    1498778 Liquefied gas storage SENER TECNICA INDUSTRIAL Y NAVAL SA 9 July 1976 [10 July 1975] 28702/76 Heading F4P To collect leakage from an insulated cargo tank 1, a secondary tank 5 is located therebelow and comprises a rigid outer shell 12, an insulation layer 13 and an inner impervious layer 14, pipes 7, 9 leading from the inner surface of the insulation 4 around tank 1 into tank 5 which has means for discharging collected leakage. The discharge means may be an ejector supplied with fluid from the cargo tank 1, a pipe for admitting an inert gas, e.g. nitrogen to vaporize the collected liquid, or as shown in Fig. 5 a heating coil 24 to vaporize the liquid. As shown, the discharge means may be located in a sump 23. The tank may be open-topped with a flexible skirt 10 extending up to the cargo tank 1, which is mounted on an annular support 3, the pipes 7 draining leakage about the support zone and pipe 9 leakage below the zone.

    A self-supporting tank for the transport of cryogenic liquid on ships includes a spherical single-wall cargo shell 1 covered with a layer 2 of thermally insulating material, a peripheral support 3 cargo shell, and a cylindrical container for leakage of cryogenic liquid leak located under the cargo shell 1. A cylindrical container for collecting The cryogenic liquid leakage contains the inner wall 4 of a material that is resistant to low temperatures and is covered with thermal insulation layer 5. The self-supporting tank is equipped with a group of pipelines b, -a. The diameter of the cylindrical tank is made smaller than the diameter of the spherical cargo shell 1 In the layer 2 of the thermally insulating material of the spherical-cargo shell 1 at the level of the large circle plane, perpendicular to the vertical axis 0-0 , a spherical cargo shell 1 passing through the center C, a group of apertures a are associated with the cargo shell 1, and a cylindrical container for collecting leaks of cryogenic liquid contains an outer metal wall 1 adjacent to the layer m 5 thermal insulation. In the internal wall 4, the thermal insulation layer 5 and the outer metal stack 7 of the said cylindrical container there are holes b connected by a group of pipelines b with a group of holes a in the layer 2 of the thermally insulating material of the spherical load shell 1. In the layer 2 of the thermally insulating material in the lower part the spherical shell of the cargo shell 1 is made a hole in, connected through a pipeline 8 with a cavity g of a cylindrical container.
    Self-supporting tank for the transport of cryogenic liquid on ships operates as follows.
    Leaks of cryogenic liquid, resulting from small cracks in the upper hemisphere of the spherical cargo shell 1, flow through the gaps between the outer surface of the cargo shell 1 and the inner surface of the layer 2 of thermally insulating material into the group of holes a made in the layer 2 of thermally insulating material. From the apertures a, the cryogenic liquid leakage then flows through a group of pipelines b and holes b, made in the inner wall 4, thermal insulation layer 5 and the outer metal wall 7 of the cylindrical container, into the cavity of the latter.
    Leakage of cryogenic fluid, formed as a result of
    small cracks in the lower hemisphere of the spherical cargo shell 1, step 1 through 1 through the gaps between the outer. the surface of the cargo shell 1 and the inner surface of the layer 2. thermally insulating material into the hole in, made in the layer 2 of thermally insulating material of the lower part of the spherical cargo shell 1. Then leaks of cryogenic liquid through the pipeline 8 fall into the cavity of a cylindrical container.

    Invention Formula
    Self-supporting tank for the transport of cryogenic liquid on ships including a spherical single-wall cargo shell covered with a layer of thermally insulating material, a peripheral support for the cargo shell, and a cylindrical container for collecting leaks of cryogenic liquid located under the cargo shell and containing an inner wall of low-temperature resistant material. covered with a layer of thermal insulation, distinguished by the fact that, in order to increase reliability in operation and reduce metal consumption, it is equipped with the diameter of the cylindrical container is smaller than the diameter of the spherical cargo shell, while in the layer of thermally insulating material of the spherical cargo shell at the level of the large circle plane, perpendicular to the vertical axis passing through the center of the spherical cargo shell, a group of holes are made, matching a cargo shell, and a cylindrical container for collecting leaks of cryogenic liquid contains an external metal wall adjacent to a layer of thermal insulation, and in An annular cylindrical container is made up of a group of holes passing through the inner wall, thermal insulation layer and outer metal wall. And connected by a group of pipelines with a group of holes in the thermal insulating material layer of a spherical load shell, while in the thermal insulating material layer of the lower part of the said spherical cargo shell a hole is made, connected by a pipeline with a cavity of a cylindrical container.
