A consortium of U.S. Shipyards and Computer-Aided-Design (CAD) Systems developers recent- ly demonstrated the exchange of shipbuilding data between its members. The prototype transla- tors were based upon the STEP (Standard for the Exchange of

Product model data) standards for the shipbuilding industry being developed within ISO. These translators are designed to enable shipyards and ship design compa- nies to exchange detailed ship design information between dis- similar design systems, a process reportedly not possible using pre- vious technology.

The consortium includes

Computervision Corp., Electric

Boat Corp., Ingalls Shipbuilding division of Litton Industries,

Intergraph Corp., Kockums

Computer Systems Inc., Newport

News Shipbuilding (NNS), The

University of Michigan, Avondale

Shipyards and Advanced

Management Catalyst Inc. (facili- tator).

National Steel and Shipbuilding

Company, participating through

Kockums Computer Systems (KCS), and the Naval Surface

Warfare Center, Carderock

Division are providing additional technical support to the consor- tium. MariSTEP is sponsored by the Defense Advanced Research

Projects Agency (DARPA).

In the first phase, Intergraph,

NNS and KCS successfully exchanged ship moulded forms and compartmentation data.

Intergraph based its translation on its ISDP system, Newport

News, its VIVID system, and

Kockums, its TRIBON system.

Electric Boat (EB) and the team of Ingalls Shipbuilding and

Computervision (CV) exchanged ship piping, with EB using its

Catia based system, and with the

Ingalls and CV team using PTC's

Dimension III product.

In the next phase of the project, the teams will switch implementa- tion targets so that by the end of 1998, all five shipbuilding environ- ments will have compatible trans- lators for exchanging ship mould- ed forms, compartmentation, and piping data.

In addition, all five teams will complete translators for the exchange of ship structures (AP 218) by summer of 1999.

A Commitment To Technology

U.S. ship and boatbuilders have been on a buying spree of sorts, purchasing the latest hardware and software technology which is designed to make the building process more time and cost effec- tive. Spurred by a declining U.S.

Navy order log, builders were forced to upgrade to survive.

The latest show of technological might comes in the form of

CAD/CAM development, as a con- sortium of builders and suppliers have embarked on a journey to improve the data exchange between the various programs. (For the final part of a four-series article on how a U.S.-led team has used the latest tools to develop more efficient engine room
