered to port logistics
workers and its impact on enhancing their safety. This paper is based on
the findings of a qualitative case study research performed in the Chabahar
port. The research shows the inefficiency of port logistics workers’
competency development and training system. The underlying factors can
be summarized in three major areas, namely; funding, safety awareness,
and operational issues. To address these factors a number of
recommendations have been suggested with the aim to resolve the
impediments that hinder the increasing effectiveness of training.

Abstract
Although Iran has a long shipping history but no impressive development
can be seen in the legal issues. There has been many factors causing such
lagging behind, including low knowledge of all those who involved in
marine insurance, legal issues and maritime law and wrong assumption
when dealing with such rules and legal issues. The other factor which can
be noticed is the shortcoming in the marine contracts. In this article we
tried to investigate the few important non liability of the carriers due to
exceptions in the rules in this regard. We also noted on the privileged rules
in case of existence of more than one rule, hopping to be used as a guide
line for those who need to be more conversant in these fields.
We opine that the best way of solving the difficulties in maritime legal
issues is that all who are involving with marine industries, update
themselves and study the regulation and rules including local and
internationals. Contracts of carriage, contracts of insurance, policies, all
required to be carefully written to avoid any ambiguities.

Administration of the Bushehr province; Email:[email protected]
Abstract
Despite repeated efforts on building safety vessels and using advanced
equipment such as navigation equipment and safety equipment, marine
accidents still occur, resulting in personal injury and property damages and
pollution of the marine environment. According to the studies, a large
percentage of the accidents are rooted in human errors, and some are due
to structural defects. However, the second category also converts to
accidents because of human error, but paying more attention to structural
defects can prevent similar accidents in the future. Therefore, the purpose
of this report is to investigate the accidents caused by adverse stability
(sustainability) of vessels in Bushehr province, which should be specially
considered according to the importance of the investigation and the
number of similar accidents.

Bio-Fouling Organisms And Their Effects On
Marine Ecosystems Mohammad Gorgij Jaski, Kiomars Roohani
Abstract
All surfaces in the marine environment are exposed to a variety of
biological, physical and chemical factors that result in the formation of a
complex layer of attached microorganisms and macroorganisms referred
to as biofouling. This organisms are known as a settlement or an
attachment of a community of usually visible plants and animals on
manmade structures (Immersed structures such as hulls, navigational
buoys, underwater equipment, seawater piping systems, industrial or
municipal intakes, beach well structures, oil rigs and cages) and farmed
species (mussels, scallops, oysters etc) exposed to seawater environment.
Biofouling includes diverse organisms such as barnacles, bivalves,
bryozoans, polychaetes, ascidians, hydroids, sponges and algae. Because
of their attachment to manmade structures barnacles are viewed as major
biofoulers. Biofouling promotes corrosion of materials. The principal
objective of biofouling control technique is to prevent the growth of
unwanted aquatic organisms on manmade structures. The direct economic
costs of biofouling control to the aquaculture industry are substantial, with
estimates of 5–10% of production costs attributed to biofouling. Most
control strategies are designed to treat the larval and juvenile stages of
fouling organisms, although some of these strategies are effective against
adults as well. Traditionally, the control of biofouling has involved costly
and labor intensive mechanical processes coupled with the use of toxic
antifouling coatings. Coating marine structures with paints containing tri-
butyl tin (TBT) or copper are the most common method to deter fouling
organisms from settling and attaching. In this review we will discuss the
fouling of marine structures and marine organisms, the problems
associated with biofouling in manmade structures and aquaculture, and a
range of control or antifouling technologies currently available in the
world.
Keywords: Biofouling, barnacles, marine structures, control strategies.

Today, to avoid in large-scale losses as well as life and substantial financial
disadvantages in defense systems, strengthening immunity of this systems
against human casualties and system, have become one of the hottest topics
discussed by scholars and experts of central defense. In this paper,
different potential causes for the reduction in personnel safety in coastal
missile launch system, using statistical data collected from similar systems
experts and system administration have been identified. Also according to
the system lifetime, including maintenance, transportation, loading and
launch, the fault tree is made to identify the causes of damage to personnel.
In conventional fault tree analysis, the likelihood of main event was based
exact probability of basic events. However often in defense systems is
difficult obtain of accurate and adequate information for basic events.
Thus, in this paper, a hybrid approach from the fuzzy sets and fault tree
analysis is used for evaluation probabilistic safety of personnel in this
system. Also using the resulting probability of this method and derived
severity of hazards from expert’s opinions, risk of hazards is calculated.
The calculated results hazards can be defined as a perfect platform to make
decisions and prioritize corrective actions for these risks.

Abstract
The purpose of this study is to investigate the effects of Biofouling on the
structures and construction coastal of Khorramshahr port. Sampling was
carried out in January 2015 and June 2016 from the docks in the tidal zone
of the port with the assistance of a quadrature 15×15 cm diameter. After
identifying and investigating the Fouling species, 11 species belonging to
10 families, were calculated, which consisted of 79% Maxillopoda, 5%
Bivalvia, 3% Green algae, 4% Malacostraca, 3% Bryozoa, 1%,
Polychaeta. The dominant species was Amphibalanus amphitrite with
density of 4261 individuals per unit plane. The most damaged docks of the
port are by other environmental factors. And the effects of Biofouling are
very superficial and caused by the jaw excrementof the Isopoda and or the
Green algae from produced secretions and Bivalvia that make the digestion
of concrete structures. Due to the unevenness of the Barnacles' coating on
concrete surfaces, it not only prevents the insulation of these organisms,
but also exacerbates corrosion and erosion at the naked surfaces of
Barnacle.

Harmful Algae Blooms Pollution and their effects
on marine Ecosystems

M. Mortazavi
Abstract
Studies have shown that the most phytoplankton blooms usually provide
positive impacts on marine ecosystems. However, blooming of certain
species of phytoplankton may also have negative impacts which this type
of blooms is called Harmful Algal Bloom (HAB). Evidence suggests that
over the past few decades the frequency and duration of Harmful Algal
Blooms (HABs) have been increasing both nationally and worldwide.
Therefore, HABs can cause severe problems on marine organisms and
public health often via toxin transfer through the food web, tourism, or
mechanical damage on seawater desalination facilities. Several factors
such as environment, climate change and human activities contribute to
this phenomenon that can leave harmful impacts on animals and
ecosystem. This paper provides an overview of HABs occurring along the
Persian Gulf and Oman Sea coastline with special emphasis on the
Cochlodinium polycrikoides. A large and sudden outbreak occurred from
August 2008 to May 2009 and lasted for more than eight months. It caused
massive fish kills and limiting traditional fishery operations, damaging
coral reefs, impacting coastal tourism, and forcing the closure of
desalination plants and ultimately resulting in economic losses. Moreover,
this paper aims to provide brief results of research projects on C.
polykrikoides in the Persian Gulf of Iran.

Abstract
The green sea turtle (Chelonia mydas) has been a species of global concern
for decades. In this study, heavy metals ((Hg,Cd, Pb, Cu and Zn) were
measured three egg fraction from green sea turtle (C. mydas) nesting on
the northern coast of oman sea. There are no significant differences
between concentrations of heavy metals in eggs laid at different times.
Low concentrations of heavy metals support the information about green
sea turtles’ food resources being from the low levels of the food chain.
Further research is required concerning the effects of heavy metals on
green sea turtles, especially on the extent that they influence fetal
development of these turtles. Moreover, studies must be conducted on
hatch rates because environmental contaminants are maternally
transmitted.

Investigation on Mercury pollution in seawater,
Plankton and Pony fish (Leiognathus bindus) of
Mahshahr Creeks Alireza Safahieh, Eshagh Hashemi, Mohammadali Salari Aliabadi,
Kamal Ghanemi
Abstract Located in the North West Persian Gulf, Khor Musa is an important water body
due to presence of various industries such as petrochemicals, fisheries, Ports,
marine shipping and oil installations. There is not enough information on the
trend of mercury variations in different food chains in this ecosystem. This study
aimed to evaluate the concentration of mercury in seawater and different parts of
marine food chain in Khor Musa (Mahshahr creeks), including plankton and
orange fins pony fish Leiognathus bindus. Sampling was carried out at five
stations including Petroshimi, Majidieh, Ghazaleh, Aboukhozair and
Doraghestan creeks in October and November 2012. After digestion of the
samples in the laboratory, the concentration of mercury was measured using cold
vapor method. The results showed that by moving from lower trophic level to the
higher level, concentration of mercury increases in living organisms. The lowest
concentration of mercury was measured in seawater followed by planktons (90
μg / kg). The concentration of mercury in fish (which is plankton feeder and is
considered as consumer) was 1090 μg / kg which was increased by about 10 folds
compared to plankton. The concentration of mercury in seawater, plankton and
fish samples from Mahshahr creeks was higher than what is reported for some
locations and available standards which is indication of mercury pollution in the
area. Significant correlation was found between the concentration of mercury in
seawater and its level in plankton (P<0.05). Similar positive and significant
correlation was found between the concentration of mercury in plankton and fish
(P<0.05), which could be noticed as an indication of mercury biomagnification.
Mercury concentration was higher in seawater of petroshimi and jafari creeks
which are closer to petrochemical installations and provides evidence for
contribution of the mentioned industry in mercury pollution. By moving far away
from petrochemical complex, the concentration of mercury in seawater and other
components reduced dramatically. The minimum amount of mercury was found
in seawater and components of Doraghestan and Aboukhozair creeks. Generally,
the trend of mercury concentration was increasing toward the higher trophic level.
More precise monitoring and more stringent management practices are needed to
prevent the release of mercury into the seawater of this region and continuous
monitoring of mercury in the region is recommended.

Abstract
Today, one of the main issues addressed by the Marine Environment
Protection Committee (MEPC) in the International Maritime Organization
(IMO) is the matter of the annex 6 of the Marine Pollution Convention
(MARPOL) and the IMO strategy to reduce Greenhouse gas emissions in
international shipping. Differences in the countries level of technology for
the production of low sulfur fuel and manufacturing of engines to obtain
an efficient combustion have led to not being fully compatible with this
annex of convention. In this paper, we consider methods to assess the
overall readiness of measures and outline areas where further action is
needed to increase the respective measures uptake with taking into account
three key factors of technological readiness, implementation time and
system readiness. By comparing proposed alternative resources, three
factors which are ease of implementation, cost of implementation and
impact of measures for the member states are explained. One of the
important measures for replacing of the energy resource is massive
production of non-fossil energy sources, structure modification of
propulsion systems and modification of the maritime transportation
infrastructure to supply fuel and carry out bunkering operations.

