Nacelle cover for a wind turbine

A nacelle cover for a wind turbine, wherein the nacelle cover comprises a roof, opposite sidewalls and a floor assembled together to form a composite material elongate housing defining an interior space for containing machinery components of the wind turbine, the housing having a front end for mounting to a tower of the wind turbine, and an opposite rear end, wherein each of the roof, the opposite sidewalls and the floor comprises a fibre-reinforced polymer composite material, wherein the front end of the housing is mounted on a bed plate frame which is affixed to the tower, the bed plate frame supporting at least one part of a drive train of the wind turbine, and at least one machinery component of said machinery components is mounted on the housing at a position laterally spaced from the bed plate frame in a longitudinal direction along the housing, and the housing comprises a structural tube which is constructed and arranged as a cantilever beam that is vertically displaced by a load of the at least one machinery component mounted thereon, wherein (i) the at least one machinery component is directly mounted on the sidewalls of the housing and the sidewalls of the housing directly support the load of the at least one machinery component, and/or (ii) the at least one machinery component is mounted on a reinforced area of the floor of the housing which is fitted to the sidewalls, a transverse reinforced interior floor of the housing which is fitted to the sidewalls or a transverse support assembly which is fitted to the sidewalls, and thereby the at least one machinery component is indirectly mounted on the sidewalls of the housing, and the sidewalls of the housing indirectly support the load of the at least one machinery component, wherein the opposite sidewalls are provided with a fibre-reinforced polymer composite material reinforcement at opposite regions of the sidewalls at which the front end of the housing is mounted on the bed plate frame, wherein the regions of the sidewalls which comprise the fibre-reinforced polymer composite material reinforcement comprise additional layers of fibrous reinforcement compared to other regions of the sidewalls which do not comprise the fibre-reinforced polymer composite material reinforcement.
