Abstract
In the initial design stage, the generation process of the productin material information of a building block and the simulation process of the block erection, which are required to perform the production planning and scheduling have beem manually performed using 2D drawings. based on the data of parent ships and subjective intuition from past experience, To make these processes automaic the accurate generation method of the production material information and the convenient simulation method of the block erection using the #D CAD model were proposed in this study. Here, the 3D CAD model was generated from the initial hull structural modeling system early eveloped by us. To evaluate the proposed methods, these methods were applied to corresponding processes of a deadweight 300,000ton VLCC. As a result, it was shown that the production material information of a building block can be accurately generated and the block erection can be conveniently simulated in the inintial design stage.
