Devices and methods for blast/fire containment are disclosed herein. Devices include containers designed to contain and/or mitigate high energy events such as blasts from explosions or thermal runaways. The containers include a body that is built to define an interior chamber shaped to receive an explosive device or a device susceptible to thermal runaway. The container comprises a plurality of substructures that are arranged in a layered sequence to provide the desired effect. The substructures act in concert to decouple the shock load to the main containment structure using shock decoupling with energy dissipation and attenuation technology, having a highly deformable polymer structure, and managed venting. In thermally dominated events, such as a runaway LI battery fire, a crushable medium present in one or more layers of the container presents a significant thermal barrier and contains the fire.

A tank container includes a frame having a front end opposite a rear end that defines a rear plane, a vessel extending between the front end and the rear end of the frame, and a discharge valve assembly. The discharge valve assembly comprises an internal bottom valve, an adaptor, and a discharge valve. The internal bottom valve is positioned within an interior volume of the vessel and the discharge valve is positioned entirely within the frame and offset at least one inch from the rear plane. The adaptor curves downwardly between the internal bottom valve and the discharge valve.

Storage tank comprising—an outer container (2) having a first closable opening (23), and—an inner bladder container (3) disposed within said outer container (2) and having a second closable opening (30), said outer container (2) and inner container (3) being sealed with respect to each other, said inner container (3) being adapted to be filled and or emptied with a liquid through said second closable opening (30), a space (8) between the outer container (2) and the inner container (3) being adapted to be filled with liquid through the first closable opening (23). The outer container (2) is rigid with at least one flexible portion incorporated in the rigid outer container and configured to flex so as to expand and contract to compensate volume variations caused by pressure and or temperature variations to which the storage tank (1) is subjected.

The invention relates to a storage facility for the storage of highly volatile hydrocarbons, comprising at least one vertical round tank (I) which is equipped with a floating cover (5), covering the liquid surface, in the form of a floating roof or a floating ceiling, wherein an annular space (8) formed between the cover (5) and tank wall (3) is sealed by means of flexible sealing elements (9) and wherein fittings (12, 13) for automatic control of overpressures and under pressures in the space (4) under the cover (5) are integrated into the cover (5). The fittings (12, 13) of the at least one round tank (I) are connected to a vapour line (14), the upper end of which is led out of the tank (1) and is in turn connected to a separate vapour expansion tank (15), wherein the round tank (I) and the vapour compensation tank (15) form a closed system.

A subsea tank element comprises at least one tank section (1), the tank section(s) forming a cylindrical concrete-tank (2) closed at its opposite ends by two end caps (12). The tank element further comprises a rectangular structure (3, 4, 5) surrounding the cylindrical tank (2), and a connection (150, 160) between the rectangular structure (3, 4, 5) and the cylindrical tank (2) permitting a motion of the wall of the cylindrical tank (2) within predetermined limits for deflection of the rectangular structure (3, 4, 5). Permanent ballast (6, 7) and a ballast tank (8) control buoyancy and ensure static stability. Post tensioning cables through channels 9 tie the parts into a tank element, and the tank elements into a system. Several applications, including a subsea barge, a subsea hydro-electric plant and a hovering storage tank assembly are disclosed.
