Abstract: A tanker ship construction equipped with low temperature liquefied gas tanks having membranous vessels for containing low temperature liquefied gases. The tank is mounted within a hold space prepared in the ship hull. The tank includes an outer box of a steel structure and a heat insulating layer. The outer box has side walls and a bottom adapted to be just strong enough to hold the whole shape thereof for the convenience of the construction and assembly, but not strong enough to support the inner pressure applied by the low temperature liquefied gases loaded in the membranous vessel. The box also has a roof adapted to form by itself a roof portion of the hull, whereby the construction of the tank as well as the assembling thereof into the hull is made substantially easier and the period of construction of the tanker ships is substantially shortened.

Abstract: A storage container constructed either as a tank or a tanker for storage of low-temperature liquids such as liquefied gases. The container is constructed as an outer vessel with a thermal insulation lining and an inner membrane structure consisting of two thin metallic membrane tanks one interiorly of the other. The innermost tank or vessel is thinner than the other inner tank and maintains the fluid-tightness of the container. A vacuum pump applies a vacuum to the space between the two inner tanks to detect leaks and maintains the innermost vessel from collapsing in a non-loaded condition.
