Wave-and Wind-induced Responses of the Semisubmersible Wind Energy and Flap-type Wave Energy Converter Based on Experiments

摘要

This paper presents a study of the wave-and wind-induced responses of the combined energy concept Semisubmersible wind energy and Flap-type wave energy Converter (SFC) under operational and survival conditions based on experimental data. The measured responses that are studied include the motions of the semisubmersible, the rotation of the flap-type Wave Energy Converters (WECs), the tension of the mooring lines, the internal loads in the arms of the WECs, the bending moment at the base of the wind turbine tower, and the produced power by the WECs. The effects of both the change of the mean heeling angle of the SFC and the aerodynamic damping are studied. In consideration of a constant and uniform wind field, the effect of the wind loading on the structural responses of different parts of the WECs of the SFC is small.
