Abstract
The present invention relates to a method of building a reservoir for storing liquefied natural gas at low temperature. This method consists in fixing on the internal wall 22 of the concrete vessel 3 a first thin lining 21 forming a first fluid-tight barrier, then in completely filling the space between the tank 2 and the concrete vessel 3 by means of a heat-insulating structure comprising an assembly of stacked blocks 25 of insulating material, associated with a second thin lining 24 forming a second fluid-tight barrier, said structure being supported by the concrete vessel and simply arranged round the inner tank. The building method according to the invention applies in particular to liquefied natural gas storage reservoirs installed on solid ground.
