Structural Analysis for MR. sized Oil Tanker applied Common Structure Rule

摘要

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 differences 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 the 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.
