Abstract: A sealed and thermally insulating tank has a bottom wall and a ceiling wall where at least a first pipe and a second pipe pass through the ceiling wall. The tank is equipped with a support foot that passes through the bottom wall that is fastened to the load-bearing structure with a guide device that is fastened to the support foot. The guide device is configured to guide the first pipe and second pipe in translation in the vertical direction where the guide device has a first collar disposed around the entirety of the first pipe and a second collar is disposed around the entirety of the second pipe. A support plate is fastened to the support foot. A first linking arm links the first collar to the support plate. A second linking arm links the second collar to the support plate.

Abstract: 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.

Abstract: A tank for transporting and/or storing a liquefied gas includes: a load-bearing structure, a plurality of walls each including, in a thickness direction of the wall, a thermally insulating layer resting against the load-bearing structure and a sealing membrane resting against the thermally insulating layer. The plurality of walls includes a bottom wall, and a guiding structure configured to receive a tower for loading and/or unloading the liquefied gas contained in the tank. The guiding structure includes a base bearing against the load-bearing structure. The thermally insulating layer includes one self-supporting heatproof panel, and a clearance delimited by a portion of the self-supporting heatproof panel and by the load-bearing structure, the clearance being configured to accommodate part of the base of the guiding structure.

Abstract: A sealed and thermally insulating tank for transporting and/or storing liquefied natural gas includes a load-bearing structure and a storage structure surrounded by the load-bearing structure. The storage structure includes a first portion and a second portion that are sealed with respect to one another, the first portion and the second portion extending in one and the same plane which is parallel to the load-bearing structure. The tank includes a closure device arranged in the thickness of the storage structure. The closure device includes a first closure member and a second closure member that cooperate with one another to separate the first portion from second portion. One of the closure members includes a first part and a second part that extend in intersecting planes. One of the parts is connected to one of the portions by a fastening device that is arranged in the thickness of the storage structure.

Abstract: A securing device for securing a pipe in a housing, which has a cylindrical collar, at least three securing arms, each securing arm containing a proximal arm portion mounted on the cylindrical collar, a distal arm portion bearing a bearing pad, the bearing pad containing a bearing surface facing away from the collar and intended to collaborate with a wall of the housing in which at least one of the securing arms contains a guideway capable of translationally guiding the distal arm portion with respect to the proximal arm portion, an elastic member being coupled to the guideway so as to be able to apply a return force that pushes the distal arm portion away from the proximal arm portion.
