Predictive Maintenance: TotalEnergies RAID at the forefront

Rotating machines: at the heart of industrial performance

Rotating machines are essential to the proper functioning of industrial facilities at TotalEnergies and play a key role in terms of safety, performance and energy efficiency. From electricity production to fluid circulation, their reliability determines process continuity and help limit the environmental impact. At CSTJF in Pau, thanks to the expertise acquired in advanced monitoring and predictive maintenance, rotating machines are a real lever for decarbonisation and operational excellence.

At TotalEnergies, rotating machines play an essential role, constituting the real mechanical heart of industrial facilities. Pumps, compressors, gas or steam turbines, motors and alternators are found throughout all of the Company’s sites, including oil and gas platforms, refineries, petrochemical plants, terminals and new multi-energy activity facilities.

They are essential to the proper functioning of processes, ensuring fluid circulation, gas compression, electricity production and the driving of critical equipment. Their reliability therefore is crucial: the shutdown of a single major rotating machine is all that’s needed to halt an industrial process, which in turn has a direct impact on safety, the environment and economic performance.

Beyond their operational role, rotating machines are now a strategic performance and decarbonisation lever. Their energy efficiency directly influences energy consumption, CO₂ emissions and flare gas volumes. Optimising the functioning of compressors, improving the efficiency of turbines and detecting discrepancies in performance thus helps to reduce the carbon footprint of industrial facilities. These actions fall within TotalEnergies’ aim to reconcile operational excellence and the energy transition.
 

RAID, advanced technology at its finest

To meet these challenges, the Company has significantly invested in advanced monitoring and predictive maintenance. At the Jean Féger Scientific and Technical Centre (CSTJF) in Pau, the RAID (Remote Assistance, Intervention & Diagnostics) team continuously analyses data from over 33,000 sensors distributed on around 800 rotating machines worldwide. Vibrations, temperature, pressure and speed are monitored remotely to anticipate failures before they become critical, improve safety at facilities and prevent unexpected shutdowns. This unique expertise supports the performance of the Company’s industrial sites worldwide in the long term.

To prevent machine failures and production shutdowns, TotalEnergies decided to undertake monitoring in-house, a task which was previously performed mostly by service providers. The results were immediate. Several months later, the implementation of RAID already helped to better predict and anticipate breakdowns. In 2021, the RAID team centralised the monitoring of both tools used for the Company’s machines (a tool for the Exploration and Production subsidiaries and a tool for the Refining & Chemicals sites). In 2025, a significant milestone was reached with the standardisation of monitoring using a shared tool for all branches.

"With over 10 years of experience in remotely monitoring machines installed at the Company’s production sites, our analyst team processes alerts on equipment located thousands of miles from Béarn!", Fabrice Leclercq, Head of the RAID team explains.

Decoding each alert

The centralisation of data from subsidiaries at CSTJF has led to revisions to some of the Company’s maintenance strategies, which have become partially predictive and streamlined at all sites, improving the sharing of good practices.

The software used at RAID collects data from machines and provides alerts thanks to a prediction algorithm based on previous operation logs. When the equipment indicators “turn red”, the RAID analysts contact the site’s maintenance team. The nearby presence of TEC/MEC technology experts allows analysts to refine their diagnostics and provide production sites with targeted responses to explain deviations and define mitigating measures.

"We talk about early detection, which makes it possible to monitor gradual deteriorations and identify the risk of failure. From an operational and business point of view , it is better to anticipate and plan a shutdown rather than experience a failure”, Fabrice Leclercq insists.

Nowadays, RAID’s expertise continues to develop in line with the Company’s strategy, also focusing on combined-cycle power plants so that the expertise acquired in oil and gas benefits other activities at TotalEnergies.
