초기 선체 구조 모델을 기반으로 한 선체 블록의 물량 정보 생성 및 블록 탑재 시뮬레이션

Abstract

At the initial design stage, the generation process of the production 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 been manually performed using 2D drawings, based on the data of parent ships, and subjective intuition from past experience. To make these processes automatic, the accurate generation method of the production material information and the convenient simulation method of the block erection based on the initial hull structural model(3D CAD model), were developed in this study. Here, the initial hull structural model was generated from the initial hull structural CAD system early developed by us. To evaluate the developed 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 initial design stage.
