4 Background and History

5 Need for Interoperability

6 Levels of Interoperability INTOP Inter-business system domain Shipyard A Shipyard B Inter-System Inter- component IDE Parts Library PDM/CAD ERP/CAM Inter-System Inter- component IDE Parts Library PDM/CAD ERP/CAM

7 7 Co-design Co-production Maritime Supply Chain Logistics Information Support Integrated Development Environment * Web-based supplier catalogs * Shared parts library * Web access to as-planned & design product model * Web-based system diagrams * Web-based interop with simulation & analysis * Web-based product model sharing * Browser access to product related documents * Collaboration best practices * Shipbuilding enterprise components ISE Integrated Shipbuilding Environment

8 Collaboration among Shipyards is Required in Today’s Environment  Almost every major recent U.S. Navy ship design and/or construction contract has involved collaboration among multiple shipyards For example: –CVNX (NGNN & EB) –DDX (NGSS - Ingalls & Bath) –Initial LPD Award (NGSS - Avondale & Bath) –VIRGINIA (EB & NGNN)  This trend will continue  Navy views system interoperability as enabling multiple yards to be viewed as “One Shipyard”

9 Goals of Integration  Better analysis through simulation  Re-use of data instead of redundant data increased accuracy eliminates unnecessary checking speed of data entry (already entered)  Facilitates partnering with other firms  Reduce overhead costs

10 Overview of STEP STEP (ISO Industrial automation systems and integration - Product data representation and exchange)  International Standard for the computer-interpretable representation and exchange of product data  The objective is to provide a mechanism that is capable of describing product data throughout the life cycle of a product, independent of any particular system  The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving

11 XML- Extensible Markup Language  Traditional STEP transfers have been via STEP Physical File exchange as defined by Part 21  To take advantage of Web technology, Part 28 is under development to standardize STEP transfers using XML  ISE Project is implementing its transfers using XML as well as permitting Part 21 file exchanges

12 XML Goal and Mission  Goal Use XML Schema to represent as much of EXPRESS semantics as possible so that XML Schema can be used to: –Document the information model –Provide delegated validation services –Support the XML instance formats standardized in Part 28  Part 28 Mission Use XML to publish STEP EXPRESS Schemas Use XML as a STEP implementation method

13 XML = Industry Standard Container for Data STEP = ISO Standard Language for Data* Data Company A Standards Virtual Ship part(s) Company B Transactions of Data Packaged in Standards XSLT - map data to another XML schema XML and STEP XML (good for CAE applications) & it brings: Accepted format/schema method Web-enabling STEP (good common language for CAD Product Models) & it brings: Standards for data expression Standards for geometric exchange

14 Development of STEP and XML for Shipbuilding

61 STEP Shipbuilding Implementation Forum  A Testing Forum for the STEP Shipbuilding APs has been established  It is being run under the auspices of the NSRP Systems Technology Panel  It will test and validate implementations of the STEP Shipbuilding APs  Forum began in 2004 with AP216 testing

62 Summary

63 ISE Tools  Tools developed by the ISE Project are made available on the Web at:  These include: Formal information requirements published –Ship Piping –Ship Structures –Ship HVAC –CPC Interfaces Translator generators for custom representations XML schema generators –ISO ed 2 Automated test frameworks for conformance testing

64 Implement in Production  The goal of current and future efforts is to make these techniques and tools available in production and to all U.S. shipyards STEP Shipbuilding Translators XML Tools Common Parts Catalog Interfaces  A Website is being established to contain the relevant software tools, schemas, etc. as provided by the ISE Project

65 Summary  ISE 1,2 & 3 has successfully demonstrated the potential of standards based data exchange to LEAN design and construction processes for HVAC, molded forms, structures and piping.  ISE4 is looking at Electrical, Ship Arrangements, Steel Processing, Analysis  Two major challenges lie ahead of us: Commercialization of this technology Continuing to prototype standards based data exchange in other application areas such as system engineering

66 Goal : Implement in Production  The ISE Project has developed tools and demonstrated interoperability between shipyards in the areas of: Structure Piping HVAC Common Parts Catalog Interfaces  The goal of current and future efforts is to make these techniques and tools available in production and to all U.S. shipyards STEP Shipbuilding Translators XML Tools Common Parts Catalog Interfaces  A Website has been established to contain the relevant software tools, schemas, etc. as provided by the ISE Project

67 Conclusions  These testing, modeling, and simulation efforts are part of an attempt to develop a suite of product model data exchange tools that will enable U.S. Shipyards to become more productive  These efforts revolve around implementation of the ISO STEP Shipbuilding standards  The APs that enable these exchanges have completed their development and approval as International Standards  The focus is now shifting to testing and validating their implementations

68 Conclusions (cont’d)  In order to increase the availability and lower the price of production ready tools: The ship owner / operator needs to insist that data be delivered in a system neutral format The shipbuilder needs to insist that STEP functionality be an integral part of product  The next challenge is to move this technology into the mainstream and that the technology is mature enough to transition into commercial CAD and Product Modeling products
