Dynamic cable support for floating offshore wind turbines

An apparatus comprising:

• a wind turbine configured for floating on a surface of water, wherein the wind turbine is operable to generate electrical energy, and wherein the wind turbine comprises:
• a floating base configured to support the wind turbine on the surface of water;
• a cable configured to transmit the electrical energy;
• a first sheave configured to support at least one first part of the cable;
• and
• a second sheave configured to support at least one second part of the cable,
• wherein the cable is reeved between the first sheave and the second sheave,
• wherein the first sheave is operable to impart a predetermined force to the cable to thereby maintain the cable at a predetermined tension,
• wherein, when movement of the water causes an increased tension in the cable, the increased tension in the cable forces the first sheave to move toward the second sheave decreasing the distance between the first sheave and the second sheave to thereby permit the cable to be pulled out from between the first sheave and second sheave and move with the water;
• and
• wherein, when the water does not cause the increased tension in the cable, the first sheave moves away from the second sheave increasing the distance between the first sheave and the second sheave to thereby retract the cable to between the first sheave and the second sheave.
