Notes

The January 2026 news confirmed gas turbine restart at Fos refinery, indicating completion of that phase of maintenance. April 2026 news shows no current disruptions at the facility. The refinery appears to have resumed normal operations post-maintenance, though may still be ramping up to full capacity after extended maintenance period that began in December 2025.
