Method for assembling and installing a liquefied gas storage tank.

The invention relates to a liquefied gas storage installation comprising a load-bearing structure and a sealed and thermally insulating tank (71) arranged in the load-bearing structure, in which the so-called adjacent membranes (13, 13′) of the sealing membrane of the cofferdam wall of the main structure of the tank (71) protrude at least partially into the liquid dome (2), said so-called contiguous membranes being directly sealably fastened to the so-called adjacent membranes of the liquid dome (2).

The invention relates to a rechargeable battery transportation device (10) for a re-chargeable battery (22), in particular a lithium rechargeable battery, with (a) an external case (12) which has (i) a base body (16) with a filling opening (20), (ii) a cap (18) for creating an air-tight seal of the filling opening (20), and (iii) a ventilation opening (28), and (b) an inner tank (14) which (i) is arranged in the external case (12) and (ii) encloses an accommodation space (30) for accommodating the rechargeable battery (22). According to the invention, between the external case (12) and the inner tank (14) there is at least one flow path (S) from the accommodation space (30) to the ventilation opening (28), and a heat absorption material (36) is arranged along the flow path (S).

A system for storing fuel includes a support structure supporting at least one fuel tank a predetermined distance above ground. The fuel tank includes an inner tank configured to contain a gaseous fuel, an intermediate tank encompassing the inner tank and defining a first annular space therebetween, and an outer tank encompassing the intermediate tank an defining a second annular space therebetween. The first annular space is filled with a shock-absorbing resin for absorbing structural stresses, while the second annular space is filled with an insulating material providing for fire and ballistic resistance. The intermediate tank is connected to the support structure and to at least one adjacent fuel tank, and prevents the transfer of load to the inner tank.

An installation for storing and transporting a cryogenic fluid on a ship includes: a sealed and thermally insulating tank, having a ceiling wall including, from the outside to the inside, a primary thermally insulating barrier and a primary sealing membrane intended to be in contact with the cryogenic fluid; and a sealed line penetrating through the ceiling wall of the tank, the line including a bottom portion of which a first end is situated inside the ceiling wall of the tank and a second end is situated outside the ceiling wall of the tank in a thicknesswise direction of the ceiling wall, and a top portion fixed to the second end of the bottom portion. The bottom portion includes an alloy with low thermal expansion coefficient. The primary sealing membrane is tightly fixed to the bottom portion of the line around the line.

A method is described for checking the sealing of a sealed and thermally insulating tank for storing a liquefied gas at low temperature. The tank has a primary space and a secondary space where, in order to perform the check, a difference in pressure is created between the two spaces at least some of the inert gas injected into the primary space is recovered via at least one secondary outlet of the secondary space so as to be reinjected into the primary space.

The present invention relates to containers and packaging materials, and more particularly to a container having a thermal barrier member for reducing the transfer of heat from and/or to the container. The shipping container preferably comprises an outer vessel with an O-ring and an inner vessel separated by an air gap. The inner vessel has a first and second wall and a lid assembly. The lid assembly has a top lid and a bottom lid and a thermal paste. A felt gasket is preferably positioned between the lid assembly and the first and second walls. The first and second walls comprise at least two relief valves. One relief valve is a Flame Arresting/Smoke Particulate Filtration/Chemical Adsorption Unit Assembly and the valve is bi-directional. The thermal paste is preferably a flowable polymer based heat-absorbing material. The shipping container is stackable on a registration plate with other containers.

The invention relates to a fluid storage facility, the storage facility comprising a supporting structure (1) and a tank, the tank having at least one tank bottom wall fixed to the supporting structure (1), wherein the bottom wall has a structure with multiple layers superimposed in a direction of thickness, including at least one sealing membrane and at least one thermal insulation barrier arranged between the sealing membrane and the supporting structure (1),

wherein the bottom wall has a sump structure (9) having a rigid container (10, 11) comprising a side wall (12), the container (10, 11) being arranged through the thickness of the bottom wall, and the sump structure (9) comprising at least one fixing means (15) designed to fix the rigid container (11) to the supporting structure (1) at a fixing point,
and wherein the at least one fixing means (15) is configured to allow the relative movement of the side wall (12) of the container (11) with respect to the supporting structure (1) in a transverse direction perpendicular to the side wall (12) at the fixing point of the container (11).

A sealed and thermally insulating storage tank for a fluid that is anchored in a load-bearing structure built into a ship, the ship having a longitudinal direction, the tank having a loading/unloading tower suspended from a ceiling wall of the load-bearing structure, the loading/unloading tower including first, second and third vertical pylons defining a prism of triangular section, the loading/unloading tower carrying at least a first pump, the tank having a support foot that is fastened to the load-bearing structure, the tank having at least one sump, the first pump being arranged outside the triangular prism and being aligned with the support foot in a first transverse plane that is orthogonal to the longitudinal direction of the ship.

A sealed and thermally insulating tank for storing a fluid, the tank being anchored in a load-bearing structure, the tank having a loading/unloading tower suspended from a ceiling wall of the load-bearing structure, the tank having a support foot that is fastened to the load-bearing structure in a zone of a bottom wall of the tank, the support foot being arranged to guide a vertical translational movement of the loading/unloading tower, the tank having at least one sump that is formed in the bottom wall of the tank, the bottom wall of the tank having a corrugated sealing membrane that is intended to be in contact with the fluid having at least first corrugations extending in a first direction and spaced apart from one another, the sump and the support foot are spaced apart by a distance at least three first corrugations pass between the sump and the support foot.

The present invention provides a control device that includes a first temperature detection unit that detects a partition wall temperature of a tank main body in which liquefied gas is contained, and a second temperature detection unit that detects a temperature of a skirt that supports the tank main body. The control device further includes a temperature difference acquisition unit that acquires a temperature difference between the partition wall temperature detected by the first temperature detection unit and the temperature of the skirt which is detected by the second temperature detection unit, and a determination unit that determines whether or not a joint between the tank main body and the skirt is rapidly cooled by the liquefied gas on the basis of the partition wall temperature and the temperature difference.
