ORIGIN OF THE CLASSIFICATION

In the 2nd half of the 18th century, marine insurers

developed a system for the independent inspection of the

hull and equipment of ships presented to them for

insurance cove. At that time, an attempt was made to

“classify” the condition of each ship on annual bases.

Without disturbing the insulation or coating

When insulation is aluminum, stainless steel or low alloysteel clad

While is in operation

When equipment is hot <500deg C or cold> -100deg C

When insulation is wet

When object surface is rough or encrusted

When insulation is rough or heterogeneous

When insulation is wire mesh reinforced

Page 29: Technical Elective ( BSMARE)

C. IRATA Rope Access

are similar to arrest techniques, in which full body

harness and twin ropes are used to gain access to

elevate worksite .

D. Ultrasonic Time of Diffraction

used examine welds in pressure vessels and pipe work

ToFD can be employed to carry out corrosion mapping

on pressure vessels and pipe work.

E. Rapid Ultrasonic B-Scan Inspection

used for real time detection of internal corrosion,

lamination, plate inclusions, blister and general wall

thickness loss of ferrous and non-ferrous materials.

Page 30: Technical Elective ( BSMARE)

F. Online & Offline Inspections

online Inspection typically consist of ultrasonic shell

crawler runs, and ultrasonic roof measurements while

Offline inspection consist of (Magnetic flux Leakage) of

the tank bottom plates.

Page 40: Technical Elective ( BSMARE)

THE IMPORTANCE OF NAVIGATION ,COMMUNICATION , FRESH WATER , WASTE DISPOSAL ,RUNNING RIGGING, ELECTRICAL, FUEL SYSTEM AND

SAFETY SYSTEM

Page 41: Technical Elective ( BSMARE)

NAVIGATION

is a field of study that focuses on the process of

monitoring and controlling the movement a craft or from

place to another.

FIELD OF NAVIGATION :

Land Navigation

Marine Navigation

Aeronautic Navigation

Space Navigation

Page 42: Technical Elective ( BSMARE)

IMPORTANCE OF NAVIGATION

Boats and ships are required to lights known as Marine

Navigation lightings, form a very important part of a

marine navigation systems. It does not have any

lightning system, making it all the more important to have

more navigation lightning system on ship and boats.

Page 43: Technical Elective ( BSMARE)

IMPORTANCE OF COMMUNICATION

Maritime must be able to communicate with other ships

regardless of the size or originating country. Today’s

mariners must be able to receive as well as send

important maritime information regarding safety either to

other ships or back to shore.

Page 44: Technical Elective ( BSMARE)

IMPORTANCE OF FRESH WATER

is generally produce on board using the evaporation

method. There are two things that are available in

plenty to produce fresh water-seawater and heat.

Page 45: Technical Elective ( BSMARE)

IMPORTANCE OF WASTE DISPOSAL

Pollution in the world’s ocean causes a significant threat

to life and is recognized as one of our highest

environmental concerns. While there are many sources

of marine pollution, one concern is ship-generated

waste. Depending on the nature of waste, international

regulations determine whether it may be discharged into

the ocean or disposed of on land once the ship come

into port.

Page 46: Technical Elective ( BSMARE)

IMPORTANCE OF RUNNING RIGGING

To keep your boat sailing smoothly and efficiently is

important to pay great attention to your running

rigging. It is the moving parts in the primary engine in

your boat.

Page 47: Technical Elective ( BSMARE)

IMPORTANCE OF ELECTRICAL

Prime over start up

Synchronizing of incoming machine with bus bars

Load sharing between alternators

Safety and operational checks on power supply and

equipment in operation

Unloading, stopping and returning to standby of

surplus machine

Preferential tripping of none-essential loads under

emergency conditions and their reinstating when

acceptable

Page 48: Technical Elective ( BSMARE)

IMPORTANCE OF FUEL SYSTEM

Helps in providing the accurate amount of fuel oil burn at

any particular vessel speed or rpm. This helps crew to

continuously measure and monitor the fuel, an extremely

important aspect when the ship as sailing.

Page 49: Technical Elective ( BSMARE)

IMPORTANCE OF SAFETY SYSTEM

To prevent human injury or loss of life, and avoid

damage to the environment, in particular, the marine

environment, and to property.

CORROSION

Metal posses the characteristics of disintegrating back to

their natural state . It is the gradual destruction of materials

(usually metals) by chemical reaction with their

environment.

Basic Components of Corrosion :

Anode

Cathode

Electrolyte bath

Page 76: Technical Elective ( BSMARE)

C. Galvanic Corrosion

Corrosion that occurs when two or more dissimilar metals

are place in unprotected contact or close proximity.

Accelerated decay from electric currents artificially endued

into the hull from extraneous source.

E. Paint and painting

- is made of two principles :

The pigment

The vehicles

Page 77: Technical Elective ( BSMARE)

TYPE OF CORROSION

A. Crevice Corrosion

has its inception in tight seams,

in narrow crevices, silvers or in

other tight places.

