Prevention of Puma Energy facilities/structures in East and West New Britain Provinces of Papua New Guinea from
corrosion has solely been based on sacrificial anodes. According to tests and data collected, it has proofed that
sacrificial anodes cathodic protection (CP) system do not effectively protects the structures from corrosion. This was
one of the main problems faced by Puma Energy PNG Limited across other CP terminals in Papua New Guinea. The
sacrificial anodes system used by the company has ineffectively protected the structure due to its weak potential
difference which solely emits from natural anodes (elements) without any external power supply source to effectively
drive the current through.
According to the research and study, the possible optimum replacement option is impressed current cathodic protection
(ICCP). The impressed current cathodic protection system is one of the best methods of protecting and preserving
steel structures from corrosion. The impressed system potential is reinforced by external power supply source where
anodes potentials further pushes protective current supplied from rectifier units and drive through electrolyte which
profoundly protected the structure.
