Abstract: As an improvement and optimization of the "Eagle I" wave energy device which has been successfully put into power generation, the one-base multi-buoy floating "Sharp Eagle" wave energy converter(WEC) is a novel offshore floating WEC array taping wave power. The "Sharp Eagle" WEC introduced in this paper consists of 4 Eagle head absorbing buoys, 1 buoyancy tank, 1 underwater appendage, 1 semi-submersible ship, 1 energy conversion system, as well as 1 mooring system and other components. As a specially designed structure of the "Sharp Eagle" WEC, the 4 Eagle head absorbing buoys are installed on the underwater appendage in a symmetrical way, sharing the energy conversion system and the mooring system. Through a series of tank model tests, it is able to obtain the optimal loads matching varied waves, measure the primary and secondary energy conversion efficiencies of the "Sharp Eagle" WEC model under different wave conditions, and gain the force of the mooring system. The results show that the model has good hydrodynamic performance. The capability of the model to capture wave energy is not affected by the direction of incident waves. The mooring system plays an important role in fixing the model and improving the capture efficiency of the "Sharp Eagle" WEC.
