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.

A device for monitoring the tightness of a sealing component wherein the monitoring device has a box with a peripheral partition and a cover made of a transparent material is disclosed. The cover is connected to the peripheral partition such that the cover and the peripheral partition are able to define, with a sealing component, an inner chamber, the peripheral partition with an inner peripheral wall having a lower end equipped with an inner peripheral seal intended to be positioned against the sealing component all around the inner chamber, and an outer peripheral wall arranged outside the inner peripheral wall so as to define, between the outer peripheral wall and the inner peripheral wall, an intermediate chamber extending exclusively in the peripheral partition all around the inner chamber.
