A closed-loop hydraulic apparatusfor converting wave energy comprises a pumpfor pumping a fluid through the apparatus. The pumpincludes a bodydefining a chamber, and a pistonthat partitions the chamberinto a working sideand a blind side. A buoyant actuator is connected to the piston. An inletis connected to the working sideof the chamberso that the fluid is able to flow from the inletand into the working sideof the chamber. An outletis connected to the working sideof the chamberso that the fluid is able to flow from the working sideof the chamberto the outlet. A hydraulic controlleris operable to control the pumpby controlling the pressure of the fluid at the inletand the outletso as to optimise the output of the pumpin response to tidal variations and/or sea state. The pressure of the fluid at the inletand the outletis controlled in accordance with a control algorithm.

Hydraulic apparatus

A wave energy conversion system for harnessing wave energy in a body of water and converting the harnessed wave energy to pressurized fluid, and also a method of deploying such a wave energy conversion system. The wave energy conversion system comprises a unit including a buoyant structure responsive to wave motion, at least one pump and at least one tether adapted to be operably connected between the pump and a fixture below the unit, whereby movement of the buoyant structure relative to the fixture in response to wave motion converts harnessed energy to pressurized fluid. The unit is adapted to be deployed by moving the tether into coupling engagement with the fixture upon actuation of the pump in a manner causing movement of the tether into engagement with the fixture.

Deployment system

An apparatus is provided for harnessing ocean wave energy, wherein the apparatus relieves excessive loadings on components to avoid damage thereof in adverse wave conditions. The apparatus includes a buoyant actuator and a pump anchored within the body of water. Fluid at high pressure is pumped ashore by the pump, energy is extracted as useful work at an on-shore plant, and the resultant reduced pressure fluid is returned to the offshore pump to be re-energized. The buoyant actuator is operably connected to the pump by tether and is buoyantly suspended within the body of water above the pump. The buoyant actuator is provided with a connector that includes a damping mechanism configured to maintain a substantially rigid connection between the hollow body and the tether until such time as loading therebetween exceeds a prescribed load whereupon the damping mechanism facilitates limited relative movement therebetween to relieve the loading.

Wave energy conversion

A method for analysing a chemical substance containing quadrupolar nuclei to determine a measurable characteristic of the substance. The method includes irradiating the substance with RF energy in a prescribed manner to stimulate NQR of certain quadrupolar nuclei within the substance. Then receiving and processing a signal emitted from the substance to isolate an NQR signal therefrom. Thereafter analysing the NQR signal to obtain a measure of the characteristic of the substance; and providing an output indicative of the measure for analytical purposes. Specific methods for analysing a chemical substance during production thereof to determine a characteristic of the substance indicative of the quality thereof, and for searching for chemicals together with specific systems are also described.
