    Abstract: The invention provides a method and apparatus for detecting impairment of the integrity of barriers used for the containment of fluid materials, particularly fluid materials at cryogenic temperatures, e.g., liquefied natural gas. The detection system employs electrical conductors which are in physical relationship to the barrier and undergo a change in current conducting function in the event of barrier failure. In the containment of fluid at low temperatures the detection system preferably comprises conductors which have temperature dependent resistances and are embedded within the thickness of the barrier. By distribution of conductors over different notional zones of the barrier area and provision of associated warning devices the location of leakage points within the barrier area can be automatically indicated.

    Abstract: A storage container for storing substance, particularly liquefied gas, at sub-zero temperatures and atmospheric pressure is provided with a thermally insulating lining incorporating a fluid-impervious primary barrier which forms an integral part of a unitary cellular matrix secured to the structural shell of the container. The matrix cells are occupied by thermally insulating load-bearing material. The unitary cellular matrix sustains the tensile forces imposed due to thermal contraction when the interior of the container is cooled.A method of forming the lining involves the use of thermally insulating blocks individually encapsulated in skins of a synthetic elastomer and the bonding of the blocks together so that their skins are integrated to form a unitary cellular matrix enclosing the insulating blocks.
