Deteriorating pipeline coating systems have been a dilemma in the industry for many years. The interaction between coatings and cathodic protection (CP) is based on the type of coating and the amount of deterioration. There are two primary strategies to approach the problem: recoat, which is very expensive and may require taking the line out of service and cause loss of revenue; or install additional conventional CP groundbed systems. This article presents a state-of-the-art groundbed system using close-coupled conductive polymeric cable anodes that eliminate the problems of conventional groundbeds.