Abstract
With increasing environmental concerns from activists in this field, we
have witnessed the more activites from International Maritime
Organization (IMO) in reviewing the existing situation and introducing
new environmental regulations in the form of conventions and other laws.
These conventions are always one of the concerns of ship owners. Because
it is necessary for owners to have enough knowledge about conditions of
regulations before they are implemented in order to maintain the
seaworthiness and continuation of their fleet business activity, and to
anticipate and define sufficient measures to comply with its requirements
before the deadlines set. These measures usually involve restrictions and
costs for shipping companies, and the volume of changes and
improvements needed along with the market's unfavorable conditions
often tend to encourage ship owners to even scrap their ships. In this paper,
we have tried to consider the environmental regulations affecting the
shipping industry, its consequences for shipping market and the various
solutions proposed by the International Shipping community to comply
with these regulations.

Abstract
The aim of this study was to evaluate and manage the most effective
strategic components in the implementation and implementation of the
HSE culture in the industry. Always the risks and incidents of possible
accidents due to the lack of knowledge and culture of protecting the safety
and the environment have created irreparable consequences. So in this
regard, creating a HSE culture-building process in the industry and
creating awareness can significantly reduce the probable damage. This
research has been carried out to minimize injury damage in four
operational-research phases. In the first phase, due to the familiarity of the
research team with a process of industries as a case study, the rolling
industry affiliated to the marine industry was selected. In the second phase,
using the Delphi technique, an expert survey was conducted to identify the
strategic components for effective implementation of the HSE culture. In
the third phase, due to the optimal management and prioritization of
identified components for running the flow, they were placed in the AHP
hierarchical analytical model. Finally, improvements to the HSE culture of
excellence have been proposed and proposed in the industry.

Abstract
Gulf islands have always had dusty days during the year. In this
study dusting systems are studied. This study is based on meteorological
data of the synoptic stations of the Persian Gulf (wind, pressure, horizontal
visibility, temperature and relative humidity) also The study is based on
maps of the Earth's surface and the intermediate levels of the atmosphere.
Results showed The two systems play a significant role in creating dust in
the Persian Gulf. One of which is influenced by low pressure in the warm
seasons of the year and one of its type is High pressure in cold seasons.
The first type is the more frequent expansion of its activities from the west
and south of the Persian Gulf and it is affected by low thermal pressure
And it's more abundant in the western islands. The second type has a lower
abundance and durability compared to the first type and It is caused by
Siberian high pressure system. This system is specially for fall and winter,
And more is seen on the eastern islands.

Abstract
Today, the creation of a safe working environment and the proper use of
tools and equipment, and in particular safety equipment, are essential
throughout the world, and mariners, boats and passengers are not excluded
from these rules. Accidents in various transport sectors are inevitable that
they annually bring a lot of losses to the players in this industry. The
maritime industry is no exception to this phenomenon, and as a rule,
incidents are occurring for a variety of reasons. Therefore, it is necessary
to minimize the occurrence of incidents and minimize the consequences
and costs of identifying the effective factors in the occurrence of accidents,
control and eliminate or minimize them, and play important role in the
development of the transportation industry. After investigating and
identifying the factors affecting the occurrence of marine accidents on
vessels engaged in international and unlimited travel, using the paired
comparison analysis method, the priority of marine events were assessed
in terms of the extent of the impact and continued on how to reduce the
incidence of marine events and institutionalize the culture of Marine
safety, considering the important role of human error in occurring marine
accidents and increasing the level of safety of ship personnel.

Abstract
Meeting and gathering sea creatures on immovable surfaces immersed in
seawater under the name of biofouling can inflict irreparable damage to
large, engineered marine structures. These annoying sticky creatures are
one of the most important problems facing the world's maritime industry.
Today, various biological and chemical methods are used to prevent the
accumulation and accumulation of sticky and annoying organisms. One of
these commonly used anti-fouling coatings is more of a type of paint.
Colored coatings are used in ships in a wide range of applications such as
corrosion of metals, ease of protection, better appearance, as a coating to
prevent the presence of unwanted intruders. The function of these colors
is as anti-folding, with release or biomass in the sea. The toxicity of these
biochemical agents is known as anti-folding properties of the paint and
therefore has limited its use. In this review, new methods have been
considered, including the use of nanoparticle-based coatings.

[email protected] Abstract
The arrival of non-indigenous and invasive marine species has increased
dramatically in most areas of the water over the last century, and the
evidence suggests that this trend continues. These species are considered
as one of the four major threats to the oceans as a result of various
contaminations. Invasive species, in addition to transferring water through
equilibrium, are also transported to the body of the ship through
biofouling. The most important law on water balances and invasive species
is the Convention on the Control and Management of Water Balances and
Waste Sediments, which, in accordance with Article 6 of the Convention,
all members should "promote and facilitate scientific and technical
research on water-balance management, and the effects of water
management Monitor the balance in the waters under their jurisdiction. "
Therefore, the introduction of standard and scientific methods in the study
of these species can be an introduction to the implementation of this
Convention, which has been in force since September this year. The
purpose of this research is to introduce a scientific method for studying
invasive species in Biofolding communities.

The importance of wind waves in the marine environment, especially in
coastal areas, has led researchers in recent years to identify the
characteristics of these waves using various methods. Among the several
methods, numerical modeling is one of the most widely used methods for
achieving the mentioned goal. That way in this study SWAN spectral-
numerical model was used in wind wave modeling in the north of the
Persian Gulf, and in particular near the Farur Island using CCMP wind
field data. The results of three different methods of modeling based on the
interaction between air and water, and the whitecapping were compared
with the measured data. It was determined that WAM4-AB method has the
best performance compared to the other two methods. At the end of the
study, the sensitivity analysis performed on the WAM4-AB whitecapping
coefficients as the best method of the first stage of modeling and the
selection of values 4e-5 and 2.25e-3 for the whitecapping coefficient and
the threshold saturation level. It reduces the error by 8.5% of the spectral
peak period and decreases by 10% of the underestimation of significant
wave height.

[email protected] Abstract
Today the basis of human exploration in the sea and in the oceans will be
submarine robots in different ways. With the prosperity of the maritime
industry and the presence of these small craft, the Marine Corps set a new
stage and The design and manufacture of these objects is increasing day
by day, so that all the photographs and filming, marine searches such as
the identification of the ships destroyed and rescued by the diver and etc
will be handled by these small but powerful bodies. These robots are
present in all parts of the sea and the oceans and even in the tough areas of
the sea where no human being has ever been exposed, so wait for these
ships to arrive in all the deep waters of the world. In this paper, the effect
of the interaction of two underwater robots with similar bodies intersection
with the underwater flow was investigated and evaluated for optimal
distance in depths. Then the forces imposed on both bodies were calculated
and evaluated and good matching was achieved. In the end with the
analysis of collisional currents and velocity components around the bodies,
there were significant results in the behavior of two or more intelligent
submarine robots at different distances.

Abstract
Considering the importance of regional sea level evaluation, sea level
anomaly, net surface heat flux and wind stress data have been obtained on
northwest Indian Ocean. According to trend analysis, sea level change in
the northwest Indian Ocean is increasing with the rate of 0.5 – 4 mm/year.
Although, the maximum trend of sea level changes is calculated about 8
mm/year around western coasts of India that show the coastal waves
effects on the sea level trend. Spatial leading modes and time-series for
each of three mentioned datasets are computed by using the EOF analysis.
Then, the frequencies of leading modes of EOF are recognized by the
spectral analysis. Correlation analyses between sea level anomaly and net
surface heat flux leading modes are support the thermal expansion effects
on sea level but, this effects in second leading mode (37.7%) is more
significant than first leading mode (48.9%). Also, correlation analyses
results between sea level and wind stress anomaly reveal that the nature of
wind blowing and stress on the northwest Indian Ocean cause the warm
water pumping downward and increasing in the depth of tropical
thermocline, so wind stress mostly leads positive sea level anomaly on this
area.

Abstract
It is very important to assess how the components affecting the regional
sea level anomalies. In general, sea level fluctuations can be decomposed
to three components including Barotropic, Steric and Inverted Barometric.
In the present study, the effect of inverted barometer was investigated on
the Arabian sea. For this purpose, datasets of sea level anomaly, sea
surface temperature, salinity and pressure were obtained and the annual
cycles of inverted barometer anomaly were calculated. According to the
interpretations, variability of inverted barometer effects on the sea level
fluctuations are seasonal with two cycles per year which the variabilities
are reversed from high latitudes to low latitudes. Inverted barometer
effects on the sea level fluctuations are significant along the whole months
except December. The range of positive values of non-barometer
component is more than negative values, across the region, that is revealed
the non-barometer component more contributes to positive sea level
anomalies. Distribution of non-barometer effects over Arabian sea show
that the non-barometer effects are originating and entering from south area
of Arabian sea due to interaction with Indian Ocean, and attenuating during
the year with deviation to the north and west.

Classification of Bottom Roughness
Akbar Rashidi, Hasan Rabeie, Vahid Cheshmsiyahi
Abstract
In this study the modified version of non-linear 3D finite elements
hydrostatic QUODDY-4 model is used to investigate the sensitivity of
dynamics and energetics of tidal constituents M2, S2, K1 and O1 in
Chabahar bay to variability of bottom friction coefficient. This version
differs from the original version in that it has a module introduced to
calculate the bottom friction coefficient in the bottom boundary layer,
based on Kagan's resistance laws for different types of underlying surfaces
from hydrodynamic perspective. Model is run in two modes for each four
tidal constituents, considering constant and variable friction coefficient.
According to the results, the use of constant and variable resistance
coefficient does not make significant changes on dynamics and energetics
in the Chabahar bay. Comparison between the results of the simulations
and available observational data shows that the model has good accuracy
in reproduction of diurnal and semidiurnal tidal dynamics in the studied
basin.

Abstract
The prediction of the added resistance and attainable ship speed under
actual weather conditions is essential to evaluate the true ship
performance. In this study, added resistance of the KCS ship under random
waves in different sea states is estimated with numerical simulation. At
first, the numerical simulation of the ship model was carried out in calm
water, and then calculated added resistance and motions of ship under
regular waves in the design speed (Fr = 0.26). Results show that the
numerical results have a reasonable agreement with the available CFD and
EFD results. Finally, using the RAO and wave spectrum in each sea states,
the added resistance in the real sea is estimated under irregular waves.
Numerical methods based on URANS (Unsteady Reynolds-Averaged
Navier-Stokes) equations and STAR CCM+ software has been used. The
flow around the hull is incompressible turbulence flow (K-Epsilon
turbulence model) and to simulate the free surface flow around the body
VOF method is used. Also to improve and develop solution in region with
complex geometry (bow and stern) mesh cell size is adopted smaller than
other areas. The results of this study indicated the required margin of ship
performance, which should be considered in the early stages of design,
especially the choice of propulsion system.

