FIELD: rust and fouling protection of wide-purpose marine objects. SUBSTANCE: the method includes application of antirust coating and antifoulding coating in the form of solid current-conducting layer, combination of simultaneous and separate cathode polarization of structure and anode polarization of current-conducting layer, depending on the sea water flow speed and specific contact resistance of antirust coating. EFFECT: enhanced efficiency of rust and fouling protection, enhanced service life and reduced power intensity. 4 cl, 3 dwg , 1 tbl
