  • Patent number: 4433940
    Abstract: An improved offshore submarine storage facility in the ocean and like water bodies for storing liquified energy gases and similar liquid materials under pressure and at cryogenic temperatures is disclosed. The facility includes a two-part insulated submarine storage tank positioned at a selected depth in the water for storing said materials, wherein the two parts thereof move in a slidably sealing engagement relative to each other to form an insulated compression storage chamber. The tank also includes ambient water pressure transfer means for transferring external ambient water pressure to the materials stored therein. Mechanical pressure transfer devices increase the pressure applied to the materials stored therein to achieve a total pressure which promotes and aids maintenance of liquid state of the stored cryogenic materials.

  • Patent number: 4402632
    Abstract: Cryogenically cooled and liquified energy gases are stored at substantial depth offshore in an insulated container normally resting on the seabed. Piston action of the container promotes liquid state of the liquified gases by transfer thereto of controlled pressure derived totally or in part from the ambient deep seawater.

  • Patent number: 4365576
    Abstract: Improvements in an offshore platform and submarine storage facility for highly chilled liquified gas, such as liquified natural gas, are disclosed. The improved facility includes an elongated, vertically oriented submerged anchoring frame to which one or more insulated storage tanks are moveably mounted so they can be positioned at a selected depth in the water. The double piston tank is constructed with improved seals to transfer ambient water pressure of the selected depth to the cryogenic liquified gas without intermixture. This transferred pressure at the depth selected aids in maintaining the liquified state of the stored liquified gas. Structural improvements to the tank facilitating ballasting, locking the double piston cylinders together and further facilitating surface access to the tank for inspection, repairs and removal, and structural improvements to the platform are disclosed.
