ABSTRACT:
An improvement in a barge-carrying flotation-loaded waterborne vessel. A hollow interior defines upper and lower longitudinal barge holds arranged in vertical rows of aligned tiers, each hold being flooded during the time it is loaded and unloaded. There is at least one loading lock at one end of the vessel for enabling flotation loading of each vertical row of barge holds; each lock has a pair of side bulkheads and a bottom, and gate means for separating the lock from and opening it to the outside for flotation loading and unloading of one barge at a time. There is also a separate lock gate for each tier of each row for connecting a hold of each row to a lock. In each lock there are sets of barge support panels, each pivotally attached by a horizontal longitudinally extending pivot to one of the side bulkheads, at least one set being disposed on each side of the lock adjacent to and approximately on a level with each upper longitudinal barge hold. Associated with each set of barge support panels is an erection system for swinging panels up from a vertical storage position to a horizontal barge-supporting position. First locking and releasing means secure each panel in its vertical storage position and release each panel for movement to its load-supporting position. Second locking and releasing means secure each panel in its horizontal barge-supporting position and release each panel to return to its vertical storage position.
