Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.

Abstract: The present invention relates to an assembly of two structural parts of a wind turbine wherein the structural parts are to be connected in a flange-to-flange connection by a number of bolts and such that a flange of the first structural part and a flange of the second are centrally and rotationally aligned whereby a first borehole in the flange of the first structural part is matched and aligned with a corresponding first borehole in the flange of the second structural part. The structural parts may for example be a tower section or a foundation section. The assembly further comprises a first and a second rotational guide member releasably attached to each of the flanges of the structural parts. Each of the rotational guide members comprises a U-shaped or L-shaped structure of a first leg portion and a second leg portion connected by a central portion, the first leg portion ending in a positioning portion shaped to be inserted into a borehole of the flange, and the second leg portion comprising a stop member, and for at least one of the rotational guide members the structure comprised in the rotational guide member is U-shaped. The stop member of the first rotational guide member is configured for abutment to the second leg portion of the second rotational guide member when the flanges of the first and second structural parts are centrally and rotationally aligned. The invention further relates to a method of positioning and connecting two structural parts of a wind turbine as described above. The method includes first centrally aligning the structural parts with the flanges face-to-face and then rotating the structural part relative to each other until the rotational guide members come into contact with each other.

Abstract: The invention relates to a cooling panel assembly (2) for a wind turbine tower (1). It is arranged to be mounted on such a tower (1) on a section thereof as seen in the circumferential direction. The cooling panel assembly (2) includes at least one cooling panel (2a,2b). According to the invention, the cooling panel assembly (2) includes deflector means (6) mounted at the top of the at least one cooling panel (2a, 2b) such that the deflector means (6) shields the cooling panel assembly (2) from above. The deflector means (6) has substantially the same circumferential extension or more as the other parts of the cooling panel assembly (2). The invention also relates to a wind turbine tower (1) provided with at least one such cooling panel assembly (2).

Abstract: A heli-hoist pad that is incorporated into a wind turbine nacelle in a manner that is optimized for helicopter approach and positioning of the heli-hoist pad, such as by being located within a recess in an upper surface of the wind turbine nacelle. Heat exchangers may also be positioned within the free flow of wind outside of a nacelle in manners that provide for serviceability while also allowing for optimal positioning of a heli-hoist pad.

Abstract: The present invention provides a method of installing a foundation for an offshore wind turbine and a template for use herein. In illustrative embodiments, the template is releasably anchored in a seafloor and the template is leveled before installing a pile. In a method according to some illustrative embodiments herein, a template may be provided, the template comprising at least one hollow guiding element for receiving the pile, at least one suction bucket, a frame body to which the at least one hollow guiding element and the at least one suction bucket are coupled, and controlling means configured to supply a pressure to the at least one suction bucket. The method may comprise disposing the template on the seafloor, supplying a negative pressure to the at least one suction bucket for driving the suction bucket in to the seafloor, and controlling the negative pressure supplied to the at least one suction bucket to adjusting a penetration depth of the at least one suction bucket so as to level the frame relative to the seafloor.
