After CSR is in effect, a matter of concern is how many to increase in terms of weight due to apply it to the ship and what difference it is comparing between existing rule and CSR rule. The concepts of CSR are to make the ship safer, more robust. and the design requirement clearer. Furthermore it pursues longer life of ship in fatigue strength. By reasons of those, most of requirements are stronger than before. Therefore many part of ship should be reinforced and the weight of ship can be increased. Under those circumstances, the builder should make an effort to define the CSR and to find the methods to manage well this situation. In this study, we performed 3D Cargo hold and Fine-mesh F.E analysis and deduced a conclusion and introduced new detail design.

This paper presents a method, which couples the boundary integral terms in the thin magnetic materials with standard FEM used to analyze the rest of it, for analyzing the magnetic fields. The proposed method retains the sparsity and symmetry of the final system matrix, the merits of standard FEM and eliminates the need for fininte elements in the thin magnetic materials, thereby reducing necessary capacity of computer memory and computing time. To verify the usefulness of the proposed alogorithmn, an examples, coil with source currents and thin magnetic materials, is chosen and analyzed. the results are compared with those of the standard FEM by coarse mesh and the proposed method, using standard FEM by fine mesh as a reference.
