A wave energy converter comprises a pitching floating vessel and means for converting the pitching motion to electrical power. By varying the distribution of the ballast mass in the vessel and by varying the vessel's immersed length the moments of inertia of mass and of added mass are varied and wave-bridging is controlled. The immersed length of the vessel is varied by changing the draft of a v-shaped hull. Roll and yaw are suppressed by a vertical fin held at a substantial depth Inside the vessel is a compact pendulum that is a combination of tracked and folding pendulums. Both vessel and compact pendulum can be simultaneously and dynamically tuned over the range of periods that characterize high-energy ocean swells. |
