Abstract To provide the precise production material information for production planning, a 3D solid model for hull structure must be generated in the initial stage of ship design. However, in the case of most shipbuilding companies, the 3D solid model could not be generated in this stage because of limitation of time and lack of 3D CAD systems supporting initial hull structural design. Thus, the necessity of an efficient initial hull structural CAD system for CAPP (Computer-Aided Process Planning) in the initial stage is increasing. In this study, a semantic product model data structure in view of initial hull structural design was first proposed. And, an efficient initial hull structural CAD system was developed based on the proposed semantic product model data structure. By using the developed system, it is possible to perform rapid product modeling and to generate automatically the 3D solid model for hull structure and the product material information for CAPP at any required time in the initial stage. Finally, the applicability of the developed system was verified through application to deadweight 300,000 ton VLCC's product modeling.
