Key Highlights

  • Maintenance begins in March with phased shutdowns of unspecified units at the Normandy refinery.
  • The event includes inspections and upgrades to improve energy efficiency, environmental performance, and safety standards.
  • The refinery will continue to supply products to customers without interruption.
  • This is the first major turnaround under North Atlantic Group’s ownership, following its acquisition in November 2025.

Canada-based North Atlantic Refining Ltd. France-based subsidiary North Atlantic France SAS is undertaking planned maintenance in March at its North Atlantic Energies-operated 230,000-b/d Notre-Dame-de-Gravenchon refinery in Port-Jérôme-sur-Seine, Normandy.

Scheduled to begin on Mar. 3 with the phased shutdown of unidentified units at the refinery, the upcoming turnaround will involve thorough inspections of associated equipment designed for continuous operation, as well as unspecified works to improve energy efficiency, environmental performance, and overall competitiveness of the site, North Atlantic Energies said on Feb. 16.

Part of the operator’s routine maintenance program aimed at meeting regulatory requirements to ensure the safety, compliance, and long-term performance of the refinery, North Atlantic Energies said the scheduled turnaround will not interrupt product supplies to customers during the shutdown period.

While the company confirmed the phased shutdown of units slated for work during the maintenance event would last for several days, the operator did not reveal a definitive timeline for the entire duration of the turnaround.

Further details regarding specific works to be carried out during the major maintenance event were not revealed.

The upcoming turnaround will be the first to be executed under North Atlantic Group’s ownership, which completed its purchase of the formerly majority-owned ExxonMobil Corp. refinery and associated petrochemical assets at the site in November 2025.
