Abstract: A partially submersible wind turbine transport vessel (10) is provided. The vessel includes a port-side wing tank (30) disposed on a port side of the hull (22) and a starboard-side wing tank (28) is disposed on a starboard side of the hull. Both wing tanks (28, 30) are positioned to be above a waterline (WL) of the vessel when the vessel is in a horizontal position, and below a waterline of the vessel when the vessel is in a vertical position. The vessel is configured to rotate, while afloat, about a lateral axis (L) of the hull, altering a pitch of the vessel in such a way as to completely submerge the stern and elevate the bow to a substantially vertical hull position. The floatable wind turbine can then be separated from the vessel and moored.
