Definitions

  • the invention relates to a container for storing and transporting liquefied gas.
  • a container for storing and transporting liquefied gas is known from WO2017190846 A1 .
  • the invention relates more particularly to a container for storing and transporting liquefied gas, in particular cryogenic fluid such as helium, comprising a first internal tank extending in a longitudinal direction and intended to store the liquefied gas, a second external tank disposed around the first tank with vacuum insulated spacing between the first and second tanks, the container comprising a third annular tank disposed around the first tank, between the first and second tanks, the third annular tank extending around of at least part of the first tank and containing a liquefied gas to form a heat shield ensuring thermal insulation of the first tank, the container comprising a device for holding the first and third tanks in the second tank, the holding system being configured to allow limited movement of the first and third tanks in the second tank in particular in the longitudinal direction during their dimensional variations due to temperature variations, the holding system comprising a set of tie rods.
  • cryogenic fluid such as helium
  • the transport of liquefied gas, particularly helium, generally uses vacuum-insulated containers or “iso-containers”.
  • cryogenic storage has excellent thermal performance.
  • the heat input of a cryogenic container with a capacity of 41,0001 must be of the order of 4.5W for example.
  • the enthalpy of vaporization maintains the screen temperature at approximately -196°C.
  • the nitrogen thus vaporized is evacuated to the atmosphere through piping to maintain the nitrogen guard at low pressure typically 0.5 bar. Liquid nitrogen is thus “consumed” during transport.
  • the nitrogen tank is sized by the consumption per unit of time and the maximum duration of transport.
  • the autonomy of the container is dependent on this nitrogen reserve. Increasing this nitrogen reserve increases the autonomy (the duration during which insulation is guaranteed) but reduces the amount of space available for the interior tank which stores the helium.
  • the nitrogen tank is typically 1200 liters. To achieve a transport life of 75 days, the nitrogen capacity must be more than 3,000 liters.
  • An aim of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
  • the container according to the invention is essentially characterized in that at least part of the tie rods have a first end connected in an articulated manner to the second tank and a second end rigidly connected to the first tank or to the third tank or to a structural part rigidly linked to the latter, said articulated tie rods being movable between two determined angular positions respectively defining two distinct positions of the second end of the tie rods and corresponding respectively to the extremes of the dimensional variations of the first and third tanks relative to the second tank.
  • the invention may also relate to any alternative device or method comprising any combination of the characteristics above or below within the scope of the claims.
  • the container 1 for storing and transporting liquefied gas, in particular cryogenic fluid such as helium, illustrated in the figures preferably has a general cylindrical shape which is understood in a longitudinal direction A which is horizontal in the position of use.
  • This container 1 comprises a first internal tank 2, preferably of generally cylindrical shape, which extends in the longitudinal direction A.
  • This first tank 2 or internal tank, is intended to store liquefied gas (helium or other cryogenic liquid/gas mixture).
  • the walls of the first tank 2 are for example made of a metallic material, for example austenitic stainless steel or any other suitable material.
  • the container 1 comprises a second tank 3, or "external" envelope arranged around the first tank 1 with a vacuum insulated spacing between the first 2 and the second 3 tank (and one or more layers of insulating material).
  • the second tank 3 is for example of generally cylindrical shape and can be concentric around the first tank 1.
  • the walls of the second tank 3 are for example made of a metallic material, for example austenitic steel or stainless steel or any other suitable material.
  • the container 1 comprises a third tank 4 arranged around the first 2 tank, between the first 2 and the second 3 tank.
  • the third tank 4 (for example annular in section perpendicular to the longitudinal direction A) and extends around at least part of the first tank 2 in the longitudinal direction A.
  • this third tank 4 has a cylindrical shape and can be arranged concentrically around the first tank 2.
  • This third tank 4 or intermediate tank is intended to contain a liquefied gas, for example nitrogen, to form a heat shield ensuring thermal insulation of the first 2 tank.
  • the third tank 4 may comprise or be made up of two concentric cylindrical shells spaced apart (different diameters) and connected and closed at their ends by partitions. These two cylindrical walls thus form an annular capacity having the dual function of storing liquid nitrogen and providing a heat shield for the first tank 2.
  • the volume thus created can be 3100 liters for an ISO counter of 40 feet (approximately 12 meters).
  • the container 1 further comprises one or more screen walls 11, 12 thermally connected to the third 4 tank and arranged at the ends of the tank between the first 2 and the second 3 tank.
  • These walls 11, 12 form covers at the ends or bottoms of the tank to close the screen around the first tank 2.
  • These plates are “thermalized” (i.e. i.e. cooled) by the third tank 4.
  • the container 1 includes a device for holding the first 2 and third 4 tanks in the second tank 3.
  • the holding system provides support/suspension of the first 2 and third 4 tanks in the second tank 3.
  • This holding system is configured to allow limited movement of the first 2 and third 4 tanks in the second tank 3 in particular according to the direction longitudinal A during their dimensional variations (expansions/retractions depending on the hot or cold states).
  • the holding system comprises a set of tie rods 5, 6 of which at least part have a first end 7 articulatedly connected to the second 3 tank and a second end 8, 9 rigidly connected to the first tank 2 or to the third tank 4 (or to a structural part rigidly linked to the latter).
  • the articulated tie rods 5, 6 are movable between two determined angular positions respectively defining two distinct positions of the second end 8, 9 of the tie rods. These two positions correspond respectively to the extremes of the dimensional variations, in particular longitudinal, of the first 2 and third 4 tanks relative to the second tank 3.
