FIELD: testing engineering.
SUBSTANCE: method comprises filling the metallic cryogenic tank with sea water, temporally protecting of sides and bottom of the tank by means of passing current through anodes mounted inside the tank just after submerging the tank into the water, and setting the first anode system in the vicinity of the bottom of the tank. The number of anodes and their capability to withstand the current are sufficient to produce a current density that provides the amount of the electrochemical potential required for protecting steel. A cryogenic vessel is proposed for realization of the method described.
EFFECT: enhanced efficiency and reduced cost.
