Wind turbine alignment tool

Abstract

A tool (600) for aligning tubular structures (200, 300) of a wind turbine comprises: a plurality of hanger members (601) configured to be pivotably attached to an end region of a first tubular structure (300) so as to extend axially outward therefrom, each of the hanger members comprising a guide part (605) adapted to engage an interior wall (203) of a second tubular structure (200); at least one cable (615) connecting the hanger members (601) together; and a tension mechanism arranged to adjust a tension of the at least one cable (615). The tension mechanism is operable to adjust said tension to pivot the guide parts (605) into engagement with the interior wall (203) of the second tubular structure (200) when the first tubular structure (300) is moved axially toward the second tubular structure (200), thereby to guide the first tubular structure (300) into axial alignment with the second tubular structure (200).
