Close distributed anode CP system are ideal for protection of existing bottom plates of Above ground storage tanks located near congested plant piping and grounding grid in the major Oil/gas producing company. Comparative studies are carried out with anodes distributed along the periphery to anodes grid beneath the tanks. CP Protection levels along the bottom surfaces with actual field measurement data’s are compared in this paper for both anode orientations.
