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

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, Semi-submersibles, 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

Development/Detailed design

Contract Delivery

Design/FEED Production

Estimation based on past weight data using parametric ratio formulas

ShipWeight

Administration of weight data available from other systems, like ShipConstructor (import)

ShipWeight

Tracking and monitoring reported weights

ShipWeight

Data from the complete vessel is reused in new estimations

Reuse and Utilize Your As-built Data

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 . . .

Additional Features Weight Distribution Curve Moment of Inertia calculation Visual Sanity Checking System Weight Distribution 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.).

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

SW / SC interface: the plan

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

GOALS

Pull & Push data via ShipConstructor and ShipWeight APIs

Neutral format interface for open communications but also for black box data transfer recording