Study of Numerical Model salinity prediction in
northern part of the Persian Gulf
Rokni, S.A. M.Sc of Meteorology, Space Physic Department, Institute of Geophysic, University of
Tehran, Iran Abstract
The northern part of the Persian Gulf due to climatic, military, politic
commercial and economic sensitive conditions, is important for its
countries bordering, For this reason, the study of water salinity pattern at
this basin has a high importance. wind stress is one of the most important
factors on water salinity pattern. The investigation of salinity pattern in
Persian Gulf especially in north areas based on the obtained results
illustrate a fixed trend. The minimum of salinity is in spring and the
maximum in fall. Thanks to Persian Gulf’s shallow nature salinity stems
two factors ones wind stress and second heat and humidity fluxes.
Minimum salinity in Iranian coasts especially in spring occurs due to
water penetration from oman sea into Persian Gulf. The investigation of
salinity trends in Persian Gulf especially in north areas based on the
obtained results suggests that salinity changes in this area follow a fixed
trend whose average during the whole year is 𝟑𝟗. 𝟏𝟐𝑔𝑟
𝑙𝑖𝑡⁄ that decreases
to𝟑𝟔. 𝟔𝟖𝑔𝑟
𝑙𝑖𝑡⁄ minimum in summer and rises to 𝟑𝟗. 𝟑𝟒𝑔𝑟
𝑙𝑖𝑡⁄ maximum
in winter. In this study, monthly salinity pattern is computed due to wind
stress through COHERENS, a three – dimensional sigma-coordinated
model, is employed to perform the simulation. The obtained results and
salinity field output show that salinity patterns extracted from
COHERENS Model and real amounts cosely match. Based on the results
of the study, it seems that the changes of existing winds in indian ocean
area and oman sea have an effect on salinity changes in Persian Gulf that
occurs through the flow of water from Hormoz strait into Persian Gulf.

The Caspian Sea is the world’s largest enclosed basin of the water that
terms of oil and gas resources as well as its significant role in the areas of
shipping, trade, economy and its impacts on the neighboring countries
climate, has a very importance of international. On the other hand, rapid
variations in sea level, especially uplift the last few decades in sea water
surface had substantial social and economic consequences and caused
much damage in the coastal areas of Caspian Sea. Hence, evaluation,
modeling and prediction of water level fluctuations essential for the
comprehensive management of sea and coastal sustainable development in
this area. Therefore in the present research, models of various adaptive
neuro-fuzzy inference system (ANFIS) using the data measured monthly
sea water level in two coastal gauges of Anzali and Noushahr respectively
for 40 years and 14 years, in the of South Caspian Sea, have been
developed. Comparison of predicted values of water balance by final
models with measured values at each station and according to the statistical
indices of R2, RMSE and CE indicate that the adaptive neuro-fuzzy
inference system in learning and forecasting of complex and non-linear
behavior of the Caspian Sea is very good performance and can be
considered as a new approach for predicting the state of fluctuations in this
basin.

Abstract
It is important to understand the waves' climate to plan and design marine
structures in coastal zone. In this study, we have evaluated the results of
these models by the use of field measurements and the results of the global
models, ERA-Interim and Wave Watch III (WWIII). In the following, by
classifying the characteristics of the waves into three chapters, before
Monsoon, Monsoon and after Monsoon, the strengths and weaknesses of
these models are discussed for the future studies. The evaluation and
results of global models led to the provision of criteria for controlling wave
modeling in this area. The results show that the WWIII model has a better
performance in ocean wave modeling and ERA-Interim model results have
a higher quality in western wave modeling.

Abstract
Generally, ocean currents are generated by winds, density differences in
water masses caused by salinity and temperature variations, ocean floor
topography and earth’s rotation and gravity. These currents move through
the ocean and control the oceanic climate. In the present study, the
generation and effects of Tropical Cyclone Ashobaa on the Makran coastal
region was studied. On this account, the study was divided into three main
sections, including analysis of field measurements, satellite images
processing and investigation of Hybrid Coordinate Ocean Model
(HYCOM) results. Field data analysis showed that sea surface temperature
and current speeds were both increased during Tropical Cyclone Ashobaa
occurrence, while satellite images processing indicated that water surface
temperature get colder at the same time. Investigation of HYCOM model
results clarified that while the storm was occurred, warm water flowing
was moving through Indian and Pakistan coasts and finally, Makran
coastal region was affected by the warm water.

Abstract
One of the important problems in ports is sedimentation in access channels
and variations of coastline and sea bed, So that dredging for the optimal use
of port has considerable price. One of the most important problems in coastal
engineering is sediment transportation; because sometimes the lack of
residual materials show the existence of erosion in the region and in other
points association of sediment , indicates sedimentation. In this research at the
first , on the basis of field observations, it was found that the coasts in the east
of Bandera Lengeh are very rocky and mountainous in parts, and the role of
an uncaused echo system (fen) in the trap The control of seasonal precipitation
floods in the upper reaches of the region indicates that the sediment
production capacity in the region is negligible and, according to these
evidences, it can be concluded that the amount of sediment transmitted from
the land to the sea They are inconsiderable. Then, comparing two aerial
images with a nine-year interval, coastal variations in Bandarlenghe area has
been evaluated, which shows that the modal line, and consequently the coastal
pattern, has not changed significantly over these two years and then using
LITPACK software related to DHI, and applying waveguide, tidal flow and
sediment gradient through sampling and output of ECMWF and MIKE21-SW
models ,to model sediment and coastline In the study area, the net result of
the sediment transport rate obtained from the LITDRIFT model, taking into
account the wave and current of 6186 cubic meters per year, is low, indicating
that the coasts around Lengeh port There has been no significant change over
the past years. Due to the low sedimentation rate of the studied area, about 2
millimeters per year and access to infrastructure facilities; this is one of the
most optimal places to constrauct or develop a port in the north of the Persian
Gulf.

Abstract
In this paper propulsion performance of a spanwise flexible oscillating
wing which is broadly similar to undulation of fin fluke is investigated.
The geometry of the fluke was simultaneously undergoing of three
harmonic oscillating motion while surging with constant velocity. The
effect of deflection phase angle, flexibility parameter and wing tip
deflection amplitude in thrust coefficient and swimming efficiency was
studied. A low order unsteady panel method coupling with a time stepping
algorithm for free wake alignment is implemented into a computer
program to estimate propulsion efficiency of lifting bodies. This is an
efficient method to accelerate computational speed via reducing the order
of problem from R3 to body boundaries. The results present the significant
effect of phase angle in propulsion characteristics of oscillating fluke.

Abstract
The present paper is devoted to the 3D numerical study of unsteady cloud
cavitation around the CAV2003 benchmark hydrofoil using a passive
cavitation controller method called cavitation-bubble generator (CGs). We
investigate this passive controller on the hydrofoil surface to affect the
whole processes of vaporization, bubble generation and bubble implosion.
Firstly we simulate the unsteady cavitating flow around the hydrofoil
without CGs using a Partially-averaged Navier Stokes (PANS) method.
The turbulence approach is coupled with a mass transfer model which
implements to an open source finite-volume package. Then we tested
different sizes and angles of CGs on the hydrofoil surface. The results of
an appropriate design of the CGs shows a significant decrease of the
maximum length of the attached cavity and a large decrease of wall-
pressure fluctuation intensity on the hydrofoil surface.

and finite element methods have been created using Tribon, OpenFoam
and ABACUS softwares. Initially the interaction between the elastic
wedge water impact is verified, until a standard solution with optimized
answer for the ship hall water entry problem is found. In ship water impact
problems, dynamic effects and ship seakeeping behaviors are very
important. Strip theory has been used in Tribon software to estimate the
slamming probability and vertical velocity at forward sections of ship.
Finally, using the mentioned methods, stress and strain values can be
obtained in structure. It is important to know the values of these variables
in order to design the instruments.

Abstract
In recent years, more attention has been paid to the seakeeping forecast.
As fast as floating ships and vessels, the speed of the boat increases, the
significance of these calculations increases. The purpose of this study is to
Modify the Floating Point Factor (KB) so that the least impact on other
hydrodynamic coefficients of floating in its modeling is applied. For this
purpose, by designing a fuzzy system, the floating body lines were
modeled at three angles of 120, 150, and 180 degrees in the range of KB
2% + and 2% coefficients, and the floating geometry lines were made for
each Modification and the Seakeeping functions (including Heave, Pitch,
Roll, AddedResistance, and MSI) Each body shape is calculated at each of
the angles. Then, the changes of each of the Seakeeping functions were
calculated using the mathematical modeling of polynomial fitting and the
optimal KB value was calculated using the multi-objective optimization
method of the genetic algorithm. The method presented in this paper is
implemented and tested on a Cruise ship, and the results obtained from
simulating Hull form lines in optimal KB and comparing its Seakeeping
function with the original model proved the efficiency of the proposed
method.

Abstract
The body of surface vessels is made up of intricate and special curvatures
to maintain balance, fight against drag, and avoid collision damage and
many other engineering considerations. In the construction of the surface
vessels body due to the complexity of the curves and the large dimensions,
the use of conventional forming methods is limited to more integrated
body production. So these parts are produced by connecting smaller
sections to each other. In this paper, a new method for forming a bulbous
bow is provided which has the ability to produce workpieces integrated.
For this purpose, a new die that has high flexibility in the production of
various parts was designed. This die includes side-by-side pins which are
adjustable height. By creating the proper arrangement and adjusting the
height of the pins, different geometries can be created. In order to form,
the sheet is closed on a die which mounted on a numerical control device,
and a spherical head tool connected to the device, on a continuous path
that is part of the geometry of the piece, moved in contact with the sheet
and formed the sheet. The results of this study showed the repeatability in
forming, high dimensional accuracy, and the speed of the new process.

Abstract
The current paper numerically investigates the side forces acting on
double-stepped planing craft in both zero and non-zero heel angles. To
analyze the problem, the Navier Stokes equations using Finite Volume
Method (FVM) are solved. Also, Volume of Fluid method is exerted for
modeling free surface effect. Due to turbulent nature of flow around the
hull, the k-ε model is applied. Planing craft is considered in 0, 5 and 10
heel/drift angles. Mesh study has been conducted and in order to assess the
validity of the presented simulation, results of the current simulation are
compared against Dominic Taunton’s experimental data and good
agreement is displayed. The aim of the current study is to compute side
forces acting on double-stepped planing hull at asymmetric condition. The
computational results suggest that, an increase in drift angle may lead to
an increase in yawing moment at constant heel angles. Also, the computed
contours of the wetted surface area, water spray, and wave pattern around
the hull as well as the sway force coefficient are presented and analyzed.

Abstract
The use of new bodies in today's vessels is very useful for responding to
ever-increasing needs. Realizing this, it will facilitate the achievement of
goals such as increasing the stability and speed of the vessel. One of these
emerging body forms is Catamaran vessels. This type of vessel has two
underwater bodies and an intermediate deck. One of the most important
steps in designing vessels is to find loads on their bodies during their
lifetime and time of specific operations. These times have different causes,
one of the most important of which is the waves. The tensions and
deformations created in the vessel due to these loads can be effective in
designing sheets and reinforcements and other structural elements of the
vessel. This paper describes the process of modeling the hydro-elastic
catamaran vessel step-by-step, which includes numerical analysis in
software and experimental testing in towing tank.

