This study aims to find out the best anode location for buried pipelines. Numerical simulation program known as CATPRO(Elsyca, Belgium) were used for confirming the best location of anodes and the effects of impressed current cathodic protectionsystem. Applied conditions for numerical simulation were similar to on-site environmental conditions for optimal application ofcathodic protection system. Used criterion of cathodic protection was NACE SP 0169, which describes that minimum requirement forcathodic protection is -850mV vs. CSE. Various layouts for anodes’ installation were applied, which were distance between anodes,anode installation location, and applied current. The areas where cathodic protection potential was lower than -850mV vs. CSE waslimited up to 50m from anode installation locations. It was founded numerical analysis obtain cost-effective and efficient cathodicprotection methods before design and application the impressed cathodic protection system to on-site environment.
