Paris, France – February 2026 – TotalEnergies, a global leader in oil and gas, has successfully deployed ABB PM864AK01 3BSE018161R1 Processor Modules to upgrade the distributed control system (DCS) of its petrochemical plant in Lavera, France. The deployment, completed in Q1 2026 after a three-month pilot, addressed critical issues with legacy processor modules, including frequent system crashes, slow data processing, and inability to support hardware redundancy. Six months post-implementation, the plant has achieved a 58% reduction in unplanned downtime, a 42% improvement in data processing speed, and 99.99% operational reliability—key milestones in optimizing petrochemical production efficiency and safety.
The Challenge: Legacy Processors Hinder Critical Petrochemical Operations
TotalEnergies’ Lavera plant produces over 1.2 million tons of ethylene and propylene annually, relying on a complex DCS to control catalytic cracking, distillation, and hydrogenation processes. These processes operate 24/7 and require uninterrupted control, as even a 1-hour shutdown can result in €250,000 in lost revenue. Prior to the upgrade, the plant used legacy processor modules installed in 2017, which lacked redundancy support and struggled to handle the plant’s 8,000+ I/O points and complex control loops.
The outdated processors experienced 18-22 system crashes per year, leading to 120+ hours of unplanned downtime and €30 million in annual revenue losses. Their slow processing speed (0.8 ms per 1000 boolean operations) caused delays in responding to process deviations, increasing safety risks in the hazardous petrochemical environment. Additionally, the legacy modules were incompatible with the plant’s ABB Ability™ 800xA DCS, requiring manual data transfer and limiting real-time monitoring capabilities. Maintenance teams also spent 12+ hours weekly troubleshooting processor-related issues, driving up operational costs.
“Uninterrupted control is non-negotiable in petrochemical production, where every minute of downtime costs hundreds of thousands of euros,” said Jean Dubois, Plant Manager at TotalEnergies Lavera. “Our legacy processors were a liability—frequent crashes, slow response times, and no redundancy left us vulnerable to production losses and safety risks. We needed a high-performance processor that could integrate seamlessly with our 800xA DCS, support redundancy, and handle our complex control needs reliably.”
The Solution: ABB PM864AK01 3BSE018161R1’s Redundancy and Processing Power
After evaluating processor modules from ABB, Emerson, and Yokogawa over 10 weeks, TotalEnergies selected the ABB PM864AK01 3BSE018161R1 for its native 1:1 hardware redundancy, fast processing speed, and deep 800xA DCS integration. The deployment followed a phased approach to avoid disruption: first, a pilot on the ethylene cracking unit during scheduled maintenance; second, training 45 engineers and technicians on module configuration and redundancy switching; and finally, full rollout across all plant sections over four months with ABB’s on-site support.
Key features of the ABB PM864AK01 3BSE018161R1 that solved TotalEnergies’ challenges include:
- 1:1 Hardware Redundancy: The module supports hot-standby redundancy with <100ms bumpless failover, ensuring the backup processor takes over instantly if the primary unit fails—eliminating downtime from processor faults.
- High-Speed Processing: Equipped with a dual-core processor, it handles 1000 boolean operations in just 0.15 ms, 5x faster than legacy modules, enabling real-time response to process deviations.
- Deep 800xA Integration: As a core component of ABB’s AC 800M controller family, it integrates seamlessly with the 800xA DCS, enabling real-time data sharing and remote monitoring without manual transfer.
- Robust Industrial Design: Rated for 0°C to +60°C operating temperatures and IP20 protection, it withstands the harsh petrochemical environment, with a 30-year MTBF for long-term reliability.

“The ABB PM864AK01 has been a game-changer for our Lavera plant,” said Jean Dubois. “The redundancy feature alone eliminated most unplanned downtime, while the faster processing speed has made our operations safer and more efficient. We’re now looking to deploy this module across all our European petrochemical facilities by 2028.”
Sophie Laurent, ABB’s Global Product Manager for Process Control Modules, added: “Petrochemical plants need processors they can trust to keep critical operations running. The PM864AK01’s redundancy, speed, and 800xA integration make it ideal for these demanding environments, and TotalEnergies’ success is a testament to its value.”
