CAD/CAM committed stakeholders — an empow- ered team with representatives from

U.S. shipyards, CAD/CAM vendors, regulatory bodies and software vendors.

The team has developed and approved an architecture for interoperability that includes agreement on information requirements and data exchange stan- dards and protocols. The ISE architec- ture uses readily available Internet tech- nologies as well as data exchange stan- dards being developed in conjunction with the International Standards Organi- zation (ISO).

Progress, Implementations and Early

Results

Shipyards are already using ISE tools in warship production on the submarine and Carrier programs. These tools enable shipyards to select digital tools (simulation, analysis, ERP, CAD, PDM. etc.) best suited to their business, yet fully participate in co-design and co- production arrangements that rely on other information systems to design, build and maintain war ships. High- lights of the project's on-budget, on- schedule successes include: • Development/agreement of indus- try-wide interoperability architecture • Publication of hundreds of use cases defining requirements for infor- mation sharing at many shipyards • Development of common data ele- ment definitions and common taxonomy for transferring data between parts libraries and supplier catalogs • Development, demonstration and distribution of tool sets for inter-organi- zational sharing of piping system infor- mation. including: parts catalog infor- mation, system diagrams and simulation engines, and detailed design and analy- sis systems. Available, proven tools are a mix of open source software available on the project's website and commer- cially available tools in the product lines of collaborative design, co-production, integrated supply chain, and standard- ized parts.

The project recently completed the second of three years with a highly suc- cessful demonstration of capabilities.

The April 4 demonstration showcased the impressive "eShipDesign" capabili- ties of the consensus architecture, stan- dards, protocols, and toolsets developed to date. The following capabilities were demonstrated: • Direct download of piping and structural parts data from vendor elec- tronic catalogs into shipyard digital parts libraries. • Export of detailed CAD data to analysis tools, such as Anteon's Proteus

Flagship Suite, simulation programs such as SIMSMART. and ship classifi- cation software such as the ABS Safe

Hull program. • Successful electronic exchange of molded form data (complex geometric

July, 2002 shapes of steel hull plating) between four different CAD systems (Dassault's

CATIA, Sener's FORAN, KCS' TRI-

BON and Intergraph's GSCAD).

Examples of estimated savings are:

Cost to link two IPDE (Integrated

Product Development Environment) systems for co-design or co-production is estimated to be $30 million. If there are three programs over the next 10 years that use an IPDE, the total cost would be $90 million. It has been esti- mated that the ISE developed tools will save 40 percent or $36 million. • A top down projection of savings for the design process for Navy pro- grams is $188 million over 10 years (see chart, previous page).
