The wave energy converter named "Mighty Whale" is a floating oscillating water column device to extract the energy and convert it a necessary from of energy, electricity, heat or compressed air energy. If wave energy could be completely absorbed the converter device, wave energy and utilization of coastal sea, the economic value of wave power would be greatly increased.
Consequently, the floating wave energy converter such as the Mighty Whale has possibility to be utilized as a floating break water, and it creates the calm sea area behind the converter device where "aquiculture" or many marine sports available.
