An analytical approach which predicts the dynamic behavior of a circular flexible floating island subjected to wind-induced waves is presented, taking into account the dynamic interaction among the island, sea water and anchor system. The floating island is modeled as an elastic circular plate with tension-legs. Based on a linear potential flow theory, the hydrodynamic pressure generated on the wetted surface of the island is obtained in closed form. The modal equations of motion of the island with or without anchor system are derived by energy method. The response quantities are evaluated as root-mean-squared values using a stationary random vibration theory. Numerical examples are presented to discuss the effects of anchor arrangement and wave characteristics on the island response.
