Corrosion failures have been experienced in sea water systems made of highly alloyed stainless steels in the offshore industry. This paper presents the protection method called RCP (Resistor-controlled Cathodic Protection) as a means to avoid the problem in a simple and economic way. The principles of the method are outlined and its use in various environments is discussed. Cathodic polarisation data obtained by long term testing of a highly alloyed stainless steel in chlorinated sea water are presented. Reliable data of this type are needed for the design of RCP systems. The RCP method is now established as a proven technology and the system is marketed worldwide by CorrOcean an SINTEF Corrosion and Surface Technology.
