1. A tower section for a wind turbine, wherein the tower section comprises:
a tensioning arrangement located within a radial bounds of the tower section and arranged substantially perpendicular to a central axis of the tower section, the tensioning arrangement comprising one or more tensioning devices attached to three or more attachment points associated with the tower section, wherein the three or more attachment points are located proximate to an end of the tower section,
wherein the one or more tensioning devices are under tension and provide radial stiffness to the tower section, and
wherein the tensioning arrangement is removable from the tower section.
