Floating apparatus and method for extracting power from sea waves

摘要: An apparatus for extracting power from ocean waves comprises a number of buoyant cylindrical body members (2, 3, 4) connected together at their ends to form an articulated chain-like structure (1). Each pair adjacent is each other by coupling member (5a, 5b) which permits relative rotational movement the about least one transverse axis (40). Adjacent may permit rotation mutually orthogonal axes (A, B). provided with elements such as set hydraulic rams (33, 34, 35) resist and extract members, can provide applied constraints or both axes. The B) are skewed horizontal (41) vertical (42) roll bias angle (γ), selected optimise dynamic response incoming waves. (γ) differential ballasting and/or mooring constraints.
