Application of solar photovoltaic electricity in unravelling the effects of coating defects on cathodic protection parameters of buried pipeline

Abstract Corrosion management in some remote locations such as Niger Delta region of Nigeria, is at risk uncertainty constant power supply. Thus, solar photovoltaic (PV) presents a sustainable alternative to conventional fossil energy mitigating pipeline failure, associated human and material harzards other environmental exposures. Coating defects takes place when the surface structure cathodically exposed. An epoxy coating was applied on X65 carbon powered with four (4) PV modules charge 200Ah battery generate direct current (DC) detect initiated coated pipe. Linear Polarization Resistance (LPR) technique adopted assessing cathodic protection (CP) parameters The result shows that flow decreased an increase size defect. CP found be 12354263.07 Ohm.cm2 compared no 87174 0.1 cm 2 scratch size. By implication, application absence observed significantly current. This otherwise known overprotection, situation enhances hydrogen embrittlement disbondment.
