A tank for transporting and/or storing a liquefied gas includes: a plurality of walls, each including, in a direction of the thickness of the wall, a thermally insulating barrier and a leak-tight membrane that rests against the thermally insulating barrier and is intended to be in contact with the liquefied gas inside the tank, the thermally insulating barrier including a plurality of self-supporting heat-insulating panels which each includes a block of polymer foam and a plate, a bottom wall of the plurality of walls includes a first portion at least partially surrounding a second portion of the bottom wall, the second portion including drain. The blocks of polymer foam of the second portion have a density greater than a density of the polymer foam blocks of the first portion.

The invention relates to a sealed and thermally insulating tank for storing fluid, comprising, from the outside to the inside of the tank, a secondary thermally insulating barrier and a secondary sealing membrane, the secondary sealing membrane being secured to the secondary thermally insulating barrier, a primary thermally insulating barrier resting against the secondary sealing membrane and a primary sealing membrane resting against the primary thermally insulating barrier, the tank comprising a duct that extends along a longitudinal direction, the duct being delimited on one hand by the secondary thermally insulating barrier and on the other hand by the secondary sealing membrane, a bottom of the duct being at least in part formed by the secondary thermally insulating barrier, the tank further comprising a pressure-drop stopper that is arranged in the duct and extends between the bottom of the duct and the sealing membrane.

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).

An apparatus to refuel a vessel with cryo-compressed hydrogen is disclosed herein. The apparatus includes a refueler controller configured to defuel the vessel prior to a refuel process based on a pressure of the vessel; fill a mixing tank with at least the cryo-compressed hydrogen based on the pressure of the vessel and a pressure of the mixing tank, wherein the mixing tank is connected upstream of the vessel and is structured to include the cryo-compressed hydrogen; initiate the refuel process of the vessel; adjust a temperature of the mixing tank in response to a temperature of the vessel not satisfying a target temperature of the vessel during the refuel process, wherein the temperature of the mixing tank is to be adjusted based on an increase or a decrease of flow of supercritical hydrogen; and end the refuel process in response to the pressure of the vessel satisfying a target pressure of the vessel.

A cryogenic tank comprising an inner container for holding a cryogenic medium, and an outer container surrounding the inner container to define a vacuum space. A pocket extends at least from the vacuum space into an interior space of the inner container. One or more functional components are arranged in the pocket. The one or more functional components include one or more heat exchangers, valves, control components and/or tubes.

A cryogen storage vessel at an installation is filled with liquid cryogen from a liquid cryogen storage tank that has a pressure lower than that of the vessel. After headspaces of the vessel and tank are placed in fluid communication with another via a gas transfer vessel and are pressure-balanced, a pump in a liquid transfer line connected between the tank and the vessel is operated to transfer amounts of liquid cryogen from the tank to the vessel via the liquid transfer line and pump as amounts of gaseous cryogen are transferred, through displacement by the pumped cryogenic liquid, from the vessel to the tank. Following filling, the tank is disconnected and then driven to another location to repeat the filling process with a second vessel that is at a different location.

The invention relates to a pipe penetration module (7) for a cryogenic container (1), which comprises an inner tank (2) and an outer container (3) vacuum-insulated relative to said inner tank, the pipe penetration module (7) comprising a cladding pipe (6) and a pipeline (5) at least partially accommodated in the cladding pipe (6), wherein the pipeline (5) passes with a first pipeline end (10) through a first cladding pipe end (8) of the cladding pipe (6) so that the first pipeline end (10) can be rigidly connected to the outer container (3) and the first cladding pipe end (8) can be rigidly connected to the inner tank (2), the pipeline (5) and the cladding pipe (6) being rigidly connected to one another at a second cladding pipe end (13), and with the pipeline (5) and the cladding pipe (6) each having a kink (17, 18) in an area between the first cladding pipe end (8) and the second cladding pipe end (13).

Leak testing is performed after filling a first tank with pressurized gas and before filling a second tank with the same via a filling circuit including first and second isolation valves. After the first tank is filled, the pressure of gas trapped between the two closed isolation valves is measured. If the pressure is below a predetermined threshold, the first isolation valve is opened until the pressure reaches or exceeds the predetermined threshold, at which time the first isolation valve is closed and the second isolation valve is opened so that the leak test may be performed. If the pressure is otherwise at or above the threshold, the leak test is performed.
