There is provided a segmented vacuum jacketed tank system. The system includes a segmented structurally integrated vacuum tank having a vacuum tank main portion between vacuum tank end portions. The vacuum tank main portion includes a vacuum tank skin having an outer surface and an inner surface, vacuum tank skin segments, and a longitudinal cross section with a profile geometry configured for buckling prevention for the vacuum tank skin under external pressure loads. The vacuum tank main portion includes multipurpose stiffener member(s) configured to carry one or more of system transport line(s), a liquid fuel, or a nitrogen gas in an interior. The system includes a pressure tank within the segmented structurally integrated vacuum tank. The pressure tank is configured to store a cryogenic fluid and includes a pressure tank main portion between pressure tank end portions. The system further includes a vacuum cavity.

A storage container includes a wall structure defining an interior, where the interior is configured to contain a fluid. A portion of the wall structure is formed by a composite material. The composite material includes frozen water and a fibrous additive.

There is provided a method for constructing a cylindrical tank, including the step of assembling a metal inner tank by individually and sequentially conducting, on an internal side of a PC wall, raising of an inner tank lateral plate by a jack-up unit and welding of a next-stage inner tank lateral plate onto a lower section of the raised inner tank lateral plate, further including the step of installing a guide pair configured to sandwich the raised inner tank lateral plate onto the next-stage inner tank lateral plate that is to be welded therebeneath. As a result, in the case of adopting the jack-up construction system, it is possible to prevent an inner tank lateral plate from being attached next from falling.