  • the container 1 may comprise a fixed and rigid connection 15 between, on the one hand, a longitudinal end of the second tank 3 and, on the other hand, the adjacent longitudinal end of the first tank 2 and one end of the third tank 4 or a support element integral with the latter. That is to say that the fixed and rigid connection 15 blocks the longitudinal movement of one longitudinal end of the first 2 and the third 4 tank relative to the second tank 3 while allowing longitudinal movement of the opposite end of the first 2 and third 4 tank relative to the second tank 3.
  • the articulated tie rods 5, 6 are preferably located at the other end (opposite the fixed connection 15) which has a minus this longitudinal degree of freedom.
  • the holding system may comprise a first set of tie rods 5, having a first end 7 connected to the second tank 3 and a second end 8 rigidly connected to the first tank 2.
  • This first set of tie rods 5 comprises a plurality of tie rods 5, in particular four tie rods 5 whose first end 7 is located at a first longitudinal end of the second tank 3 (for example the left end on the figure 1 ), the second end 8 of the tie rods 5 is connected to a first longitudinal end of the first tank 2 (left end on the figure 1 ).
  • the first set of tie rods 5 may comprise two upper tie rods 5 having their first end 7 connected to the upper part of the second tank 3 and their second end 8 connected to the lower part of the first tank 2.
  • the other tie rods 5 lower parts can have their first end 7 connected to the lower part of the second tank 3 and their second end 8 connected to the upper part of the first tank 2.
  • the upper and lower parts can be defined according to whether they are above or below the central longitudinal axis A of the tank 2 or the container 1.
  • the lower tie rods 5 have their second end 8 connected to the lower or central part of the first tank 2 and the upper tie rods 5 have their second end 8 connected to the upper or central part of the first tank 2.
  • the second tank 3 preferably has a general cylindrical shape extending in the longitudinal direction A with a determined radius of, for example, between 90 and 121.9 cm.
  • the tie rods 5 of the first set of tie rods, respectively of the second set of tie rods have a length preferably between 80 and 150% and preferably between 90 and 130% of the length of said radius.
  • the upper tie rods 5 intersect with the tie rods 5 lower (in a plane parallel to the longitudinal direction).
  • the second ends 8 of the tie rods 5 can be housed in tubes 18 or metal sheaths to ensure the connection to the first tank 2 by extending the thermal path. That is to say that each tube 18 is fixed (welded for example) to the first tank 2 but the fixing of the second end 8 of the tie rod 5 to its tube 18 is offset relative to the fixing between the tube and the tank 2 to lengthen the thermal path.
  • each tie rod 5 is bolted (or fixed in any other appropriate way) to a sheath or any which is itself welded (or other) to the first tank 2.
  • these second ends 8 of the tie rods 5 can be fixed to a ring or crown secured to the end of the first tank 1.
  • the upper tie rods 5 can cross at an angle B between 70 and 130 degrees and preferably between 90 and 120 degrees.
  • the lower tie rods 5 can intersect at an angle between 70 and 130 degrees and preferably between 90 and 120 degrees. See also the Figure 4 .
  • this first set of tie rods 5 is not articulated or weakly articulated to ensure fixed maintenance (or a low tolerance of movement) of the first end of the first tank 2 relative to the second tank 3 (particularly in the case of the fixed connection 15).
  • the container 1 comprises a second set of tie rods 5 of the same nature as the first set at the level of the other longitudinal end of container 1 (on the right on the figure 1 ).
  • These tie rods 5 of the second set have a first end 7 connected to the second tank 3 and a second end 8 rigidly connected to the first tank 2.
  • This second set of tie rods comprises a plurality of tie rods 5, in particular four tie rods 5 whose first end 7 is located at the second longitudinal end of the second tank 3.
  • the second end 8 of the tie rods 5 is connected to the second longitudinal end of the first tank 2 (as previously preferably via a ring or tube secured to the end of the first tank 2.
  • the tie rods of the second set of tie rods 5 can be arranged like those of the first set (cf. figure 2 Or 4 and description above).
  • the second ends 8 of the tie rods 5 can be connected to the first tank 2 or to a neck fixed to the latter.
  • the ends 7 of the tie rods 5 of the second assembly are articulated to allow in particular movement of the second end of the first tank 2 in the longitudinal direction (cf. figure 1 the retracted position in dotted lines).
  • the container 1 comprises a third set of tie rods 6, in particular four tie rods 6 having a first end 10 connected to the second tank 3 and a second end 9 connected to the third tank 4 via a support 11, 12, 13 rigidly connected to the latter.
  • the first end 10 of the tie rods 6 of the third set is located at the first longitudinal end of the second tank 3.
  • the second end 9 of said tie rods 6 being located at the level of the first longitudinal end of the container 1.
  • the third set of tie rods 6 preferably comprises two upper tie rods 6 whose first end 10 is located in the upper part of the second tank 3 and the second end 9 is located in the upper part of the first tank 2 (cf. figures 3 And 4 ).
  • the two lower tie rods 6 preferably have the first end 10 connected to the lower part of the second tank 3 and the second end 9 located in the lower part of the first tank 2.
  • the two upper tie rods 6 are oriented relatively with an angle of between 60 and 110 degrees and preferably between 70 and 90 degrees and the two lower tie rods 6 are oriented relatively with an angle of between 60 and 110 degrees and preferably between 60 and 90 degrees.
  • Container 1 includes a fourth set of tie rods 6 at the other end of container 1 which can be arranged in the same configuration as the third set (see above and figures 3 And 4 ).
  • the tie rods 6 of the third set of tie rods, respectively of the fourth set of tie rods, have a length of between 30 and 80% and preferably between 40 and 60% of the length of the radius of the section of the second tank 2.
  • the two internal tanks 2, 4 are carried and suspended in the first external tank 1 via tie rods 5, 6 located at the two ends of the container 1.
  • the second ends of the tie rods 6 supporting the third tank 4 can be connected to rings 13 or plates secured to the third tank 4 via the screen walls 11, 12.

