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.
Analysis of the Sunde’s equation for multiple electrodes in horizontal configurationsis done in order to show that this equation cannot be used in the case of typical cathodic protection design. An accurate approach to horizontal anode groundbed design and understanding of the theory behind groundbed resistance equations.
