A platform 3 and tower 6 for offshore wind turbines is characterised in that the orientation of the tower with respect to the platform can be adjusted and fixed after the platform has been placed on the seabed 4, thus ensuring that the longitudinal axis 10 of the tower is vertical even where the seabed is not level or flat. The tower may be mounted on a ball and socket joint 1 and positioned in a collar 2 mounted on the platform. Screws or drive rams 7, mounted on the collar, may be used to apply horizontal force on the tower to facilitate the adjustment. The angle of the tower may otherwise be adjusted by means of tensioning guy cables (Fig 4) pulling on the tower.