Description

L'invention concerne un conteneur de stockage et de transport de gaz liquéfié. Un tel réservoir est connu de WO2017190846 A1 .The invention relates to a container for storing and transporting liquefied gas. Such a reservoir is known from WO2017190846 A1 .

L'invention concerne plus particulièrement un conteneur de stockage et de transport de gaz liquéfié, notamment de fluide cryogénique tel que de l'hélium, comprenant un premier réservoir interne s'étendant selon une direction longitudinale et destiné à stocker le gaz liquéfié, un second réservoir externe disposé autour du premier réservoir avec un espacement isolé sous vide entre le premier et le second réservoir, le conteneur comprenant un troisième réservoir annulaire disposé autour du premier réservoir, entre le premier et le second réservoir, le troisième réservoir annulaire s'étendant autour d'au moins une partie du premier réservoir et contenant un gaz liquéfié pour former un écran thermique assurant un isolation thermique du premier réservoir, le conteneur comprenant un dispositif de maintien des premier et troisième réservoir dans le second réservoir, le système de maintien étant configuré pour permette un débattement limité des premier et troisième réservoirs dans le second réservoir notamment selon la direction longitudinale lors de leurs variations dimensionnelles dues à des variations de température, le système de maintien comprenant un ensemble de tirants.The invention relates more particularly to a container for storing and transporting liquefied gas, in particular cryogenic fluid such as helium, comprising a first internal tank extending in a longitudinal direction and intended to store the liquefied gas, a second external tank disposed around the first tank with vacuum insulated spacing between the first and second tanks, the container comprising a third annular tank disposed around the first tank, between the first and second tanks, the third annular tank extending around of at least part of the first tank and containing a liquefied gas to form a heat shield ensuring thermal insulation of the first tank, the container comprising a device for holding the first and third tanks in the second tank, the holding system being configured to allow limited movement of the first and third tanks in the second tank in particular in the longitudinal direction during their dimensional variations due to temperature variations, the holding system comprising a set of tie rods.

Le transport de gaz liquéfié, notamment d'hélium, utilise généralement des conteneurs ou « iso conteneurs » isolés sous vide.The transport of liquefied gas, particularly helium, generally uses vacuum-insulated containers or “iso-containers”.

En effet, le transport d'hélium liquide sur de grande distance n'est possible que si le stockage cryogénique a d'excellentes performances thermiques. Les entrées de chaleur d'un container cryogénique d'une capacité de 41 0001 doit être de l'ordre de 4.5W par exemple.Indeed, the transport of liquid helium over long distances is only possible if the cryogenic storage has excellent thermal performance. The heat input of a cryogenic container with a capacity of 41,0001 must be of the order of 4.5W for example.

Le rayonnement représente la contribution la plus importante des entrées de chaleur. Pour atteindre ces performances, il est nécessaire de protéger le réservoir d'hélium liquide du rayonnement par un écran thermique actif (aluminium ou cuivre par exemple) refroidi par exemple par de l'azote liquide. Cf. par exemple US5005362 .Radiation represents the most important contribution of heat input. To achieve these performances, it is necessary to protect the liquid helium tank from radiation by an active thermal shield (aluminum or copper for example) cooled for example by liquid nitrogen. See for example US5005362 .

Le flux du rayonnement vaporise lentement l'azote. L'enthalpie de vaporisation maintient à environ -196°C la température de l'écran. L'azote ainsi vaporisée est évacué à l'atmosphère par une tuyauterie pour maintenir la garde azote à basse pression typiquement 0.5bar. L'azote liquide est ainsi "consommé" pendant la durée du transport. Le réservoir d'azote est dimensionné par la consommation par unité de temps et la durée maximum du transport.The radiation flow slowly vaporizes the nitrogen. The enthalpy of vaporization maintains the screen temperature at approximately -196°C. The nitrogen thus vaporized is evacuated to the atmosphere through piping to maintain the nitrogen guard at low pressure typically 0.5 bar. Liquid nitrogen is thus “consumed” during transport. The nitrogen tank is sized by the consumption per unit of time and the maximum duration of transport.

L'autonomie du conteneur est dépendante de cette réserve d'azote. L'augmentation de cette réserve d'azote augmente l'autonomie (la durée durant laquelle l'isolation est garantie) mais réduit la quantité d'espace disponible pour le réservoir intérieur qui stocke l'hélium. Pour une durée de transport de 45 jours, le réservoir d'azote est typiquement 1200 litres. Pour atteindre une durée de transport de de 75 jours, la capacité d'azote doit être de plus de 3 000 litres.The autonomy of the container is dependent on this nitrogen reserve. Increasing this nitrogen reserve increases the autonomy (the duration during which insulation is guaranteed) but reduces the amount of space available for the interior tank which stores the helium. For a transport duration of 45 days, the nitrogen tank is typically 1200 liters. To achieve a transport life of 75 days, the nitrogen capacity must be more than 3,000 liters.

De plus, l'agencement structurel de ces éléments (dont la tuyauterie) dans l'enveloppe externe doit pouvoir supporter des efforts lors du transport ou des variations dimensionnelles relatives entre l'enveloppe extérieure et les réservoirs de stockage interne (état froid rempli de fluide cryogénique ou état chaud à la température ambiante).In addition, the structural arrangement of these elements (including the piping) in the external envelope must be able to withstand forces during transport or relative dimensional variations between the external envelope and the internal storage tanks (cold state filled with fluid cryogenic or warm state at room temperature).

Le document US2863297 décrit un réservoir comprenant une réserve de fluide interposée entre les parois extérieure et intérieure.The document US2863297 describes a reservoir comprising a reserve of fluid interposed between the exterior and interior walls.

Le conteneur 1 de stockage et transport de gaz liquéfié, notamment de fluide cryogénique tel que de l'hélium, illustré aux figures a de préférence une forme générale cylindrique qui s'entend selon une direction longitudinale A qui est horizontale en position d'utilisation.The container 1 for storing and transporting liquefied gas, in particular cryogenic fluid such as helium, illustrated in the figures preferably has a general cylindrical shape which is understood in a longitudinal direction A which is horizontal in the position of use.

Ce conteneur 1 comprend un premier réservoir 2 interne, de préférence de forme générale cylindrique, qui s'étend selon la direction A longitudinale.This container 1 comprises a first internal tank 2, preferably of generally cylindrical shape, which extends in the longitudinal direction A.

Ce premier réservoir 2, ou réservoir interne, est destiné à stocker le gaz liquéfié (hélium ou autre mélange liquide/gaz cryogénique).This first tank 2, or internal tank, is intended to store liquefied gas (helium or other cryogenic liquid/gas mixture).

Les parois du premier réservoir 2 sont par exemple constituées d'un matériau métallique, par exemple un acier inoxydable austénitique ou tout autre matériau approprié.The walls of the first tank 2 are for example made of a metallic material, for example austenitic stainless steel or any other suitable material.

Le conteneur 1 comprend un second réservoir 3, ou enveloppe « externe » disposée autour du premier réservoir 1 avec un espacement isolé sous vide entre le premier 2 et le second 3 réservoir (et une ou des couches de matériau isolant) .The container 1 comprises a second tank 3, or "external" envelope arranged around the first tank 1 with a vacuum insulated spacing between the first 2 and the second 3 tank (and one or more layers of insulating material).

