French oil and gas company Total has shut down some units at its 247,000 barrels-per-day Gonfreville refinery in northern France following a technical incident, a spokesman said on Monday.
The spokesman said the incident occurred in a steam producing unit whose backup was under maintenance.
"The site decided to protectively shutdown some of its units," he said, adding that it was still unclear how much production was affected and when the units would resume.
