Abstract
An apparatus that a wind turbine configured for floating on a surface of water, wherein the wind turbine is operable to generate electrical energy. The wind turbine can include a floating base configured to support the wind turbine on the surface of water, and a cable configured to transmit the electrical energy. The wind turbine can also include a first sheave configured to support a part of the cable, and a second sheave configured to support a part of the cable. The cable is reeved between the first sheave and second sheave, and the first sheave is operable to impart a predetermined force to the cable to thereby maintain the cable at a predetermined tension.
