Problems solved by technology

However, such a design is not satisfactory
This is because this fixation of the secondary sealing membrane to the coupling piece only achieves a point-like connection of the secondary sealing membrane, so it is not stressed in a uniform manner

Embodiment Construction

[0063] Traditionally, the terms "outer" and "inner" are used to define the relative position of elements relative to each other in terms of the inside and outside of the tank.

[0064] figure 1 with 2 The multilayer structure of a sealed and insulated tank for storing fluid is shown.

[0065] From the outside of the tank to the inside, each wall of the tank includes a secondary heat insulation barrier 1, a secondary sealing film 4, a primary heat insulation barrier 5, and a primary sealing film 7. The secondary heat insulation barrier includes passing through a secondary constraining member 8 Anchored to the juxtaposed insulation panel 2 of the supporting structure 3, the secondary sealing film is carried by the insulation panel 2 of the secondary insulation barrier 1, and the primary insulation barrier includes anchoring by the primary restraint member 19 On the juxtaposed insulation panel 6 of the insulation panel 2 of the secondary insulation barrier 1, the primary sealing film ...

Abstract

The present invention relates to a sealed thermally insulated tank for storing fluids, comprising a secondary thermally insulating barrier (1) and a secondary sealing membrane (4); the secondary sealing membrane (4) comprising a plurality of corrugated metal sheets ( 24), said corrugated metal sheets are hermetically welded to each other and each comprise at least two vertical corrugations (25, 26); the secondary thermal insulation barrier (1) comprises a plurality of juxtaposed insulating panels (2), each Each insulating panel (2) has an inner face (10) opposite the supporting wall, said inner face (10) being provided with metal sheets (17, 18) onto which corrugated metal sheets (24) are welded; each The insulating panels (2) are each associated with an adjacent insulating panel (2) by a plurality of bridging elements (22).

Description

Technical field [0001] The present invention relates to the field of film-sealed thermal insulation tanks for storing and / or transporting fluids such as cryogenic fluids. [0002] The membrane sealed and insulated tank is particularly used for storing liquefied natural gas (GNL), which is stored at approximately -162°C under atmospheric pressure. These tanks can be installed on the ground or on floating structures. In the case of a floating structure, the tank can be used for the transportation of liquefied natural gas or for receiving liquefied natural gas as a propellant fuel of the floating structure. Background technique [0003] In the prior art, sealed and insulated tanks for storing liquefied natural gas are known, and the tanks are integrated into a supporting structure, such as a double hull of a ship for transporting liquefied natural gas. Generally, such a tank includes a multi-layer structure that is sequentially arranged from the outside to the inside of the tank in ...
