Abstract
A wave energy conversion (WEC) system includes a float body, a heave plate, a tether, and a controller. The tether couples the heave plate to the float body. The controller controls the tether between survivability modes. Each survivability mode adjusts a tension and/or length of the tether.
Claims10
A wave energy conversion (WEC) system comprising:
- a float body configured to float on or at a surface of a body of water, said float body comprising one or more ballast chambers of sufficient size to hold enough ballast for the float body to achieve negative buoyancy to submerge beneath the water surface in response to a survivability event;
- a heave plate;
- at least one tether coupling the heave plate to the float body;
- and
- a controller to control the at least one tether between survivability modes, wherein each survivability mode adjusts a tension and/or length of the at least one tether.
