Usually, the design of the hull structure is held after the principal particulars represented by the length, width and depth of a ship and the arrangement of holds and ballast tanks are decided. At this time, the scantling of the longitudinal stiffeners and their space and the thickness of the plate are left as design variables in the optimization of the hull structure. There is a possibility to get a more suitable plan if the dimensions of the compartment are given as design variables in the design of the hull structure. Hence, an optimal design of midship section with rearrangement of compartment is investigated here.Furthermore, when the building cost of the hull is classified roughly in the material cost and the assembling cost, these costs are influenced by the age and surrounded environment even though the same vessel is constructed. For example, the assembling cost is influenced by change of the construction method and increase of facilities and material cost is influenced by the steel unit price. Therefore, it is important to examine the influence which the rate of each cost of construction at the building cost gives to the design. In this study, the influence of design variables in the optimization of the midship section of bulk carrier is also investigated and the material cost and assembling costs of the optimized design plan is reported. The genetic algorithm is adopted as an optimization method.
