The authors started this research on estimation method of responses for floating structures using Computational Fluid Dynamics (CFD). This paper is first step, which has potential to be very valuable to the engineering community. The numerical method used in this study is the Moving Particle Semi-implicit (MPS) method 1) 2) , which is based on particles and their interactions. MPS method that was developed recently is one of particle method. The particle number density is implicitly required to be constant to satisfy incompressibility. A semi-implicit algorithm is used to for two dimensional incompressible non-viscous flow analysis. The particles whose particle number densities are below a set point are considered as on the free surface. In this paper, first, the authors explain the outline of MPS method that Kshizuka et al. developed. You can see more details of this method by references. And the calculation test of column collapse problem is carried out to check our code that we developed. Second, the modeling of free surfaces is explained. And the authors proposed the way to skip irregular data of wave height. Validation of wave profiles was carried out comparing Stokes theory. Third, calculation results of floating body are showed. This method of calculating response of floating structure is by Koshizuka et al. 3) . Finally, the authors show calculation results of wave exciting forces by MPS method comparing singular point distribution method (SDM).
