A bladder-type multipurpose vessel which provides a novel solution to the problems that exist in current oil tankers, such as unsafety, unitary transportation function and environmental pollution. The cargo hold of the present vessel is of the construction combined by a rigid structure and a flexible one, and the crude oil lies in a quad protection of an outer shell, an inner shell, a water cushion and spray layer, and a bladder, causing its safety to be greatly increased. Since the vessel has the special cargo hold construction and corresponding facilities to make it possible to transport both oil and water as well as goods, being of outstanding applicability, economy, safety and environmental protection effect.

[ What is claimed is:] [1.] A bladder-type multipurpose vessel operable to transport oil, water, or solid cargo, the vessel comprising:an outer shell;a deck fitted substantially to said outer shell;an inner shell substantially spaced apart from said outer shell such that a space for holding water is defined therebetween, said space defining a water cushion, said inner shell including a floor and a pair of opposed side walls;a hold defined within said deck and said inner shell;an automatic valve operatively associated with said inner shell for permitting the selective flow of fluids between said water cushion space and said hold;a charging and discharging port for controlling the flow of water into said water cushion space;a flexible, oil-holding bladder disposed within said hold;an oil receiving port fitted to said deck for permitting fluid communication of oil into and out of said bladder; andmeans for selectively lifting said bladder off of said floor and at least partially away from said pair of opposed side walls.
