Paul J. Rakow Naval Surface Warfare Center Carderock Division TWR-49: Long Term Retention of Product Model Data
Agenda Project Description Project accomplishments 2009-2011 Objectives Group Discussion Close-out
Why product model information? • As DOD acquisition contracts transition from electronic drawing based archive data sets to digital product model data, the respective agencies need to ensure that future users have access to the required data to support the lifecycle of their weapon system. • This includes the requirements and issues involved with the: • Transition to 3-D geometry in numerous forms and quantities. • Aggregation of product models and related data from individual components to complete weapons systems • Long-term accessibility and interpretability of the archived digital data by future generations.
Origination of the data The design spiral is actually a convoluted path Shipbuilder involvement Concept Design & Construction Core data Commissioning Evaluations & applications of core data 30-70 years In-service Retirement
What types of data? Long Term Data Retention of Weapon System • 3-D Geometry • engineering properties • associative relations • analysis data • process definition • logistics definition • manufacturing data • work breakdown structure • product structure • links to M&S • links to documentation • drawings • models • photographs • manuals
Product model data: Multiple data types Piping Images 2D Drawings
Product model data: Multiple data types Piping 3D model
What will we do with it? Research and evaluate through objective measurement, issues related to long-term data retention of large amounts of structured weapons system product data in native and neutral formats.
Stakeholders Primary Interest • National Archives and Records Administration(NARA) R&D - Long Term Knowledge retention of product model data for historical data retrieval and governmental reconstitution • JEDMICS / NESDR Storage and retrieval of engineering drawings and product model data • Defense Logistics Agency (DLA) Use of product model data for weapons system support • NAVSEA use of product model data for ships and ships systems evaluation and support
Navy Uses for Long Term Retention of Data • New Ship Designs Even when revolutionary, large portions are based upon extension of existing designs • In-service Operational and Logistical support • Repairs USS Cole, USS Intrepid, USS New Orleans and SSN Hartford, etc • Decommissioning: Identification of hazardous materials if scrapped, Live Fire Test & Evaluation (LFT & E) analysis and documentation, National Defense Reserve Fleet
Use Cases Assist in the definition of data requirements
Why the TWR 841? This ship was selected for our project because it is in-service, has a complete set of drawings available for distribution, and is: Approved for Public Release: Distribution Unlimited. This ship is used to assist in sonar tests & locate and retrieve torpedoes and missile drones.

Speed Power 1140 shp at 1800 rpm. Crew 18 Engines Two (2) Caterpillar Model 3512 V12 Construction Welded steel construction with plates welded over transverse and longitudinal bulkheads and transverse frames Propellers Two (2) manganese bronze, 54 in diameter, 46.8 in pitch, 4 blade What is the TWR 841? Torpedo Weapons Retriever Characteristics 120 Foot Torpedo Weapons Retriever The Torpedo Weapons Retriever is utilized in support of underwater acoustic submarine operations and torpedo exercises. It is designed to launch and retrieve acoustic devices as well as retrieve missiles and torpedoes in the ocean. The TWR 841 is based out of the Naval Undersea Warfare Center located in Newport Rhode Island.

Modeling Tool ShipConstructor ShipConstructor was selected as our product modeling tool as it is relevant to NARA, NAVAIR and DLA because it is AutoCAD based. It is also relevant to NAVSEA due to the following shipbuilding projects. • Deepwater – National Security Cutter (NGSS Avondale) • LCS – both variants (Gibbs & Cox on Lockheed Martin program, Austal on General Dynamics program) • CVN – 21 deckhouse (NGSS Avondale for Newport News) • ONR E-Craft (Guido Perla for Alaska Ship & Drydock) • ONR X-Craft (Sea Fighter) – Nichols Brothers
SoldiWorks was chosen due to current Navy Ship Design program usage • Rhinoceros CAD: Used for Hullform, molded surfaces, compartmentation, HVAC. • LEAPS (Leading Edge Architecture for Prototyping Systems). Secondary Modeling Tools Tool Selection
