Integrated Information

Management

• Focus: Information flow in shipbuilding production

systems

• Business Problem

– Proliferation of proprietary formats

– Complex, unmanaged flow of information

– Modifications or integration of new technologies are costly

and disruptive

– These severe restrictions limit flexibility for decisions

Basic Requirements (1)

Features to be developed:

• Identify the weld joints defined in the design process

• Define the weld sequence according to the assembly

trees

• Investigate the

influence of the weld

Basic Requirements (2)

Features to be developed

(cont’d):

• Convert design geometry

into production geometry

based on predicted material

deformation

• Shrinkage management to be separated from

the design and to become part of the

production preparation

Production Control

Workflow

Work steps require consideration of:

• Define the shipyard’s production facilities

• Define the production levels generally available at the yard

from part cutting to slipway assembly and their related

boundary conditions

• Define the weld joints

• Define the production flow which any individual part has to

pass through from cutting up to final assembly

• Calculate the shrinkage values for each part applicable for the

selected production flow

• Distort all part geometries for nesting and cutting
