Abstract: An assembly for a wind turbine, comprising a shaft extending within a main shaft housing. A radially outer portion of the shaft includes at least one engagement formation. A retention mechanism is moveable radially between a radially inward position in which the retention mechanism can engage the at least one engagement formation, such that rotation of the shaft is constrained, and a radially outward position in which the retention mechanism cannot engage the engagement formation, thereby allowing rotation of the shaft.

Abstract: Rotor restraining apparatus (200) and methods for a wind turbine (1) are disclosed. A rotor restraining apparatus has a locking element (204) associated with a rotor (8, 203) of the wind turbine, a rotational axis of said rotor defining an axial direction, the locking element being at least part-circular in form. The locking element comprises a plurality of engagement formations (205) disposed on a periphery thereof. The apparatus also has a restraining member (206), comprising a plurality of engagement formations (207). The restraining member is movable substantially along said axial direction between: (a) a non-restraining position; and (b) a restraining position in which the restraining member engagement formations are able to engage the locking element engagement formations. At least a portion of the restraining member has an arcuate form that substantially matches the curvature (A) of the locking element.

Abstract: A method of replacing a component (28b) of an offshore wind turbine (10) includes providing a sea vessel (30) having a transport system (50)) with a base (52), an elongate platform (54) connected to the base (52), and a transport frame (56a, 56b) for receiving a component (28b) of the wind turbine (10). The sea vessel (30) is positioned such that its deck (40) is separated from the wind turbine (10) by more than a maximum working distance (72) of a crane (26) onboard the wind turbine (10), and further positioned such that in an extended position, the transport frame (56a, 56b) is within the maximum working distance (72) of the crane (26), and in a retracted position, the transport frame (56a, 56b) is outside of the maximum working distance (72). The method includes arranging the transport frame (56a, 56b) in the extended position, lowering a component (28b) of the wind turbine (10) using the crane (26), and placing the component (28b) on the transport frame (56a, 56b). A transport system (50) for handling wind turbine components (28a, 28b) is also disclosed.

Abstract: An assembly (127) for a wind turbine (100) includes a housing (126) having a first bearing (150) and a second bearing (154). A shaft (142) extends axially within the housing (126) and is supported by the first bearing (150) and the second bearing (154) for rotation relative to the housing (126). A radially outer portion of the shaft (142) includes at least one shaft engagement formation (146) positioned between the first bearing (150) and the second bearing (154). A retention mechanism (156) is moveable axially between: an engaged position in which it can engage the shaft engagement formation (146), such that rotation of the shaft (142) is constrained; and a disengaged position in which the retention mechanism (156) cannot engage the shaft engagement formation (146), thereby allowing rotation of the shaft (142). Additionally, a method of operating such an assembly.

Abstract: A nacelle for a wind turbine generator comprises a crane articulated on a base fixed to said nacelle. The crane includes a cantilevered telescopic boom, a principal winch with a lifting line and respective azimuth and elevation drive units for moving said boom in azimuth and in elevation relative to said nacelle. The crane has a deployed condition in which said boom is moveable in azimuth and in elevation and a stowed condition. The nacelle comprises a support structure against which said boom is brought to rest in said stowed condition thereof and wherein when in said stowed condition said boom is located into a predetermined position at which it is held to rest at a point along its length against said support structure and wherein said lifting line is in a reference position in relation to said nacelle when said crane is in its stowed condition. A method for operating a crane in a nacelle comprising operating said crane as a static hoist using a principal winch of said crane when in said stowed condition of said crane.
