3. Ship Common Information Model
The SCIM is the…
Ship Common Information Model
…it provides
the ability to share data
for U.S. Navy ship design, analysis, construction, and post-delivery support
Narration:
The SCIM is the Ship Common Information Model.
It provides the ability to share data for U.S. Navy ship design, analysis, construction, and post-delivery logistics support
Let’s see why this ability to share data is important, both within a shipyard and across the industry…

4. Expansion of CAD/CAE/CAM Systems in U.S.
Narration:
The proliferation of Computer-aided Design, Engineering and Manufacturing Systems has drastically improved the process of designing and building Ships.
But sharing data between these different computer systems is challenging.

Narration:
In order to understand why the ability to share data is important, we need to understand what an Integrated Product Data Environment is.
An Integrated Product Data Environment, or IPDE, is a collection of business processes and computer systems which house the product model data of the ship.
IPDE’s enable people to work in concert towards the business goals of designing, building, operating, and maintaining a ship.
When a Shipyard invests in an IPDE to integrate its purchasing, design, planning, and manufacturing systems, it can realize significant efficiencies in the process of designing, building, and maintaining a ship.
With this reward come risks that must be addressed, particularly when the data must be maintained for the life of the ship.
Let’s take a look at these risks…

6. Length of time to design and build a ship often exceeds the life span of current computer systems…
Concept
Preliminary
Detail
Construction/Test
Narration:
With the rapid evolution of computer operating systems and software, the length of time it takes to design and build a ship may exceed the life span of the original computer systems and design software chosen for the ship program.
This may require that the ship design and construction product model data be moved to a later-generation IPDE during the construction of the follow-hulls in a Class.
This may require the ship design and construction product model data to be moved to a later generation IPDE during the construction of the follow hulls in a Class

7. In-service support vs. life span of computer systems
Narration:
Beyond its design and construction time, in-service support and future modification of the ship will FAR exceed the life span of the original computer system.
Though the current-generation IPDE computer systems may die in a few short years, or at most a decade, much of the design and manufacturing data contained within them must survive long into the future, some for the lifetime of the ship.

9. Virginia Class & Ohio Replacement Class Submarines
Most recent and future U.S. Navy ship design and build contracts involve multiple shipyards

Bath
DDG51 Flight II & DDG1000
Ford Class
Carrier
Newport News
Narration:
These risks and challenges are relevant in that most recent and future U.S. Navy ship design and construction contracts have involved collaboration among multiple shipyards
The latest carrier design is partnered between Newport News Shipbuilding and Electric Boat
Ingalls and Bath are working on the DDG1000 and the DDG51 Flight 2 Restart
Electric Boat & Newport News Shipbuilding have been partnering on the Virginia Class and the Ohio-Class replacement Submarines
This means that each Integrated Product Data Environment needs to communicate from the earliest stages of design, throughout the life of the ship.

10. Interoperability U.S. NAVY IPDE IPDE IPDE Narration:
The ability to “work in concert” is called “interoperability”
Interoperability can be challenging within the systems and organizations of each individual shipyard
As already mentioned, the challenge increases when there is a need to communicate between these systems and those at partnering shipyards and the Navy
IPDE

11. Collaboration is a trend that will continue
U.S. NAVY
“One Shipyard”
Narration:
Collaboration among multiple shipyards is prevalent today and this trend is going to continue
In these cases, interoperability is critical to the success of these collaborations
The Navy views interoperability as enabling multiple yards to be seen as “One Shipyard”
We will now look at the standards that allow data exchange between different computer systems and software…

12. A Standard is required for this exchange of product data
So, why not use the STEP ISO Standard directly ?
ISO is the international standard
Informally known as “STEP ”:
(STandard for The Exchange of Product Model Data)
Narration:
ISO is an international ISO standard for the exchange of product design, manufacturing, and through life support information
It is informally known as "STEP", which stands for "Standard for the Exchange of Product model data”
STEP’s objective is to provide a mechanism that is capable of describing product data throughout the life cycle of a product, independent of any particular computer system
So, why don’t we use the STEP ISO Standard directly instead of using the SCIM, the Ship Common Information Model?

13. The STEP Series of ISO Standards support many industries
The STEP series of ISO Standards were developed by and support many industries in addition to shipbuilding, such as aerospace, automotive, and process plant design and construction
Translators must be developed using these standards so that data can be exchanged
These translators for data exchange have not been developed for all of these industries…particularly for the shipbuilding industry…
Aerospace
Automotive
Shipbuilding
Plant Design

14. The STEP Standards require Translators
Shipyard A
The STEP Standards require Translators to share the data between different systems and between shipyards
Developing the translators requires specialized knowledge and special software tool kits, making them expensive to implement
Shipyard B
Shipyard C
Require Special TOOL KITS
Are EXPENSIVE

15. Here are your STEP-Translators
The limited market of Shipbuilding has not encouraged commercial CAD vendors to develop ship-specific translators
Here are your STEP-Translators
What about us?
Aerospace
While many current CAD systems have STEP geometry translators that can be used by any industry,
the limited market of shipbuilding and repair has discouraged the commercial Cad vendors from developing the ship-specific translators that our industry needs.
Let’s see how the SCIM makes it possible for the shipyards and the Navy to solve our data-sharing challenges …

Narration:
The SCIM is structured to use the STEP geometry translators from the CAD vendors together with shipyard-developed XML translators
This allows the geometry of the CAD Vendor software to be related to the non-graphical shipbuilding information from CAD, CAM, PDM, ERP, and Logistics systems.

Narration:
The Product Data needs to be captured as it transitions throughout the Life Cycle of the ship.
The Product Data is spread across many computer systems and specialized software packages
The SCIM, the Ship Common Information Model, facilitates the sharing of this Product Data between the pieces of an IPDE and with external systems such as collaborating shipyards and the Navy.
It can also be used as a method for long term archiving of the ship design product data that may need to be retrieved at any point in the future.

20. No need to rely exclusively on CAD Vendors for all Data Translator Support
XML is standard method for accessing non-graphical data
SCIM Documented in XML
Narration:
XML has become the standard method for accessing non-graphical data in software systems.
Documenting the SCIM in XML, using shipbuilding terminology, allows shipyard IT personnel to develop the IPDE data translators in-house, with or without support from their CAD vendors.
This allows for development of IPDE Data Translators In-House

Narration:
Hopefully, by now, you see the importance of the Ship Common Information Model
It allows shipyards to move data between the different pieces of their Integrated Product Data Environments.
It allows shipyards to exchange data with each other and with the Navy.
This is 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.
To conclude, let’s go over the advantages to implementing the SCIM at your shipyard…

25. 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
