Presentation Agenda • Interoperability Demo Scenario • Ship Arrangements Exchanges using AP 215 and AP 216 – – – Initial Design in TRIBON Transfer from TRIBON to LEAPS Modifications in FORAN Transfer from FORAN to LEAPS (and ISDP) Transfer from ISDP to Intelliship • Electrical Demonstration using AP 212 • Engineering Analysis Exchanges using AP 218 and AP 209 • Steel Processing Exchanges using AP 218 27 Apr ‘ 06 3
Interoperability Demo Scenario • During the demonstrations you are about to witness, we will be exchanging product model data from several disciplines between multiple computer systems • The scenarios are not necessarily meant to be realistic, but more to convey the types of exchanges and requirements that can be satisfied by the tools developed in the ISE Project • Data to be exchanged will include product model data used for Ship Arrangements, Electrical, Engineering Analysis, and Steel Processing • The data will be representative of product models that could be exchanged at any phase of the Life Cycle, from Concept Design through Detail Design through Manufacturing, or continuing through Repair and Overhaul 27 Apr ‘ 06 4
Description of Exchange Scenarios • The models exchanged represent the TWR 841 – Torpedo Weapons Retriever ship with data “Approved for Public Release – Distribution Unlimited” – Product Models will capture TWR Compartmentation and details of the TWR Engine Room – These transfers simulate a situation where STEP is in place to enable Shipyards to interoperate smoothly • Ship Arrangements exchanges represent – Exchanges to go from Concept Design to Detail Design at two different Shipyards – Models developed will be analyzed by Customer and changes will be suggested – Partnering Shipyards will complete the Design and feed data to other applications for analysis, manufacturing, repair, and lifecycle support • Electrical Analysis is done on TWR systems during Preliminary Design • New requirements (such as a request from an outside agency, e. g. Homeland Security) can necessitate model transfer to additional software packages for Engineering Analysis • Steel Processing scenario shows how design data for a plate can be modified in STEP before being sent to two possible construction yards with different requirements (NGSS and EB) 27 Apr ‘ 06 5

Different Representations for Data • Part 21 vs. Part 28 – Part 21 is the traditional STEP physical file format – Part 28 is an XML representation of STEP data • ARM vs. AIM – ARM (Application Reference Model) objects are in application area terminology • e. g. “Ship” or “Plate” – AIM (Application Interpreted Model) objects are in generic terminology • e. g. “Product” or “Product Representation” • ISE Project is developing mediation tools to enable a sender and receiver to communicate successfully no matter which format they select for their particular data representations – The ensuing Demos will involve the transfer of models using both of these formats 27 Apr ‘ 06 8

As-Is Process – Tribon Translator Initial Design Integration Options: Currently Available Vendor Lock-in § Ship designers and builders stay with one vendor to be able to transfer data between various design and manufacturing software packages System-to-System Bridges § Custom software can be created to link two software packages § These solutions are fragile, as they must be updated with every version change in either software package § Usefulness is limited to the two systems connected Manual Reentry § Ship designers and builders can manually reenter data in a second system § This process is expensive, labor-intensive, and error prone 27 Apr ‘ 06 15
ISE Process – Tribon Translator Initial Design Integration Options: With STEP and ISE Translators No Vendor Lock-in § Using STEP standards and translators ship designers and shipbuilders can move data between software packages provided by different vendors No System-to-System Links § Using STEP standards and translators there is no need to build system-tosystem bridge software. § A translator bridges each software package to the standard § All software systems bridged to the standard are interoperable No Manual Reentry § With automated transfers via the standard, manual reentry can be avoided 27 Apr ‘ 06 16

