example 2

[0093] The pitch 40 of the corrugations is PO.

[0094] The pitch 41 of the corrugations is GO.

[0095] The width of the primary insulation panel 15 and the width of the secondary insulation panel 7 is 3GO.

[0096] The length of the primary insulation panel 15 and the length of the secondary insulation panel 7 is 4PO (rectangular shape).

[0097] The width of the slats 13 is 2PO.

[0098] The corrugated metal plate 21 has a length of 12PO.

[0099] The corrugated metal plate 21 has a width of 3GO.

[0100] PO=300mm.

[0101] GO=340mm.

example 3

[0103] The corrugations are not equidistant, but are arranged in a repeating pattern of four corrugations with successive spacings of:

[0104] 340mm; 340mm; 340mm; 180mm

[0105] Preferably, the 180mm gap is divided into two 90mm sections on two opposite edges of the corrugated metal sheet 21 .

[0106] Therefore, the size of the repeating pattern is 1,200 mm. For the rest, keep the dimensions of the first example.

example 4

[0108] The corrugations are not equidistant, but are arranged in a repeating pattern of four corrugations with successive spacings of:

[0109] 300mm; 400mm; 300mm; 200mm

[0110] Preferably, the 200mm gap is divided into two 100mm sections on two opposite edges of the corrugated metal sheet.

[0111] Therefore, the size of the repeating pattern is 1,200mm. For the rest, keep the dimensions of the first example.

[0112] figure 2 A detailed view of the attachment of the metal plate 21 of the primary sealing membrane 6 to the primary thermal insulation barrier using welding supports 26 is shown.

[0113] Each primary insulation panel 15 comprises a groove 27 in the cover plate 20 . like figure 1 and figure 2 As shown in , the grooves 27 can be produced continuously by creating intersections between the grooves 27 . At an intersection between two grooves 27, the groove may contain one anchor support 26 running continuously across the intersection, while the other groove...

Abstract

The invention relates to a thermally insulating and leaktight tank wall, the wall comprising: a sealing membrane (6) comprising a corrugated metal plate, a thermally insulating barrier (5) comprising a groove (27) extending in a longitudinal direction, at least one welding support (26) borne by the thermally insulating barrier, the welding support (26) comprising a lower part (28) held in the groove (27), an upper part (30) located on the thermally insulating barrier, an intermediate part (29) of the welding support (26) connecting the lower part (28) to the upper part (30), in which the at least one welding support (26) is mounted so as to be able to slide in said groove (27) in the longitudinal direction, and the corrugated metal plate is welded to the upper part (30) of the welding support (26), and in which the upper part (30) of the welding support (26) is accommodated in a counterbore (32) adjacent to the groove (27), the counterbore (32) being formed in the thermally insulating barrier such that the upper part (30) of the welding support (26) is located between the sealing membrane and the thermally insulating barrier and in the continuation of the support surface (31).

Description

technical field [0001] The invention relates to the field of sealed and thermally insulated containers with membranes. In particular, the invention relates to the field of sealed and insulated containers for storing and / or transporting cryogenic liquefied gases, such as liquefied petroleum gas (also called A container for LPG), or a container for the transport of liquefied natural gas (LNG) at approximately -162°C at atmospheric pressure. These vessels can be installed onshore or on floating structures. In the case of floating structures, the container may be used to transport liquefied gas or to receive liquefied gas used as fuel to propel the floating structure. Background technique [0002] Document WO2014 / 167227 discloses a sealed and thermally insulated container for storing liquefied gas in a structure comprising supporting walls. The vessel comprises a vessel wall attached to a support wall and comprising an insulating barrier of juxtaposed insulating blocks and a ...
