Driving greenfield projects forward with fiber optic CUI monitoring

Corrosion Under Insulation (CUI) is a continues challenge for industrial assets. Even with high-quality materials and protective coatings, insulated equipment remains at risk from moisture, temperature changes, and chemical exposure, all of which can accelerate corrosion. For operators starting new projects, adding monitoring solutions from the beginning can save costs and help prevent unexpected downtime.

The importance of CUI monitoring in greenfield projects

Greenfield projects offer a unique opportunity: designing assets for long-term reliability from day one. Traditional inspection methods, such as ultrasonic testing or visual inspections, provide only occasional snapshots, leaving gaps in risk management. Continuous monitoring, on the other hand, delivers real-time insight into corrosion development, helping teams address potential issues before they become serious problems.

Why fiber optic technology leads the way

Fiber optic monitoring has become the preferred approach for CUI detection. Unlike conventional sensors, fiber optic cables provide distributed measurements across pipelines, tanks, and other insulated equipment. This approach offers several key advantages:

• Wide coverage: Fiber optic cables can monitor long stretches of equipment, leaving no areas unchecked, without the need to remove insulation or cladding.

• Resilience in harsh conditions: They withstand extreme temperatures, and chemical exposure.

• Real-time alerts: Immediate notifications allow targeted maintenance, reducing downtime, improving safety and avoiding costly repairs.

Integrating monitoring into project design

The real benefits of fiber optic CUI monitoring are achieved when it’s part of the greenfield project plan. Thoughtful sensor placement, alignment with insulation design, and integration with asset management systems all ensure reliable data and insights. Early planning simplifies installation and maximizes the value of the monitoring system throughout the asset’s life.

Conclusion

Proactive CUI management is essential for operators who want to protect assets, improve safety for employees and maximize ROI. By incorporating fiber optic monitoring into greenfield projects, organizations gain clear visibility into corrosion risks and can take action before problems arise. With the right expertise, continuous CUI monitoring becomes a key pillar of asset integrity, helping operators safeguard their investments over the long term.
