Abstract: An externally insulated tanker vessel intended especially for the transport of liquid cargoes at temperatures differing from ambient temperature, including a cargo handling system which utilizes a centralized pumping station located aft of the cargo carrying midbody of the vessel and a piping system within the tanks. Towards this end, all of the electrical and mechanical devices, such as the pumps, valves, and safety interlocks, necessary for the safe loading and discharge of the liquefied cargo are centralized at the pumping station. An inert atmosphere is maintained throughout the pump room although provision is made for aeration to facilitate inspection, maintenance and repair. The piping system is mounted such that movement relative to the hull is permitted to reduce any thermally induced stresses.
