Customers often need information necessary to assist them with many cathodic protection aspects.  The science of cathodic protection, or C.P., dictates that many technical considerations are involved in protecting an underground or underwater structure.  These considerations include electrolyte resistivity, structure material, coating performance, electrical isolation, current demand, proximity to other structures, environmental issues, temperatures, and more.  Therefore, C.P. is not a “cookie cutter” solution and guessing does not provide sound technical solutions.
