Definitions

  • a point absorber within the context of wave energy converters a number of different approaches are known in the art.
  • One particular type is known a point absorber.
  • Such known point absorbers and one particular type of such point absorbers is described in our earlier patent, EP1295031.
  • EP1295031 In this arrangement a floating body or surface float is connected to a submerged body. Both the floating body and the submerged body are of a large dimension, albeit the submerged body is much greater than that of the surface float.
  • connection system for use with a wave energy converter of the type having a floating body and a submerged body, the connection system being configured, in use, to provide for a coupling of the floating body to the submerged body and wherein the connection system comprises a plurality of discs threadable on at least one connection cable which is under tension, the connection cable being configured to be coupled at one end to the floating body and at a second end to the submerged body, and wherein the discs are arranged relative to one another to restrict lateral movement of the floating body relative to the submerged body.
  • the cables are desirably arranged adjacent to a central axis between the two bodies. Such an arrangement allows for bending of the discs relative to one another.
  • the spacing between the adjacent cables is desirably such as to provide a degree of flexing.
  • connection system 115 that is to some degree compliant when subjected to forces other than those along the main axis.
  • a connection system comprises a plurality of discs 120 threadable on at least one connection cable 125 , the connection cable 125 being configured to be coupled at one end to the floating body 105 and at a second end to the submerged body 110 .
  • the connection cable(s) are provided in tension. The arrangement of the discs relative to one another is such to restrict lateral movement of the floating body 105 relative to the submerged body 110 .