Abstract
The main goal in designing two body high speed vessels is the
development of a vessels with proper seakeeping in frontal impact with
waves in high speed traveling. This issue gain more importance when pitch
motion, immerging the vessel in the water and structural dynamic loads
in two body vessels with small waterline including swatch vessel increase
suddenly in harsh sea conditions and high travel speed in comparison with
one body vessels. This issue threat the safety and welfare of the crews of
this vessel. Several solutions suggested for improving the performance of
swatch vessels in high speed. One of these suggestions is modifying the
body form of the vessels. In this report, a modified body of a swatch
buoyant which called semi swath has been simulated and required
hydrodynamic studies include predicting the strength, the forces acting on
the body and heave and pitch motions on this body has been performed.
Hydrodynamic reaction of the two bodies and effect of these bodies on
each other has been obtained by simulating a semi swath vessel and
comparing it with a full vessels. Effect of the distance between the two
body on the strength of the vessel and on the dynamic movements of the
vessels has been investigated.

Abstract
Design and construction of multi-hull vessels is one of the important goals
of the future of surface vessels. In this way improving the dynamics
behavior of these vessels using appropriate design techniques can have a
profound effect on the road ahead. Side hulls in multi-hull vessels have a
lower percentage of total resistance but with proper design, they can play
a significant role in reducing overall resistance and improving dynamic
behavior. In this paper using numerical simulation of a trimaran surface
vessel movement with different forms of side hulls is investigated. Side
hulls in tree forms of inboard, outboard and symmetric are placed in close
up main hull and in each case, the overall resistance, trim and sinkage are
calculated. Simulations are performed using of star CCM software and
solving RANS equations in calm water and different Froud numbers and
results compared with experimental data. According to the results, side
hulls with symmetric form have better hydrodynamic behavior and less
overall resistance.

Abstract
In this research, in order to evaluate the performance of aluminum alloy in
radial boats exposed to sea water, the effect of speed on the corrosion
process of this alloy under cathodic polarization under flood conditions
using rotary cylinder electrodes by scanning electron microscopy and
electrochemical impedance spectroscopy in chloride Sodium 3.5% has
been investigated.
The results of the studies show that in the studied conditions, the main
process of rupture is local corrosion that occurs around iron-containing
cathode-intermetallic particles as a result of the concentration of
resuscitation reactions on these metals and severe alkalization around
them. . Finally, the results showed that under static conditions the
corrosion resistance decreases for the cathodic polarization sample, with
the growth rate of the cavities dropping only at -0.9 volts. On the other
hand, in silane conditions, with the passage of time, the 1-volt potential
improves corrosion resistance.

Abstract
Obtainable Service speed of a ship in real weather conditions when sailing
on a given shipping route, is one of the major parameters which have great
impact on ship operation costs. so far, approximation methods of service
speed based on “service margin”, have been less exact. In this thesis a new
method based on additional ship resistance dependent on mean statistical
parameters of wave and wind occurring on a given shipping route, is
presented.In order to obtain the service speed, first resistance, thrust and
torque of a specific propeller is calculated and then by using the charts, it
is estimated. The hull of the ship is S-175, modeled and its calm resistance
is calculated in Maxsurf software using Holtrop approach. For additional
resistance for Bandar-Abbas to Japan route, which is devided by several
parts- special altitude for each zone is observed and then with specifing
wave spectrum of those zone with help of Motion module of Maxsurf, that
parameter is obtained. In this paper, the effect of variations in geometrical
characteristics (ratio of pitch, ratio of chord and number of blades) of the
propeller has been considered on the service speed of the ship. For this
purpose, tried to study the role of geometrical variations of the propeller
blade (NACA66) on the service speed of the ship, based on the blade
element theory.

Abstract
CB 7-Cu steel is a hardening martensitic stainless steel; its hardening
mechanism is characterized by copper-rich sediments. In this research, the
Friction Stir Processing, at a rotational speed of 600 rpm and a linear speed
of 80 mm / min, was used by a non-consumable tool made of rhenium
tungsten carbide with a shoulder diameter of 20 mm and a pin in the form
of an incomplete cone with a height of 1 millimeter and a large diameter
of 5 millimeters and a small diameter of 4 millimeters. After the Friction
Stir Processing, microstructural and electrochemical corrosion studies
were performed. The microstructural studies by optical microscopy and X-
ray diffraction showed that the application of the friction process caused
fine-grained and axial grains in the disturbance region, which was due to
dynamic recrystallization, and also the phase shift from martensite to
austenite. The results of electrochemical corrosion showed improved
corrosion resistance in the perturbation region than the base metal.

Abstract
Diesel engine is one of the most important propulsion in different
applications like automotive, marine, power generation, etc. Noise
emission of this engine causes a lot of problems and has different sources,
paths and emission manner, which demand different methods to control
engine overall emitted noise. Since exhaust system has a major part in
engine overall noise, in this work design of a muffler for non-silenced
exhaust system of OM457LA diesel engine has been carried out using
integrated simulation of combustion, gas exchange, heat transfer and noise
emission in GT-Suite. Results of this simulation has been validated by
experimental data and has been employed to execute a sensitivity analysis
for optimization of design parameters. Designed muffler is a passive, three
chamber one, which has a circular cross section. As an example, results
indicate that for rated speed of 1800 rpm, using each suggested little and
big mufflers the overall exhaust system emitted noise, could be reduced
from its initial value of 114 dB, to 92.8 and 87.5 dB respectively. Also for
other speeds, remarkable reduction of noise could be achieved. All of
these noise reduction has been achieved with sacrificing just about 1% of
power.

Abstract
In many CADD computing tools (CASD), NURBS computing has been
introduced. To produce different body forms, a large variety of ship hull
forms can be obtained. In the case where only part of the body needs to be
optimized, the optimized area can permanently link the main body without
degradation By maintaining the operating system, various geometric
constraints can be easily implemented in the optimization process. In
addition, a NURBS based networking tool is designed to break the body
form and produce the mesh needed to simulate CFD flow around the body.
The hydrodynamic design of the ship consists of several steps, from the
initial design and the initial stage to the final design. Measuring the tension
and / or ultimate tension. Although SSF is a highly efficient CFD tool, the
need to optimize the body shape for several design speeds by reducing
computational time has led to the development of an approximated model.
The response level of a problem that is limited to a single target function
is directly evaluated by CFD. Based on the response level, the variable
analysis function (ANOVA) is designed to analyze the importance of each
of the problem variables. In order to obtain the optimal body form response
level, optimization using evolutionary algorithms has been used.
Computational tools developed in this paper, integrated CASD, CFD and
provide optimization techniques to optimize hydrodynamic guarantee the
hull form geometry. The application of the proposed method in a real ship
(Wigley) suggests that the current tool is an effective and inexpensive way
to optimize body shapes at the initial design stage. It also provides useful
analysis of the importance of different design variables.

This paper addresses the problem of actuator fault detection for a Remotely
Operated Vehicles (ROVs) widely used in underwater missions. The study
of ROVs’ open-loop and close-loop behaviors under thrusters’ failure can
bring us a bright sight into the ROV’s operational conditions. So, thruster
dynamic responses have been experimentally extracted to have a more
accurate thruster model. Then, dead zone and saturation dynamics which
are the most dominant thruster dynamics are imported into the simulation
model. Also, some scenarios are simulated to investigate the ROV’s
motion performance under healthy and faulty conditions in both open-loop
and close-loop operational modes. The simulation results express that, in
the open-loop condition, distribution of the force under faulty condition
influence on ROV’s motion behavior. Also, those inform us the PID
controller can regulate ROV under both healthy and faulty condition.

Abstract
The main difference between the underwater explosion and the usual
explosions (explosion in the air) is the dynamics of explosive products. In
a underwater explosion, the gas mass produced by the explosion produces
a special pressure field in water, which includes a primary shock wave and
secondary pulses. This paper studies the parameters of near-underwater
explosions and its effects on the structure by Lsdyna software numerical
solution, which has high ability and efficiency in the simulation of
underwater explosion phenomena and structural - fluid interaction
problems. The propagation of the underwater explosion wave in the fluid
medium and the transfer of the wave pressure in the fluid on the structure
are modeled using a multi-material Lagrangian-Eulerian method. Then, by
comparing with an experimental experiment, the error rate is obtained and
the software is validated. The following is a parametric study to Effect of
different reinforcement models on increasing the strength of steel plate
failure and checking the optimum cost of reinforced plate welding. The
method proposed in this project is capable of recording explosive shock
without the need for a very small element and provides a thorough
understanding of the prediction of the effects of the early response of near-
underwater explosions.

Abstract
The application of metaheuristic techniques to design different Hull ships
in research and industry has seen remarkable growth. The output of these
techniques is to obtain the Hull ship lines in recent years. The research is
based on two parts of the simulation of the initial model, the construction
of different models, and the optimization of the parameters from the
produced samples. In this paper, a hybrid model involves the modeling of
effective hull form coefficients including CWP, CB, CP, LCF, CM, KB,
and L, with the design of a Back-propagation neural network and
mathematical modeling of variations of the Seakeeping functions;
influenced by models made from variations of each of the hull form
coefficients with polynomial matching method and finally optimization of
the modeling functions in the previous step using a multi-objective genetic
algorithm and its combination with the PROMETHEE fuzzy algorithm are
presented. Optimization involves optimizing the seakeeping parameters of
the fast attack craft body including Heave, Pitch, Roll, AddedRsistance,
and MSI in the Oman Sea. Finally, the hydrodynamic parameters in
the optimal state of the seakeeping functions are specified and the Hull
ship lines are modeled in accordance with new parameters. The new model
has been optimized for seakeeping performance.

Abstract
International monitoring organizations and national environmental
organizations of many countries are working to reduce greenhouse gas
emissions and pollutants in marine resources through legislation and
regulations. Therefore, the shipping industry faces challenges to reduce
emissions from the engine and greenhouse gases from ships. In this study,
the feasibility of the use of natural gas as an alternative fuel for marine gas
and its parameters affecting emissions are investigated. In order to
investigate the effect of alternative fuels, a thermodynamic model for
turbine has been developed and then its performance for diesel and natural
gas has been compared. The results show that the use of natural gas as a
hydrocarbon fuel has the thermodynamic performance close to diesel fuel
and its thermal efficiency is lower than diesel fuel. Paying attention to the
importance of emission levels and the cost of fuel used in propulsion
systems, natural gas engines are far more polluting and cost less fuel than
diesel engines.

