Abstract
An apparatus for generating offshore wind employs shallow draft floats supporting a lattice tower with a wide base having a single-line anchoring providing passive yawing. The lattice structure supports a horizontal shaft at both ends of the shaft for rotating a rotor assembly. Mechanical energy from the rotor may be transferred to electrical generation equipment located at the base of the structure.
Claims4
An offshore wind turbine comprising:
- a truss structure supported above a water surface by shallow draft floats;
- and
- a wind turbine supported atop said truss structure;
- and
- said shallow draft floats fixedly engaged with a rectangular frame, and arranged in a rectangular pattern having four straight sides;
- and
- a triangular frame having three straight sides, one side fixedly engaged and parallel with one straight side of said rectangular frame;
- and
- a hitch point on said triangular frame at the end of two of said three straight sides;
- and
- said hitch point removably engaged with a mooring apparatus;
- and
- electrical-production equipment electrically coupled with said wind turbine, and a first transmission line from said electrical production equipment to said hitch point;
- and
- said first transmission line removably engaged with a second transmission line that is electrically coupled to a land based electrical grid;
- wherein
- mooring said wind turbine from said hitch point allows the wind turbine to yaw passively and said wind turbine may be towed by said hitch point.
