How calcareous deposits formation in seawater influences the performance of a galvanic cathodic protection (CP) system in seawater. Coupling current measured. A resistance set between the cathode and the anode simulated circuit resistance of CP. Steel cathode potential over immersion time. Calcareous deposits analyzed by X-Ray Diffraction.
An effective and efficient impressed cathodic protection system by laying a continuous shallow anodes bed in close proximity to the tank foundation. Some of the merits of this installation include elimination of shielding effects or interference from other structures and uniform protection of the entire tank bottom.
