The ability to manage changes throughout the project, perform
concurrent work across disciplines, avoid duplication of
information and automate repetitive operations is imperative in
order to improve the competitive position in ship building. In a
sense, this all comes down to the same fundamental challenge –how to integrate people, companies, product information, work
tasks and project phases while maintaining the needed
flexibility for each person to work efficiently in individual
activities. The DNV Software MarineSolutions meets this
challenge, with integration throughout the project lifecycle as acornerstone throughout the application.
INTRODUCTION
Improving the yard’s competitiveposition all comes down to the
same fundamental challenge:How to integrate people,disciplines, phases, informationtasks and software into acoordinated force to design andbuild world class ships. TheDNV Software Marine Solutionsmeet thi s challenge, withintegration throughout theproject lifecycle as acornerstone.
Integration is not simply a technical issue, related to
application-to-application interoperability. More importantly, it
constitutes the foundation upon which important business
applications should be built. In this white paper, we will
describe the concept of integration both from the perspective of
the needs arising in the different phases in the ship design andengineering process, and from the perspective of the enabling
software architecture.
To set the stage more properly, the concept of integration
should be developed somewhat further:
• Integration means true multidisciplinary work towards thesame underlying model. MarineSolutions is developed from
the basis as such, where steel and various disciplines of
outfitting are represented in the same underlying product
model. This has obvious advantages in terms of interference
or collision checks as well as change management.
• Integration means that the same model develops incrementallyas the project develops. In MarineSolutions , information
created in the conceptual phase is the starting point of the
model that results when as-built information is completed and
handed over to the customer.
• Integration means giving access to critical analysis servicesthat employ the model under development, without having to
make explicit data exports or having the engineer enter into
another user environment. In MarineSolutions, analysis tools
for structural integrity, machinery or weight assessment are
available to the engineer instantly.• Integration means building and maintaining relations and rules
that ensures that high-level design changes propagate to lower
level, for instance the case when hull form changes are
reflected in the internal structure. In MarineSolutions, the rule
modeler and engine, conjoined with the high focus on making
the model internally consistent act together to reduce the work
associated with change management.
• Integration means that in-house or 3rd party tools may either be adapted into the user environment or allowed to access the
model to extract information needed for other tasks, or vice
versa. This may be when an ERP system requires Bills ofMaterial, or where an engineer wants access to delivery status

on components. The open architecture of the DNV MS
facilitates such mutual share of information or embedding
applications into the engineers’ user environment.
• Integration means enabling distributed engineering teams to
work on the same model. MarineSolutions makes bothconcurrent and distributed engineering a reality – not only a
vision.
An Integrated Shipbuilding Process throughout the Lifecycle
Having a true life cycle approach to engineering, the
MarineSolutions is most properly described in the context of the
different phases that it supports. Thus, the following sections
describe the virtue of the MarineSolutions in all stages of the
value chain, beginning with conceptual design and ending with
in-service operation. This places MarineSolutions in a context
recognizable by shipbuilders. The engineering life cycle isvisualized below.

Though the different design and engineering phases are
sequential at a high level, it is important to bear in mind that
they to a large extent also occur in parallel. Basic design may betaking place on outfitting while steel structural modeling may
be in the detailed design phase. And certain areas of the vessel
will be prepared for production and even being produced while
other areas still are subject to detailed design. This also
underscores the importance of the change management and
multi-disciplinary features of MarineSolutions, enabling
engineers to work in different levels of detail and have high-
level changes propagate with the need for no or minimal work
to adapt to the changes.

INTEGRATED
SHIPBUILDING PROCESS
Conceptual Design
In the conceptual design phase, the main objective is to explore,
develop and analyze alternative high-level design solutions,
often based on a request for tender, and possibly in close
collaboration with a prospective customer.The objective of the conceptualdesign phase is to explore, developand analyze alternative high-leveldesign solutions
The outcome of this phase is typically a design solution defined
by its main characteristics, a general arrangement, and a
specification document that might serve as a basis for tender
towards the customer.
