Abstract: An offshore wind turbine generator comprises a tower 1 and a platform 2. The tower 1 is provided with a side door 4 accessed from the platform 2 using a stairway 5 leading to an upper platform 6. The upper platform 6 is formed from the upper surface of a cabinet 7 which houses a diesel backup generator. Both the backup generator and the cabinet 7 are mounted to the tower 1 by bolts, such that the cabinet and backup generator are fully supported by the tower 1. A diesel fuel tank 12 is also mounted to the tower 1 by bolts. The fuel tank supplies diesel fuel to the backup generator.

Abstract: A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

Abstract: A method is provided for handling wind turbine blades aboard a vessel, the method including providing on the vessel a blade rack assembly configured to accommodate more than one blade, the rack assembly having at least a root rack and a tip rack, and the root rack and tip rack defining between them a blade support plane. The method also includes providing a jack acting between the vessel and one of the root or tip rack; and raising or lowering one of the root or tip rack aboard the vessel by the jack to thereby move the blade support plane through an elevation angle θ. A jack assembly on a wind turbine installation vessel and an offshore wind turbine installation vessel are also provided, each capable of raising or lowering a rack of wind turbine blade root or tip support frame elements.

Abstract: A power pack [2] is located within a housing [3] on the platform [1] of a wind turbine generator tower. The power pack [2] is supplied from a fuel tank [4]. With the door [6] of the housing [3] open, the power pack [2] may be removed for servicing and repair by using a U-shaped support structure [8] to which an electric motor [11] is mounted. Two support rails [12] permanently located within the housing [3] support the housed power pack [2]. A chain [15] attached to the power pack [2] is driven by the motor [11] to remove the power pack [2] from the housing [3] by sliding the power pack [2]along the support structure [8]. A pulley arrangement reduces the necessary torque. After removing the power pack [2] from the housing [3], a crane [7] is used to lift the power pack [2] from the platform [1] and to lower it down to a sea vessel [17]. The crane [7] may also be used in the refilling of the fuel tank [4] by hauling a fuel line [18] from a sea vessel up to the platform [1] and connecting it to the fuel tank [4].
