Two main processing units stopped operating at Russia’s Ryazan oil refinery, which supplies fuel to Moscow, after a Ukrainian drone attack last weekend. CDU-6 and CDU-4 were taken offline after a fire broke out following the attack.
CDU-6, which accounts for nearly half of the refinery’s capacity, can process 8 million metric tons of oil a year, or about 160,000 barrels per day. CDU-4 has an annual processing capacity of 4 million metric tons.
Unit outages could last longer
The facility’s third main unit, CDU-3, has also been out of operation for maintenance since mid-May. Repairs to the units damaged in the attack could take several weeks.
The Ryazan refinery was previously targeted by drone attacks in May and July. Operations at the facility halted for about two to three weeks after the July attack.
New blow to Russia’s fuel capacity
Ukraine has stepped up attacks on Russian oil refineries and oil supply routes since the spring. The attacks are believed to aim to reduce revenue from rising oil prices, while production has halted at some facilities and capacity has been reduced at others.
