To design floating body such as a floating wind power generation, it is necessary to develop the calculation method to estimate the effect of the fin installed in order to reduce the motions of the body and the behavior of the floating body in resonance frequency. The purpose of our study is to develop the numerical simulation method with high accuracy to represent the behavior of floating body in nonlinear wave by using vortex method. <br>In this paper, motions of moored rectangular and triangular floating bodies in waves are calculated by the vortex method based on the Core-Spreading method. To calculate the vorticity generation from the body surface, the vorticity layer and the vorticity shedding models are used. And total pressure acting on the body is calculated by using the boundary integral equation represented by the velocity and the vorticity, deduced from fundamental equations of viscous fluid. The calculated motion amplitudes of the moored body in waves are compared with the experimental results and the calculated results by the vortex method agree well with the experimental results.
