The invention relates to a method of testing a metallic cryogenic storage vessel before said vessel is put into operation, in which the vessel (1) is filled with water and, if necessary, appropriate measurements are taken. The invention is characterised in that it comprises the following steps consisting in: filling the metallic cryogenic storage vessel (1) with seawater; and providing the metallic base (2) and lateral walls (3) of the vessel (1), which are essentially made from plain steel, with temporary cathodic protection, by injecting an electric current into the anodes which are disposed inside the vessel (1) when said anodes are submerged. It is preferable to arrange a network of first anode(s) (51) immediately next to the base of the vessel using a support means (5 2), preferably with the option of removing said support means (5 2) and first anode(s) (51). In addition, it is advantageous if the first anodes (51) are disposed along a circle (C1) which is concentric to the centre of the surface of the vessel base and if the diameter of said circle (C1) is between 40 and 75 % of that of the surface of the base (2) of the vessel.