Engineering Analysis Task Focus and Outline: • Multiple ISO STEP Application Protocols (APs) – Primarily AP 218 and AP 209 • Different file exchange formats – Traditional STEP Express and XML forms • Leverage existing CAE software Demonstrations: • Demo 1 - Accommodating different formats – Both Part 21 (Express) and Part 28 Ed. 2 (XML) – Using mediation (XSLT transformation) • Demo 2 - Using parametric geometry L 27 Apr ‘ 06 – AP 218 ‘Implicit’ and ‘Explicit’ Geometry – Creating explicit from implicit 45
Engineering Analysis Task Goals and Objectives: • Extend interoperability capabilities by employing both the newer shipbuilding APs and the other existing ISO STEP 10303 standards. • Build on work accomplished under previous ISE projects and related efforts. • Illustrate flexible use of both STEP Express and XML formats for exchange and mediation. • Demonstrate TWR structural model exchange from AP 218 to AP 209 for use with various engineering finite element analysis software packages • Leverage these methodologies for both future Product Lifecycle Management (PLM) and Long Term Data L Retention (LTDR) efforts. 27 Apr ‘ 06 46
Extend ISO 10303 Interoperability R 27 Apr ‘ 06 47
Engineering Analysis Approach • The utility of the ISO STEP 10303 -209 (AP 209) for supporting interoperability and collaborative design (combining design geometry with detailed finite element analysis) has already been demonstrated in other venues (e. g. PDES). • All of that collaboration has been based upon exchange of traditional STEP files encoded in Express (Part 21). • In this ISE-4 task we demonstrate extensions to that approach by integrating with STEP application protocols for ship structure (primarily AP 218), and by employing more flexible collaboration and exchange scenarios using XML (Part 28) encoded files.

Multiple APs How can that work? • Different ISO STEP Application Protocols have differing file content. – AP 218 (Ship Structures) vs. AP 209 (Composite and Metallic Structural Design & Analysis). • Several ship CAD vendors have selected XML (Part 28) format for data exchange. • Other CAx (CAD and CAE) vendors employ existing (older) ISO STEP exchange files in Express (Part 21) format. • AP 203 (IS, 1994) has had more than a decade of usage. Along with AP 214, they are the most commonly used APs. They are pervasively used for CAD geometry exchange in various industries today. L 27 Apr ‘ 06 56

S. shipyards and work with currently available CAD tools – Published Implementors Agreements to enable others to use these tools effectively – Registered ISE Schemas with the DONXML Repository – Identified proposed changes/corrections to ISO STEP Standards – Created a Website to contain the relevant software tools, schemas, etc. as provided by the ISE Project • www. isetools. org – JEN-X Mediator from EXPRESS to XML will be publicly available on Sourceforge and PDES, Inc. Websites 27 Apr ‘ 06 96
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 Ship Arrangements Electrical Engineering Analysis Steel Processing ISE 2 ISE 3 ISE 4 • 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 27 Apr ‘ 06 97
Continuing Efforts • An ISE 4 Follow-On Project was awarded for 2006: – Electrical: Finish task including addition of 3 D information – Program Management: Continue support and involvement of ISO and DONXML activities • An ISE Systems Technology Panel Project was awarded for 2006: – Steel Processing: Continue efforts with emphasis on STEP-NC • Future Projects: Complete the Information Interoperability Roadmap – Goal is to turn all boxes “Blue” – ISE Project is providing tools to turn boxes from “Red” to “Yellow” and then to “Green” – Customer must invoke Requirements on Contracts in order to get these tools Implemented in Production 27 Apr ‘ 06 98
Information Interoperability Roadmap Note: Circled boxes have been addressed under the ISE Project 27 Apr ‘ 06 99
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 and XML technology • The APs that enable these exchanges have completed their development and approval as International Standards • The primary focus has shifted to testing and validating their implementations ISE Tools Enable Interoperability between Shipyards 27 Apr ‘ 06 100 and Reduce the Life Cycle Cost of Ships
Challenges • Two major challenges lie ahead of us: – Commercialization of this technology – Continuing to prototype standards based data exchange in other application areas • 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 computer software products • The next challenge is to move this technology into the mainstream and insure that the technology is mature enough to transition into commercial CAD, CAE, CAM, and PDM products 27 Apr ‘ 06 101
Summary • Enabling interoperability is a major challenge in achieving the goals of NSRP • Achieving these goals will have a major impact on reducing the cost of ships • The ISE Project is attacking these problems in many different disciplines and environments • Although ISE has been very successful, much work remains to achieve our goals 27 Apr ‘ 06 102
