Shrinkage value in a hull part increases by every heating of welding and Straitening at the production process of sub-assembly, assembly, etc. This recovery used to be solved by adding its net dimentions many types of excess. This report describes an approach to the solution by introduction of the computer-aided hull parts generation system which has been already applied. The logic is to configure and fabricate the hull parts digitized in the system in their gross size including the shrinkage value, and the features are to operate the system as follows ; 1) Design department prepares the net data output of the hull part configuration, and porduction department provides their gross data output. 2) Excess length for the shrinkage recovery is given at not only both the ends but also all the heating internals of the hull parts.
