Patent number: 11905919Abstract: Disclosed herein is a power generating apparatus for extracting energy from flowing water. The apparatus comprises a buoyancy vessel, and a turbine assembly coupled to the buoyancy vessel which comprises a turbine rotor mounted to a nacelle, and a support structure. The turbine assembly is pivotally moveable between a first position and a second position. When the power generating apparatus is floating on a body of water, in the first position the nacelle is fully submerged below the water surface; and in the second position at least a part of the nacelle projects above the water surface. Movement of the turbine assembly from the first position to the second position is buoyancy assisted, for example by providing the turbine assembly with positive buoyancy or selectively increasing its buoyancy.Type: GrantFiled: July 13, 2021Date of Patent: February 20, 2024Assignee: Orbital Marine Power LimitedInventors: Jonathan Meason, Calum Miller, William Annal, Andrew Harrison, Axel Bondoux, Ross McKay Henderson, Carn Nathaniel George Gibson, Charles Andrew Edward Taylor, Jonathan Ian Benzie

Patent number: 9018779Abstract: An improved apparatus for extracting power from waves is provided. The apparatus (10) comprises at least one pair of buoyant body members (12A,12B) connected to one another by a coupling (14) which permits relative rotation between the body members (12A,12B) about first and second non-parallel axes of rotation (A,B). The apparatus further comprises a power extraction system comprising at least one power extraction element (16) having a first end connected to a first of the body members (12A) and a second end connected to a second of the body members (12B) such that the element resists and extracts power from the relative rotation between the body members (12A,12B).Type: GrantFiled: November 22, 2010Date of Patent: April 28, 2015Assignee: Pelamis Wave Power LimitedInventors: Richard Yemm, Ross McKay Henderson