Other activities in this phase include cost estimation, including
requests for prices/information, milestone planning (often
termed Master plan), and the negotiation of a Makers List
(suppliers pre-approved for delivery into the project).
In the MarineSolutions, a set of new, innovative and tightly
integrated tools are provided to support these first steps in the
ship model development. This includes tools for:
The main dimensions and formcharacteristics may besystematically investigated usingLCB/LCG diagrams, scaling thehull model directly
• Main parameters/ship technical analysis. Main dimensions,form coefficients and top-level arrangement can be
systematically varied, with instant feedback in terms of key
performance characteristics such as weights and volumes,
hydrostatics, sea-keeping, and resistance and propulsion
estimates. The designer may edit the data manually for a
single solution, or use systematic parameter variation or
optimization algorithms to explore the design space and
search for optimal solutions.
• Hull forms/lines. An initial hull form may be selected fromthe product model archive. Individual hull parts may be
replaced by parametric building blocks from the Part
Library.
• Strength/internal structure. An estimate of the mid-shipglobal bending moment, shear forces and dynamic sea
pressures can be calculated directly for each load condition.
These results will reused later in the cross section strength
analysis in the initial design phase
• Machinery. Different machinery configurations may beexplored within the constraints of class rules, the owner’s
performance criteria, trade and scatter characteristics.• Arrangement/Volumes. Buoyancy and mass distribution
diagrams (LCB/LCG) can be used to place spaces and
weights, leading to instantaneous changes in the preliminary
hull model.
• 3D visualization. To support the tendering process towardsthe customer, the preliminary ship model can be visualized
in a 3D viewer.

Initial Design
In the initial design phase, the objective is to further develop the
selected design solution from the conceptual design phase. This
comprises finalizing the definition of hull form/lines, general
arrangement, tank plan, mid-ship section design (sectionscantlings), profile & plan (deck and main bulkhead structures)
as well as verification of key performance estimates based on
ship technical analyses. Environmental impact assessment and
safety analyses may be included in the initial design phase.
The objective of the initial designphase is to fu rther, developselected design solutions from the
conceptual phase
The outcome of this phase is typically a build/contract
specification with related documentation.
A characteristic of the activities in this phase is that changes
have far-reaching consequences on both structure and systems.
Thus, the completion of initial design is a major milestone in
the entire design and engineering cycle, and changes to
decisions in this phase are increasingly more costly toimplement as the design develops.
In the MarineSolutions, the tasks in the initial design phase are
supported by a wide selection of tools. Some examples are:
• The hull form and lines are defined using either one ofseveral 3
rd party tools that are seamlessly integrated into the
solution. Alternatively, the hull may be imported using
standard file formats.
• In the surface modeling tool the main internal structure can be efficiently defined using common naval architectural
concepts, such as decks, stringers, bulkheads, etc., with all
topological relations automatically added.• Spaces and compartments can be defined by the user, or
automatically generated by the modeling tool. Weight
estimates and calculation of surface areas and COG can be
performed for the whole model and for selected areas or
blocks. The results can then be used by other tools, for
instance in the procurement of steel and paint.In the Section Scantlings tool, t hehull girder longitudinal strengthcan be verified against classsociety rules.
• The main hull structure may be verified against class societyrules using the RuleCheck package. This includes the
Sections Scantlings tool to verify the hull girder longitudinal
strength, local strength and buckling of plates.
• The key performance characteristics of the ship, such asintact and damage stability, weight, sea-keeping behavior
and resistance and propulsion, can be constantly monitored
as the design progresses to early discover breach of
constraints.
• Based on the ship model developed in the initial design phase, the necessary drawings and documentation for the
contract specification can be automatically generated using
the Ship Drawing Tool.
