    • A nacelle cover (100) for a wind turbine, wherein the nacelle cover (100) comprises a roof (101), opposite sidewalls (102, 103) and a floor (104) assembled together to form an elongate housing (105) defining an interior space (106) for containing machinery components (125) of the wind turbine, the housing (105) having a front end (107) for mounting to a tower (122) of the wind turbine, an opposite rear end (108), and longitudinally-extending corners (129, 130, 131, 132) of the housing (105). Each of the roof (101), the opposite sidewalls (102, 103) and the floor (104) comprises a respective wall element (114, 115, 116, 117) having opposite longitudinal edges (134, 135) extending between the front and rear ends (107, 108), the longitudinal edges (134, 135) of adjacent wall elements (114, 115, 116, 117) of the housing (105) comprising respective longitudinal flanges (136, 137) which are inwardly inclined relative to the respective wall element (114, 115, 116, 117). At each longitudinally-extending corner (129, 130, 131, 132) of the housing (105) respective adjacent flanges (129, 130, 131, 132) of wall elements (114, 115, 116, 117) comprise an outer flange (136) and an inner flange (137) which are affixed together in an overlapping relationship by a fixing mechanism (140) to form a structural joint (133) along the respective longitudinally-extending corner (129, 130, 131, 132).
