[Also in Division F4] In a tanker vessel for the transport of a cargo of liquefied gas at low temperature, the cargo is carried only in containers 5 which are located wholly above the level of the upper deck 3. Smaller auxiliary tanks 6 extend parallel to the fore-and-aft axis of the tanker outboard of containers 5. The sides of the hull 1 are connected by a cladding 7 with the outer walls of the auxiliary tanks and the containers. An insulating layer 8 is arranged between the cladding 7 and the containers and auxiliary tanks. The deck 3 is protected by a second barrier 12 arranged on a load-bearing insulating layer 13. The space between the cladding 7 and the second barrier 12 forms a gas-tight chamber which may be filled with a protective gas.

A tanker for transporting liquefied gases at subatmospheric temperatures and about atmospheric pressure contains at least one liquid-tight thermally insulated hold 13, 14, 15 or 16 with a prismatic storage tank 1 disposed within. The tank 1 is divided into a plurality of liquidtight compartments by walls 20, 21, at least one of which 20 bisects the tank longitudinally. The tank 1 is also provided with a hole in the top communicating with each compartment and with a trunk 5 which houses the vapour, filling and emptying lines. A conduit 29 connects with one of the compartments and with each of others through pipes 27 fitted with valves 26. The compartments may also be connected by valves 23, 24 and 25.