Abstract
This paper contains the numerical and field test investigation of
hydrodynamic force and moment on autonomous underwater vehicle near
free surface. When the body moves near free surface, it faces different
hydrodynamic condition in relation to the open water case. Better control
performance was gained with considering this condition. Current
investigation shows the numerical hydrodynamic simulation on different
depth which calculates the force and moments on body during steady state
motion in a fix depth. This condition describes the steady motion of body
near free surface. The hydrodynamic force and moments on body are
calculated in velocity and depth criterion of 2-5 meter per second and 0.4-
2.5 meters respectively. The numerical results in accordance with field test
show that increasing of body axial velocity near free surface; make an
increasing-decreasing trend of normal force value and changing moment
sign. So, the control effort of the system would be decreased.

Abstract
One of the most important and applicable features of a fighter, naval ship
and other military equipment is theirability of being stealth from
radarobservation so that to beundetected from enemy radars. Reducing the
radar cross section is very essential for amilitary equipment like fighters
and bombersand ships since it makes them more survival and increase their
ability to make maximum damages to enemy. Successful examples of
stealth bomberare B-2 and F-117(made by USA) and in naval field are
destroyers like Visby and Zumwalt(respectively made by Sweden and
USA). One of the most important way of reducing of radar cross section is
shaping of object body, so in this paper,suitable geometrical shaping above
freeboard of a corvette classship was proposed forRCS reduction based on
the recent advanced naval ships. After shaping of the corvette hull,it’s RCS
was calculated by CST-MS software. Results show that the corvette new
hull radar cross section was reduced considerably.

Abstract
One of the important steps in the design of submarine vessels is the
determination of forces and hydrodynamic moments on the float.
Hydrodynamic forces and moments include inertial forces, increased
mass, damping, crevillus, propulsion, and force and inhibitory moments.
In recent years, with the advancement of computer science, numerical
methods (CFDs) have been increasingly used in submarine industries. The
high accuracy of numerical methods has increased the use of these
methods in determining the resistance and propulsion force of submarine
vessels. In the present study, we have calculated the two groups of
damping coefficients of a subsurface float model using numerical method.
To calculate damping coefficients, uniform tests with angle of attack and
deviation were used by AnsysCfx software based on finite volume method.
When the object moves with the angle of attack or deviation to the current,
the variation of the drag coefficient in terms of these angles is a parabolic
function and this way it is possible to calculate nonlinear damping
coefficients. Also, using the force and torque diagram of damping on the
object, in these states, linear damping coefficients can be calculated. The
results obtained from the numerical method are compared with the results.
The relatively good results show the accuracy of the numerical method
used in the hydrodynamic calculations.

Abstract
In the present study, the reliability evaluation application in design and
maintenance has been investigated for the ship hull. In order to evaluate
the structure strength, the extended model of ultimate limit-state of hull-
girder regarding corrosion defect has been used based on probabilistic
analysis that depends on time. The time-dependent reliability has been
evaluated using minimum elastic section modulus required; this process in
the case of fatigue in ship deck has been done using S-N curve. The results
from the reliability evaluation using Monte-Carlo and first order reliability
methods (HL-RF), indicates that these two methods match very well.
Analysis of corrosion defect reliability shows decrease of the structure
reliability during its lifetime, hence one can use the reliability criteria in
design phase in order to reach a better perception of structure operation
during its lifetime regarding environmental conditions.

Abstract
Body optimization is one of the most attractive areas in all scientific
research, design and construction of ship. Create fair hull form is an
important optimization issue in the body design. This paper developed an
automated software for create fair hull form from the initial unfair hull
form. The proposed optimization method is based on a swarm intelligence
algorithm which the fair of curve surface as the target function and the
unfair curve points are selected as problem variables. Also, constrains were
made to ensure the fix hydrostatic coefficients and tonnage in the final
body form. In the following, to solve this non-linear problem, we use the
Teaching-Learning-Based Optimization (TLBO) algorithm, as one of the
most efficient meta-heuristic methods based on swarm intelligence
algorithm. To illustrate the efficiency and capabilities of the proposed
method, this method was applied to various samples body lines, which
were manually disturbed. The new curves, compared with their initial
curves, shows this method is a very good agreement by maintaining the
hydrostatic properties of the body.

Abstract
The problem of proposing is one of the most important parameters that
has been taken into consideration during the recent years in planning
vessels, and solving this problem has attracted the attention of many
researchers.
In this paper, the problem proposing of a stepped planning vessel by the
switching of engines has been investigated. At the same time, the
fluctuation phenomenon in the intake of engine water and the increase in
engine temperatures have also occurred, which has made the problem more
complicated.To solve this problem, the hydrostatic and hydrodynamic
state of the planning vessel has been studied and compared with the
previous and current engine in different conditions.
Then, by installing a lifting level at different angles, the effect of this on
the planning vessel behavior was investigated, which resulted in a
significant reduction of the proposing.Resistance, power and variation of
planning vessel trim in different conditions are calculated with Max surf
software and then compared with the test results.
The results have shown good agreement between experimental and
numerical results.

Abstract
In this paper, a practical procedure is demonstrated to calculate
hydrodynamic coefficients using computational fluid dynamics. Strategy
in current pages is to use a specific combination of preexistent methods by
the prospect of minimizing numerical costs such as applying single mesh
topology for all maneuvers, hybrid mesh, near wall treatment function, and
moving reference frame. The key to this goal is to use a single mesh
topology to simulate various maneuvers without concerning about
boundary conditions and the shape of numerical domain. Steady motion
tests such as rotating arm, pure roll, and rectilinear towing tests can be
simulated with a single grid topology by inducing translational and
rotational motion through moving reference frame method. Owing to these
maneuvers, the damping type of hydrodynamic coefficients can be
obtained. Two-equation RANS turbulence model 𝑘 − 𝜀 is used for
simulating turbulent effects. Hydrodynamic coefficients of various
configurations of SUBOFF model geometry are evaluated applying this
procedure. Comparison with other numerical studies shows the efficiency
of the proposed procedure. Validation of computational results is done due
to comparison with experimental data reported in literatures. It shows
acceptable accuracy of the procedure in engineering applications.

Abstract
Commercial and Military Ships require an electrical energy source for their
lighting and machinery loads whilst berthing. If this energy be provided
by on-ship diesel generators, it pollutes the seaport area considerably. To
prevent that, modern seaports are equipped with electrical source plugs
that connect to standards plugs on ships and provide their required energy.
This type of connection brings about new consequences for electrical
networks on ships and in the seaport as well. These consequences include
TOVs (TOV) due to switching, lightning and ferroresonance in cables, all
can have destructive effect on insulation of transformers and cables. This
phenomena becomes more considerable regarding military ships, since
they need a lot higher reliability in their electrical networks. In this study
EMTP software is used to simulate all elements of electrical connection
system between a ship and the seaport in transient state. Using medium
voltage surge arresters with optimized parameters in particular points of
this network can control the TOVs and keep them in standard range. In
addition, impedance drive starters can restrain the over voltages due to
starting current of motors. Optimum places to use surge arresters and
impedance starter drives has been found in this study and according the
results, TOVs could be limited in standard range.

Development a conceptual model to floating hotel
Hosein Javanmardi Masters in ship structure, Sharif University of technology;
Abstract
Floating marine hotels are a new subject in the maritime industry around
the world, and so far no analytical studies have been carried out either
inside or outside the country. In the present paper, a model of the floating
hotel and the geometric properties of this structure are presented. The basic
hydrodynamic analysis of the structure is presented using the BEM
method. The purpose of this analysis is to obtain hydrodynamic
coefficients arriving from the sea environment and analyze the behavior of
this structure. It is only here that the heave motion of the construct is
optimized. The cylindrical body of the hotel is not very conducive to
hydrodynamic behavior, but by adding a disc to the below, heave motion
can be decreased by increasing the mass coefficient and damping
coefficient. Also, by changing the dimensions of the disk and its
immersion position relative to the water surface, it can be shown that by
increasing the disk diameter and increasing the depth of immersion, the
hydrodynamic coefficients will be larger and the domain of heave motion
will be smaller. The resonant frequency and its position is improved in
comparison to the cylindrical body.

Abstract
One of the most important steps in designing vessels is to find the loading
applied to their bodies during their lifetime and the time it takes to perform
specific operations. These times have different causes, one of the most
important of which is the waves. The tensions and deformations created
on the vessel due to these loads can be effective in designing sheets and
reinforcements and other structural elements of the vessel. Various
methods have been developed to obtain responses for movements and
loads caused by waves and their estimates over the past 50 years. These
methods are needed to improve the performance of design tools used to
estimate loads and movements that have had a significant impact on the
reliability of the operation and safety of the structure. In this regard, the
present paper reviews the methods of structural analysis of Catamaran
vessel with a numerical and experimental approach. Considering these
methods is helpful in choosing the most suitable path for analysis along
the desired parameters.

Abstract
Today, conventional marine propellers remain the standard propulsion
mechanism for surface ships and underwater vehicles, due to the extensive
benefits of using them. A propeller is a propulsion device that creates
relative motion by forcing the environmental fluid axially backwards, by
means of azimuthally rotating blades mounted in a shaft that is driven by
an engine. A pressure difference is produced between the forward and rear
surfaces of the aerofoil shaped blades, producing thrust that is transmitted
from the blades to the shaft, and finally to the vehicle through the engine
supports. One of the important parameters in the design of a propeller is
the rake angle. Rake is the slant of the propeller blade with respect to a line
perpendicular to the propeller axis of rotation. In this paper, the effect of
rake angle on the performance of a four bladed propeller, designed based
on B-Wageningen series was investigated numerically in free water. To
this end, the propeller was simulated at five different rake angles (50, 100,
150, 200). The results showed that by increasing the rake angle of the
propeller, both thrust and torque coefficients were reduced, while there
was not any significant change in the efficiency of propeller. Also the
results of two phase analysis of fluid flow in propeller, showed that the
amount of cavitation was reduced at higher rake angles.

Abstract
In this paper, the problem of water entry into two sections of two different
vessel is investigated, and for each of these sections, the values of the
pressure and vertical accelerations are extracted and compared, so that the
effect of cross section geometry on the distribution of pressure and
acceleration Vertical Determine. The comparison between the distribution
of pressure in various states shows that in any case, due to the change in
geometry, the distribution of current around the object has changed,
thereby changing the pressure distribution and pressure coefficient. For
validating the problem, the experimental results used in other papers. The
results show that the cross-sectional variable deadrise is due to better
geometry More optimal than any other section with a more appropriate
pressure distribution. Also, the results of this research can be used to
design the planning vessel, replacing sections constant deadrise with
variable deadrise. With this replacement, the lifting force will increase on
the vessel by increasing the pressure distribution parameter, which will
result in better vessel stability.