Basic design
In the basic design phase, the objective is to complete the
definition of hull structure, internal arrangement as well asThe objective of the basic designphase is to complete the definitionof hull st ructure, internal

system configuration and performances. The ship model is
developed to define all structural elements as well as area
arrangements (engine room, control room, accommodation,
HVAC rooms). Major pathways for ducts, channels, trays and
piping are established together with system schematics (Processand Instrumentation Diagrams, P&ID) and cabling diagrams.
Parallel to this, procurement of systems and main components,
as well as packages (like pumps, winches) takes place. The
production will regularly have started in parallel, with plate
cutting and panel assembly. Detail design will ordinarily
overlap with this phase, so that systems or areas of the ship that
have been approved by owner and class are being completed as
basic design continues on other systems or in other areas. The
production plan will typically be completed early in the basic
design phase, though typically subjected to change as the
project develops.
The MarineSolutions offers extensive support in the basic
design phase, enabling a concurrent, multi-discipline process
involving both ship model development and related technical
(analysis) and administrative tasks. Examples of tasks and tools
are:
Defining load conditions to beused in strength assessment
• In the MarineSolutions modeling environment all majorstructural elements are defined. Wizards, combined with a
structural parts library, can be applied to significantly speed
up the modeling of more complex structures, for instance of
corrugated bulkheads and hopper tank connections.
• Several outfitting tools, combined with a feature-richcomponent catalogue, can be used to efficiently insert and
position major equipment in the model, and to route cable
trays, piping and HVAC ducts. Outfitting modeling may be
done in parallel with structural modeling, logically connect-
ing components and parts belonging to different disciplines.
This ensures that change requirements from class, owner or
suppliers can be accommodated for with only minimal
rework.
The user may generate a FEAmodel directly from informationstored in the ship model
• The complete model, with contributions from all thedifferent disciplines, may continuously be monitored for
clashes & collisions, providing notifications to theappropriate user for further handling.
• In the Load Definition tool, different loading conditions may be defined, both based on applicable rules and on actual
environmental loads.
• From the structural model developed in the basic design phase, an idealized engineering model can be semi-
automatically derived, modeling the structure and applied
loads in the mid-ship section adequately for strength
analysis. Information is retained to facilitate back-stepping
to the original model. The idealized model can then be auto-
matically converted into an analysis model by discretization,
8/19/2019 Integrated CAD-CAE Solutions for Ship Design and Production(May 2004)
10/20
to be used in finite element analyses and fatigue
calculations.
• Several machinery analysis tools can be included in theMarineSolutions environment, providing design and analysis
services shaft alignment, power generation, distribution andconsumption, electrical load balances, crankshaft fatigue
calculations, gear rating and face load distribution, to
mention a few.
• In MarineSolutions, the ability to verify the design againstapplicable class society rules is inherent in many of the
tools. In addition, MarineSolutions offers a tight integration
with the DNV eApproval solution, allowing drawings and
documentations to be semi-automatically generated,
delivered and followed-up as an integrated part of the ship
modeling process.
The needs for volume material can be extracted directly fromthe model and serve as input to the material acquisition process,
such as coating area, steel, piping and bill of materials.
Detailed design
The objective of the detail design phase is to define all parts of
the vessel so that it is prepared for fabrication engineering. The
internal arrangement is completed with all components
positioned, all pipes drawn, and cable trays, ducts and channels
placed. Steel cut-outs are made, foundation drawings arecreated, and several steel structural (e.g. knee-plates, brackets,
clips) or outfitting details (pipe supports, hangers) are defined.
Local structural stiffening is defined (e.g. under foundations)
and welding or robot guidance parameters are defined to
prepare steel cutting and production information.
When the engineering has moved into the detailed design phase,
procurement of most systems will have been completed and
sections will already be erected and outfitted in areas of the
vessel where detail design (and fabrication engineering) is
completed.
