New Best Practices for Corrosion Under Insulation (CUI) Monitoring Released – CUI RP 101

[18th December 2024]: A new set of best practices created specifically for the Oil, Gas and
Petrochemical industries has been released today, giving guidance on the deployment,
usage, inspection strategies and maintenance of Corrosion Under Insulation (CUI)
monitoring systems. This Recommended Practice is referred to as CUI RP 101 Issue 1.

The Recommended Practice document, which includes contributions from experienced
users throughout the industry, including Aramco, Dow, INEOS and Chevron, contains best
practices from asset selection to the use of maintenance management systems, inspection
strategies and economic justification principles. It has been developed to enable Asset
Owners to optimise inspection and repair strategies and enhance CUI management
processes with continuous monitoring systems in the arsenal.

CUI costs the industry billions of dollars every year to mitigate the risk and repair the
damage it causes to assets. Unmanaged CUI can result in leaks, leading to process safety
incidents, severe harm to the environment, high unexpected repair costs and operational
downtime.

Continuous monitoring systems offer remote detection of localised corrosion and moisture
on an asset, while also providing corrosion rates. This empowers Asset Owners to make
informed decisions on where and when to conduct repairs, leading to significant cost
savings, reduced safety hazards, and minimised environmental risks across the industry.

The key principles outlined in the guidance include:

– The technology behind a CUI monitoring system.
– Asset selection criterion.
– The process to be used for technical justification, validation and qualification.
– Use of remote monitoring in the different inspection strategies.
– Organisational recommendations.

Theo Knijff, independent consultant from KAI-Con, co-author of the guidance and Chair of
the Recommended Practice Committee, said: “Unmanaged CUI poses a significant risk to
the mechanical integrity of insulated carbon steel equipment and piping, and repairing the
damage it causes has significant cost implications.

“By implementing a continuous CUI monitoring system, Asset Owners can take proactive
steps to prevent CUI from becoming a substantial issue, minimising the risk of process
safety incidents and costly repairs, while also optimising downtime.

“We have developed the new best practices as an essential toolkit for Asset Owners and
believe it will play a pivotal role in transforming the way the industry manages its assets in
the future, enhancing asset management strategies and ensuring the longevity of critical
infrastructure to drive operational efficiency.”

About CorrosionRADAR:

CorrosionRADAR is a global solution provider of CUI risk monitoring, combining the power of
product, data, and expertise for the most accurate prediction of when and where corrosion
will occur in critical energy infrastructure. It is used by some of the world’s largest energy
companies and offers significant competitor advantages over traditional risk monitoring
approaches.

The solution is predictive, using data analytics software to provide a dynamic risk
assessment for each asset location. It is more comprehensive, offering both corrosivity and
moisture rate monitoring over a much longer range. Additionally, it provides a higher-quality
prediction of CUI risk by being embedded into the assets rather than the insulation.
CorrosionRADAR is based in Cambridge, UK and counts Saudi Aramco Ventures, Dow,
Kanoo Ventures and Mercia among its shareholders
