Abstract:
A station for supplying a flammable fluid fuel, the station (1) comprising a first cryogenic tank (2) for storing flammable fuel in the form of a cryogenic liquid, a second cryogenic tank (3) for storing a non-flammable gas and notably an inert gas stored in the form of a cryogenic liquid, a cooling circuit (4, 14) in a heat-exchange relationship with the first tank (2), the cooling circuit (4, 14) comprising an upstream end connected to the second cryogenic tank (3) for drawing cryogenic fluid from the second cryogenic tank (3) in order to give up frigories from the fluid of the second cryogenic tank (3) to the first tank (2), the station comprising a circuit (4, 14, 7) for withdrawing fluid from the second tank (3), characterized in that the station comprises at least a detector (5) of fuel leaks from the first tank (2) and at least a controlled member (6, 11) for opening a portion of the withdrawing circuit (4, 14, 7), the at least one opening member (6) being controlled automatically in response to a detection of a leak by the at least one detector (5) in order to release fluid derived from the second cryogenic tank (3) so as to inert a volume within the station.
Abstract:
Cryogenic fluid storage tank devoid of vacuum insulation and comprising a wall (3) comprising a multilayer structure comprising, from the inside of the tank (1) to the outside of the tank (1): a leaktight first layer (13) comprising one from among a resin reinforced by glass fibers and/or carbon fibers, a polymer such as polyurethane, aluminum, steel, stainless steel, a second layer (23) comprising a thickness of laminated material based on carbon fibers and/or glass fibers, a third layer (33) comprising a thickness of thermal insulation, a fourth layer (43) comprising a thickness of laminated material based on carbon fibers and/or glass fibers, the first layer (13) having a thickness of between 0.1 mm and 6 mm, the second layer (23) having a thickness of between 5 and 40 mm, the third layer (33) having a thickness of between 20 and 200 mm and the fourth layer (43) having a thickness of between 2 and 20 mm.

Abstract:
Cryogenic tank for storing liquefied fluid, having an inner shell delimiting a storage volume for liquefied fluid and an outer shell arranged in a spaced manner around the inner shell, the space between said inner and outer shells having a thermal insulation, a first mechanical connection having a first support wall of truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell, wherein a second mechanical connection has a second support wall of truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell.
Abstract:
A device for storing and transporting liquefied gas, including a first inner reservoir extending in a longitudinal direction, a second outer reservoir, the device having a system for holding the first reservoir in the second reservoir having a first rigid connection between the first reservoir) and the second reservoir at a first longitudinal end, and, at a second longitudinal end of the device, a mechanism for suspending the first reservoir inside the second reservoir having an assembly of tie rods, a first end of the tie rods being attached to a sheath that is secured to the first reservoir via a washer(s) and nut assembly, these being fitted around the tie rod, a second end of the tie rods being attached to a sheath that is secured to the second reservoir via a washer(s) and nut assembly.
Abstract:
Vehicle for delivering inflammable fluid comprising a tractor unit and a tank mounted on a support, the vehicle including a fluid circuit connected to the tank that includes a set of pneumatic valves. The vehicle includes an electrical circuit having at least one electrical component and an electricity source connected to the electrical circuit via at least one port for connecting to a connection interface. A cover moves between a first position blocking access to the connection port(s) to prevent the electrical connection between the electricity source and the electrical circuit and a second position not blocking access to the connection port(s) to enable the electrical connection between the electricity source and the electrical circuit. The vehicle includes a switch connected to the fluid circuit switchable between a first state enabling the operation of the set of pneumatic valves to allow filling or draining and a second state preventing the operation of the set of pneumatic valves to prevent filling or draining. In its first position, the movable cover switches the switch or allows it to is be switched to its first state. When the movable cover is in its second position, the switch is automatically switched to its second state.
