<p>A continuous, suitably stiffened skirt is attached by its bottom edge to the top of the double bottom of a ship and beneath the shell or shells which constitute the support for each cargo tank. The top edge of the skirt, which has the same circumference as the bottom edge of the internal one of the shells which form the cargo tank support and is opposite the same, is attached to a suitably stiffened platform, preferably horizontal, which extends between top edge and the inner shell of the ship's hull. Between the skirt and platform, there are a number of flat plates perpendicular to the base plane of the ship and located opposite the double bottom floors and longitudinal girders. These flat plates are welded at their top and inside edges to the platform and skirt, respectively, and at their bottom edge to the top of the double bottom, while at the external edges, those opposite the double bottom floors are welded to the inner shell of the ship's hull, whereas the plates opposite the double bottom longitudinal girders are welded to the skirt of the adjacent tank or to the terminal transverse bulkheads of the cargo tank zone.</p> |
