Introduction Cathodic protection may be defined as a means of rendering a metal, immersed in an electrolytically conducting environment, immune from corrosion by causing direct current electricity to flow from the environment into the metal. This paper is not intended to elaborate in depth on the application of cathodic protection, which is exhaustively covered elsewhere, but in general the technique is commonly applied to pipelines, storage tanks, jetties, ships and offshore platforms, where the electrolyte is soil or natural waters. See Figure 1 (appendix I).
