The portion of the turbine that encompasses the drive train, the bedplate on which it rests and the cover that protects the components from the elements. The nacelle for offshore turbines is specially designed to seal the interior from salt spray and moisture. The nacelle also includes maintenance cranes, access hatches and wind sensors.
The rotor attaches to the nacelle, which sits on top of the tower and includes the gear box, main and small shafts, generator and brake. A cover protects the components inside the nacelle. Some nacelles are large enough for a technician to stand inside while working.
