Abstract: A nacelle bottom cover part (32) for the underside of a wind turbine nacelle is formed with a number of shallow receptacle regions for containing liquid leaked or spilled from turbine components. Overflow channels (88,90,92) may be provided between the receptacle regions so that leaked liquid can flow between receptacle regions.

Abstract: A wind turbine has a nacelle which houses operative components such as a transformer or converter which in use generate unwanted heat, the nacelle including an external nacelle cover (20) to form the outer nacelle enclosure, and provided with a panel (24) which overlies a bottom cover (22) region forming therewith a conduit for directing external air to one or more of the heat generating operative components for cooling purposes.

Abstract: A nacelle for a wind turbine, the nacelle comprising a roof panel forming an opening into an internal space; a cooling arrangement extending upwards from the roof panel; and a closure movable between an open position revealing the opening and a closed position closing the opening. To enable easy parking of the closure and particularly to enable parking of the closure in a position where it does not occupy a large surface space on the roof panel, the nacelle further comprises a track configured to guide the closure between the open and the closed positions, the track being carried at least partly by the cooling arrangement.
