Abstract: 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).

Abstract: A mooring system and/or a rigid harness (2) for a floating aquatic structure (1) includes first and second ends, and the first end is pivotably attachable to the structure (1) such that in use the harness (2) may pivot about a single pivot axis (23) through a range of angles relative to, and including, the vertical. The harness (2) further includes one or more mechanical and/or umbilical connections (28,30,32) adjacent the second end thereof.

Abstract: A wave power apparatus includes a plurality of buoyant elongate body members, at least one adjacent pair of body members being interconnected by a linkage unit to form an articulated chain. Each body member of said pair is connected to the respective linkage unit by linkage means permitting relative rotation of the body members. A power extraction means, being located substantially within each linkage unit, is adapted to resist and extract power from the relative rotation.

Abstract: A mooring system for a floating aquatic structure includes a harness, a primary weight, and a first anchor. The harness has first and second ends. The first end is pivotally attached to the structure. The primary weight is removably attached to a connecting line and suspended from the second end of the harness. The anchor is removably attached to the primary weight to resist movement of the structure in a first direction.

Abstract: 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 of adjacent cylindrical members is connected to each other by a coupling member (5a, 5b) which permits relative rotational movement of the cylindrical members about at least one transverse axis (40). Adjacent coupling members may permit relative rotation about mutually orthogonal transverse axes (A, B). Each coupling member is provided with elements such as a set of hydraulic rams (33, 34, 35) which resist and extract power from the relative rotational movement of the body members, and which can provide applied constraints to rotation about one or both of the transverse axes. The transverse axes of rotation (A, B) are skewed from the horizontal axis (104) and vertical axis (100) by a roll bias angle (&psgr;), selected to optimize the dynamic response of the apparatus to incoming waves.
