This paper deals with a design tool using CFD and criteria for ship structures under impact pressure loads due to sloshing, slamming and green water. This study focuses on the development of numerical techniques for computing fluid-structure interaction and for evaluating the seakeeping performance of a ship in nonlinear wave with breaking. This paper also presents a prediction of a local high-impact pressure caused by a strongly nonlinear wave. The developed numerical model was applied to ship-wave interaction for evaluation of the seakeeping performance of a ship in waves. The heave, pitch motion and added wave resistance were compared with experimental results and strip theory, and the results were in quite good agreement with them. It can be seen that the proposed model can accurately capture a nonlinear free surface with wave breaking generated by a ship motion in wave and calm water.
