A hydrodynamic analysis of a moored semi-submersible type floating wind platform has been carried out. Three methods are used in this study. The first method is the physical experiment that is carried out in the towing tank at the Research Institute for Applied Mechanics (RIAM), in which a movable seafloor frame to fix mooring lines and a wind generator are newly installed. The second method is the Computational Fluid Dynamics (CFD) simulation using our in-house research code RIAM-CMEN, which is used to predict strongly nonlinear wave and wind loads on the floating body in rough sea conditions. The third method is the potential flow-based numerical model, which is used as a practical analysis tool for parametric study. In this paper, the three methods are described and the accuracy of the two numerical methods to predict wave-body interactions is checked by comparison with the experiment.
