The invention relates to a device (100), a system (10) and a method for modifying the cross section of a tower section (1) of a wind turbine, wherein the tower section comprises a flange (4) located at an end (3) of the tower section having a plurality of through holes (5) spaced around its circumference for securing said tower section to another wind turbine section. The method comprises securing tensioning mechanism (14) to each of a pair of said plurality of through holes in the flange of the tower section, said pair of holes being generally opposed; and applying a tensile force between said pair of holes in the flange of the tower section. La présente invention concerne un dispositif (100), un système (10) et un procédé de modification de la section transversale d'une section tour (1) d'une éolienne, la section tour comprenant une bride (4) située à une extrémité (3) de la section tour ayant une pluralité de trous traversants (5) disposés à distance les uns des autres autour de sa circonférence pour fixer ladite section tour à une autre section turbine éolienne. Le procédé comprend les étapes consistant à fixer un mécanisme de tension (14) à chacun d'une paire de ladite pluralité de trous traversants dans la bride de la section tour, ladite paire de trous étant généralement opposée ; et appliquer une force de traction entre ladite paire de trous dans la bride de la section tour.
