A nacelle for a wind turbine and a method for erecting a wind turbine are disclosed. The nacelle comprises a main unit arranged to be connected to a wind turbine tower, via a yawing arrangement, and at least one side unit mounted along a side of the main unit in such a manner that direct access is allowed between the main unit and the side unit(s), each side unit accommodating at least one wind turbine component, and at least one side unit being capable of carrying the wind turbine component(s) accommodated therein. The main unit and at least one of the side unit(s) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine. A sufficient interior space of the nacelle is obtained while allowing the nacelle to be transported due to the modular construction. The weight of the wind turbine components is arranged close to the tower due to the transversal arrangement of the side unit(s) relative to the main unit.

Nacelle for a wind turbine, the nacelle comprising side units

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.

Nacelle construction for a wind turbine

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.

Wind turbine having heliplatform arrangement and method of using same

A wind turbine includes a tower having an interior, an exterior, a lower end and an upper end; a nacelle coupled to the tower adjacent the upper end and movable to define at least two yaw positions of the nacelle; a rotor coupled to the nacelle; and an access apparatus disposed about the tower adjacent the upper end thereof, the access apparatus defining a passageway into the nacelle that is exterior of the tower, and the access apparatus providing access to the nacelle in the at least two yaw positions of the nacelle. A method for transporting equipment and personnel to the nacelle using the access apparatus is disclosed. A method for assembling a wind turbine having such an access apparatus is also disclosed.
