Patent ID: 8729723

Claim:
A floating energy generating device comprising: at least two wind turbines mounted on a floating open structure comprising a frame of submerged interconnected hollow tubes being moored to the seabed via a mooring system, each wind turbine featuring, in operation mode, a blade and rotor part mounted at the top of a tower and being connected via a cable to a submerged high voltage power export cable for exporting the electricity generated by the at least two windmills, the mooring system comprising a turntable extending at least partly above water level and being above water level attached to the open structure via an arm such that the open structure can weathervane around a rotation axis of the mooring system, the mooring system supporting on its rotation axis an electrical swivel, the stator of which is connected to the submerged high voltage power export cable and the rotor of which is connected to the cables of the wind turbines, wherein the floating open structure comprises a central control power electronic unit placed on the floating open structure connected to the cables of the wind turbines and to the rotor of the swivel, and wherein the floating open structure is connected to the turntable via a pivoting yoke comprising two interconnected arms extending from spaced-apart connection points on the open structure to the turntable, the arms including an acute angle.
