A two-body wave energy converter utilizing a linear, universal modular absorber. A linear module, contains a direct drive linear machine for converting linear mechanical motion into electrical energy. The linear module is connected between two oscillating mechanical bodies, exploiting their relative motion. A wave activated floating body follows the wave motion, while a reaction body is tethered to a mass on the seabed providing a stable kinematic reference in operational waves. In large waves, the mass on the seabed lifts, providing heave compliance to the whole wave energy converter reducing ultimate loads in survival wave conditions.

The present invention provides a novel, floating, offshore wind turbine (FOWT) structure, referred to as a yawing buoy mast (YBM) structure. The YBM platform vertically combines a submerged spar buoy with outrigger legs and a mast on which a wind turbine nacelle is mounted. Compared to a conventional spar buoy wind turbine, weight is significantly reduced by optimizing how loads are borne and reacted by the floating structure. The mass of the YBM platform is reduced relative to the energy captured by the turbine resulting in a reduction in the cost of energy (COE). Platform load dynamics are coupled with the dynamics of the wind turbine by integration of the YBM platform and turbine controllers.

Abrégé

A power-generating device located in or on the surface of the ocean for generating power utilizing the energy in ocean wave motion. The device is moored to the bow and stern at ~45° to incoming ocean waves, and with a yawing capability to adjust to change in wave direction. The device delivers power to a shore grid via a submarine cable from a generator. A rotational driving torque to the generator is produced by two long counter-rotating drive tubes, which are held by bearings in the bow hull and the stern hull of the device. As an alternative, hydraulics may be employed for energy capture and power smoothing and used to provide the rotational torque through a hydraulic motor to drive a generator. The main body is partially submerged and has multiple pod floats connected to the structure by rocker arms with bearings through which the drive tubes pass or double-acting hydraulic rams between the arms and the main body which capture energy through pod displacement and store it in accumulators. Rotary torque of the drive tubes is produced when the pods move up and down according to motion of the waves and is transmitted to the generator to generate power. In the hydraulic case, energy is stored in accumulators as pressure due to the double-acting hydraulic pistons pumping when the pods move up and down according to the motion of the waves. Hydraulic pressure drives a pump, which provides torque to the generator.

A wind or water turbine mounted atop a support tower or tethered underwater drives a hydro-pumping system. The turbine converts wind or water energy into a driving torque applied to the hydro-pump. The hydro-pump forces water through a pipe transmission system to an onshore facility. On shore, the resultant pressurized fluid-flow propels a hydroelectric generating system to produce electricity or may first be used in a Reverse Osmosis desalinization process and the byproduct in part used to propel a hydroelectric generating system to produce electricity. The cold-water discharge from the hydroelectric generating system and/or from the desalinization process is used for onshore district or power plant cooling purposes.