Le second réservoir 3 est par exemple de forme générale cylindrique et peut être concentrique autour du premier réservoir 1.The second tank 3 is for example of generally cylindrical shape and can be concentric around the first tank 1.

Les parois du second réservoir 3 sont par exemple constituées d'un matériau métallique, par exemple un acier ou acier inoxydable austénitique ou tout autre matériau approprié.The walls of the second tank 3 are for example made of a metallic material, for example austenitic steel or stainless steel or any other suitable material.

Le conteneur 1 comprend un troisième réservoir 4 disposé autour du premier 2 réservoir, entre le premier 2 et le second 3 réservoir.The container 1 comprises a third tank 4 arranged around the first 2 tank, between the first 2 and the second 3 tank.

Le troisième réservoir 4 (par exemple annulaire en coupe perpendiculaire à la direction longitudinale A) et s'étend autour d'au moins une partie du premier 2 réservoir selon la direction longitudinale A. De préférence, ce troisième réservoir 4 a une forme cylindrique et peut être disposés concentriquement autour du premier réservoir 2. Ce troisième réservoir 4 ou réservoir intermédiaire est destiné à contenir un gaz liquéfié, par exemple de l'azote, pour former un écran thermique assurant une isolation thermique du premier 2 réservoir.The third tank 4 (for example annular in section perpendicular to the longitudinal direction A) and extends around at least part of the first tank 2 in the longitudinal direction A. Preferably, this third tank 4 has a cylindrical shape and can be arranged concentrically around the first tank 2. This third tank 4 or intermediate tank is intended to contain a liquefied gas, for example nitrogen, to form a heat shield ensuring thermal insulation of the first 2 tank.

Par exemple, le troisième réservoir 4 peut comprendre ou être constitué de deux viroles cylindriques concentriques espacées (diamètres différents) et reliées et fermées à leurs extrémités par des cloisons. Ces deux parois cylindriques forment ainsi une capacité annulaire ayant la double fonction de stockage de l'azote liquide et d'écran thermique du premier réservoir 2.For example, the third tank 4 may comprise or be made up of two concentric cylindrical shells spaced apart (different diameters) and connected and closed at their ends by partitions. These two cylindrical walls thus form an annular capacity having the dual function of storing liquid nitrogen and providing a heat shield for the first tank 2.

Pour une faible hauteur annulaire, par exemple de 40mm, le volume ainsi créé peut être de 3100 litres pour un ISO conteur de 40 pieds (12 mètres environ).For a low annular height, for example 40mm, the volume thus created can be 3100 liters for an ISO counter of 40 feet (approximately 12 meters).

De préférence, le conteneur 1 comprend en outre une ou des parois 11, 12 écran reliées thermiquement au troisième 4 réservoir et disposés au niveau des extrémités du réservoir entre le premier 2 et le second 3 réservoir.Preferably, the container 1 further comprises one or more screen walls 11, 12 thermally connected to the third 4 tank and arranged at the ends of the tank between the first 2 and the second 3 tank.

Ces parois 11, 12 (plaques d'aluminium ou de cuivre par exemple) forment des couvercles au niveau des extrémités ou fonds du réservoir pour refermer l'écran autour du premier réservoir 2. Ces plaques sont « thermalisées » (c'est-à-dire mises en froid) par le troisième réservoir 4.These walls 11, 12 (aluminum or copper plates for example) form covers at the ends or bottoms of the tank to close the screen around the first tank 2. These plates are “thermalized” (i.e. i.e. cooled) by the third tank 4.

Le conteneur 1 comprend un dispositif de maintien des premier 2 et troisième 4 réservoir dans le second réservoir 3.The container 1 includes a device for holding the first 2 and third 4 tanks in the second tank 3.

Le système de maintien assure un support/une suspension des premier 2 et troisième 4 réservoir dans le second réservoir 3.The holding system provides support/suspension of the first 2 and third 4 tanks in the second tank 3.

Ce système de maintien est configuré pour permette un débattement limité des premier 2 et troisième 4 réservoirs dans le second réservoir 3 notamment selon la direction longitudinale A lors de leurs variations dimensionnelles (dilatations/rétractions selon les états chaud ou froid).This holding system is configured to allow limited movement of the first 2 and third 4 tanks in the second tank 3 in particular according to the direction longitudinal A during their dimensional variations (expansions/retractions depending on the hot or cold states).

Comme visibles aux figures, le système de maintien comprend un ensemble de tirants 5, 6 dont au moins une partie possèdent une première extrémité 7 reliée de façon articulée au second 3 réservoir et une seconde extrémité 8, 9 reliée de façon rigide au premier réservoir 2 ou au troisième réservoir 4 (ou à une pièce de structure rigidement liée à ces derniers) .As visible in the figures, the holding system comprises a set of tie rods 5, 6 of which at least part have a first end 7 articulatedly connected to the second 3 tank and a second end 8, 9 rigidly connected to the first tank 2 or to the third tank 4 (or to a structural part rigidly linked to the latter).

Comme schématisé à la figure 1, les tirants 5, 6 articulés sont mobiles entre deux positions angulaires déterminées définissants respectivement deux positions distinctes de la seconde extrémité 8, 9 des tirants. Ces deux positions correspondent respectivement aux extrêmes des variations dimensionnelles, notamment longitudinales, des premier 2 et troisième 4 réservoirs par rapport au second réservoir 3.As schematized in figure 1 , the articulated tie rods 5, 6 are movable between two determined angular positions respectively defining two distinct positions of the second end 8, 9 of the tie rods. These two positions correspond respectively to the extremes of the dimensional variations, in particular longitudinal, of the first 2 and third 4 tanks relative to the second tank 3.

