A storage system is provided that includes a primary container, a first insulation layer, a secondary container, a secondary bottom, and a second insulation layer. The primary container has a primary bottom. The first insulation layer is disposed below the primary bottom. The secondary bottom is disposed below the first insulation layer and the secondary container. The secondary bottom has an expansion joint configured to permit the secondary bottom to expand and/or contract independently from the secondary container. The second insulation layer is disposed below the secondary bottom. In the event of LNG leaking from the primary container, the second insulation layer is protected from LNG contact by the secondary bottom. The carbon steel liner located on the outside face of the concrete wall remains vapor tight and liquid tight in the event of any amount of LNG leaking from the primary container.

The invention is a reservoir for the storage of a pressurized fluid such as compressed air notably to the storage and recovery of energy using compressed air. In particular, the reservoir comprises at least one tube formed of an arrangement of concentric layers (C1, C2, C3, C4). This arrangement comprises, working from the inside toward the outside of the tube, an internal layer (C1) formed of concrete, a layer (C2) formed of steel of thickness E, at least one layer (C3) formed by a winding of steel wires (C3″) on a sublayer (C3′) of concrete, and an external layer (C4) which protects the wires against at least one of physical and chemical damage, and in which the wires are subjected to circumferential (hoop) tensile prestress with at least one of the thickness E and the prestress being rated to withstand the pressure of pressurized fluid.

A prestressed concrete roof for a cylindrical tank is provided with a plurality of prestressed concrete (PC) steel members which are disposed side by side in a circumferential direction at an outer circumferential side of a discoid roof and each of which extends in a radial direction, in which the plurality of PC steel members are made up of both arm parts of folded PC steel members that are folded so as to be open to the outer circumferential side of the roof in a plan view.

A process of fabricating a static structure including an interior volume that includes the steps of mixing coal combustible residual (CCR) with structural reinforcing materials to form a construction material and utilizing the construction material to fabricate exterior enclosure-forming components of the static structure. The enclosure-forming components are sufficiently reinforced, enhanced and/or thick to provide protection against exterior forces directed against the structure.

A method for constructing a double-shell-structured cylindrical tank having an inner tank and an outer tank includes: a step of, inside the outer tank, assembling a first structure of the inner tank excluding a lowermost level of the inner tank by alternately and repeatedly performing raising of an inner tank lateral plate using a jack-up unit and attaching of a next inner tank lateral plate below the raised inner tank lateral plate; a step of assembling a second structure serving as the lowermost level of the inner tank on an annular portion provided on a base portion of the outer tank and configured to support the inner tank; and a step of assembling the inner tank by joining the first structure and the second structure.

A precast, prestressed concrete tank and method that facilitates construction of a primary inner tank within a secondary outer tank, and which permits for the construction of the primary inner tank after the secondary outer tank has been erected, but without requiring insertion through a top of the secondary outer tank, or by tunneling underneath the secondary outer tank, is disclosed. The primary inner tank has an inner wall and the secondary outer tank has an outer wall (precast, prestressed concrete) and wire windings. The primary inner tank is disposed inside of the secondary outer tank. The secondary outer tank has a plurality of first precast outer wall panels, and a temporary construction opening frame. The temporary construction opening frame defines an access doorway during construction of the tank. The temporary construction opening frame is disposed on a foundation base slab.
