Associated Disaster Risk of Inadequate Corrosion Control (Cathodic Protection) on Pipelines in Port Harcourt, Nigeria: A Quantitative Approach

Corrosion in pipelines is one of the significant challenges faced by oil and gas industries which has led to the need for corrosion preventive measures or management when dealing with pipelines as a transportation system in any industry. Through a quantitative approach, the associated disaster risk of inadequate corrosion control (cathodic protection) on pipelines in Port Harcourt, Nigeria, was investigated. One hundred (100) respondents (MNOCs staff) were involved, and a questionnaire was adopted for data collection. The finding revealed that pipeline leakages are attributed to cathodic rupture, corrosion, vandalization, rust, age,wear, and combined action of corrosion and vandalism. Among other risks, disaster risk associated with production and environmental impact was rated highly. As a preventive measure, the respondents indicated that Cathodic Protection System (CPS) prevents disasters associated with pipeline leakage due to the corrosion effect. Maintenance practices are carried out on the CPS annually. In conclusion, CPS endure risks are minimized and serve as a proven proactive measure to prevent pipeline corrosion.
