Abstract
A hybrid offshore wind turbine includes a monopile, friction wheel, and suction bucket.
Claims20
A hybrid foundation for an offshore wind turbine comprising:
- an elongated monopile extending from a first end to a distal second along an axis, the first end configured to be inserted into a sea floor,
- a friction wheel having an outer annular surface and an inner annular surface that defines an opening through which the elongated monopile extends, the friction wheel extending transverse to the axis and being configured to increase lateral load bearing capacity of the elongated monopile upon insertion into the sea floor, and
- an annular suction bucket that extends from the friction wheel towards the first end of the elongated monopile, the suction bucket configured to be driven into the sea floor by pressure differentiation within the bucket during installation of the hybrid foundation.