In this phase the MarineSolutions is focused on speeding up themodeling process by automating labor-intensive and repetitive
tasks. This is made possible through the use of customizable
rules, combining shipbuilding knowledge and information in
the ship model to intelligently perform the detailing and work
preparation. Examples of tools and features applicable in the
detailing phase include:
• Automation of the structural detailing of profiles, placingend-cuts and determining weld details based on the
geometry of the connection
• Automatic generation of slots for profiles penetrating plate
systems, automatically generating the correct slot type based
User defined rules for automatingthe detailing are used extensivelyto offer a modeling productivityfar beyond existing solutions

on information already contained in the model, such as
profile type, compartment type, etc.
• 3D routing of pipes, HVAC and cables, automaticallyselecting connections and components based on rules and
specifications
• The penetration management functionality ensures that bothstructural and outfitting design intentions are captured in the
model.
• Steel outfitting, such as ladders, rails etc. are selected fromthe component catalogue, and logically connected to the
model. Foundations can be automatically selected when the
equipment is placed, based on information on the specific
footprint of equipment.
The slot is generated from AssemblyMethod Rules. When the profile cross-section is changed, the slot ischanged automatically
• Using the strength assessment tools, structural details may
be analyzed, reusing the results from previous ‘global’analysis. This can be used to verify the capacity of critical
“hot spots” based on experience of similar/sister vessels, or
used to evaluate alternative design solutions.
Production engineering and production
The primary objective of the production engineering phase is to
define all information necessary for production. All but some
details will be completed in the detail design phase, and the
activities typically imply either extracting information (in the
form of lists, tables and drawings) and convert the model data(structure and arrangement) into data that can be processed by
automation in the workshops. It also implies processing the
model to prepare for production, like production fairing, hull
unfolding, shrinkage and margins, and plate nesting.
The main objective of theproduction engineering phase isto define all info rmation necessaryfor production.
Typical (final) output are NC information for plate cutting,
panel robot lines, profile cutting lines, pipe cutting and bending,
and the like. It also includes detailed assembly drawings, for
instance section assembly or hull erection. Information for pipe
prefabrication (e.g. pipe spool isometrics) or steel outfitting
(e.g. foundation assembly drawings) will be completed and bills
of material will be generated. Cutting tables or tables for jig-
setup are generated.
In MarineSolutions, several tools are provided to develop the
ship model further from the detailing stage to comprise the
necessary data used by the yard’s production centers. And, as in
all other phases of the process, the manufacturing aspects of the
model are derived directly from the design model, reusing all
existing data, and maintaining all relations. This means that also
at this stage, design changes will instantly materialize into
updated manufacturing data, without having to repeat the
manufacturing engineering process.
Some of the MarineSolutions core tools in production
engineering are:
8/19/2019 Integrated CAD-CAE Solutions for Ship Design and Production(May 2004)
12/20
• Manufacturing planning: This includes functionality rangingfrom sectioning the complete ship into blocks, to the
grouping of single parts into assemblies. These activities, in
terms of sub-dividing the ship into manageable parts that can
be planned, designed, and manufactured, are undertaken atdifferent levels of detail throughout all phases of the design
and engineering process.
• Unfolding and nesting. These are typically based on yard-specific tools or algorithms. These may be 3
rd party plug-ins,
tightly integrated into the solution. Necessary model data are
automatically extracted from the ship model, and the result
of the nesting process is stored along with the model.
Changes in the corresponding assembly will automatically
trigger a new run of the unfolding and nesting algorithms.
• Configuration data for pin jig workstations can be auto-
matically generated based on information on pin positionsentered by the yard. The same applies to robotic tools for
cutting and welding.
• An array of tools is available for production preparation interms of applying fabrication and assembly margins to the
unfolded plates, and correcting for shrinkage.
• Marking on plates may be automatically generated based onthe physical connections in the ship model. Markings are
added as separate object in the product model – not only as
lines in a 2D drawing program. This means that the marking
will be updated automatically as the model changes, and
may have attributes and labels that can be automaticallyderived from the model using yard customized rules.
The generation of production drawings may be automated
combining the functionality of the Ship Drawings tools with
customizable rules, allowing drawings to be generated on an as-
needed basis.
