The invention provides a tool for moving a drivetrain component in a nacelle of a horizontal axis wind turbine, the nacelle comprising a nacelle structure, the component being connected, in operation of the wind turbine, to a rotor of the wind turbine, the tool comprising at least drive unit for moving the component in relation to the nacelle in a direction parallel to the rotational axis of the rotor, and a plurality of position adjustment devices adapted to be located between the nacelle structure and the component, and distributed so that rotational movement of the component can be provided by coordinated control of the position adjustment devices.

Tool and a method for moving a wind turbine drivetrain component

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.
