Description
L’invention se rapporte au domaine des installations de stockage pour gaz liquéfié comprenant une cuve étanche et thermiquement isolante, à membrane étanche. En particulier, l’invention se rapporte au domaine des cuves étanches et thermiquement isolantes pour le stockage et/ou le transport de gaz liquéfié à basse température, telles que des cuves pour le transport de Gaz de Pétrole Liquéfié (aussi appelé GPL) présentant par exemple une température comprise entre -50°C et 0°C, ou pour le transport de Gaz Naturel Liquéfié (GNL) à environ -162°C à pression atmosphérique. Ces cuves peuvent être installées à terre ou sur un ouvrage flottant. Dans le cas d’un ouvrage flottant, la cuve peut être destinée au transport de gaz liquéfié ou à recevoir du gaz liquéfié servant de carburant pour la propulsion de l’ouvrage flottant.The invention relates to the field of storage facilities for liquefied gas comprising a sealed and thermally insulating tank, with a sealed membrane. In particular, the invention relates to the field of sealed and thermally insulating tanks for the storage and/or transport of liquefied gas at low temperature, such as tanks for the transport of Liquefied Petroleum Gas (also called LPG) having for example a temperature between -50°C and 0°C, or for the transport of Liquefied Natural Gas (LNG) at around -162°C at atmospheric pressure. These tanks can be installed on land or on a floating structure. In the case of a floating structure, the tank may be intended for the transport of liquefied gas or to receive liquefied gas used as fuel for the propulsion of the floating structure.
Dans un mode de réalisation, le gaz liquéfié est du GNL, à savoir un mélange à forte teneur en méthane stocké à une température d’environ -162°C à la pression atmosphérique. D’autres gaz liquéfiés peuvent aussi être envisagés, notamment l’éthane le propane, le butane ou l’éthylène mais aussi l’hydrogène ou l’ammoniac.In one embodiment, the liquefied gas is LNG, namely a mixture with a high methane content stored at a temperature of approximately -162°C at atmospheric pressure. Other liquefied gases can also be considered, in particular ethane, propane, butane or ethylene, but also hydrogen or ammonia.
Arrière-plan technologiqueTechnology background
Une cuve étanche et thermiquement isolante de stockage de gaz naturel liquéfié agencée dans une structure porteuse présente une structure multicouche, à savoir de l’extérieur vers l’intérieur, selon la direction d’épaisseur de la paroi de cuve, une barrière thermiquement isolante secondaire ancrée sur la structure porteuse, une membrane étanche secondaire reposant sur la barrière thermiquement isolante secondaire, une barrière thermiquement isolante primaire reposant contre la membrane étanche secondaire et une membrane étanche primaire reposant contre la barrière thermiquement isolante primaire et destinée à être en contact avec le gaz naturel liquéfié stocké dans la cuve.A sealed and thermally insulating liquefied natural gas storage tank arranged in a support structure has a multilayer structure, namely from the outside inwards, in the thickness direction of the tank wall, a secondary thermally insulating barrier anchored on the load-bearing structure, a secondary waterproof membrane resting on the secondary thermally insulating barrier, a primary thermally insulating barrier resting against the secondary waterproof membrane and a primary waterproof membrane resting against the primary thermally insulating barrier and intended to be in contact with the gas liquefied natural stored in the tank.
Selon un exemple de réalisation d’une telle cuve, chaque barrière thermiquement isolante, respectivement primaire et secondaire, comporte un ensemble de panneaux isolants, de forme générale parallélépipédique qui sont juxtaposés et forment ainsi une surface de support pour la membrane étanche, respectivement primaire et secondaire, supportée par chacune de ces barrières. Cette surface de support doit présenter une bonne planéité afin de fournir un appui continu et plat pour les membranes étanches. En effet, les parois de cuves sont sujettes à de nombreuses contraintes thermiques, hydrostatiques et hydrodynamiques lorsque la cuve contient du GNL. Une surface d’appui plane et continue permet d’éviter la génération de zones de concentration des contraintes dans la membrane étanche, ces zones de concentration des contraintes pouvant entraîner la dégradation de la membrane étanche.According to an embodiment of such a tank, each thermally insulating barrier, respectively primary and secondary, comprises a set of insulating panels, of generally parallelepiped shape which are juxtaposed and thus form a support surface for the sealed membrane, respectively primary and secondary, supported by each of these barriers. This support surface must have good flatness in order to provide a continuous and flat support for the waterproof membranes. Indeed, the vessel walls are subject to numerous thermal, hydrostatic and hydrodynamic stresses when the vessel contains LNG. A flat and continuous support surface avoids the generation of stress concentration zones in the waterproof membrane, these stress concentration zones being able to lead to the degradation of the waterproof membrane.
