An offshore wind turbine generator comprising:
- an elongated, buoyant tower having an internal service tube, the internal service tube extending from the lower end of the elongated, buoyant tower to above a waterline when in use;
- a connection arrangement comprising an upper connection assembly and a lower connection assembly;
- an intermediate tension/torsion leg being arranged between the upper and lower connection assemblies,
- wherein the connection assembly is adapted for lowering and raising within the internal service tube.
An offshore wind turbine generator comprising:
- an elongated buoyant tower;
- and
- a connection assembly comprising a universal joint and yaw assembly,
- wherein the universal joint and yaw assembly comprises a rocker arm and a ring-shaped member connected to the rocker arm.
An offshore wind turbine generator comprising:
- an elongated, buoyant tower and a wind turbine mounted at a top of the tower,
- wherein a upper end of the tower, adjacent to an attachment point for the wind turbine, is offset at an angle from a vertical axis of the tower.
