The mooring system is important for a floating wave energy converter since it provides a positioning function and significantly affects the motion characteristics of the wave energy converter. In the present study, a novelty mooring system, which works as a single point mooring assisted with a yaw-restrain system, is proposed. Based on a potential flow theory, a numerical study is carried out. The response amplitudes induced by the wave under different incident angles are presented. The numerical study shows that the incident angle is a key factor of the motion amplitude, and that for each special wavelength, there is an optimal incident angle. A coupled analysis is carried out for the wave energy converter with its mooring system. A controlling method is presented for a given incident angle.
