The Influence of a Grounding System on Cathodic Protection

An article in December 2014's MP magazine looked at the effect of grounding on the cathodic protection (CP) potential distribution at an oil station, which had been studied using BEASY's corrosion and cathodic protection simulation software.

Influences from four factors were analysed: grounding system material, relative position between the grounding conductor and the pipeline, and length and buried depth of the grounding conductors. CP designs with and without grounding were compared.
