SHIP FOR TRANSPORTING CRYOGENIC MATERIAL

摘要

A ship of simplified construction is adapted for the marine transportation of cryogenic material. At least one single barrier containment tank is located within the hull of the ship. On the inboard side of the inner hull and transverse bulkheads of the ship is provided a thermal insulating system, and covering the inner surface of this insulating system is a gas and liquid impervious liner. A space is provided between the liner and the wall of each containment tank and a cofferdam is provided outboard of the inner hull, outboard of the inner bottom and between the transverse bulkheads. Two circulation systems are provided, the first being provided in the space intermediate the liner and the tank, and the second being provided in the space defined by the cofferdam. Means for the detection of leaks in the containment system are also provided.
