A new approach on troubleshooting of cathodic protection: A case study

• Current work offers a new approach in CP troubleshooting regarding to reversal currents.
• One of important subject in cathodic protection troubleshooting is the amount of reversal current.
• Measuring potentials of protected structures is not sufficient and monitoring of reversal current as schedule is essential.

The aim of this paper is to suggest an effective procedure to eliminate a major deficiency in impressed current cathodic protection (CP). Current work describes performed activities through jetty cathodic protection troubleshooting as a case study. Although CP troubleshooting is straightforward, sometimes it is very complicated and confusing. To eliminate the appeared imperfection, different procedures were carried out; the root cause of the trouble in the system was shown to be in reversed current. Here the current which passed throughout installed junction were measured to survey reversed current. Current work offers a new approach in CP troubleshooting.
