Need for Interoperability 3/15/2018 5
Levels of Interoperability Inter-business system domain Shipyard A Shipyard B ERP/CAM Intercomponent PDM/CAD Inter-System Parts Library IDE INTOP IDE 6
Co-design Co-production * Web-based system diagrams * Web-based interop with simulation & analysis Logistics Information Support * Web access to as-planned & design product model * Web-based product model sharing * Browser access to product related documents ISE Integrated Shipbuilding Environment Maritime Supply Chain * Web-based supplier catalogs * Shared parts library Integrated Development Environment * Collaboration best practices * Shipbuilding enterprise components 7
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” 8
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 9
Overview of STEP (ISO 10303 - 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 10
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 11
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 12
XML and STEP Transactions of Data Packaged in Standards XSLT - map data to another XML schema Virtual Ship part(s) Company A Standards XML = Industry Standard Container for Data STEP = ISO Standard Language for Data* Company B Data XML (good for CAE applications) & it brings: • Accepted format/schema method STEP (good common language for CAD Product Models) & it brings: • Web-enabling • Standards for data expression • Standards for geometric exchange 13

STEP, PLIB) • Construct a single Shipbuilding Information Model • Demonstrate and educate U. S. shipbuilding community 33
ISE architecture represents an innovative, practical solution to the information interoperability challenge § Accessible to large and small shipyards • Only system dependency is Web infrastructure • Utilizes open standards § Innovative integration of STEP and XML technologies • Supports sharing of geometric & geometric product models § Permissive (mediation) architecture • Lets each enterprise choose its own tool set § Incorporated into CAD platforms used by U. S. shipbuilders 34

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 AP 216 testing 61
Summary 3/15/2018 62
ISE Tools § Tools developed by the ISE Project are made available on the Web at: www. isetools. org § These include: • Formal information requirements published – – Ship Piping Ship Structures Ship HVAC CPC Interfaces • Translator generators for custom representations • XML schema generators – ISO 10303 -28 ed 2 • Automated test frameworks for conformance testing 63
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 • www. isetools. org 64
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. § ISE 4 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 65
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 • www. isetools. org 66
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 10303 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 67
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 68
