                          Interoperability Problem

• Communication between diverse computer systems is a big challenge
  in today’s environment:
       – As CAD/CAE/CAM systems have proliferated in the U.S. shipyards,
         interoperability among these systems has become a major issue
       – Interoperability is an issue within a shipyard as well as between partnering yards
         and with the Customer
• This problem is further aggravated because:
       – Most recent and future ship design and build contracts involve multiple
       – Length of time to design and build a ship often exceeds the life span of current
         computer systems driving the need to move existing data to new computer
       – Requirements for life cycle support of the ship will far exceed the life span of
         current computer systems, again driving the need to move existing data to new
         computer systems

                   ISE Interoperability Solution

• The Integrated Shipbuilding Environment Consortium
  (ISEC) is attacking the interoperability problem on a broad
  front involving numerous standards, tools, and
  organizations, including:
       – STEP (Standard for Exchange of Product Model Data)
       – XML (Extensible Markup Language)
       – Website
• The ISE Projects have helped develop these standards,
  defined the approach, and implemented a solution to ensure
  information interoperability

                              ISE Project Approach
• 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
       – Enable each enterprise to use its own tool set rather than all move to the same

• Drive development of shipbuilding product data standards (e.g. STEP,
       – Construct a single Shipbuilding Information Model
       – Demonstrate and educate U.S. shipbuilding community

• 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

                    XML + STEP = Ideal Combo
          • Data is independent of IT infrastructure, but standards
            are required to reflect system needs for exchange
             Transactions of Data Packaged in Standards
                  Virtual XML = Industry Standard            Standards

                           XSLT - map data to another XML schema

                XML :                              STEP :
                • Accepted format/schema method    • Standards for data expression
                • Web-enabling                     • Standards for geometric exchange

                                  ISE Architecture

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 geometry & geometric product models
• Permissive (mediation) architecture
       – Lets each enterprise choose its own tool set
• Amenable with CAD platforms used by U.S. shipbuilders

                                        History of ISE Projects
                 • The ISEC is led by U.S. shipbuilders along with commercial
                   software vendors, and information technologists
                 • This team has been together for eight years and has
                   developed much of the infrastructure and architecture
                   necessary for shipbuilding information interoperability

                Interoperability: Current Related Efforts

• ISE-6            (Enabling Shipbuilding Interoperability)
       – Deploy information technology systems that meet the shipbuilder’s
         interoperability requirements in the area of life cycle support and post-
         delivery operations
• NPDI             (Navy Product Data Initiative)
       – To specify the requirements for and drive the implementation of product
         data systems based on an open architecture having suitable functionality
         and enterprise-wide interoperability to support affordable Navy ship
         design, construction and service life support
• SCIM             (Ship Common Information Model)
       – SCIM will codify the models developed under the ISE Project under NSRP
         over the past seven years
       – It will be a separate document from the IPDE Specification to be produced
         by the NPDI Project, but it will be referenced by that IPDE Specification
       – Initial versions of the two documents will be completed in the same
         timeframe, but updates and subsequent versions can be issued

                       ISE Interoperability Solutions

• Interoperability solutions must apply to the entire life cycle
• Initial efforts focused on Design issues
       – Focus has been on:
            • Transfer between multiple Design agents
            • Exchange between Design and Construction agents
            • Transfer of Product Models from Design agent to Customer
• Attention later focused on Manufacturing
       – Recent ISE efforts have discussed unique Manufacturing issues involved in
         transfer of Models for: Steel Processing, HVAC, and Piping
• Focus has now shifted to Life Cycle processes (such as Maintenance
  and Repair)
       – Involves different issues and requires different information

                        Issues Arising for Transfers
                           Throughout Life Cycle

• The information exchanged to support Maintenance and Repair is
  different from Design and Construction
       – As-built conditions of the ship needed
       – Changes made during ship’s service must be reflected in the product model
       – Updates to Catalogs for replacement parts must be available
• Ships have long life span (up to 50 years)
       – Ship will likely outlive CAD systems used during Design
       – Even computer hardware and storage media will not survive for life of ship
• Change management is a major cost driver throughout the life of the
  ship and should be addressed by any interoperability solution

                     improved availability, reliability,
                     maintainability, and lower cost
                     of ownership
               Exploit Investment in Product Data
                   • Users of information systems
                     want more open platforms to
                     reduce IT costs and ensure
                     longevity in use of information
                   • Digital Product Data has become
                     a valuable business asset
               For shipyards, the investment in
               Product Data has not yet been
               leveraged for life cycle support

      Enabling Shipbuilding Interoperability
       – Majority of the total cost of ownership of a Navy ship
         accrues after the ship has been delivered
       – Life cycle support; repair, maintenance and overhaul;
         ships’ operations, testing and training are all
         information intensive processes
       – The Navy has steadily moved toward more modern
         systems and technologies to cope with the burgeoning
         information needs, but technology has evolved faster
         than the deployed solutions

                                      ISE-6 Phase 2

• Phase 2 of the ISE-6 Project will run from April
  2008 through March 2009
• S1000D is an international specification for the
  procurement and production of technical
       – It is an SGML/XML standard for preparing,
         managing, and using equipment maintenance and
         operations information
• The Navy has been working toward a new-
  generation of interactive technical manuals for
  deployment on-board ship
       – There has been pressure to move to the topic-based
         approach embodied in the S1000D standard but, to
         date, this migration has been only partially
• The next phase of ISE-6 will develop use cases for
  shipboard interactive technical documents that
  take advantage of the new capabilities of the
  S1000D standard

• 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
            •   Electrical
       – Translator generators for custom representations
       – XML schema generators
            • ISO 10303-28 ed 2
       – Automated test frameworks for conformance testing

• In order to increase the availability and lower the price of
  production ready computer systems:
       – The ship owner / operator needs to insist that data be delivered in a
         system neutral format
       – The shipbuilder needs to insist that robust STEP functionality be
         an integral part of computer software products
• The next challenge is to move this demonstrated technology
  into the mainstream and insure that the technology is mature
  enough to transition into commercial CAD, CAE, CAM,
  and PDM products
• Enabling interoperability throughout the ship’s life cycle is
  a major challenge in achieving the goals of NSRP
