Many existing small fuel tank farms still have not cathodic protection. New revised environment and safety standards force the operator to install cathodic protection for their system. Limited owned expensive land from one hand neighbor metallic underground piping such as fire fighting water which can interfere with CP system from other hand are challenging problem in this field. As the current and potential distribution tests are not possible due to lack of any permanent reference electrode beneath the tank bottom plate and also horizontal or angel drilling is not economically feasible for these small tank farms utilizing the boundary element method (BEM) the important factor for a cathodic protection system such as type of ground bed semi deep deep distributed anodes around the tank's perimeter and concentrated surface ground bed the location of the ground bed and optimum current that can polarizes the surface potential to protection potential have been simulated for tank bottom plate in contact with soil and neighbor under ground piping. Then the results were illustrated in some graphs that showing the potential distribution in tank bottom and pipe's surface. The results show appropriate performance of semi deep ground bed from potential distribution and economical point of view. Finally the best anodic current and location of anodes was found by simulated model too.

 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.
