Abstract

Cathodic protection is one of the methods for controlling corrosion. The system applied to this jetty is Impressed Current Cathodic Protection (ICCP). This system works by giving current through an external source so this method is called the impressed current method
The installation of the ICCP cathodic protection system on the Jetty system facilities has been completed, this ICCP protection system has a design minimum of 10 years (lifetime to protection). All results of potential measurements on test & commissioning have met the protection criteria according to ISO 15589-2 standard. The negative potential value that can be accepted is min -850 mV (CSE) or -800 mV (Ag / AgCl), from the measurement results the range obtained is -842 mV to -1197 mV against Ag / AgCl. Inspection of 4 TR, the total output current is still below capacity (safe). Based on the results of joint inspection and commissioning, the ICCP cathodic protection system has been functioning properly in accordance with NACE SP0169-2007 and ISO 15589-2 standards and is acceptable.
The recommendation to keep maximizing the installed ICCP cathodic protection system is to have to check the current and potential on the TR every month, to find out the condition of the protection system functioning properly.
