What is STEP? Why do we need it? Are we there yet?

The Navy and Shipbuilders Are Using Product Model Data Technology Product Model Data = 3-D CAD + object definitions + other documentation

Information Technology ages quickly… … but ships last a long time!

Shipbuilders’ 3D CAD Systems by Programby CAD System

concept design fabricate assemble test support deliver What is STEP?...an international standard (ISO 10303) for exchanging data between different systems (CAD, CAM, CAE and PDM)...a computer interpretable definition of the physical and functional characteristics of a product throughout its life cycle

Manufacturing Control Product Support Product Design STEP Enables Complete and Accurate Data Exchange and Use STEP Enables Reuse of Design, Planning and Manufacturing Data Suppliers Customers Primes Partners STEP Enables Consistent and Timely Data Sharing by Participants Engineering Analysis Manufacturing Planning

Develop and demonstrate tools that are low cost –can be selectively used by shipyards to support interoperability –capitalize on XML and related Internet technologies Flexibility is critical –allow shipyards to transform their data to/from common information model Drive development of international shipbuilding product data standards (e.g. STEP, PLIB) –Construct a single Shipbuilding Information Model –Demonstrate and educate U.S. shipbuilding community –Validate the international product data standards ISE Project Approach
