Optimizing Gas Pipeline Integrity with Cathodic Protection | EARTHRES

Project Background

Maintaining the mechanical integrity of natural gas pipelines is critical for ensuring the safety, reliability, and efficiency of energy infrastructure. Corrosion poses a significant challenge to metal gathering and transmission lines, which often span hundreds or even thousands of miles, both above and below grade. Cathodic protection (CP) systems serve as an essential defense against this threat, diverting corrosion from the pipeline to a sacrificial anode. However, these systems require constant vigilance, including routine monitoring, inspections, and adjustments, to remain effective.

EARTHRES helped a client address significant issues within their CP system, ensuring optimal performance and mechanical integrity while reducing risks and costs associated with pipeline downtime and repairs.

The Results

By partnering with EARTHRES, the client achieved several impactful outcomes that enhanced the safety, reliability, and cost-effectiveness of their operations.

Key Benefits:

1. Ensured Corrosion Protection: The newly designed and optimized CP system safeguarded the pipeline from corrosion, eliminating the immediate risks of mechanical failure and pipeline downtime.
2. Reduced Maintenance Burden: The client could now focus on routine operations without dedicating non-CP-certified staff to system management. EARTHRES’ expertise ensures that the CP system continues to function effectively under their oversight.
3. Cost Savings: By preventing potential corrosion issues, the client avoided substantial repair costs and minimized the risk of unplanned downtime, resulting in long-term cost savings.
4. Enhanced Knowledge Transfer: Through EARTHRES’ staff training, the client gained a better understanding of CP system operation, enabling more informed decision-making.

Routine monitoring and precise field interventions are critical to preventing small issues from escalating into major problems.
