Abstract
A novel wind-wave energy hybrid concept is presented in this paper, consists of a floating semi-submersible wind turbine and multiple point absorption wave energy converters (WECs). Numerical simulations are conducted using the hydrodynamic analysis program AQWA, based on the three-dimensional (3D) potential theory. To ensure the reliability of the numerical model, the hydrodynamic responses of the semi-submersible platform and the WECs are validated using available experimental data. Finally, three WECs with different shapes are designed to investigate the shape on the performance of this hybrid system, including platform motion, mooring line tension and power captured by the WECs. The results demonstrate that the hybrid system with the circular truncated conical WECs has the best performance compared to the other two shaped WECs. In addition, the influence of the platform motion on the performance of the WEC array is negative. Overall, this study could provide some insights for the design of other wind-wave integrated systems.
