A transportation tooling structure, a split electric motor module with the transportation tooling structure, and a transportation method are provided. The transportation tooling structure comprises: a split base plate, a stator support and a rotor support, wherein the lower end of the stator support is fixedly supported on the upper surface of the split base plate, and the upper end of the stator support is fixedly supported on the side of a split stator close to the split base plate; and the upper end of the rotor support is fixedly supported on the side of an end of a split rotor away from the split stator, and the lower end of the rotor support is fixedly supported on the side of the split stator away from the split base plate.

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 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).
