What is STEP? What does it do?
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!
NIDDESC Navy / Industry Digital Data Exchange Standards Committee NAVSEA / U.S. Shipbuilding Industry cooperative program to improve data exchange ( ). Started from Seawolf (NNS/EB) and DDG51 (Ingalls/Bath) Data Exchange efforts. Developed IGES 3D Piping Application Protocol (Mil-D Class V) and initial U.S. STEP Shipbuilding Application Protocols for: Structure Piping HVAC Electrical cabling & wireways Outfitting & Furnishings NIDDESC STEP Application Protocols issued as NSRP “Standards” in 1995.
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
ISO STEP “Standard for the Exchange of Product Model Data” Standardized neutral format for exchanging Product Model data between dissimilar CAD/CAM, Materials management, and PDM systems. Developed in computer-processible information modeling language (EXPRESS). Broad international involvement across all major industrial sectors including Aerospace, Automotive, Shipbuilding, Process Plant, Offshore, and Building Construction. Implemented through CAD system translators to international industry-consensus STEP “Application Protocols”. Provides mechanisms for file transfer or for distributed data sharing. Related Part Library Standard (ISO 10384) for exchange of vendor and project part catalogs.

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