Commissioning
In this phase the yard need to prepare all information that is to
be handed over with the ship, and to make the final verifications
that the vessel is built in accordance with the contract
specification and class and statutory rules.
The information handed over consists of ship-owners manuals,
where the ship manual is prepared by the shipyard and the
engineering manuals (including operation and maintenance
instructions) are prepared by the system or component
suppliers. Also as-built information is handed over to the
owner.
The combined concepts of a product model architecture
containing the complete ship definition, and an open technology
platform opens up for extensive reuse of data from the
newbuilding phase into operation. Examples of such
applications are:
8/19/2019 Integrated CAD-CAE Solutions for Ship Design and Production(May 2004)
13/20
• Extracting as-built documentation, such as drawings,inventory lists, systems diagrams, to the owner
• Transferring the complete ship model to the operational phase, to be used and maintained by the owner, the class
society and potentially repair yards. This is likely to becomean increasingly important issue for owners in the years to
come.
• Inventory lists and equipment data can be extracted and usedas input into the definition of the database used for onboard
planned maintenance systems
• Electronic certificates received from the class society can beretrieved and linked directly to the corresponding
system/equipment, to allow for easy transfer to, and follow-
up in, the operational phase.

APPROACHES TO
INTEROPERABILITY
In this section we highlight a set of issues relating to integration
of software applications and data models, and discuss how
MarineSolutions will address their solution.
Application Integration
MarineSolutions is a comprehensive and customizable suite of
applications, which contains Intergraph Corporations IntelliShip
(IS) and IntelliShip Foundation Software (ISF). Its rich, open
integration mechanisms offer efficient application integration,
not only within the suite itself, but also to other applications
that need to participate in the various engineering processes
throughout the project lifecycle and subsequently need to
exchange data with MarineSolutions.
Integrating two applications means that they are able to
exchange relevant information in an efficient manner.
Traditionally, applications have been integrated by “point-to-
point” integration, which means that for each pair of
applications to be integrated, a specific integration mechanism
is devised. It is clear that this approach does not scale well, and
quickly breaks down, as the number of applications to integrate
grows. Another integration approach is the shared storage
approach, i.e. several applications share the same database.
Unless the different applications are managed in tight
coordination, this integration approach also does not scale well,
because changes to the shared data model must be coordinated
across many different applications.
Thus, MarineSolutions uses a third approach that offers
efficient, but loosely coupled application integration. Thisapplication integration mechanism is based on ISF, an
application integration framework delivered by Intergraph,
which allows any application to exchange data through well-
defined XML interfaces. At the core of ISF is a data warehouse
with powerful publish/subscribe mechanisms.

ISF replaces point-to-point and centralized integration withdistributed, data-warehoused integration – the ideal
8/19/2019 Integrated CAD-CAE Solutions for Ship Design and Production(May 2004)
15/20
environment for engineering data management, management of
change, global data access, and reuse of data.
This distributed data architecture allows applications to publish,
retrieve, subscribe, unsubscribe, and compare data between the
engineering tool and the data warehouse. An application publishes its information to ISF through an application-specific
component, the ISF Adapter. The ISF Adapter transforms
application-specific information to a published XML schema
that allows other applications to request that information from
ISF and receive it in a readily accessible XML format.
Furthermore, applications are allowed to subscribe to changes
in ISF data. Hence, subscribers are notified whenever data
changes occur in the ISF.
Since ISF is based on Internet standards, such as HTTP and
XML, it allows applications to exchange data over the Internet,
which maximizes interoperability. Each application is in controlof it’s the interfaces to its published data, so no consolidation
with other applications’ interfaces is required. Any application
is able to read any published schema, so there is no need for
point-to-point integration of applications.
Integrated workflow
An important aspect of DNV MS is its ability to support
custom, best-practice engineering processes. This support
comes from the ability of the system to model and monitor the
execution of tasks in an engineering project. Furthermore,
MarineSolutions, including ISF and IS, is capable of invoking
its applications in the proper task context and with relevantdata, and take proper care of the result. This greatly reduces
overhead and increases process efficiency.
