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: A method of starting up wind turbine (10) comprises heating first and second components, the first component (32) having a first minimum operating temperature and the second component (42) having a second minimum operating temperature. Heat loss is generated after the second component has been heated to the second minimum operating temperature. The heat loss is transferred to the first component to assist heating the first component to the first minimum operating temperature. The first and second components are cooled after reaching the first and second minimum operating temperatures.