Abstract
Wave added resistance is a second-order problem and is highly dependent
on wave-wave parameters. Amplitude of this additional resistance is up to
30 percent of the ship calm water total resistance. There are several
numerical viscous and non-viscous method like strip theory, panel method
and RANS method. With respect to accuracy and cost calculations, 3-D
panel method is the best choice for analysis ship behavior in wave. By
using frequency domain Green's function 3-D panel method added
resistance of S-175 containership is computed by far filed and near field
approaches. To investigate the effect of wave incident and wavelength,
calculations are performed in different incident angle and wavelength.
Also by using an accurate and fast empirical validated method that have
recently been proposed, added resistance in head sea are calculated for
different wavelength and ship speed. Far field and near field results are
consistent with good accuracy. Numerical and empirical results are
compared with experimental that shows high accuracy results.

2Professor, Center of Excellence in Hydrodynamics & Dynamics of Marine Vehicles;
Abstract
Scaled model test in the towing tank is a common method to predict the
ship resistance in the calm water. The scale effects are dominant in these
tests because the Reynolds and Froude numbers of the model cannot be
equal to full scale simultaneously. There is sufficient knowledge about
displacement hulls that their speed ranges are limited in the most cases,
while inadequate published data is available for high speed crafts. The
influence of the model length on ship resistance is different for various
speeds and it should be studied in more detail. The extrapolation method
of model ship resistance to full scale for high speed monohulls is studied
in this paper. Resistance model tests of semi-displacement hull and planing
hull are performed for two different sizes. The frictional resistance
coefficient is calculated by ITTC57 correlation line and residual resistance
coefficient is derived in each case. According to the results it was
concluded that the major part of ship resistance is dedicated to frictional
resistance in low speed up to length Froude number 0.3 and length Froude
number more than 0.9. In moderate speeds that is of interest for semi
displacement hulls small portion of hull resistance is dedicated to frictional
resistance and model size has small influence on the residual resistance
coefficient.

Abstract
At present, there are various forms of vessel underwater geometry
currently used in the design of mono-hull and multi-hull ship structures.
The use of new bodies such as HARTH vessel, aims to achieve such goals
as increasing stability and speed of the vessel. One of the most important
steps in ship design is the prediction of ship movements in the waves of
the sea. Dynamic performance of ships can be demonstrated using vessel
response amplitude operator (RAO) charts. This paper first introduces the
Harth vessel and features it to other mountaineers. In addition, the dynamic
performance of the Harth vessel and the mono-hull ship and catamaran by
the RAO diagrams of these vessels extracted from the ANSYS AQWA
software It is also compared. Advantages of the Harth vessel, including
low resistance, reduced engine power due to reduced wave resistance,
speed at high sea waves and proper seawater specifications, has made
research into this body shape one of the favorites of researchers.
Accordingly, they are referred to as next-generation vessels.

Abstract
The main difference between the underwater explosion and the usual
explosions (explosion in the air) is the dynamics of explosive products. In
a underwater explosion, the gas mass produced by the explosion produces
a special pressure field in water, which includes a primary shock wave and
secondary pulses. This paper studies the parameters of near-underwater
explosions and its effects on the structure by Lsdyna software numerical
solution, which has high ability and efficiency in the simulation of
underwater explosion phenomena and structural - fluid interaction
problems. The propagation of the underwater explosion wave in the fluid
medium and the transfer of the wave pressure in the fluid on the structure
are modeled using a multi-material Lagrangian-Eulerian method. Then, by
comparing with an experimental experiment, the error rate is obtained and
the software is validated. The following is a parametric study to determine
the effect of Cooper-Symonds coefficients on strain rate problems, Effect
of materials on plate dynamic behavior, Relationship between plate
strength and failure and Effect of plate Geometric Parameters on failure.
The method proposed in this project is capable of recording explosive
shock without the need for a very small element and provides a thorough
understanding of the prediction of the effects of the early response of near-
underwater explosions.

matrix form and, by deducting the space for the standard equipment
location, receives the user of the shape and amount of space needed to be
placed on the deck, and after implementing the standard steps of the
algorithm Genetically, considering the assumptions concerned, the user

Abstract
Suspended particles of dust and moisture in the air and passing from the
body of the electronic systems of marine systems cause problems in the
performance of these components and cause problems in their proper
functioning. The IEC in its publications lists the two above-mentioned
properties for the electrical device body by means of two numbers. The
first digit indicates the degree of protection of the device against the entry
of foreign bodies into the body, as well as the contact with electric or
moving parts, and the number The second indicates the degree of
protection of the device against the penetration of water into it. The two
above-mentioned numbers are used with two IP letters, which, according
to the definition of IEC, replace the word INTERNATIONAL
PROTECTION. For better performance, longer term and less tolerance of
electronic systems in marine vessels, as well as doing the right behavior
with them, they should have the degree of protection of each. The purpose
of this paper is to provide some methods for determining the degree of IP
protection in accordance with marine standards. This causes the body to
be exposed to dirt or dust if it is necessary to do so, and if this level of
protection is low, then it will be necessary to think of it. Prevent equipment
breakdown.

Abstract
Surface is one of the most important parts of different tools and

several another specifications of surface. In high speed submarine, super-
hydrophobic surfaces can improve the different qualities of surface such

oxide because of good properties such as self-cleaning and photo-catalytic

Abstract
The series of new antifriction self-lubricating composites on base of
thermoplastic of our own invention (molecular composites). The friction
and wear of molecular composites, sliding against iron, were investigated
in different conditions by a reciprocating tribometer. The physical
mechanical properties were measured by standard tests. The tribological
characteristics of molecular composites were determined by applying to
iron several composite specimens of advanced compositions, containing
friction modifiers. With water present in the experimental cell, friction and
wear are effectively reduced. The composites were used in order to make
a model specimen of tube bearing stern. The analysis of the work our
bearing was made by using the experimental set for the study of parametric
oscillations of ship shafting. The set is universal and allows studying the
longitudinal, transversal and torsional oscillations. The results of the
calibration load of the node are exposed. As a result of testing the new
material for the stern-tube bearing, based on molecular composite, is
concluded that the new material conforms to the requirements of materials
for stern tube bearings.

Abstract
Pitting as one of the most destructive types of sweet corrosion happens due
to crude oil/ natural gas production in pipeline environment. It causes
thinning in pipeline wall thickness and consequently, causes decrease in
pipeline strength against operational and environmental loading which in
some cases lead to pipeline bursting. The current paper, reviews the most
popular empirical models for estimating maximum pitting depth and then
the health and integrity of a pipeline located in South Pars is assessed
considering two statuses; intact and corroded based on DNV, API and
ASME codes. Finally, in order to investigate effect of pitting on the
pipeline design parameters, sensitivity analysis is carried out. It concluded
that pitting as an ineligible effect on health and resistance of a pipeline
against bursting and operating pressure and pipeline wall thickness are the
most effective parameters on pipeline failure.
Keywords: Subsea pipeline, corrosion, probability of failure, bursting

Abstract
In water construction projects, river engineering, and irrigation and
drainage engineering, it is vital to estimate the accurate volume of the
sediment transported by rivers. As the sediment transport phenomenon is
an immensely complex problem, therefore presenting an appropriate
solution for precise evaluation of the suspended load in rivers is tedious
and the mathematical models are not also accurate enough to be applied.
Nowadays application of artificial intelligence systems has been
developed as a novel solution in analysis of water resources problems. In
this research, the Adaptive Artificial Neural Network (ANN) and fuzzy
models were utilized to determine suspended sediment rate of Jagin River.
Correlation coefficient (R2) and Root Mean Square Error (RMSE) are
considered the model's assessment criteria. The results show a higher
accuracy of fuzzy model assessments in comparison with neural networks
and sediment rating curve assessments and According to calculations done
by the software Abaqus, and determining the amount of sediment in the

Abstract
Tension-leg platform (TLP) is one the proven technologies for deep
explorations. These structures are moored with pretensioned tendons to the
sea bed. So its integrity in harsh environment is vital. In the present study
a TLP is simulated in North Sea environmental condition in depth of 800
meters using MOSES software. Stress time histories are so obtained
utilizing 3-dimensional diffraction theory for intact tendon condition and
one tendon missing condition. Two conditions consisting 12 and 16
equivalent tendons are assumed for the structure. Reliability indices and
probabilities of failure are calculated with Rt software using Monte Carlo
simulation. It is seen that missing of one tendon drastically increases the
probability of failure. Also, increasing the number of tendons from 12 to
16 may lead to a better performance of the structure.

Abstract
In offshore field, several past studies reveal that most of collapse failures
are caused by lack of sufficient piles strength because loads are distributed
and transmitted through piles body. Therefore, scour phenomena affects
load transition and eventually pile strength. The necessity of the scouring
phenomena investigation emerges when the scour depth becomes
remarkable which can endanger jacket stability. In this paper, the simple
stepping up method of soil curves is used for the sake of regarding scour
by push over analysis of software SACS. A recently-built existing jacket
platform namely SPD 19C is opted as a case study. Results shows that
recently-built jacket platform RSR decreases with scour depth increasing.
RSR decreasing becomes more sensible as scour depth increases.
According to API RP2A collapse will be occurred in the range of RSR<
1.6, results show that at RSR=1.6, collapse will be occurred in the scouring
depth of 13.5m for recently-built platform, which approximately 27%
lower RSR than their original state. So scour protection methods should be
addressed in vulnerable areas as preventive alternatives.

Abstract
Sea surface oscillation depend on two reasons for the storm: the first cause
is the storm winds that, by introducing stress on the surface of the water,
causes the transfer of momentum to the surface of the water, and the
second reason is the drop in atmospheric pressure during the hurricane,
causing turbidity of the sea surface. This effect, commonly referred to as
the "pressure inversion effect", has been studied. In this paper effect of low
atmospheric pressure on fluctuations in water surface and wave height of
the Caspian Sea is studied. In this study, Caspian Sea Wind patterns were
studied for the year 2012 on a daily basis. For this purpose, wind data with
a 6-hour time interval of 0./125 The ECMWF data bank was used for one
year for 2012. From the results of this study, there could be a cyclone due
to wind in the southern part of the Southern Caspian Sea in the cold month
(February), also a cyclone due to wind on the southern shores of the
Caspian Sea in the warm month (August). The speed of the storm in
February was 9.26 m / s on 16th day, after 6 hours reaching 8.11 m / sec.
Also, in August, the storm speed is 2.6 m / s.

Abstract
In this paper, local scour below offshore pipeline under steady current has
been investigated by Flow 3D numerical model in different situations.
Then the results compared with similar physical experiments to evaluate
the reliability and quality of the Flow 3D sediment scour model. The
results show that the Flow 3D model can predict scour depth almost good
but it can’t simulate the scour shape and the downstream process of local
scour. Also, by conducting experiments for different gap ratio (pipeline
distance to bed on pipeline diameter G/D), the effect of pipeline gap on
scour depth is investigated. When G/D gets larger, scour depth and width
gets bigger and the scour shape centerline moves to downstream of the
pipeline.

