17 years at TotalEnergies, including 10 years on Refinery sites working on DCS System (add-in new units, revamp on DCS system,...) and Advanced Process Control (Deployment for 2 major unit Fluid catalytics cracking and Vacuum Distillation Unit). During this time, I was the Piadmin for the Local System. Since 7 years, I'm on the Centrale IT Team of the Company, as the main contact for PI Systems for all the downstream and Polymers sites. I developped this vision and usage of the modern PI System including AF Usage.
