SINGAPORE: Engen Petroleum has partially shut its 125,000 barrels-per-day (bpd) refinery in South Africa as maintenance cuts crude oil supplies, a company spokeswoman said on Wednesday.

The Durban single buoy mooring, which brings crude oil into the refinery, will be out of commission for part of May, spokeswoman Tania Landsberg said in an statement emailed to Reuters.

As a result, Engen will shut some unspecified units at its refinery between May 5 and May 24 for maintenance, she added.

The refinery will continue to operate at a reduced run rate, Landsberg said, without providing further details.
