Patent number: 9726141Abstract: A wave absorber element of the front pivot type for the absorption of wave energy from water has a front end comprising a front pivot axis around which the absorber element swings under operation, and an absorber element body substantially defined by a front side extending from the front end to a lower rear edge, a rear side extending from an upper rear edge to the lower rear edge, a top side extending from the front end to the upper rear edge, and lateral sidewalls defining the width of the absorber body in an axial direction parallel to the front pivot axis. The lower rear edge is located in a first radial direction from the pivot axis, the upper rear edge is located in a second radial direction from the pivot axis, and the first and second radial directions define an acute tip angle (alpha) of the absorber element.Type: GrantFiled: July 4, 2012Date of Patent: August 8, 2017Assignee: Floating Power Plant A/SInventor: Anders Køhler

Patent number: 9617971Abstract: An absorber unit for absorption of wave energy from a body of water comprises a pivoting absorber element with a front end around which the absorber element reciprocates between turning positions. The absorber unit has a frame structure defining an absorber chamber and is at rest with respect to the body of water. The frame structure pivotally supports the absorber element within the absorber chamber from a horizontal front pivot axis above an average surface level of the body of water, wherein the absorber element in an idle position under still water conditions is partially submerged, with an idle draft of the absorber element being determined by the depth of submersion of the lower rear edge below the average surface level. A bottom plate attached to the frame structure has a front portion arranged underneath the absorber element and an upwardly projecting rear portion aft of the absorber element.Type: GrantFiled: July 4, 2012Date of Patent: April 11, 2017Assignee: Floating Power Plant A/SInventor: Anders Køhler
