Abstract (en)
Double sectioned tank for ship's ballast and cargo that can be bult into or placed in the cargo space of a ship (10) to contain ballast water or another liquid without cross-contamination with the cargo residues, i.e. allowing for the carriage of segregated ballast in the cargo space. Allowance is also made for double-bottom space (12) in the ship's loaded condition. A large part (16) of the top, or lid, or the special tank is movable in a vertical direction from the highest part of the tank to the lowest part of the tank and special machinery and safety devices are fitted to expedite this movement. A rubber or flexible fabricà sheet (18), which is watertight, connects the moveable (16) and stationary part (66) of the tank top and divides the tank into an upper (14) and a lower section (12) between which there is no communication. The flexible sheet (18) is designed to take the internal contours of the inner tank when the cargo is loaded.
