In the optimization analysis using Genetic Algorithm for the earlier steps of shipbuilding design, there is a need to perform numerous design process evaluation. Therefore, a simple calculation method is demanded in order to avoid excessive computation time. On the other hand, results with acceptable precision level also need to be obtained. The neural network analysis based on Finite Element Method might be promising. Previous study on the application of the method for minimizing construction cost of container ship shows a considered satisfaction calculation performances and results. In that study, Transfer Matrix Method was used as a simple calculation method to lessening computation time with better precision in the Neural Network System development. In this paper, the same method is applied on the analysis of Bulk Carrier, to prove the generalization of the proposed method. Modification is carried out on the use of Simple Approximating Calculation Method mentioned in Kansai Shipbuilding Designing Handbook as leading factor on the learning process of building neural network.