Collaborative enhancement of engineering data
ISF provides mechanisms for collaborative enhancement of data
while reducing the need for redundant input of data between
engineering tools.
The applications in the MarineSolutions suite publish data that
are identified as shared to ISF. Applications subscribing to
these data are notified of changes. Change notifications may
trigger updates of application model as well as relevant work processes.
Change Management
By providing a platform that integrates the flow of information
between applications, ISF effectively supports change
management and minimize work duplication by notifying all
interested parties of pending or proposed work.
Customization
Customizing MarineSolutions for a particular customer means
8/19/2019 Integrated CAD-CAE Solutions for Ship Design and Production(May 2004)
16/20
• Customization of processes and workflows to fit theworkflow management requirements of the customer. The
workflow between collaborating applications is managed
through ISF and configured according to each customer’s
needs.• Custom integration of applications used by the customer. A
loose integration with the framework can be done with
minimal impact to the application itself. An ISF-adapter
must be written for the application to support key
publish/subscribe functionality. A map must be defined
between the applications internal data structures and ISF
Schema.
A lifecycle oriented Product Model
The modeling philosophy in MarineSolutions borrows from
concepts and constructs from product modeling in a life-cycle perspective, as defined and developed in a series of
international standardization projects over the past years.
• The 3D-product model of the ship is built up as a continuous process through the design phases.
• The product model keeps data and information as what itrepresents, and tries to be independent of the view of the
different work process and application contexts. The view
of the applications is kept in the applications own data
structure or local data model for this specific purpose.
• The product model makes it possible to keep 3D information
and visualize 3D models from the very beginning of thedesign process.
• The product model can be mapped and related to standarddata modelling technology, such as ISO 15926 Epistle Core
Model. This will ensure that the data is kept in a way that
they can be reused by different applications using the data in
their own view.
• Information exchange and sharing should as far as possible be based on International standards as ISO 10303 Step and
ISO 15926 “Lifecycle data”.

EXAMPLE OF BENEFITS TO
SHIPBUILDERS
Approval of mid-ship section scantlings
This example of how MarineSolutions, may be used to deliver
value focuses on approval of section scantlings/mid-ship main
drawings in the initial design phase.
Today this exchange of design input and comments between
ship designers and classification society engineering typically
involves email messages and manual updates of disparate
design and analysis applications. This is a time consuming and
error prone process.
The planned approach to handle this process in MarineSolutions
will improve both he speed and quality of this exchange:
• The designer uses Nauticus 2D Section Scantlings, as part ofMarineSolutions, to produce a drawing of the mid-ship
section, defining the hull, bulkheads and stiffeners.
• The designer reads the mid-ship section-scantling into Nauticus “D modeler where it exists as a defined structural
model and can be analyzed for strength using structural
analysis functionality.
• The designer saves the then saves mid-ship drawing in IGRformat and transfers to SmartSketch.
• SmartSketch publishes the mid-ship drawing IntelliShipFoundation, to the information and document management
system in MarineSolutions, through a ISF adapter.
• DNV Exchange can retrieve the mid-ship drawing as a raster
file from IntelliShip Foundation through another ISFadapter.
• DNV Exchange transfers the mid-ship drawing to Nauticus Newbuilding (part of NPS, the Nauticus Production System).
• The approval engineer can comment and red-line the mid-ship drawing, and publishes the marked-up drawing back to
IntelliShip Foundation.
• The ship designer is notified by IntelliShip Foundation thatcomments are available from the classification society.
• Various tools in MarineSolutions for changing the section
scantling design, or calculate stability & tonnage, loading,strength and performance.

The solution outlined above is planned for completion and
release in the first part of 2004. An even more streamlined and
integrated approach, using direct exchange between the 3D
model in IntelliShip and NPS will be developed for subsequent
inclusion in MarineSolutions.
As the requi rements of theshipbuilding industry grow andchange, the suite of productscomprising the Marine Solutionwill grow and change toaccommodate them.
