Abstract
A system and method for a for a wave energy converter device that is an axisymmetric point absorber which operates in a tension only condition over a large stroke that can operate in the given wave environment so as to eliminate the need for end stops in normal operation whereby the wave energy converter device has a floating hull with an interior Power Take Off (PTO) that uses an impedance control scheme for impedance matching with the wave environment in which it is deployed so as to maximize electrical power output as compared with a passively operating device of similar size.
Claims21
A wave energy system comprising:
- a generator;
- a power takeoff drum coupled to the generator;
- and
- a control system controlling the generator to generate electricity;
- an electrical-optical-mechanical cable having electrical conductors and optical fibers integrated therein;
- and wherein the electrical conductors are configured to transmit generated electrical power to a subsea or shore-based facility.
An integrated subsea wave energy converter AI data center system comprising:
- a seabed platform configured for deployment on a seafloor;
- a power take-off pressure vessel mounted on the seabed platform, the power take-off pressure vessel housing a power take-off drum, a main shaft supported by bearings with rotary seals, and a generator coupled to the main shaft;
- at least one data center pressure vessel mounted on the seabed platform adjacent to the power take-off pressure vessel, the at least one data center pressure vessel housing computing hardware and power electronics;
- a surface float connected to the power take-off drum via a first tether, the surface float configured to rise and fall with ocean waves;
- and
- a pre-tension float connected to a pre-tension shaft within the power take-off pressure vessel via a second tether, the pre-tension float configured to maintain tension on the first tether during wave cycles;
- wherein electrical power generated by the generator is transmitted directly to the computing hardware within the at least one data center pressure vessel.
An integrated subsea wave energy converter center system comprising:
- a seabed platform configured for deployment on a seafloor;
- a power take-off pressure vessel mounted on the seabed platform, the power take-off pressure vessel housing a power take-off drum, a main shaft supported by bearings with rotary seals, and a generator coupled to the main shaft;
- at least one payload pressure vessel mounted on the seabed platform adjacent to the power take-off pressure vessel.
