The cathodic protection system analysis as tools for one-dimensional pipelines and riserswas modeled and derived incorporating the relevant resistance terms. The new expres-sion pertains to pipelines with superimposed anodes. Comparisons were made betweenthe potential attenuation projected by the new expression, the classical equation of Uhligand the boundary element modeling technique. It was confirmed that the newly derivedequation is more conservative than the boundary element modeling technique due to itsconsideration of the metallic path resistance and the Uhlig equation because of its consid-eration of the anode resistance.
