In this research, we focus on a triangular and semi-submersible FOWT which has three wind turbines and is assumed to be installed at the sea with depth of 40 meters. This floating model is suggested in a cooperative research with RIAM (Research Institute for Applied Mechanics), Kyushu University. We develop a practical computer program which enables us to calculate approximately the motion characteristics, and some effects such as nonlinear viscosity damping force, mooring, wind and steady displacements are considered.

KEY WORDS: multiple turbines floater; frequency domain green function method; catenary theory; memory-effect function
