MARINE ENGINEERING (Continued from page 59) information technology in order to save time and money, it is interest- ing to note that a consortium of

U.S. shipyards and CAD system developers have successfully demonstrated an exchange of ship- building data between its mem- bers. The prototype translators 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.

The consortium includes

Computervision Corp., Electric

Boat Corp., Ingalls Shipbuilding,

Intergraph Corp., Kockums

Computer Systems Inc., Newport

News Shipbuilding, The

University of Michigan, Avondale

Shipyards and Advanced

Management Catalyst Inc. (facili- tator).

National Steel and Shipbuilding

Company, participating through

Kockums Computer Systems, and the Naval Surface Warfare Center,

Carderock Division are providing additional technical support to the consortium. MariSTEP is spon- sored by the Defense Advanced

Research Projects Agency (DARPA).

In the initial implementation effort, five shipbuilding environ- ments enhanced their internal sys- tems' product model data and developed translators to support the export and import of ship- building data. In this first phase,

Intergraph Corporation, Newport

News Shipbuilding and Kockums

Computer Systems successfully exchanged ship molded 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.

Application areas and correspond- ing ISO STEP Shipbuilding

Application Protocols (APs) are

Ship Molded Forms (AP 216), Ship

Arrangements (AP 215), and Ship

Piping (AP 217).

February, 1999

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 molded forms, compartmentation, and pip- ing data.

Brass Works Relocated

Amcast Industrial Corp., a man- ufacturer of technology-intensive metal products, has purchased Lee

Brass Company. Lee Brass makes cast brass products for residential, commercial and industrial plumb- ing systems. In a related action,

Amcast has decided to phase out brass operations at Flag Brass in

Pennsylvania. The company expects the consolidation to have long-term benefits for all of its marine and other industrial cus- tomers.
