Advanced Marine Technology Center NSRP Business Processes Panel Project Update Leveraging Detail Design Data in Weight Engineering Phase 2 December 9, 2015 NSRP All Panel Meeting San Diego, CA This document does not contained controlled technical data/technology. 1 1

PROJECT INFORMATION OBJECTIVE Prime/Lead: DRS Technologies - Advanced Build on previous Panel Project to continue to improve the business process of transferring data Marine Technology Center from detail design to weight engineering, to better support NAVSEA’s need for complete, Team Members: Marinette Marine accurate, and consistent data that can be used Corporation, VT Halter Marine, NASSCO, throughout the lifecycle of the ship. Enable Austal USA, NAVSEA 05, Gibbs & Cox, shipyards to cost effectively update their mass SSIUSA, BAS Engineering properties database more frequently, providing timely insight into any developing weight and/or Duration: 12 months CG issues. DELIVERABLES/BENEFITS/ROI FINANCIAL • Improved weight reporting to NAVSEA Program Funds: $150K • More complete & accurate weight and CG data Cost Share: NA • Dramatically reduce data transfer process time 2 2

Follow-On to 2012 Project  Project focused on efficient use of detail design data as input to weight engineering in the shipyards by: Identifying common information with their 3D  product modeling system of choice and their weight engineering system (information alignment map) Looking for opportunities to eliminate duplicate  data entry Assessing methods for data transfer that will  provide more accurate and timely information  Developed an interface strategy and prototype software application to capture potential data exchange between the two software tools. 3 3

Prototype System Objectives Fulcrum3D Detail Design Model Weight Engineering Model • Improve the flow of information between the detail design model and weight engineering model • Maintain accuracy of the detail design and weight engineering models • Minimize the need to assign part attribution in more than one place and more than one time • Maintain the flexibility to assign SWBS group attribution in either model • Create a system design that is agnostic in regard to specific detail design and weight engineering tools 4 4

How is this different than using a spreadsheet? • Maintains synchronization of model data (added, updated, and deleted parts) • “Smart” transfer; part information isn’t lost when the weight db is updated • Handles assemblies; allows for definition of groups • Can exclude data outside the physical boundaries of the ship • Easy filtering and sorting • Easy to change unit systems 5 5

Data Transfer Scenarios XML File 1 Parts Deleted Items Weight Engineering Detail Design Fulcrum3D Data Filter Database Database (ShipWeight ) (ShipConstructor) XML File 2 Parts Deleted Items Data Filter Scenarios 1. Transfer all parts from Detail Design Model (DDM) to Weight Engineering Model (WEM) 2. Transfer subset of parts from DDM to WEM using a data filter Sub-cases a. New weight items are added to the WEM independent of data transfer b. Invalid SWBS attribution is assigned in DDM c. Changes to SWBS attribution are applied to both models in between data transfers d. Model changes are made in the DDM so that part(s) no longer meet data filter from a prior transfer e. Overlapping data filter applied with DDM changes in between transfers 6 6

System Workflow (Phase 1) Detail Design Database (ShipConstructor) Fulcrum3D Open project in ShipConstructor database Save named Define data Select saved data filter set extraction filters extraction filter Extract specified Extract added, deleted, weight data revised weight data Weight Weight Data Export weight data Neutral File Engineering to neutral file Database (ShipWeight) 7 7

2012 Project Conclusions Further development could bring more savings:  • Implement a “cross reference dictionary” in Fulcrum3D, to automatically translate ShipConstructor part descriptions into descriptions that are meaningful to the Navy customer • Convert unit weights from volume and weight per unit volume to appropriate area, thickness, and weight per unit area • Use Fulcrum to group together like items (tripping brackets) or assemblies (inclined ladders) • Interface with ShipConstructor via the Enterprise Platform, rather than using SQL statements. Test interface with other detail design systems. • Implement user-defined systems of units for display of filtered data in the Fulcrum3D interface • Use the ship extents (length, beam, depth) from the ShipConstructor model to optionally remove “extraneous” data that the ShipConstructor user has drawn outside of the actual model 8 8 8

System Workflow (Phase 1) Detail Design Database (ShipConstructor) Open project in Fulcrum3D ShipConstructor database Save named Define data Select saved data filter set filters filter Extract specified Extract added, deleted, weight data Revised weight data Weight Weight data Export weight data Engineering neutral file to neutral file Database (ShipWeight) 9 9

New System Workflow (Phase 2) Detail Design Database Neutral Part file (any) Fulcrum3D Open neutral file Save named Define data filters Select saved data filter set & boundaries filter & boundaries Filter specified Filter added, deleted, weight data Revised weight data Weight Weight data Process data Export weight data Engineering neutral file (groups, assemblies, etc.) to neutral file Database (any) 10 10

Demonstration Fulcrum3D • Reading a TSV file, filtering, grouping, sorting, exporting 11 11

Demonstration Weight Engineering Tool (ShipWeight in this case) • Importing an XML file, inserting, updating, deleting parts • Viewing groups and assemblies • Reporting 12 12
