摘要

Improvements introduced in the object of the main patent no. 420,576, filed on november 15, 1973, by: "improvements introduced in a ship to transport a plurality of cargo transport barges", according to which said ship comprises: a hull that has a raised bow section to provide floating forward support to said vessel for all drafts thereof, a well cover mounted internally to said hull, extending substantially horizontally parallel to the waterlines of said hull, said bladder being well cover to support said barges in said case, at least one volume of ballast defined within said hull to allow said hull to float to a shallow first draft, when said ballast volume is empty, said volume of ballast being, when it is empty, of a sufficient displacement, with respect to said hull, as to maintain said well cover above it. To the waterline of said vessel with said well cover fully loaded with cargo transport barges, and to a second deeper draft, when said volume of ballast is full of ballast, said well cover being submerged to said second draft to provide flotation of the barges on it, to place said barges on it; means for flooding and emptying said volume of ballast; a bulwark extending upwardly from the bottom of said well deck to a previously selected elevation above said well deck, said bulwark extending from said bow along the port side of said vessel and the starboard side of said vessel, and defining a fixed, unimpeded, open passage through the stern of said vessel for the entrance and exit of cargo transport barges, which extends substantially over the full width of said well deck; having a portion of said bulwark means for establishing communication between the sea surface and the surface of the water contained within said well cover at an elevation above the keel of said selected vessel so that it is partially below the waterline of said vessel, when said volume of ballast is flooded, to allow the entry and exit of water and said well cover, and above the waterline of said vessel, when said volume of ballast is empty, to retard the entrance and exit of water on said bulwark to said well cover and from it.