Comme visible à la figure 1, le conteneur 1 peut comporter une liaison 15 fixe et rigide entre d'une part, une extrémité longitudinale du second réservoir 3 et, d'autre part, l'extrémité longitudinale adjacente du premier réservoir 2 et une extrémité du troisième réservoir 4 ou d'un élément de support solidaire de ce dernier. C'est-à-dire que la liaison 15 fixe et rigide bloque le déplacement longitudinal d'une extrémité longitudinale du premier 2 et du troisième 4 réservoir par rapport au second réservoir 3 tout en permettant un débattement longitudinal de l'extrémité opposée du premier 2 et troisième 4 réservoir par rapport au second réservoir 3.As visible at figure 1 , the container 1 may comprise a fixed and rigid connection 15 between, on the one hand, a longitudinal end of the second tank 3 and, on the other hand, the adjacent longitudinal end of the first tank 2 and one end of the third tank 4 or a support element integral with the latter. That is to say that the fixed and rigid connection 15 blocks the longitudinal movement of one longitudinal end of the first 2 and the third 4 tank relative to the second tank 3 while allowing longitudinal movement of the opposite end of the first 2 and third 4 tank relative to the second tank 3.

Ainsi, dans ce cas, les tirants 5, 6 articulés sont de préférence situés à l'autre extrémité (opposée à la liaison 15 fixe) qui possède un moins ce degré de liberté longitudinal.Thus, in this case, the articulated tie rods 5, 6 are preferably located at the other end (opposite the fixed connection 15) which has a minus this longitudinal degree of freedom.

Le système de maintien peut comporter un premier ensemble de tirants 5, ayant une première extrémité 7 reliée au second réservoir 3 et une seconde extrémité 8 reliée rigidement au premier réservoir 2. Ce premier ensemble de tirants 5 comprend une pluralité de tirants 5, notamment quatre tirants 5 dont la première extrémité 7 est située à une première extrémité longitudinale du second réservoir 3 (par exemple l'extrémité de gauche sur la figure 1), la seconde extrémité 8 des tirants 5 est raccordée à une première extrémité longitudinale du premier réservoir 2 (extrémité de gauche sur la figure 1).The holding system may comprise a first set of tie rods 5, having a first end 7 connected to the second tank 3 and a second end 8 rigidly connected to the first tank 2. This first set of tie rods 5 comprises a plurality of tie rods 5, in particular four tie rods 5 whose first end 7 is located at a first longitudinal end of the second tank 3 (for example the left end on the figure 1 ), the second end 8 of the tie rods 5 is connected to a first longitudinal end of the first tank 2 (left end on the figure 1 ).

Comme illustré à la figure 4, par exemple, le premier ensemble de tirants 5 peut comprendre deux tirants 5 supérieurs ayant leur première extrémité 7 raccordée en partie supérieure du second réservoir 3 et leur seconde extrémité 8 raccordée en partie inférieure du premier réservoir 2. De plus, les autres tirants 5 inférieurs peuvent avoir leur première extrémité 7 raccordée en partie inférieure du second réservoir 3 et leur seconde extrémité 8 raccordée en partie supérieure du premier réservoir 2.As illustrated in Figure 4 , for example, the first set of tie rods 5 may comprise two upper tie rods 5 having their first end 7 connected to the upper part of the second tank 3 and their second end 8 connected to the lower part of the first tank 2. In addition, the other tie rods 5 lower parts can have their first end 7 connected to the lower part of the second tank 3 and their second end 8 connected to the upper part of the first tank 2.

Les parties supérieures et inférieurs peuvent être définies selon qu'elles se trouvent au-dessus ou en dessous de l'axe longitudinal A central du réservoir 2 ou du conteneur 1.The upper and lower parts can be defined according to whether they are above or below the central longitudinal axis A of the tank 2 or the container 1.

Dans la variante de la figure 2 les tirants 5 inférieurs ont leur seconde extrémité 8 raccordée en partie inférieure ou centrale du premier réservoir 2 et les tirants 5 supérieurs ont leur seconde extrémité 8 raccordée en partie supérieure ou centrale du premier réservoir 2.In the variant of the figure 2 the lower tie rods 5 have their second end 8 connected to the lower or central part of the first tank 2 and the upper tie rods 5 have their second end 8 connected to the upper or central part of the first tank 2.

Le second réservoir 3 a de préférence une forme générale cylindrique s'étendant selon la direction longitudinale A avec un rayon déterminé compris par exemple entre 90 et 121,9 cm. Les tirants 5 du premier ensemble de tirants, respectivement du second ensemble de tirants, ont une longueur comprise de préférence entre 80 et 150% et de préférence entre 90 et 130% de la longueur dudit rayon.The second tank 3 preferably has a general cylindrical shape extending in the longitudinal direction A with a determined radius of, for example, between 90 and 121.9 cm. The tie rods 5 of the first set of tie rods, respectively of the second set of tie rods, have a length preferably between 80 and 150% and preferably between 90 and 130% of the length of said radius.

Comme visible à la figure 1, en vue de côté, de préférence les tirants 5 supérieurs se croisent avec les tirants 5 inférieurs (dans un plan parallèle à la direction longitudinale).As visible at figure 1 , in side view, preferably the upper tie rods 5 intersect with the tie rods 5 lower (in a plane parallel to the longitudinal direction).

Comme schématisé à la figure 1 ou 2, les secondes extrémités 8 des tirants 5 peuvent être logées dans des tube 18 ou gaines métalliques pour assurer la liaison au premier réservoir 2 en allongeant le chemin thermique. C'est-à-dire que chaque tube 18 est fixé (soudé par exemple) au premier réservoir 2 mais la fixation de la seconde extrémité 8 du tirant 5 à son tube 18 est déportée par rapport à la fixation entre le tube et le réservoir 2 pour allonger le chemin thermique.As schematized in figure 1 Or 2 , the second ends 8 of the tie rods 5 can be housed in tubes 18 or metal sheaths to ensure the connection to the first tank 2 by extending the thermal path. That is to say that each tube 18 is fixed (welded for example) to the first tank 2 but the fixing of the second end 8 of the tie rod 5 to its tube 18 is offset relative to the fixing between the tube and the tank 2 to lengthen the thermal path.

Par exemple, la seconde extrémité 8 de chaque tirant 5 est boulonnée (ou fixée de toute autre façon approprié) à une gaine ou toute qui est lui-même soudé (ou autre) au premier réservoir 2. De plus, comme visible à la figure 1, ces secondes extrémités 8 des tirants 5 peuvent être fixées à un anneau ou couronne solidaire de l'extrémité du premier réservoir 1.For example, the second end 8 of each tie rod 5 is bolted (or fixed in any other appropriate way) to a sheath or any which is itself welded (or other) to the first tank 2. In addition, as visible in the figure 1 , these second ends 8 of the tie rods 5 can be fixed to a ring or crown secured to the end of the first tank 1.

