概要

In the previous papers, the authors have developed an initial hull structural planning and hull weight optimization system for double hull tankers. This system can estimate net hull steel weight and search for a design candidate that minimizes the hull weight from a number of design candidates. In this paper, an initial hull structural planning and hull weight optimization system with Genetic Algorithm (GA) on account of expansion of kind of design variables and searching of the wide field is developed. The system is based on the design process traditionally used in shipyard, and hence; there is difficulty in satisfying the required cargo capacity. In order to remove this drawback, a method is proposed with aid of bit arrangement for genes in GA optimization process. The hull structure optimization system in initial planning is created and good numerical performance is shown here.
