Abstract
The present invention describes a floating yawing spar buoy current/tidal turbine. The spar includes a spreader above the rotor(s) with the spreader tips connected to fore and aft cable yokes that transition to opposing mooring lines connected to anchors on the seabed. The spreader comprises a yaw motor, which drives gears that engage with a ring gear fixed to the outer perimeter of the spar.
Claims20
A current or tidal turbine comprising:
- a floating spar buoy, the floating spar buoy including a keel at a bottom end;
- a spreader disposed on the floating spar buoy, wherein the spreader comprises outer end connection points for attaching one or more mooring lines connected to one or more anchors;
- and
- a turbine with a drivetrain and generator disposed on the floating spar buoy for converting current or tidal flow into electricity.
1 more element
A current or tidal turbine comprising:
- a cylindrical floating spar,
- a turbine drivetrain attached to the cylindrical floating spar, the turbine drivetrain comprising a main shaft on which a rotor is mounted,
- a flow direction sensor for sensing a direction of water flow across the cylindrical floating spar,
- a spreader above the turbine, and
- a yaw motor to position the rotor in the sensed direction of water flow.
