A Game-Changer in Preventing Corrosion and Measuring Wall Thickness for the Oil and Gas Industry: Online non-intrusive corrosion monitoring.

As the oil and gas industry continues to expand and evolve, the challenge of maintaining the integrity of pipelines and other assets becomes increasingly critical. Corrosion is one of the major challenges facing the industry. Preventing corrosion is essential for asset safety and the environment, as well as for operational cost and efficiency.

One of the most effective methods for preventing corrosion is non-intrusive corrosion monitoring. Non-intrusive corrosion monitoring lets you monitor and prevent potential corrosion challenges in your pipes and pipeline. In recent years, online non-intrusive corrosion monitoring has emerged as a game-changer in this field.

What is Online Non-Intrusive Corrosion Monitoring?

Online non-intrusive corrosion monitoring involves using sensors or monitoring systems to continuously measure the thickness of pipes or other structures in real-time. These sensors can be installed on the exterior of the asset, typically using clamps or other non-intrusive mounting methods that don’t require drilling into the pipe or vessel. The sensors use various non-intrusive techniques to measure the thickness of the metal, such as ultrasonic testing or electromagnetic induction.

The data from these sensors is typically transmitted to a central monitoring system or control room where it can be analysed and displayed in real-time. This allows operators to detect changes in corrosion rates or patterns immediately and take corrective action before more serious damage occurs.

Online vs Offline Non-Intrusive Corrosion Monitoring

Online non-intrusive corrosion monitoring, on the other hand, provides real-time data on corrosion rates and pipe thickness without the need for manual data collection. This approach uses sensors and data loggers that are permanently installed on the asset, allowing for continuous monitoring and detection of any changes in corrosion rates or pipe thickness. Online monitoring is more effective than offline monitoring for detecting localized corrosion or rapid changes in corrosion rates that may be missed with periodic measurements.

Additionally, online monitoring eliminates the need for manual data collection and can reduce labour costs and safety risks associated with accessing pipes and vessels for data collection. Overall, while offline monitoring may be effective for identifying trends over time, online monitoring provides real-time data and more comprehensive information on the health of the asset.

Benefits of Online Non-Intrusive Corrosion Monitoring

Online non-intrusive corrosion monitoring has several advantages over offline monitoring. Here are some of the key benefits:

Continuous monitoring: Online monitoring allows for continuous monitoring of the asset, providing a more complete picture of corrosion rates and patterns over time.

Rapid detection of changes: Online monitoring can detect rapid changes in corrosion rates or localized corrosion that may not be captured with periodic measurements.

Reduced labour costs and equipment downtime: Online monitoring does not require shutdowns or interruptions to collect data, reducing labour costs and equipment downtime.

Improved safety: Online monitoring can reduce risks and hazards to inspection personnel because several non-intrusive inspection techniques can be performed remotely. No cleaning and emptying of metal vessels is required for the inspection.

Conclusion

Online non-intrusive corrosion monitoring is a powerful tool for maintaining the integrity of oil and gas infrastructure and preventing costly and dangerous failures. By providing continuous, real-time data on corrosion rates and patterns, operators can take proactive measures to prevent corrosion and extend the life of their assets. With the many benefits of online non-intrusive corrosion monitoring, it is no wonder that it has become a game-changer in the industry.
