<p>The frame 101, which supports the weight of the nacelle 151 during installation or removal, comprises a guide arranged to align the frame with the substructure 171 as the frame is moved towards the substructure. The guide comprises a pair of guide members 105 arranged on the frame to form a V-shaped void 107 which receives the substructure 171. The guide members 105 may be deformable, or rigid with a protective layer, eg a bumper, or rollers to prevent damage to the substructure. The frame 101 may have a number of cable connectors 109 for connection to cables 111 used to lower, raise and manoeuvre the frame. The frame 101 aids in installation by guiding the turbine nacelle 151 onto the substructure 171 and aids in removal as the guide allows the frame to be guided onto the turbine nacelle prior to lifting away from the substructure. In a modification, the frame (201, figs.14-17) does not support the weight of the nacelle (251) but is instead suspended from the nacelle and may have two pairs of guide members (205).</p> |
