Abstract
A method for checking the sealing of a sealed tank for storing a liquefied gas at low temperature, the tank having an inner hull and a secondary sealing membrane, a secondary space that is arranged between the inner hull and the secondary sealing membrane, a primary sealing membrane and a primary space that is arranged between the primary sealing membrane and the secondary sealing membrane is disclosed. The method has the following main steps: generating a pressure lower than the pressure of the primary space in the secondary space using a suction device, measuring the temperature of an outer surface of the inner hull, and detecting the location of a sealing defect of the secondary sealing membrane in the form of a cold spot on the outer surface of the inner hull.
