A rotor hub for a wind turbine which can be configured between an in use or ‘operational’ configuration and a transportation configuration. In the transportation configuration the rotor hub has a reduced external size compared to when it is in the operational configuration. The rotor hub comprises a generally hollow hub body having a first end and a second end spaced along a hub rotational axis, wherein the first end defines a rotor connection flange configured to connect the rotor hub to a main shaft, and wherein a second end defines a nose region of the hub. The hub also defines at least one blade aperture defined between the first end and the second end, a blade bearing associated with the or each blade aperture, and a pitch actuator associated with the blade bearing. In the operational configuration a portion of the pitch actuator protrudes from the nose region of the hub body by a first distance, whereas in the transport configuration the portion of the pitch actuator protrudes from the nose region of the hub body by a lesser extent than when in the operational configuration. Therefore it will be appreciated that the pitch actuator is energised to change the extent to which the pitch actuator protrudes through the nose region of the hub body.

A displacement system for a submersible electrical system such as a tidal turbine system, the displacement system comprising a base for the turbine or related electrical components, a vessel having a buoyant body and at least three rigid legs each displaceable relative to the body between a raised and a lowered position, and in which the base is adapted to be secured to and displaceable by the three legs in order to allow the base to be deployed or retrieved from the seabed using the legs, which legs can also be utilised to raise the body of the vessel out of the water to provide a stable work platform above the deployment site.

A method of installing a wind turbine (10) at an offshore location. The wind turbine (10) includes a tower (18) and an energy generating unit (16). The tower (18) is configured to be secured to a transition piece (12, 42). Prior to shipping, the method includes electrically coupling electrical devices and/or systems (52) by cables (54) to energy generating unit (16) or wind turbine tower (18) or a test dummy therefor. The electrical devices and/or systems (52) are configured to be attached to transition piece (12, 42) once the tower (18) is installed. The method includes testing and commissioning the electrical devices and/or systems (52) while electrically coupled to the cables (54). Prior to shipping and after testing and commissioning, the method includes storing the electrical devices and/or systems (52) and attached cables (54) inside the tower (18). The cables (54) are long enough to permit the electrical devices and/or systems (52) to be attached to the transition piece (12, 42) without disconnecting the electrical devices and/or systems (52) from the cables (54).

A wind turbine cooling system, a wind turbine with the cooling system, and a method for testing the cooling system are provided. The cooling system includes a radiator assembly and a nacelle. The nacelle includes a housing rotatably connected with the radiator assembly. The cooling system is configured to thermally couple the radiator assembly to a heat source inside the nacelle. The radiator assembly is moveable between a first position and a second position. When in the first position, the radiator assembly extends away from an upper roof of the housing of the nacelle. When in the second position, the radiator assembly is contained inside the housing of the nacelle.

The offshore jack-up has a hull and a plurality of moveable legs engageable with the seafloor. The offshore jack-up is arranged to move the legs with respect to the hull to position the hull out of the water. The method comprises moving at least a portion of a vessel underneath the hull of the offshore jack-up or within a cut-out of the hull when the hull is positioned out of the water and the legs engage the seafloor. A stabilizing mechanism mounted on the jack-up is engaged against the vessel. The stabilizing mechanism is pushed down on the vessel to increase the buoyant force acting on the vessel.

A tip bolster (32) for supporting a wind turbine blade (40) on a railcar (14) includes a clamp (360) including first and second clamp arms (364, 366) having first and second jaws (384, 386), respectively, and supporting a pliable saddle (394) extending therebetween, the pliable saddle (394) being configured to support a portion of the blade (40) interposed between the first and second clamp arms (364, 366) and to conform to an exterior surface thereof.

The present invention relates to a wind turbine storage and/or transport system comprising a wind turbine storage and/or transport equipment, and an in-use/not in-use system to be arranged in connection with the wind turbine storage and/or transport equipment, the wind turbine storage and/or transport equipment being configured to support carry the wind turbine component, wherein the in-use/not in-use system comprises one or more detector device(s) being configured to determining a presence of the wind turbine component in or on the wind turbine storage and/or transport equipment.

A wind turbine blade apparatus comprising a root device including: a base having an upper surface with a radius of curvature and configured to receive a root portion of a blade, with housings disposed on lateral sides of the base. The housings including a groove configured to receive a bearing and a shaft extending at least partially through the base and housing. A tip device is also provided which includes a base, a rotatable support frame having: a first support configured to receive a pressure side of a wind turbine blade, a second support configured to receive a suction side of a wind turbine blade, and an opening, the opening configured to receive a portion of a wind turbine blade.

A system is used for lifting a heavy oversized structural element. At least two opposing lifts are placement adjacent opposing sides of the element. Each lift includes a base, a tower, an elevator, and an actuator. The tower extending vertically from the base, and the elevator is disposed on the tower. A support extends from the elevator outward from the tower to engage a point on the element. A guide of the elevator is configured to ride along a rail of the tower. The actuator is connected to the elevator and is configured to move with the elevator vertically along the tower. The actuator can include a strand jack disposed on the elevator. Hydraulic operation of the stand jack moves the jack and elevator along a strand extending along the tower. The arrangements of the lifts leave space below the raised element free for access to other operations.