Bien que les panneaux isolants présentent une surface interne plane pour former la surface de support de la membrane étanche, la structure porteuse sur laquelle sont ancrés lesdits panneaux ne présente, elle, pas toujours une planéité suffisante pour que les panneaux ancrés sur ladite structure porteuse forment une surface de support continue et plane. Par exemple, lorsque la structure porteuse est formée par la double coque d’un navire, les zones de jonction entre les différentes portions de la double coque forment des irrégularités par rapport au plan général d’une paroi porteuse, ces irrégularités peuvent par, exemple, être liées à la soudure entre lesdites portions de la double coque.Although the insulating panels have a flat internal surface to form the support surface of the waterproof membrane, the supporting structure on which the said panels are anchored does not always have sufficient flatness for the panels anchored to the said supporting structure to form a continuous, level support surface. For example, when the load-bearing structure is formed by the double hull of a ship, the junction zones between the different portions of the double hull form irregularities with respect to the general plane of a load-bearing wall, these irregularities can for example , be linked to the weld between said portions of the double hull.
Afin de rattraper ces défauts de planéité, des cordons de mastic sont habituellement intercalés entre les panneaux isolants et la structure porteuse. En particulier, les cordons de mastic peuvent être déposés entre la surface externe des panneaux isolants de la barrière thermiquement isolante secondaire dans un état plastique, puis appuyés contre la paroi porteuse pour fluer jusqu’à remplir exactement l’écart entre la paroi porteuse et les panneaux isolants lorsque ceux-ci sont dans leur position finale.In order to compensate for these flatness defects, mastic beads are usually inserted between the insulating panels and the load-bearing structure. In particular, the beads of mastic can be deposited between the external surface of the insulating panels of the secondary thermally insulating barrier in a plastic state, then pressed against the load-bearing wall to creep until exactly filling the gap between the load-bearing wall and the insulation panels when they are in their final position.
Les mastics utilisés aujourd’hui sont classiquement des résines époxyde. Elles sont souvent utilisées sous forme de deux composants principaux : une résine époxyde et un durcisseur. C’est la réaction de polymérisation (ou réticulation) entre les deux composants une fois mélangés qui confère aux résines époxyde leur résistance et adhérence. Ce sont des résines aux propriétés structurales très efficaces.The sealants used today are conventionally epoxy resins. They are often used in the form of two main components: an epoxy resin and a hardener. It is the polymerization reaction (or crosslinking) between the two components once mixed that gives epoxy resins their resistance and adhesion. These are resins with very effective structural properties.
Toutefois, de telles résines présentent l’inconvénient d’être particulièrement rigides et fragiles à basses températures. Elles ne présentent pas des caractéristiques de résistance mécanique suffisantes, notamment du type résistance à la traction et au cisaillement lorsque la température extérieure est très basse, typiquement dans un environnement particulièrement froid, tel que l’océan arctique, de manière à résister à la pression du gaz liquéfié en mouvement dans la cuve.However, such resins have the disadvantage of being particularly rigid and brittle at low temperatures. They do not have sufficient mechanical strength characteristics, in particular of the tensile and shear strength type when the outside temperature is very low, typically in a particularly cold environment, such as the Arctic Ocean, so as to withstand the pressure liquefied gas moving in the tank.
RésuméSummary
La présente invention a pour but de proposer une solution permettant de résoudre les inconvénients précités et vise à protéger une cuve installée dans une structure porteuse dont le mastic présente des caractéristiques mécaniques du type résistance à la traction (décollement) et au cisaillement, à chaud (d’environ 20°C à environ 40°C) et à froid (par exemple d’environ -25°C à -60°C) améliorées, ces caractéristiques lui permettant notamment d'être utilisé comme mastic pour la reprise de planéité et l’adhésion des éléments d’isolation thermique sur les cuves de méthaniers ou de navires utilisant le GNL (Gaz Naturel Liquéfié) comme carburant, ou pour toutes autres applications à basse température.The aim of the present invention is to propose a solution making it possible to solve the aforementioned drawbacks and aims to protect a tank installed in a load-bearing structure whose mastic has mechanical characteristics of the tensile (detachment) and shear resistance type, when hot ( from about 20°C to about 40°C) and cold (for example from about -25°C to -60°C) improved, these characteristics allowing it in particular to be used as putty for restoring flatness and the adhesion of thermal insulation elements on the tanks of LNG carriers or ships using LNG (Liquefied Natural Gas) as fuel, or for any other low temperature applications.
