Abstract: Embodiments herein describe operating a first wind turbine using an auxiliary control system when a high-voltage link coupling a wind park to a grid is not functioning. When using the auxiliary control system, the first wind turbine provides power to a local AC grid which can be used to power auxiliary system in a second wind turbine while the second wind turbine is shutdown. However, when the high-voltage link is functional, the first and second wind turbines provide power to the high-voltage link using a primary control system.

Abstract: A sealing device for a tubing arrangement, preferably for use in an offshore facility, such as an offshore wind turbine or an oil rig. The tubing arrangement has a cable or an inner tube arranged in an interior part thereof. The sealing device comprises a substantially rigid housing and a flexible plug part arranged in an interior part of the housing. The housing is mountable on or forms part of the tubing arrangement in such a manner that the interior part of the housing communicates with the interior part of the tubing arrangement. The flexible plug part comprises an inlet opening connectable to a grout source. When grout material is supplied to the flexible plug part, the flexible plug part expands, thereby providing sealing between the housing and a cable or inner tube arranged in the interior of the tubing arrangement. The sealing device can be mounted on the tubing arrangement before the tubing arrangement is mounted on an offshore facility, and the grout material can be supplied at a later time. Use of divers is thereby minimized. The sealing device can easily be removed and replaced.

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 wind turbine for generating electrical energy may include a tower, a nacelle at the top of the tower, and a rotor coupled to a generator within the nacelle. The wind turbine further includes a cooler including a spoiler and at least one cooler panel projecting above a roof of the nacelle. A heliplatform includes a support structure extending from the nacelle and at least partially integrated with the cooler. The wind turbine may also include a crane coupled to the nacelle and configured to move between a first stowed position underneath the nacelle roof and a second operational position. In the operational position, the crane is selectively positionable over the heliplatform. A method of using the wind turbine and crane is also disclosed.
