The invention relates to a tank () for storing a liquefied gas, wherein the tank () includes peripheral walls (), the peripheral walls () including a sealing membrane and at least one thermal insulation barrier,

Sealed and thermally insulating tank comprising anti-convective filling elements

A sealed and thermally insulating tank including a thermally insulating barrier suitable for being anchored to a load-bearing structure is disclosed. The thermally insulating barrier including a plurality of insulating panels juxtaposed in a regular pattern, two adjacent insulating panels defining an inter-panel space, the inter-panel space including an outer portion and an inner portion superposed in the direction of the thickness of the thermally insulating barrier, the outer portion being suitable for being situated close to the load-bearing structure and the inner portion being close to the inside of the tank, the tank further including insulating seals, the insulating seals including two outer insulating seals, the said outer insulating seals being arranged juxtaposed in the outer portion of the inter-panel space so that they have two adjacent edges, and an inner insulating seal, the inner insulating seal being arranged in the inner portion of the inter-panel space.

Sealed and thermally insulating tank having anti-convection insulating seals

A sealed and thermally insulating tank incorporated in a supporting structure (), the tank including at least one inclined tank wall () forming an angle with a horizontal direction and fixed to a supporting wall of the supporting structure () is disclosed. The tank wall () has a multilayer structure including successively, in the direction of thickness from the outside to the inside of the tank, a thermally insulating barrier () held against the corresponding supporting wall and a sealed membrane () carried by the thermally insulating barrier (). The tank includes sealed strips () in the space formed between the thermally insulating barrier () and the supporting wall.

Thermally insulating sealed tank

A tank includes a secondary insulation barrier, a secondary sealing membrane resting on the secondary insulation barrier, a primary insulation barrier resting on the secondary sealing membrane, a primary sealing membrane resting on the primary insulation barrier, and a primary reinforcing member. The primary sealing membrane includes primary corrugations and the secondary sealing membrane includes secondary corrugations projecting toward the interior of the tank. The primary and secondary corrugations are superimposed along a thickness direction. The primary insulation barrier has passages, and the secondary corrugations are accommodated in the passages. A dimension of the primary insulation barrier is less than a dimension of the secondary corrugations along the thickness direction, so the secondary corrugations extend through the passages and are partially accommodated in the primary corrugations. The primary reinforcing member is interposed along the thickness direction between superimposed primary and secondary corrugations so as to reinforce the primary corrugation.

The invention relates to a tank wall () fixed onto a supporting wall () wherein the secondary insulating barrier comprises a plurality of secondary rows (A, B, C) parallel to a first direction and juxtaposed in a second direction at right angles to the first direction according to a repeated pattern. The secondary sealed membrane comprises a plurality of strakes () parallel to the first direction, the size of the repeated pattern of the secondary rows (A, B, C) being an integer multiple of the size of a strake () in the second direction. The primary insulating barrier () comprises a plurality of primary rows parallel to the first direction, and the primary sealed membrane has first corrugations () parallel to the first direction and spaced apart by a first regular spacing (), wherein the size of the repeated pattern of the primary rows is an integer multiple of said first regular spacing ().

A sealed and insulating reservoir contains a pressurized cold fluid in a rigid, sealed enclosure. A fluidtight membrane is positioned to contact the cold fluid contained in the reservoir. An insulating barrier is placed between the fluidtight membrane and the internal surface of the rigid enclosure, with the insulating barrier forming a support surface to support the fluidtight membrane. A pressure balancing device is able to limit the pressure difference between a first sealed volume located inside the fluidtight membrane, and a second sealed volume located outside the fluidtight membrane. The pressure balancing device typically includes a fluid circuit having two chambers sealingly separated by a movable separator. The first chamber is linked to the first sealed volume, and the second chamber is linked to the second sealed volume. The movable separator exerts a loading force in the direction of the second chamber.
