- The context
- An industrial chemicals / energy site with a continuous process, classified Seveso, with several units (utilities, fermentation, purification). The goal: monitor equipment and capture data that human rounds miss, without exposing teams to hazardous zones.
- The lived pain
- A human round can't hear or see everything. An air leak at 80 kHz is inaudible, even with the plant shut down. An unhooked extinguisher, a faulty sensor: the anomaly goes unnoticed until the next check. To locate its leaks, the site goes as far as shutting the plant for two months every three years. And some checks expose people: for an ammonia leak at the sphere, someone is sent in a hazmat suit today.
- The approach
- Definitely not "a robot everywhere". Around thirty use cases were screened (value, safety impact, energy impact, effort), and everything already covered by a fixed sensor was deliberately dropped. The robot arrives under supervised autonomy: each mission is validated by a lead before running on its own, it's built into the site's safety induction with an HSE risk assessment, and human rounds don't disappear. A large part of the work is acceptance: team presentations, an internal contest to name it, and even a "robot shower" to get the whole organisation on board.
- The resultdeployment under way
- Let's be clear: the deployment is just starting, there's no measured result on this site yet, and we won't invent a figure. Concretely, the robot runs rounds scheduled like meetings: thermal camera (hot spots), acoustic camera (inaudible air leaks), gauge and display reading, gas detection, spotting objects out of place. For a sense of scale, the maker AnyBotics documents, on its reference chemical sites, typical benefits (early detection, tamper-proof timestamped readings, access to hazardous zones) and, on one plant, up to +1.5% availability. Those are its figures, not ours yet.
- What it changes for the team
- No one is replaced: staff are getting scarce for inspections in hazardous zones. The robot takes on the repetitive task, without complaining and without faking a reading, and people go back to where intuition is needed. At a demonstration, employee representatives were in fact favourable to its rounds.
- The limit, said plainly
- Where a value already reaches the control room via a fixed sensor, the robot has no business being, and it was dropped from cases already instrumented. It earns its place through mobility and versatility, one robot covering several units and several types of measurement, never as one more sensor. And until we've measured here, we speak of expected benefits, not proven ones.
