PROJECT INFORMATION OBJECTIVE

Prime/Lead: DRS Technologies - Advanced Marine Technology Center Team Members: Marinette Marine Corporation, VT Halter Marine, NASSCO, Austal USA, NAVSEA 05, Gibbs & Cox, SSIUSA, BAS Engineering Duration: 12 months

Build on previous Panel Project to continue to improve the business process of transferring data from detail design to weight engineering, to better support NAVSEA’s need for complete, accurate, and consistent data that can be used throughout the lifecycle of the ship. Enable shipyards to cost effectively update their mass properties database more frequently, providing timely insight into any developing weight and/or CG issues.

DELIVERABLES/BENEFITS/ROI FINANCIAL

• Improved weight reporting to NAVSEA
• More complete & accurate weight and CG data
• Dramatically reduce data transfer process time

Program Funds: $150K Cost Share: NA

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.

Prototype System Objectives

• 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
• ne 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

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

Data Transfer Scenarios

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

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
• ptionally remove “extraneous” data that the ShipConstructor user has drawn outside
• f the actual model
