BERLIN: Berlin said Friday it had taken control of the German operations of Russian firm Rosneft to secure energy supplies which have been disrupted after Moscow invaded Ukraine.

Rosneft’s German subsidiaries, which account for about 12 percent of oil refining capacity in the country, were placed under trusteeship of the Federal Network Agency, the economy ministry said in a statement.

“The trust management will counter the threat to the security of energy supply,” it said.

The move covers the companies Rosneft Deutschland GmbH (RDG) and RN Refining & Marketing GmbH (RNRM) as well as three refineries: PCK Schwedt, MiRo and Bayernoil.

Fears had been running high particularly for PCK Schwedt, which is close to the Polish border and supplies around 90 percent of the oil consumed in Berlin and the surrounding region, including Berlin-Brandenburg international airport.

The refineries’ operations had been disrupted as the German government decided to slash Russian oil imports, with an aim to halt them completely by year’s end.

By taking control of the sites, the German authorities can then run the refining operations using crude from countries other than Russia.