B. Pitting Corrosion

can be the most aggravating

type of corrosion if it is allowed to

start.

Page 78: Technical Elective ( BSMARE)

A. Pigment of Paint

defined as the minute particles of insoluble solids that

form the body of the paint and remain as hard opaque

surface after the liquid or vehicles has evaporated or

deteriorated.

B. Vehicle of Paint

is the liquid content which act as a binding agent between

the minute particles of pigment, holding them together as

well as to the surface of an object.

5 types of Pigments :

Red Leads

Litharge

Fume red lead

White leads

Zinc oxide

Page 79: Technical Elective ( BSMARE)

TYPES OF PIGMENTS

A. Red Lead

is made from metallic lead, by burning process.

B. Litharge

another form red oxide which is made up in the same

process but at different temperature.

C. Fume Red Lead

is a compound of extremely fine particles developed from

metallic lead by the heat and oxygen process used in

making regular red lead, but it is distilled instead of

burned.

Page 80: Technical Elective ( BSMARE)

D. White Leads

is made up of two separate processes; in the first,

metallic is corroded by acetic acid forming whitish

flakes, which is later ground to a fine powder. The

second process of making white lead sulphide ore by

the sublimation process.

E. Zinc Oxide

is a compound of zinc and oxygen, and is finest of all

white pigments.

SHIPS BOLIER DETAILS

& MAINTENANCE

Boiler

is a tank turning water to steam for heat or power.

it transfer the energy in fuel to useful work output.

Page 84: Technical Elective ( BSMARE)

TYPES OF BOILER

A. Scotch Boiler & Leg type

Boiler

have horizontal tubes.

B. Vertical Boiler

the tubes are installed in a

vertical position and the

combustion gases, after

passing through them, go

directly up the stack.

Page 85: Technical Elective ( BSMARE)

C. Fire Tube Boiler

is the earliest practical boiler, the essential characteristics

of fire tube boiler is that the products of combustion pass

through inside of the tube, with the outside of the tubes

being surrounded by water.

Page 86: Technical Elective ( BSMARE)

Advantages of Fire Tube Boiler:

They contain a large amount of water, so do not require

exacting supervision as regards water level.

The fire tube boiler can use impure water without serious

damage.

Their first cot is relatively low.

They are easily accessible for maintenance.

Because fire is on the inside of boiler and is surrounded by

water radiation losses are lower.

Page 87: Technical Elective ( BSMARE)

Disadvantages of Fire Tube Boiler:

Because they contain a large water, they require a long

interval of time to raise steam and are not so flexible as

regards change in steam demand.

They are more susceptible to explosion, and in such a

case, the large volume of escaping water flashing into

steam upon reaching the atmosphere might cause serious

damage to personnel.

Page 88: Technical Elective ( BSMARE)

Disadvantages of Fire Tube Boiler:

High steam pressure would require extremely thick boiler

plate, and those fire tube boiler are not usually capable of

producing steam at high pressure and temperature.

They require large containers in the fire room.

Typical efficiency is less than that of water tube boiler.

Page 89: Technical Elective ( BSMARE)

D. Water Tube Boiler

where is contain within the tubes with products of

combustion passing around outside of the tubes.

Page 90: Technical Elective ( BSMARE)

Advantages of Water Tube Boiler:

They can produce steam at high pressure and

temperature.

They are very flexible as regards changes in steam

demand because of their small volume of water.

Permit used of heat-reclaiming devices, and so are very

efficient.

Steam pressure can be raised in a relatively short time.

They are not liable to explosion.

They are assemble in the fire room, and so large

entrances into the fire room are not required.

Page 91: Technical Elective ( BSMARE)

Disadvantages of Water Tube Boiler:

They must use pure water.

They must receive constant supervision as regards both

water level and steam pressure.

Boiler must be heavily insulated to minimize radiation

losses.

To make repair on tubes, boilers must be emptied.

First cost higher than that of scotch boilers.

Page 92: Technical Elective ( BSMARE)

CHAPTER VII

Page 104: Technical Elective ( BSMARE)

THE SCOPE TO MAJOR MARKET

Demand states and marketing task *1 :

Negative demand a major part of the market dislike the

product and may even pay a price to avoid it-vaccinations,

dental work, and gallbladder operations, for instance the

employers have a negative demand for ex-convicts and

alcoholics as employees. The marketing task is to analyze

why the market dislike the product and whether the

marketing program consisting of product design, lower

prizes, and more positive promotion can change belief

and attitude.

Page 105: Technical Elective ( BSMARE)

Demand state and marketing * 2 :

No demand target consumer may be unaware of or

uninterested in the product. Farmers may not be interested

in a new farming methods, and college students may not

be interested in foreign-language courses. The marketing

task is not find ways to connect the benefits of the products

with people’s natural needs and interest.
