Weight Engineering Tool
for Ship & Offshore Constructions
BAS Engineering, Norway
ShipWeight in a nutshell
 software tool for weight & cg estimation and monitoring, from early concept
design through detailed engineering and construction
 Ships, plaforms, semisubs
ShipWeight & ShipConstructor
 SW Weights
 SC Weights
 Analogies: IT + industry environment, sql relational database architecture,
throughout the life cycle, SWBS / PH, top down and detailed model
 Synergy: cross-validation, uses documented CAD weights, user defined
reports, user defined weight groups and weight items
 SW + SC weights crosscheck & combine for a more complete picture
ShipWeight / BAS Engineering
 More than 15 years of weight
engineering in the ship and oil
offshore industry

Bassøe Technology, Sweden

Meccano Engineering, Italy

Rolls-Royce Marine, Norway
 In use at shipyards, designers
and navies all over the world for
a large variety of vessels,
including navy vessels (aircraft
carriers, submarines,
destroyers, etc), offshore
vessels (FPSOs, Semisubmersibles, etc) to
commercial ships (tankers,
cruise and fishing vessels, etc)

ShipWeight: UBVs, analogies, synergies

ShipWeight provides Weight & CG control tools:
 Unique, early stage, parametric estimation tools for weight and CG (ShipConstructor
analogy: repeatable, representative, unique model portions)
 Historical data regression (ShipConstructor analogy: multiple database templates)
 Standard and user-defined parametric formulas and coefficients (ShipConstructor
analogy: custom stock libraries and associations)
 Real time Weight & CG tracking & calculation throughout design & construction,
custom reports using Crystal Reports (ShipConstructor analogy: automated reporting
without SC)
 Design & Production Preparation phases:
continuous monitoring of up-to-date
weight and CG by including CAD data,
comparing to previous estimates &
revisions, analyzing deviations and trends.
(ShipConstructor analogy: on-board
weight tracking, non-CAD weight items)
ShipWeight - technology & environment
 Windows application, SQL
Server
 Compatible with SQL Server
2000, 2005 and 2008
 Running on Windows XP,
Vista & 7
 Multi-user application
 Virtually unlimited number of
simultaneous users
 Can handle large amounts
data (millions of weight
items)
 Supports remote access
 Scalable!
 First released in 1995
 Version 11.0 ETA Fall 2011
SW + SC: benefit from Experience
Reuse and Utilize Your As-built Data
Contract
Delivery
Design/FEED
Production
Development/Detailed design
ShipWeight
Estimation based on past
weight data using parametric
ratio formulas
ShipWeight
Administration of weight data
available from other systems,
like ShipConstructor (import)
Data from the complete
vessel is reused in new
estimations
ShipWeight
Tracking and monitoring
reported weights
Estimation: SW & SC complementary
 Hundreds of parametric estimation methods included
 Founded upon historic data support
 Methods are customizable
 User can create new methods
Weight Tracking/Monitoring:
SW & SC complement each other
 Combined single record- and table view
 User-defined setup of input dialog layout
 Macro management by item code (user
defined fields)
 Up to 100 user-defined fields (SC UDA)
 Maturity & Contingency
 Modules & Sections
 Allowance
 Fluids
 Department & Disciplines
 Sorting and filtering capability (SC Part
View and SC Project View)
 Management of groups of items
 Windows Cut, Copy and Paste
 Custom reports combine SW + SC data
Reporting - standard, custom, combined
 Crystal Reports combined with ShipWeight custom codes makes it easy to
report at various levels of coordinates and coded subgrouping
 Export to text file, Excel, Word & PDF format
 Group, summarize and display graphs for the quantities you want
 Combine with ShipConstructor data (see example later this morning)
Sample reports
ShipWeight: more than just . . .

 User meetings
 Maintenance and support
 Customize work breakdown
structures
 Develop links to existing software in
the organization
 Tailor reports and output
 Establish historical databases
 Weight estimation & weight
monitoring
NSRP: an interface is born
 Concept: a long requested feature, materialized by DRS, BAS, NDAR, SSI
USA
 DRS (Advanced Marine Technology Center): “Leveraging Detail Design
Data in Weight Engineering", selected March 2012
 Team: Marinette Marine, VT Halter Marine, ShipConstructor Software,
DRS, BAS
 ShipConstructor is the natural choice to be the lab-rat thanks to the
analogies and synergies described before, but also thanks to on going
strategic fundamental development. Other ship-CAD systems lack the
required model management technology (UDAs, multiple PHs, etc.).
SW / SC interface: the plan
 Focus: efficient use of detail design data in support of weight engineering.
Data dumping procedures are inefficient.
Combine collecting, analyzing, and reporting weight data with evolution of
the product model used for planning, purchasing and production.
 Map existing business processes of team members:
 Identify SW / SC common data
 Document data identification and cataloguing strategies for
common and unique data
 Search for and eliminate duplicate data entries
 Macro-manage data (user defined fields / UDAs, WBS / PH, etc.)
 Develop data transfer methods for accuracy and timeliness
 Develop an interface strategy for the above
GOALS
 More accurate weight, CG, and Inertia data in
Weight Engineering
 More timely data, with less effort
 Earlier detection of negative trends in mass
properties
More complete and accurate as-built weight
databases
Prototype 1
 Pull & Push data via ShipConstructor and ShipWeight APIs
 Neutral format interface for open communications but also for black
box data transfer recording
Prototype 2 ?
Analogy with SC Enterprise Platform Connectors
 Connectors
