Cathodic Protection in Onshore Pipeline: Case Studies on Corrosion-Induced Leaks and Environmental Impacts

The transportation of oil through onshore pipelines is a critical operation that requires stringent safety measures to prevent leaks, which can have severe environmental and economic consequences. This study investigates the role of cathodic protection in preventing external corrosion of pipelines, focusing on three case studies involving different failure scenarios. Key findings indicate that factors such as changes in soil resistivity, interference from nearby electrical infrastructure, and inadequate maintenance significantly contribute to cathodic protection failures, leading to pipeline leaks. The results underscore the importance of proper system design, continuous monitoring, and maintenance to mitigate the risk of corrosion and ensure safe pipeline operations. This study provides valuable insights into enhancing the reliability of cathodic protection systems in onshore pipeline networks.