Abstract
It is very important to study the behavior of semi-submersible platforms
that are used for drilling operations and extraction in deep waters. Due to
the importance and the role of mooring systems in limiting the platform
movements, in this study the effects of different mooring models as well
as the type of mooring materials on dynamic behavior response are
investigated and a numerical method is used to solve the coupled motion
equations for analyses the platform response. The results indicate that, the
change in materials has a great effect on the platform response such as the
effect of changing mooring model. Among mechanical properties, in
addition to weight, elasticity and hydrodynamic effects of the mooring
system, play a decisive role in this response. Increasing hardness by double
and weight density of materials by 50%; surge response, sway response
and heave response are reduced on the average 6%, 8% and 14%
respectively. It is also observed that in some cases the elasticity of the
mooring system is more effective than the weight and has more effect on
the platform response.

Graduated MSc, Engineering Offshore Structures, [email protected]
Abstract
Riser is one of the components of offshore platforms, Which consists of a
narrow cylinder that connects vertically from one side to the deck of the
platform and from the other side to the sea bed, And the transfer of oil and
gas from the sea bed to the platform. Marine risers are exposed to many
environmental forces, Which forces the oscillatory vibrations of the risers
in different directions, which are the so-called common the Vortex Induced
Vibrations, resulting in fatigue damage and shorter lifetime of risers. One
of the important issues with structures exposed to dynamic loads is the
accumulation of fatigue damage. Calculation of these stresses involves
checking the vibration of the raiser along the fluid flow and also in the
direction of the vertical movement of the fluid. In this article, the damage
caused by risers fatigue is based on the regulation API, Using finite
element method, Has been investigated and finally, the estimated useful
life of Riser against the fatigue phenomenon in the region is a case study.

Abstract
The DezhPod new Armour is a forge of the third generation of concrete
armour units, which is deployed as a single layer and random placement.
In order to develop this armor, it is necessary to test the physical model in
different conditions on it as well as in comparison with other similar
armour units. In this paper, the study of the DezhPod Armour hydraulic
stability and its comparison with Xbloc armour has been carried out by
performing physical experiments in the Flume of Tarbiat Modarres
University. A series of experiments with a scale of 1:51 has been done on
armor DezhPod and Xbloc and a scale of 1:66 was done on armor DezhPod
alone. The experiments show that both armor DezhPod and Xbloc have
been completely stable under 1.25Hs wave conditions. So that no blocks
were removed from the body of the breakwater. Separation of blocks was
observed for waves above 1.5Hs. Despite the separation of about 1% of
the fork blocks (9 Pcs), the protective layer was completely stable.
The results of the experiments show that the hydraulic stability of the
DezhPod unit is good compared to Xbloc Armor unit. Due to the low
porosity of DezhPod armour Layer, the amount of overtopping in sections
with DezhPod units is more than the Xbloc units.

Abstract
One of the safest and the most economical methods to transform oil and
gas is pipeline system. Prediction and prevention of pipeline failures
during its assessed lifecycle has considerable importance from industrial
experiences point of view. The dropped object is one of the accidental
scenarios in the failure of the submarine pipelines. In this paper, the
influence of the dropped object on a submarine pipeline located in near
platform of 19C South Pars gas field and having 32” diameter is considered
as a case study. According to the DNV-RP-F107- the probability of failure
analysis of the pipeline due to a dropped object- firstly, the impact
frequency is calculated. Secondly, the probability of damage due to box-
shaped object is determined by using energy transfer analysis and Monte
Carlo method. Annual frequency of failure of the pipeline is equal to
4.5×10-7 that is less than the rule-based acceptance criteria of 10-5. In
other words, this level of protection is safe for the pipeline.

Abstract
Single Point Mooring (SPM) is used as offshore mooring facilities for the
loading and unloading of oil and gas in the sea. In Iran, it is called briefly as
“floating buoy”. This offshore structure is fixed or floating. In this research,
floating type was discussed and it was fixed to the seabed with mooring chain.
In this study, mooring chain of SPM, which is considered one of the important
parameters of its design, in different environmental conditions will be
evaluated.. OrcaFlex Ver. 4.9e (UK) software is used for moorings analysis
that is related to the Orcina Company. For this purpose and to calculate the
environmental forces in the mooring chains (in our case 6 mooring chains
with 60 degree angle), the diffraction analysis and time history has been used.
The results show that, by decreasing and increasing the diameter of the
mooring, the force applied to the mooring also decreases and increases. Also,
the effect of chain diameter, direction, and amount of wave and current has
also been studied. The behavior of wave and current shows when the direction
of the wave and the current are closer to the direction of each mooring chain,
the force applied to the mooring increases. In this research, a case study of the
environmental forces of the SPM project was used to export the Azadegan
extra heavy crude oil in the Behregan oil terminal, which was carried out by
the Tehran Berkeley Consulting Engineers. By analyzing the SPM, the
minimum safety factor of the mooring force is calculated to be 2.67, indicating
the adequacy of the technical specifications and the mooring geometry against
the environmental forces.

Abstract
In recent years, many researches have been carried out to Localize ISO-
19902 standards for design of fixed steel offshore platforms in different
regions of the world. The use of API WSD standards is currently common
in design while the LRFD method, that consist of both partial load and
resistance factors, is expanding. In this regard there has been brief research
for the Persian Gulf region, so there is a huge vacancy for the offshore
industry of Iran. Evaluation of environmental load factors are usually
calibrated through Reliability analysis. In this type of analysis, the
performance of a structure is defined by the limit state function for the
critical mode of failure. In this paper, at first, uncertainties in load and
resistance are investigated and statistical parameters are obtained. Then,
using the structural component based reliability method, the reliability
index of the jacket platform cylindrical members were obtained and
measured with the values of the target reliability index, obtained from the
WSD method, and finally the factor of 1.28 for the Persian Gulf
environmental load has been set. This factor is lower than the factors
obtained for the Gulf of Mexico and the Mediterranean Sea, and is greater
than Indonesia and the Central and South North Sea, but close to the
Northern North Sea and Malaysia.

Abstract
The launching of a truss spar platform in conditions close to reality is
considered under regular wave power with zero degrees. In the launching
process, it is necessary to correctly predict all forces acting on the platform
and the barge and the trajectory of them to prevent problems such as
capsizing, collision or hitting of the platform to the sea bed.
The launching process is simulated by Moses software. Time histories of
the motions of the barge and the truss spar platform and the forces acting
on them are derived. The output graphs of Moses show the behavior of
platform and barge in every stage of the launching process. Comparison of
the results with other numerical results shows that the performed analysis
can be used as an aid for proper design of launching process, as the most
critical stage in the installation of the platform.

Abstract
In offshore structures industries, one of the most important construction
processes is related to structural welding. Therefore, one of the most
important steps in the construction of marine structures is the choice of
proper welding method along with the recognition of its features and
requirements. Among the various welding methods, Friction Stir Welding
method is one of the well-known processes that has advantages such as
low distortion, optimal microstructure, environmental pollution reduction
and the ability of aluminum metal welding in offshore and offshore
structures (for helium Deck was in it. Therefore, in this paper, after
presentation of the method of operation of this welding process, its main
characteristics are presented. Then, the role of welding speed and different
weld areas in this process has been investigated. Finally, the impact of the
welding tool and tool geometry in this welding method has been studied
extensively. One of the advantages of this type of welding process in terms
of fusing welding and common in the current industries of shipbuilding
and offshore is to reduce the distortion and reduce the post-heating
processes after welding and, as a result, the speed and quality of the
manufacturing process, Attention.

on the period of the structure. Five foundation models including: perfect
hinge and fix bases and more advanced models based on soil properties
including linear springs & nonlinear springs with strain hardening
plasticity models and a hinge base with linear rotational spring were
incorporated in F.E models of structure. The effects of these support
conditions on the maximum dynamic response are studied in detail.
From the results of deterministic dynamic analysis for the waves with the
heights 0.25 m to 12.25 m, it was concluded that change in the transient
response are extremely dependent on the nonlinearity involved in the
response which are due to numerous sources in the structural behavior such
as geometrical, soil-structure-wave interactions.

Mashhad; [email protected] Abstract
In this work partial and supercavitation over a sphere at a constant
Reynolds number of 1.5×106 and a broad range of cavitation numbers
(0.36<σ<1) was examined. Large eddy simulation (LES) and Sauer mass
transfer model were used to simulate the dynamic and unsteady cavitation
around the sphere. Also, the compressive volume of fluid (VOF) method
is used to track the cavity interface. The two-phase flow solver of the
OpenFOAM package, intephaseChangeFoam is employed. Large-eddy
simulation of cavitating flow over the sphere is compared with the non-
cavitating flow at the same Reynolds number. This work provides a
thorough understanding of the fluid dynamic characteristics of the sphere
cavitation such as turbulent kinetic energy, pressure, streamlines and
boundary layer. Also, detailed analyses of the instantaneous cavity leading
edge and separation point location, vortex shedding, streamwise velocity
fluctuation and evolution of the cavity are reported. We report that
cavitation suppresses instability in the near wake region and delays the
three-dimensional breakdown of the vortices. The volume fraction
contours of the cavity cloud obtained from the numerical simulations are
compared with the experimental data at the same working condition with
a suitable quantitative accuracy.

Abstract
Nowadays, researchers trying to use the energy of free waters through the
energy conversion devices. Vertical axis turbines are suitable instruments
for converting the energies of rivers, oceans, and tidals. Though Darrieus
turbine is very simple to construct, it has some disadvantages when
compared to axial turbines. These are a lower power coefficient and a
variation in the torque produced within the cycle leading to periodic
loading on the components of theturbine. One of the goals of this project
is increasing the turbine’s power factor with regards to decreasing the
ripple of the torque in one cycle. In this study, a crossflow vertical axis
water turbine (Darries) was simulated using computational fluid dynamics
(CFD). For improving the performance of the turbine, a convergent duct
was used around the turbine and the torque factor was measured at
different rotational speeds. In the tip speed ratio equal to 2 , highest torque
factor with regards to the lowest torque ripple of the torque diagram was
obtained. Power factor increased 16% by using the duct in this tip speed
ratio. Then changes in the torque factor by altering the parameters of the
blade’s profile was evaluated.

Abstract
In the present paper, a direct numerical simulation of drag reduction in a
turbulent channel flow rotating about its wall-normal axis with one
hydrophobic wall is presented. Three-dimensional and time-dependent
Navier-Stokes equations are numerically solved. To model the effect of
hydrophobic coating on the wall, a wall velocity slip condition is used on
the bottom wall. To validate the numerical code, an analytical solution is
developed and used. Then, the developed code is used to study the
turbulent channel flow at a shear Reynolds number 180 with rotation about
the wall-normal axis, at various Trostel numbers and a constant rotation
number. The results of the simulation are presented and discussed.