Comme illustré à la figure 2 (qui, par soucis de simplification, ne représente que le premier ensemble de tirants 5), selon un plan perpendiculaire à la direction longitudinale A les tirants 5 supérieurs peuvent se croiser selon un angle B compris entre 70 et 130 degrés et de préférence compris entre 90 et 120 degrés. De même, les tirants 5 inférieurs peuvent se croisent selon un angle compris entre 70 et 130 degrés et de préférence compris entre 90 et 120 degrés. Cf. également la figure 4.As illustrated in figure 2 (which, for the sake of simplification, only represents the first set of tie rods 5), according to a plane perpendicular to the longitudinal direction A the upper tie rods 5 can cross at an angle B between 70 and 130 degrees and preferably between 90 and 120 degrees. Likewise, the lower tie rods 5 can intersect at an angle between 70 and 130 degrees and preferably between 90 and 120 degrees. See also the Figure 4 .

De préférence, ce premier ensemble de tirants 5 n'est pas articulé ou faiblement articulé pour assurer un maintien fixe (ou une faible tolérance de déplacement) de la première extrémité du premier réservoir 2 par rapport au second réservoir 3 (notamment dans le cas de la liaison fixe 15).Preferably, this first set of tie rods 5 is not articulated or weakly articulated to ensure fixed maintenance (or a low tolerance of movement) of the first end of the first tank 2 relative to the second tank 3 (particularly in the case of the fixed connection 15).

Le conteneur 1 comprend second ensemble de tirants 5 de même nature que le premier ensemble au niveau de l'autre extrémité longitudinale du conteneur 1 (à droite sur la figure 1). Ces tirants 5 du second ensemble ont une première extrémité 7 reliée au second réservoir 3 et une seconde extrémité 8 reliée rigidement au premier réservoir 2. Ce second ensemble de tirants comprend une pluralité de tirants 5, notamment quatre tirants 5 dont la première extrémité 7 est située à la seconde extrémité longitudinale du second réservoir 3. La seconde extrémité 8 des tirants 5 est raccordée à la seconde extrémité longitudinale du premier réservoir 2 (comme précédemment de préférence via un anneau ou tube solidaire de l'extrémité du premier réservoir 2.The container 1 comprises a second set of tie rods 5 of the same nature as the first set at the level of the other longitudinal end of container 1 (on the right on the figure 1 ). These tie rods 5 of the second set have a first end 7 connected to the second tank 3 and a second end 8 rigidly connected to the first tank 2. This second set of tie rods comprises a plurality of tie rods 5, in particular four tie rods 5 whose first end 7 is located at the second longitudinal end of the second tank 3. The second end 8 of the tie rods 5 is connected to the second longitudinal end of the first tank 2 (as previously preferably via a ring or tube secured to the end of the first tank 2.

Les tirants du second ensemble de tirants 5 peuvent être agencés comme ceux du premier ensemble (cf. figure 2 ou 4 et description ci-dessus).The tie rods of the second set of tie rods 5 can be arranged like those of the first set (cf. figure 2 Or 4 and description above).

A chaque extrémité longitudinale du conteneur 1, les secondes extrémités 8 des tirants 5 peuvent être reliées au premier réservoir 2 ou à un col fixé à ce dernier.At each longitudinal end of the container 1, the second ends 8 of the tie rods 5 can be connected to the first tank 2 or to a neck fixed to the latter.

De plus, de préférence, les extrémités 7 des tirants 5 du second ensemble sont articulées pour permettre notamment un débattement de la seconde extrémité du premier réservoir 2 selon la direction longitudinale (cf. figure 1 la position rétractée en pointillés).Furthermore, preferably, the ends 7 of the tie rods 5 of the second assembly are articulated to allow in particular movement of the second end of the first tank 2 in the longitudinal direction (cf. figure 1 the retracted position in dotted lines).

Comme visible aux figures 1, 3 et 4, le conteneur 1 comprend un troisième ensemble de tirants 6, notamment quatre tirants 6 ayant une première extrémité 10 reliée au second réservoir 3 et une seconde extrémité 9 reliée au troisième réservoir 4 via un support 11, 12, 13 relié rigidement à ce dernier. Comme visible aux figures 3 et 4, la première extrémité 10 des tirants 6 du troisième ensemble est située au niveau la première extrémité longitudinale du second réservoir 3. La seconde extrémité 9 desdits tirants 6 étant située au niveau de la première extrémité longitudinale du conteneur 1.As visible to figures 1 , 3 And 4 , the container 1 comprises a third set of tie rods 6, in particular four tie rods 6 having a first end 10 connected to the second tank 3 and a second end 9 connected to the third tank 4 via a support 11, 12, 13 rigidly connected to the latter. As visible to figures 3 And 4 , the first end 10 of the tie rods 6 of the third set is located at the first longitudinal end of the second tank 3. The second end 9 of said tie rods 6 being located at the level of the first longitudinal end of the container 1.

Le troisième ensemble de tirants 6 comprend de préférence deux tirants 6 supérieurs dont la première extrémité 10 est situées en partie supérieure du second réservoir 3 et la seconde extrémité 9 est située en partie supérieure du premier réservoir 2 (cf. figures 3 et 4). Les deux tirants 6 inférieurs ont de préférence la première extrémité 10 raccordée en partie inférieure du second réservoir 3 et la seconde extrémité 9 située en partie inférieure du premier réservoir 2.The third set of tie rods 6 preferably comprises two upper tie rods 6 whose first end 10 is located in the upper part of the second tank 3 and the second end 9 is located in the upper part of the first tank 2 (cf. figures 3 And 4 ). The two lower tie rods 6 preferably have the first end 10 connected to the lower part of the second tank 3 and the second end 9 located in the lower part of the first tank 2.

