Abstract

A novel modular floating structure combined artificialreef and wave energy converter （WEC） is proposed, so as to make comprehensive use of marine space, biological resources and renewable energy. Considering the multi-body coupling effect and mechanical coupling effect between the hexagonal floating structure and the floating artificial reef, the coupling time-domain analysis model of the integrated structure system is established based on potential theory. The design parameters of the floating artificial reef and the WEC are preliminary optimized. The dynamic response characteristics and the power output characteristics of the new integrated structure system under typical sea conditions are studied. It is revealed that the outside floating artificial reef can produce considerable energy while reducing the influence of wave load on the inside hexagonal floating structure. In addition, the safety of the integrated structure system under extreme sea conditions is further verified.
