Abstract

Based on the concept of space sharing and cost allocation for the integration of wave energy converter and floating breakwaters

a three-pontoon floating breakwater-WEC integrated system is proposed. A numerical model is established using computational fluid dynamics methods to study the performance of the multi-pontoon floating breakwater

and the effects of PTO damping and draft on the energy capture and wave attenuation performance are investigated. The results show that the split-module design of the breakwater has an obvious effect on improving the energy acquisition of the integrated system with the same total volume

and the staggered configuration of the resonance frequency of the front and middle pontoons significantly broaden the effective frequency band. The design of the front pontoon with a triangular shape at the bottom can further improve the energy capture level. The reasonable selection of the PTO damping coefficient and the increase of the draft of the rear pontoon can improve the performance of the integrated system in terms of wave dissipation.
