PCT No. PCT/CA95/00312 Sec. 371 Date Nov. 25, 1997 Sec. 102(e) Date Nov. 25, 1997 PCT Filed May 26, 1995 PCT Pub. No. WO96/37401 PCT Pub. Date Nov. 28, 1996A method of reconstructing a liquid carrying tank vessel, such as an oil tanker, and to the reconstructed vessel whereby a tank vessel constructed with a single bottom hull is reconstructed to a double bottom hull configuration at least over the hull portion including the cargo tanks, and to the reconstructed vessel thereby obtained. The original hull is separated at a point where the bow curve meets the midships section of the hull. A new section is inserted which follows the curvature of the original bows, and increases both the beam and draft. A new double bottom is applied over the remainder of the cargo tank carrying space of the hull, which is tapered in to meet the curve of the stern section. The new section can be fabricated with, or without, a double bottom, depending on its intended use.
