Historically, cathodic protection (CP) surveys of offshore platforms have been comprised of a number of steel to seawater potential measurements recorded at selected points on or around the structure. Little or no emphasis has been placed on evaluation of the “resilience” of the CP system; i.e. how hard is the system working, how efficiently, and how much longer will it continue to provide efficient protection. The new approach, which has been used by some operators since 1989 in the Gulf of Mexico, addresses some of these areas without significant increase in the time required to perform the inspection.
