Abstract: The invention affords a method and apparatus for transporting and erecting an offshore tower. The invention entails a barge which buoyantly supports the tower as it is conveyed to a desired offshore location. Supporting means connected to the barge and sliding means connected to the tower slidingly interconnect the tower and the barge. Suitable rotating means operably associated with the barge serves to rotate the barge about the longitudinal axis thereof to lower one side and thus statically, laterally incline the supporting means and the sliding means relative to the surface of the surrounding water. This occurs once the barge and tower reach the desired offshore location. Translating means operably associated with the barge are afforded for the purpose of moving the tower down the resulting incline, off the lowered side of the barge, and into the surrounding water. In the course of this downward movement, the tower and sliding means move in sliding relation along the supporting means.