De préférence, selon un plan perpendiculaire à la direction longitudinale A (cf. figure 3 ou 4), les deux tirants 6 supérieurs sont orientés relativement avec un angle compris entre 60 et 110 degrés et de préférence entre 70 et 90 degrés et les deux tirants 6 inférieurs sont orientés relativement avec un angle compris entre 60 et 110 degrés et de préférence entre 60 et 90 degrés.Preferably, along a plane perpendicular to the longitudinal direction A (cf. Figure 3 Or 4 ), the two upper tie rods 6 are oriented relatively with an angle of between 60 and 110 degrees and preferably between 70 and 90 degrees and the two lower tie rods 6 are oriented relatively with an angle of between 60 and 110 degrees and preferably between 60 and 90 degrees.

Le conteneur 1 comprend un quatrième ensemble de tirants 6 à l'autre extrémité du conteneur 1 qui peut être agencé selon la même configuration que le troisième ensemble (cf. ci-dessus et figures 3 et 4).Container 1 includes a fourth set of tie rods 6 at the other end of container 1 which can be arranged in the same configuration as the third set (see above and figures 3 And 4 ).

Les tirants 6 du troisième ensemble de tirants, respectivement du quatrième ensemble de tirants, ont une longueur comprise entre 30 et 80% et de préférence entre 40 et 60% de la longueur du rayon du de la section du second réservoir 2.The tie rods 6 of the third set of tie rods, respectively of the fourth set of tie rods, have a length of between 30 and 80% and preferably between 40 and 60% of the length of the radius of the section of the second tank 2.

Ainsi, les deux réservoirs 2, 4 internes sont portés et suspendus dans le premier réservoir externe 1 via des tirants 5, 6 situés aux deux extrémités du conteneur 1.Thus, the two internal tanks 2, 4 are carried and suspended in the first external tank 1 via tie rods 5, 6 located at the two ends of the container 1.

Comme illustré à la figure 1, les secondes extrémités des tirants 6 supportant le troisième réservoir 4 peuvent être reliés à des anneaux 13 ou plaques solidarisées au troisième réservoir 4 via les parois écran 11, 12.As illustrated in figure 1 , the second ends of the tie rods 6 supporting the third tank 4 can be connected to rings 13 or plates secured to the third tank 4 via the screen walls 11, 12.

C'est-à-dire que les secondes extrémités 9 des tirants 6 peuvent être reliées à des anneaux 13 respectif formant également le support des parois écran 11, 12.That is to say that the second ends 9 of the tie rods 6 can be connected to respective rings 13 also forming the support of the screen walls 11, 12.

De plus, comme visible à la figure 4, tout ou partie des tirants 5, 6 peuvent traverser ces parois écran 11, 12 via des orifices 17 respectifs.Furthermore, as visible in Figure 4 , all or part of the tie rods 5, 6 can pass through these screen walls 11, 12 via respective orifices 17.

D'autres tirants ou organes de maintien/support peuvent éventuellement facultativement être prévus entre ces deux extrémités du conteneur 1.Other tie rods or holding/support members may optionally be provided between these two ends of the container 1.

Les tirants 5, 6 articulés (à l'extrémité libre des premier et troisième réservoirs) sont configurés pour pivoter autour de leur extrémité 7, 10 reliée au second réservoir 3 selon un angle compris par exemple entre 10 et 20 degrés et correspondant à un débattement selon la direction longitudinale de leur seconde extrémité 8, 9 comprise par exemple entre 1 et 50mm et notamment entre 30 et 40mm (pour un conteneur ayant une longueur de l'ordre de 12 mètres).The articulated tie rods 5, 6 (at the free end of the first and third tanks) are configured to pivot around their end 7, 10 connected to the second tank 3 at an angle comprised for example between 10 and 20 degrees and corresponding to a clearance according to the longitudinal direction of their second end 8, 9, for example between 1 and 50mm and in particular between 30 and 40mm (for a container having a length of around 12 meters).

Dans le cas d'une la liaison 15 fixe et rigide à une extrémité longitudinale, cela bloque le déplacement longitudinal d'une extrémité longitudinale du premier 2 et du troisième 4 réservoir par rapport au second réservoir 3 tout en permettant un débattement longitudinal de l'extrémité longitudinale opposée du premier 2 et troisième 4 réservoir par rapport au second réservoir 3. Ce débattement est rendu possible via les tirants 5, 6 articulés.In the case of a fixed and rigid connection 15 at a longitudinal end, this blocks the longitudinal movement of a longitudinal end of the first 2 and the third 4 tank relative to the second tank 3 while allowing longitudinal movement of the opposite longitudinal end of the first 2 and third 4 tank relative to the second tank 3. This movement is made possible via the articulated tie rods 5, 6.

De plus, de préférence, moins une partie des extrémités 10 et 7 des tirants 5, 6 raccordés à la partie inférieure du second réservoir 3 sont montées sur des supports élastiques 14 respectifs permettant un amortissement un débattement vertical limité par rapport au second réservoir 3. Ces supports élastiques 14 peuvent comprendre par exemple un empilement de rondelles de Belleville, un amortisseur, un ressort ou tout autre organe approprié.Furthermore, preferably, less part of the ends 10 and 7 of the tie rods 5, 6 connected to the lower part of the second tank 3 are mounted on respective elastic supports 14 allowing damping and limited vertical movement relative to the second tank 3. These elastic supports 14 may include, for example, a stack of Belleville washers, a shock absorber, a spring or any other suitable member.

Classiquement, la liaison 15 fixe et rigide peut comprendre des parois tubulaires formant les aller-retours selon la direction longitudinale A pour constituer un chemin thermique d'isolation entre d'une part, le second réservoir 3 et, d'autre part, les premier 2 et troisième 4 réservoirs (cf. par exemple DE102014206370A1 ). Ce chemin thermique peut comprendre un tube en composite époxy/verre ou autre sur le chemin thermique.Conventionally, the fixed and rigid connection 15 can comprise tubular walls forming the back and forth in the longitudinal direction A to constitute a thermal insulation path between, on the one hand, the second tank 3 and, on the other hand, the first 2 and third 4 tanks (see for example DE102014206370A1 ). This thermal path may include an epoxy/glass composite tube or other on the thermal path.

