Abstract

The design and working principle of a new megawatt-class wave energy converter （WEC） is introduced briefly, which consists of a semi-submersible floating body, a wave energy capture system, an energy conversion system, and a mooring system. The unstable wave energy is converted into stable electric energy by using a sharp eagle wave-absorbing floater and a hydraulic energy conversion system. Experiments on the energy capture efficiency of the megawatt-class WEC were carried out. Results show that the megawatt-class WEC can achieve highly efficient capture of wave energy. The energy capture efficiency of the megawatt-class WEC is mostly between 30% and 50%, and the maximum reaches 56.17%. The sharp eagle wave absorber has better absorbing properties in heading waves than in oblique waves. The energy capture efficiency in heading waves is 1.6 times that in oblique waves. The five wave absorbers on the same side of the megawatt-class WEC should be arranged to directly facing the predominant wave direction.
