| Summary: | Cathodic protection (CP) is the most effective method for protecting
petroleum facilities against corrosion. As part of this protection, care should
be taken to continuously evaluate the existing system in order to maintain
the system in favorable conditions. The subject of the paper’s research is an
oil plant for the transportation of oil derivatives located at the Brega
company in Tobruk, Libya. In the present work, a case study on how to
evaluate the CP system for an existing company for petroleum
transportation is considered. The procedure was planned in three steps. The
first step is a historical survey of the CP system from when the company
started. The second was a diagnostic analysis study of the problem and how
to fix it along the system. The third is the conclusions and recommendations
regarding the measures for evaluating the CP system without stopping
production.
