Problems solved by technology

[0004] A disadvantage of this tank wall is that its installation
The fact that the elements of the stiffener frame, namely the corrugated stiffener and the connecting members, are free or weakly fixed relative to each other complicates the transfer of the stiffener frame to the insulator

Embodiment Construction

[0051] The features, alternatives and various embodiments of the invention may be associated with each other in various combinations as long as they are not incompatible or mutually exclusive. In particular, alternative forms of the invention are conceivable which comprise only a selection of the features described below, and no other features described, if said selection of features is sufficient to confer a technical advantage on the invention or to distinguish the invention from the prior art .

[0052] figure 1 Shown is a ship 1 , such as a methane carrier, comprising four tanks 2 for storing liquid gas, in particular liquid natural gas. The tanks 2 are separated from each other by a transverse double partition 4 (also called "cofferdam"). Each tank 2 is formed by a wall 6 comprising, inter alia, thermal insulation ( image 3 Visible in ) and a corrugated membrane, which partially forms the thermal insulation of the wall 6, comprising a plurality of corrugated plates, w...

Abstract

The present invention relates to a method for mounting a wall (6) of a tank (2) for a liquid cargo transport vessel (1) comprising, inter alia, an insulating foundation (8), at least one corrugated plate (100) comprising series of corrugations (110, 120), the wall (6) comprising at least one corrugation reinforcement (21, 22) configured to be housed in at least one corrugation (110, 120) of the corrugated plate (100), method in which at least one maintaining device (50) is inserted into a corrugation reinforcement (20), making it possible to arrange the corrugation reinforcement (20) on the insulating foundation (8).

Description

technical field [0001] The field of the invention is transport tanks with insulating membranes for storing and / or transporting fluids, in particular sealed and insulated tanks for liquefied natural gas. Background technique [0002] The present invention relates to the field of sealed and insulated tanks for storing and / or transporting liquids at low temperatures, such as tanks for transporting liquefied petroleum gas (LPG), having a temperature of, for example, 50°C to 0°C, or with Tanks for transporting liquefied natural gas (LNG) at about -162°C and atmospheric pressure. These tanks can be installed on shore or on floating structures. In the case of floating structures, tanks may be used to transport liquid gas or receive liquid gas for use as fuel to propel the floating structure. [0003] Sealed and insulated tanks for storage of these liquids at cryogenic temperatures typically consist of thermal insulation and a corrugated membrane comprising a plurality of corrugat...
