Abstract

A wave energy conversion system comprising a wave energy absorber, which in a first arrangement is configured to reduce parametric resonance which causes large pitch motion in the wave energy absorber, and thus optimise power conversion efficiency. In a second arrangement, the wave energy absorber is configured to have a variable water piercing area so as to experience parametric resonance, which can be exploited to increase power capture.
