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)
Wartsila Ship Design, Norway
Ulstein Design, Norway
Aircraft Carrier Alliance, UK
SBM (Malaysia & USA)
Huntington-Ingalls Shipbuilding, USA
General Dynamics, USA
Mazagon Dock Limited, India
SDARI, China
STX Europe OSV, Norway
Textron Land and Marine Systems, USA
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 . . .

Playground Area
Deckload Optimizer
Parent/Child Project Setup
Hydrostatics
Additional Services
Software training
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
