The containers are fastened together, and the assembly is ballasted as appropriate, or required.,下面是Sub-aqueous storage of liquefied gases专利的具体信息内容。

1. A sub-aqueous storage arrangement for liquefied natural gas (LNG), comprising a first closed submersible container, means for transferring LNG to and from the interior of said container, a second submersible container secured to said first container, means providing a fluid connection between said containers, a body of a balancing fluid in said second container and adapted to flow into and out of said first container through said fluid connection, a partitioning means between the LNG in said first container and said balancing fluid, and a partitioning means between the balancing fluid in said second container and the water surrounding both of said containers.
2. Arrangement according to claim 1, wherein the first-mentioned partitioning means comprises a flexible impervious membrane mounted in said first container and physically separating said LNG from said balancing fluid.
3. Arrangement according to claim 1, wherein the second-mentioned partitioning means comprises a flexible impervious membrane mounted in said second container and physically separating said balancing fluid from said water.
4. Arrangement defined in claim 1, wherein said balancing fluid is 2-methyl butane.
5. Arrangement of claim 1, including also a heat-insulating jacket on said first container.
6. Arrangement defined in claim 5, wherein said jacket comprises a porous solid insulating material containing frozen water in its pores.
7. Arrangement according to claim 1, wherein the first-mentioned partitioning means comprises a flexible impervious membrane mounted in said first container and physically separating said LNG from said balancing fluid; and wherein the second-mentioned partitioning means comprises a flexible impervious member mounted in said second container and physically separating said balancing fluid from said water.
8. Arrangement defined in claim 7, wherein said balancing fluid is 2-methyl butane.
9. Arrangement of claim 7, including also a heat-insulating jacket on said first container.
10. Arrangement defined in claim 9, wherein said jacket comprises a porous solid insulating material containing frozen water in its pores.
11. A sub-aqueous storage arrangement for liquefied natural gas (LNG), comprising a first closed submersible container, means for transferring LNG to and from the interior of said container, a second submersible container secured to said first container, means providing a fluid connection between said containers, a body of a balancing fluid in said second container and adapted to flow into and out of said first container through said fluid connection, and a partitioning means between the LNG in said first container and said balancing fluid, the upper portion of said second container being secured to and sealed to said fiRst container but the lower portion of said second container communicating with the water surrounding both of said containers.
