Russia’s top oil port in the Baltic Sea, Primorsk, resumed loading days after it came under attack from Ukrainian drones, although Bloomberg notes that the company that pipes crude there said it is trying to divert barrels elsewhere because of the incidents.

The Minerva Georgia, a Suezmax-class vessel capable of hauling about 1 million barrels of crude, berthed on Wednesday. Another, the Anlan, is scheduled to depart Thursday having been there for several days.

Ukraine has stepped up attacks on Russian oil infrastructure to prevent Putin from benefiting from soaring prices. It also targeted the port of Ust-Luga this week, as well as the Kirishi oil refinery. Transneft, Russia’s pipeline operator, aims to divert flows away from the Baltic ports, Interfax reported.

Kiev’s moves seek to disrupt the flow of Russian petroleum at a time when the Iran war has already caused an unprecedented oil-supply shock. A Turkish oil tanker carrying Russian oil also came under drone attack in the Black Sea.
