The present invention relates to containment system for a cryogenic fluid. The system comprises a wall defining an interior space for containing the cryogenic fluid, the wall having an interior surface facing the interior space. the cryogenic fluid comprises liquefied gas At least a portion of the interior surface being provided with a thermal insulation barrier comprising a layer of a material having a contact angle which is at least 150 for the cryogenic fluid.

A triple containment tank includes: a tank foundation; a triple shell including an outer tank, an intermediate tank, and an inner tank; a first anchor strap extending through a first inter-tank region and a second inter-tank region and coupling an inner tank side plate and the tank foundation; and a second anchor strap extending through the second inter-tank region and coupling an intermediate tank side plate and the tank foundation. The first anchor strap includes: a first end portion coupled to the inner tank side plate; a second end portion coupled to the tank foundation; a first intermediate portion located between the first end portion and the second end portion and coupled to an inner wall-side portion of the intermediate tank; and a second intermediate portion located between the first end portion and the second end portion and coupled to an outer wall-side portion of the intermediate tank.

A triple containment tank includes an outer tank, an intermediate tank located in the outer tank, an inner tank located in the intermediate tank and storing a liquefied gas therein, and a pipe penetrating the outer tank, the intermediate tank, and the inner tank. The pipe is coupled to the outer tank through a first expandable pipe, is coupled to one of the inner tank and the intermediate tank through a second expandable pipe, and is joined to the other of the inner tank and the intermediate tank.

Vessels, wall structures, transfer hoses and systems for storing and transferring liquid cryogens are provided and are based on an elastic layer comprised of a polymer fabric impregnated with a cured resin. The elastic layer is substantially impervious to liquid cryogen, for example LNG, and retains elastic properties at typical cryogenic temperatures.

A free-standing liner unit (1) is formed by integrating a planar outer tank liner plate (2), a planar secondary barrier plate (3), and a cold insulator layer (4) that is interposed between the outer tank liner plate (2) and the secondary barrier plate (3) into a single unit. According to this free-standing liner unit (1), when building a tank, it is possible to shorten the construction period by performing the formation of the outer tank shell plates and the formation of the tank internal structure concurrently with each other, and to achieve an improvement in the handleability of the free-standing liner unit (1).