Comme schématisé à la figure 6, la liaison fixe 15 axiale (selon la direction longitudinale A) entre le second réservoir 3 et le premier réservoir 2 peut comprendre une paroi 25 (composite époxy/verre ou métallique tel que du titane par exemple) dont une extrémité 125 est bloqué longitudinalement par une butée 225 longitudinale solidaire du premier réservoir 2. La butée longitudinale 225 est par exemple bride de fixation empêchant la rotation relative des deux pièces).As schematized in Figure 6 , the fixed axial connection 15 (in the longitudinal direction A) between the second tank 3 and the first tank 2 can comprise a wall 25 (epoxy/glass or metallic composite such as titanium for example) of which one end 125 is blocked longitudinally by a longitudinal stop 225 secured to the first tank 2. The longitudinal stop 225 is for example a fixing flange preventing the relative rotation of the two parts).

Comme illustré aux figures 7 et 8, les deux parois cylindriques délimitant le troisième réservoir 4 peuvent comprendre des entretoises ou raidisseurs les séparant. Ceci permet de minimiser l'épaisseur des parois ou viroles en équilibrant l'effet de la pression et en renforçant l'ensemble notamment axialement (selon la direction longitudinale A). La flèche de la partie cylindrique est de quelques millimètres en pleine charge d'azote liquide et sous 4g d'accélération lors de la manutention. L'azote évaporé peut être évacué à l'atmosphère par une tuyauterie non représentée par soucis de simplification. La pression y peut être maintenue à typiquement 0.5 bar par un déverseur. Ce troisième réservoir 4 annulaire peut également être équipé de tuyauterie de remplissage et d'une ligne de sécurité connectée à une soupape.As illustrated in figures 7 and 8 , the two cylindrical walls delimiting the third tank 4 may include spacers or stiffeners separating them. This makes it possible to minimize the thickness of the walls or shells by balancing the effect of the pressure and by reinforcing the whole, particularly axially (in the longitudinal direction A). The deflection of the cylindrical part is a few millimeters when fully charged with liquid nitrogen and under 4g of acceleration during handling. The evaporated nitrogen can be evacuated to the atmosphere via piping not shown for the sake of simplification. The pressure there can be maintained at typically 0.5 bar by a pressure relief valve. This third annular tank 4 can also be equipped with filling piping and a safety line connected to a valve.

Comme visible aux figures 7 et 8 et sans que ceci soit limitatif, les entretoises 16 ou raidisseurs peuvent s'étendre selon la direction longitudinale A. cette configuration permet notamment une fabrication des deux parois et de leur(s) entretoises par extrusion.As visible to figures 7 and 8 and without this being limiting, the spacers 16 or stiffeners can extend in the longitudinal direction A. this configuration allows in particular a manufacture of the two walls and their spacer(s) by extrusion.

Ainsi, tout en étant de structure simple et peu coûteuse, le conteneur 1 permet d'augmenter la capacité d'azote, par exemple de 1200 litres à 3000 litres avec une hauteur annulaire de 40mm (distance séparant les deux parois concentriques du troisième réservoir 4). Cette configuration minimise la réduction de la capacité du premier réservoir 2.Thus, while being simple and inexpensive in structure, the container 1 makes it possible to increase the nitrogen capacity, for example from 1200 liters to 3000 liters with an annular height of 40mm (distance separating the two concentric walls of the third tank 4 ). This configuration minimizes the reduction in the capacity of the first tank 2.

La structure hyperstatique de support permet une répartition homogène de la masse du troisième réservoir 4 pour éviter une surcharge sur les essieux arrière en cas de transport routier ou un déséquilibre lors de la manutentionThe hyperstatic support structure allows a homogeneous distribution of the mass of the third tank 4 to avoid overloading on the rear axles in the event of road transport or an imbalance during handling

Cette architecture permet de garantir une très bonne thermalisation (pas besoin de circuit de refroidissement). Ce concept fonctionne même avec une très faible quantité d'azote à la fin du voyage. Les entrées de chaleur sont transmises par conduction par les viroles 4 vers l'azote liquide. Il n'y a pas de risque de disfonctionnement du circuit de refroidissement à faible débit d'évaporation et d'élévation de la température dans la partie supérieure du troisième réservoir 4.This architecture guarantees very good thermalization (no need for a cooling circuit). This concept works even with a very small amount of nitrogen at the end of the journey. The heat inputs are transmitted by conduction through the ferrules 4 to the liquid nitrogen. There is no risk of malfunction of the cooling circuit at low evaporation flow and of temperature rise in the upper part of the third tank 4.

Les deux parois cylindriques du troisième réservoir 4 (viroles) agissent comme deux écrans thermiques en série. La paroi extérieure reçoit le flux de chaleur provenant du second réservoir 3. La paroi intérieure reçoit le flux de chaleur de la paroi externe qui a une température proche par exemple de 90K. Ceci réduit le flux de chaleur vers le premier réservoir 2 (par exemple à 4K).The two cylindrical walls of the third tank 4 (shells) act as two heat shields in series. The outer wall receives the heat flow coming from the second tank 3. The inner wall receives the heat flow from the outer wall which has a temperature close to, for example, 90K. This reduces the heat flow to the first tank 2 (for example to 4K).

La structure hyperstatique de support et de maintien permet une bonne répartition des masses, un maintien autorisant les dilatations et rétractations et une tenue lors des transports.The hyperstatic support and retention structure allows good distribution of masses, support allowing expansion and retraction and stability during transport.

Le troisième réservoir 4 (et les parois écran 11, 12) est un ensemble rigide pouvant être autoporté par les tirants 6 depuis la paroi du second réservoir 3. Ceci permet d'éviter la compression de l'isolation inter-parois. Ceci évite donc des défauts thermiques et améliore le dégazage de l'isolation en évitant le tassement local de la matière isolante.The third tank 4 (and the screen walls 11, 12) is a rigid assembly which can be self-supported by the tie rods 6 from the wall of the second tank 3. This makes it possible to avoid compression of the inter-wall insulation. This therefore avoids thermal defects and improves the degassing of the insulation by avoiding local settling of the insulating material.

Le troisième réservoir 4 formant écran peut être en appui direct sur l'isolation disposée autour du premier réservoir 2. Cette isolation non représentée peut comprendre des couches de matériaux isolants utilisés classiquement.The third tank 4 forming a screen can rest directly on the insulation placed around the first tank 2. This insulation, not shown, can include layers of insulating materials used conventionally.

Le conteneur peut être logé (fixé) à un cadre parallélépipédique permettant sont transport.The container can be housed (fixed) to a parallelepiped frame allowing transport.
