Abstract
Dynamics of a floating breakwater to waves is examined theoretically and experimentally. Both methods, the time domain analysis and the frequency domain analysis, are applied to estimate the dynamic response of a floating breakwater to waves. Especially, focusing on the effect of wave drift forces on the variation of restoring forces by the mooring system, the resultant dynamics and the performance of the breakwater are clarified. In addition to the above examination, effect of the damping forces on the dynamics of the floating breakwater is also studied. Key words: Wave response, Floating breakwater, Wave drift force, Damping force
