Both crude distillation units at BP's Rotterdam oil refinery, one of Europe's largest, are currently offline, an energy consultancy confirmed on Tuesday. This dual shutdown has sparked concerns about refined product supply from the crucial facility, which boasts a total crude processing capacity of 400,000 barrels per day (bpd).

According to energy consultancy Wood Mackenzie, a 200,000 bpd crude unit at the refinery ceased operations on the morning of June 3. While the exact cause of this latest shutdown remains unconfirmed, Wood Mackenzie anticipates an imminent restart, suggesting it is likely an unplanned outage.

This recent incident follows a longer-term disruption at the refinery. Another 200,000 bpd crude unit at the Rotterdam site has been offline since May 1. Wood Mackenzie noted that planned maintenance work for this unit was initially expected to commence in April.

Further impacting the refinery's output, a 32,000 bpd catalytic reformer unit, responsible for producing gasoline blending components, was also shut down by BP on April 16, as per Wood Mackenzie's data.

BP has not yet responded to requests for comment regarding the current operational status of its Rotterdam refinery. The ongoing outages at such a significant European refinery could have implications for the regional supply of various refined petroleum products, including gasoline and diesel. Market observers will be closely watching for updates on the restart of these crucial units.
