Purpose of this presentation:

What an IPDE is and why the sharing of data is important

An overview of the SCIM and how it can be used within an IPDE

The ability of the SCIM to allow the sharing of data between organizations

Factors affecting the implementation of the SCIM


…it provides the ability to share data

for U.S. Navy ship design, analysis, construction, and post-delivery support

The SCIM is the…

Collaboration is a trend that will continue

“One Shipyard”

A Standard is required for this exchange of product data

• ISO 10303 is the international standard

• Informally known as “STEP ”:

(STandard for The Exchange of Product Model Data)

So, why not use the STEP ISO Standard directly ?


The STEP Series of ISO Standards support many industries

The STEP Standards require Translators

The limited market of Shipbuilding has not encouraged commercial CAD vendors to develop ship-specific translators

What about us?


The SCIM provides a blueprint for shipyard IT personnel to develop translators

Translators


• The SCIM is based on shipbuilding portions of the Step Standards

• The SCIM defines the requirements and XML data model for Ship data exchange

• This XML Data defines the minimum set of entities & attributes that must be available for applications supported by an IPDE…

• …and for sharing with business partners and the Navy

The SCIM satisfies the STEP Requirements

No need to rely exclusively on CAD Vendors for all Data Translator Support


• SCIM Documented in XML

• This allows for development of IPDE Data Translators In-House

• XML is standard method for accessing non-graphical data


The SCIM specification is…

Fully documented and user-friendly

Usable by shipyard personnel, including non-IT specialists

Capable of validation

Suitable for contractual specification

Of practical use for agreements between shipbuilder and CAD System vendors

SCIM Chapters:

Shipbuilding Functional Areas:

• Each SCIM Chapter supports one of these functional areas

• Each of these SCIM Chapters has a corresponding XML Schema


Importance of the Ship Common Information Model

Allows shipyards to move data between different pieces of their Integrated Product Data Environments (IPDE)

Allows shipyards to exchange data with each other and the Navy

Necessary due to the Navy’s practice of requiring multiple-shipyard design and build contracts, and…

… because of the short lifespan of computer systems and software compared to the life of a ship


Advantages to implementing SCIM at YOUR Shipyard

Uses inexpensive or free XML tools rather than expensive STEP EXPRESS language toolkits

Uses existing XML application programming interfaces to shipyard PDM and CAD tools

Minimal introductory training needed for shipyard IT personnel to quickly implement XML-based translators
