The theoretical analysis for the stochastic wave response of a large circular floating island with ring-shaped breakwater has been developed based on a wet-mode superposition approach. The ring-shaped breakwater is located around the circumference of the floating island. The fluid-coupled free vibration and stochastic wave response of a ring-stiffened circular plate with tension-leg mooring system are formulated by energy method within the framework of hydroelasticity. Numerical calculations are carried out to show the variation in the dynamic behavior of floating island due to ring-stiffener. It is concluded that the contribution of vibrational modes with higher Fourier wave number to the overall dynamic response may be considerably influenced by the bending and torsional stiffness of ring-shaped breakwater.