2 Professor, University of Tehran; [email protected]
Abstract
Currently, monopile is the most frequently used offshore wind turbine
support structure. This substructure consists of simple tubular sections
driven into the seabed and is suitable for a depth of 25 meters. The purpose
of this paper is to design, analyze and evaluate a monopile as a substructure
for an offshore wind turbine of 5 megawatts capacity in Dorood region
with a depth of 30 meters. Necessary analyses for evaluation of the
structures’ strength, displacement, and fatigue damage under wave, wind,
and current loading have been performed using SACS software and the
results were verified in ANSYS software. Subsequently, the feasibility of
implementing this structure in Iran has been investigated based on the
approximate costs of the project and the required facilities and equipment.
Preliminary design shows that for such an environmental conditions, a
monopile with 6.5 meters diameter and 38 meters penetration depth is
required. These dimensions challenge the current capacity of fabrication
and installation methods and vessels. The lack of these facilities makes the
project nonfinancial and costly in Iran.

2Assistant Professor, Civil Engineering Department, Sharif University of Technology;
Abstract
For evaluation of using wind and current marine renewable energies, as
co-located offshore energy farms, Persian Gulf waters near the Bushehr
province coast were selected. First, due to technical limitations, a specified
strip of depths of 20 to 35 meters and at a distance of 10 to 40 kilometers
from the coast was selected as a suitable place for the construction of co-
located farms. The required wind and current data were prepared using
related databases. Then the type and arrangement of turbines in each
computational mesh unit were determined. By applying the required
information and using the power calculation relationships on the
computational mesh, the results of the mesh are determined and mapped
by various statistical indices. In this method, in addition to the individual
evaluation of resources by mean annual extraction power, with using an
index, correlation between the powers of two different sources was also
determined and mapped. Finally considering synergy between energies
and with balancing different effective parameters, an index with the name
of co-location feasibility index was introduced. As result, with this index
different areas for the construction of farms was rated and suitable areas
for the construction of co-located farm was proposed by a map.

Abstract
Concerns about the global warming and environment pollution, as well as
loss of fossil resources, make renewable energies as an absolute necessity.
Ocean energy is an important kind of renewable energy which has been
extracted in various ways. Oscillating Water Columns (OWCs) installed
on the shore are one of the wave energy absorption systems which has been
paid attention due to its low operating cost and easy maintenance. In this
research, a fixed model of an OWC has been designed and tested in a wave
tank. The effect of variations in the wave frequency, draft (distance
between the water surface and edge of the front wall) and also diameter of
the air outlet have been investigated on the pressure inside the chamber,
the flow rate of the exhaust air and the pneumatic power. The results show
that increasing the draft and wave frequency to a certain value will increase
the pneumatic power and after that it will cause an decrement in the
pneumatic power. Moreover, according to the results for two different
diameters of the air outlet duct, it was observed that the pneumatic power
of the small one is bigger.

Abstract
In this study, the usage of Coanda effect and its performance for
underwater propulsion has been evaluated experimentally and
numerically. In this system, air flow amplifier part is used and called water
flow amplifier system and thrust is produced by putting the flow amplifier
system in water environment and pumping water instead of air. To evaluate
the performance of this system, at the first Bollard pull test has been done
and the results have been compared with numerical results using
computational fluid dynamics. Then a comparison has been carried out
between this system and the commercial propellers for non-zero speed
water. It has been shown that by using this system as a thruster for
underwater applications, the thrust can be generated about the same
compared with a commercial propeller with the same diameters. The usage
of this system as a thruster may be associated with some advantages, such
as lack of sensitivity to pollution and suspended particles in water, no need
to neutralize the torque generated by the rotating propeller and production
of propulsion without causing cavitation.

Abstract
The use of wind energy to generate electricity is an old and growing
industry. In recent years, with onshore wind farms being well-spread,
considerable attention has been paid to offshore wind farms development.
Due to the availability of rich offshore wind sources in the Persian Gulf,
necessity of fossil fuel deduction as well as the lack of fundamental
research in this field, the study of offshore wind turbines and their support
structures is essential. The objective of this article is to provide basic
knowledge regarding the history of offshore wind industry, the importance
and performance of the offshore wind turbines, different types of
substructures and their pros and cons, the investigation of economic and
executive issues related to the three fixed substructures. Selection of the
preferred option should be based on comparison and evaluation of
preliminary designs and overall weight of the structures, the cost of
fabrication and installation, availability of facilities in the yard, needed
equipment and vessels and previous records.

Abstract
In recent years limitations of non-renewable resources, high production cost and
also adverse pollution effects on the environment led us to renewable energies.
One of the most important renewable energy resources are sea-based energies and
water currents. So far different approaches are studied in order to use the sea-
based energies. One of these approaches is the use of wave energy and sea
currents. These very currents carry high amounts of kinetic energy. Obtaining
energy from sea currents is similar to wind energy harnessing. Therefore it has
been done by a turbo machine which is similar to wind turbine. Horizontal axis
turbines are the most common types of marine turbines which have a similar
design to wind turbines. Considering our country's sea-based energy potential and
capacity, the purpose of this paper is to design and simulate a marine turbine to
capture energy from sea currents. After some research on marine turbine we chose
a three bladed horizontal turbine and designed hydrofoil sections and its blade
pitch angles by the use of simulation. In the following, we evaluated the turbine's
performance by MRF modeling using ANSYS-Fluent software for different free
stream and rotational speeds. We reported estimated power and turbine's different
parameters which affect its performance in several situations. Finally we have
observed from the simulations that the most efficient AoA is 7 degree relative to
the hub. Also, the turbine power is reported at a flow rate between 0.5 to 2 m/s in
watts.

A fossil fuel power station is a power station which burns fossil fuel such
as coal, natural gas, or petroleum to produce electricity. Fossil fuel power
stations have machinery to convert the heat energy of combustion into
mechanical energy, which then operates an electrical generator.
This article concerns the type of floatable structure, on which a main power
of electricity generator is planted, which can be berthed alongside a pier
and connected to a national grid to supply electricity to a city. It is obvious
the owner/operator of this kind of floating structure might have had the
benefit of her navigation availability and usage by virtues of sending her
to any destination port where an urgent electricity supplier is in need.

Abstract
Today, usual submarines have Diesel-Electric system. In order to recharge
the batteries, submarine should moves up to the water surface several times
in order to be charged by its generator. This can be dangerous since the
submarine might be delectable by the enemy. So air independent
propulsion systems (AIP) are more preferable today. Such systems can
produce electric power to recharge batteries, propulsion system and also
other electric equipments under water situations. One of these AIP systems
is fuel cell in which the chemical energy of the fuel is converted to the
electric energy. The most important type of the fuel cells in this application
is proton exchange membrane fuel cell (PEMFC). In this paper a fuel cell
hybrid electric propulsion system is designed and modeled for marine
applications especially for submarines. Design and modeling is done with
COMSOL software. First the required polymeric fuel cell is designed for
propulsion system in a submarine with specified power range. By
determining all of the required parts in such system, the governing
equations for these parts are modeled consisted of electrochemical
equations and fluidthermal equations. This model can predict
electrochemical and thermo dynamical parameters in different operational
situations. With this simulation the user can watch the effect of different
parameters in the final operation and this can be helpful in better and more
precise designing before construction. The results show that parameters
like temperature and pressure have an important role in the system
efficiency.

Abstract
Nanosilicon is a sustainability suspension that is made by uniformly
dispersing nanoparticles in a fluid. Because of its high stability, particle
size and the inherent nature of thermal conductivity in solids, its thermal
conductivity has been improved considerably, so its application in
converters Thermal is good. Considering that nanosilicates that have better
thermal transfer properties and higher thermal conductivity will be more
suitable for increasing the heat transfer fluid heat transfer coefficient.
Examining their thermal properties as one of the important study and
experimental axes has attracted a lot of research in recent years. Has
attracted itself. The results show that increasing discharges and nanosilver
concentrations have a significant effect on increasing the transfer heat
transfer coefficient and the nanoparticle size used to create a nanosilial in
the range of 20-50 nm has a more favorable effect on increasing heat
transfer. The change in the temperature of the nano-fluid into the heat
exchangers in the range of 10 ° C does not affect the heat transfer
coefficient so much. If suitable conditions are provided, an increase of
about 60% -50% for the transfer coefficient of the nanofluids is reported
relative to the base fluid

Abstract
Multipurpose Amphibious Vehicles (MAV) and other blunt shaped
floating vehicles encounter the problem of a large bow wave forming and
hydrodynamic resistance at high speeds. This wave formation is
accompanied by higher resistance and at a critical speed results in bow
submerging or swamping. Three new shapes of hull bow design for the
multipurpose amphibious vehicle were conducted at several speeds to
investigate the hydrodynamic phenomena using Computational Fluid
Dynamics (CFD, RANS code), which is applied by Ansys-CFX14.0 and
Maxsurf. The vehicle’s hydrodynamic bow shapes were able to break up
induced waves and avoid swamping. Comparative results with the vehicle
fitted with U-shape, V-shape and Flat-shape of hull bow, showed that the
U-shape of the hull bow has reduced the total resistance to 20.3% and
13.6% compared with the V-shape and flat shape respectively.
Finally, the MAV will be supported using air cavity and bubbles generated
by an air pump (compressor and air pressure vessel) to pushes the hull of
multi-purpose amphibious vehicle up and reduce the frictional resistance
due to draft and wetted surface reduction and layer of air between hull
surface and water. This research would be done via CFD (ANSYS-CFX
14.0) and analyzed the hydrodynamic resistance changing.

Abstract
About 90% of the world's freight is transported through the sea, while
humankind is not well acquainted with men who have a huge share in the
world trade cycle. It should be noted that what is the interest of sailing in
the twenty-first century, in the world of humanity and in the process of
advancing towards globalization. To overcome the problems of the sea and
to properly fulfill the responsibilities, modern sailors should be trained,
healthy and mentally sound. The social life of seafarers is a complex life
and is influenced by their performance. The social environment of
seafarers has two main components: one in terms of work and living
conditions on board, and the other is related to distance from the family,
which, of course, are both interrelated and reduce productivity and increase
the risk of accidents and illnesses Gets. The purpose of this study was to
investigate the problems of seafarers in non-convension vessels. The
method was qualitatively and through non-structured interview (open). In
this study, the problems of living in the sea were identified and in the end,
suggested solutions were proposed to make the living conditions of
seafarers more appropriate.

Abstract
Improving the level of training of seafarers in non-Conventional vessels is
one of the major issues that should be taken into consideration because in
some of the ports and inland waterways most of the traffic is related to
these vessels. Also, the number of non-nuclear floats under the Iranian flag
is more than conventional harbors. In this research, we try to find out the
effectiveness of identifying the factors affecting the increase of the
awareness of the seafarers of these vessels, identifying the problems and
providing solutions to solve each of the problems, and finally, by providing
a solution A strategy to increase the coordination between these factors is
a positive step towards improving the level of training of non-
Conventional naval seamen, taking into account all aspects.
