Patent number: 10711760Abstract: A wave operated assembly (20) configured to be submerged in a body of water (12), the wave operated assembly (20) comprising a wave actuated member (24), a second portion and a piston assembly, pressure chamber (22) or spring coupled between the wave actuated member (24) and the second portion. The wave actuated member (24) and the fixed portion each define part of a first chamber (22) or volume comprising or configured to receive a fluid. A lower portion of the wave actuated member (24) at least partly defines a free surface (35) between the fluid within the first chamber (22) or volume and the body of water (12). The wave actuated member (24) is movable relative to the second portion. The piston assembly, pressure chamber (22) or spring is configured to apply a force on the wave actuated member (24) that works in opposition to a force on the wave actuated member (24) due to the fluid in the first chamber (22) or volume.Type: GrantFiled: August 12, 2016Date of Patent: July 14, 2020Assignee: AWS Ocean Energy LimitedInventor: Simon Grey

Publication number: 20130192218Abstract: An energy conversion device, a removable assembly for use with the energy conversion device and an associated methods. The energy conversion device comprises a flexible diaphragm configured to be located between a first fluid and a second fluid and being moveable in response to variations in at least one of the first and second fluids to permit energy transfer between said fluids; and a limit apparatus configured to limit movement of the diaphragm at a limit position, wherein the limit apparatus defines a contoured contact surface configured to be engaged by the diaphragm when in its limit position.Type: ApplicationFiled: March 11, 2011Publication date: August 1, 2013Applicant: AWS OCEAN ENERGY LIMITEDInventors: Anne Briffett, Lorn Macdonald

Publication number: 20110185721Abstract: An energy conversion device, such as a wave energy conversion device has a diaphragm (30) attached to a frame (100, 110) with opposed lateral edges of the diaphragm (30) being attached to the frame (100, 110) with an āSā-shaped configuration. The diaphragm (30) and frame (100, 110) form a cell (20) for fluid which is driven by movement of the diaphragm to drive a power-take-off device such as a turbine mounted in a duct leading from the cell (20). The diaphragm may be reinforced by cords, preferably vertical cords. Multiple cells (20) may be arranged in a ring, or the duct from one cell may lead to a reservoir or to another cell.Type: ApplicationFiled: May 13, 2009Publication date: August 4, 2011Applicant: AWS Ocean Energy LimitedInventor: Donald Milne Turner

Publication number: 20110158752Abstract: A pile system comprises a base assembly (10) adapted to be mounted on a ground surface and a first pile (50) adapted to be extended through the base assembly (10) and into the ground. The system includes a drilling assembly comprising a drill bit unit (54) secured relative to a lower region of the first pile (50) to drill a hole to accommodate the first pile (50) therein. The base assembly (10) is adapted to engage the first pile (50) to prevent rotation thereof. In one arrangement the system comprises a second pile (80) with associated drilling unit (82) configured to extend through the first pile (50).Type: ApplicationFiled: July 13, 2009Publication date: June 30, 2011Applicant: AWS OCEAN ENERGY LIMITEDInventor: David Hitchin
