Abstract
A method is described for checking the sealing of a sealed and thermally insulating tank for storing a liquefied gas at low temperature. The tank has a primary space and a secondary space where, in order to perform the check, a difference in pressure is created between the two spaces at least some of the inert gas injected into the primary space is recovered via at least one secondary outlet of the secondary space so as to be reinjected into the primary space.
