Barge-carrying ship

摘要

A barge-carrying ship having a crane at the end of the vessel for lifting barges from the water surface, a plurality of openings at the end of the vessel through which the barges are carried aboard the ship, and rails laid in the fore-and-aft direction on the upper deck and along the inner walls of the both sides of the hull for the transportation of the lifted barges to the points where they may be stowed. Barge trucks are provided equipped with low-lift hydraulic jacks for raising and lowering the loads thereon. The barge trucks are distributed at the rate of at least one such truck per track of one or a pair of the rails. Supports protrude inwardly from the inner walls of the both sides of the ship for supporting the barges. The ship has no deck in the hold space except for a middle deck over engine rooms. A second crane is mounted substantially amidships. The ship has stern doors hinged openable to both sides and associated with a plurality of openings at the rear end of the ship in such a manner that, when closed, the doors cover the openings fluidtightly and, when open, they are unmovably secured to the both sides of the ship.
