The suspension of oil product exports through the Baltic port of Ust-Luga following drone attacks on March 25 may force major refineries in the European part of Russia to slash production. According to Reuters, damaged infrastructure has made it impossible to export fuel, pushing the country’s largest plants toward a total shutdown.
The Logistics Deadlock:
- Infrastructure Paralysis: The UAV strikes damaged the railway overpass used for unloading fuel tanks at the “Ust-Luga Oil” terminal. Acceptance of products from the Kirishi (Kinef), Yaroslavl (YaNOS), Moscow, and Ryazan refineries has been completely halted.
- The Fuel Oil (Mazut) Factor: These refineries produce between 18% and 35% fuel oil as a byproduct of crude processing. There is no domestic demand for mazut in Russia — it was almost entirely exported through the Baltic (over 14 million tons annually from these specific plants).
- The Threat of Shutdown: Storage tanks at the refineries are reaching full capacity within days. If the mazut cannot be moved, the technological cycle requires an immediate reduction in crude processing, leading eventually to a complete halt of the units.
Analytical Summary:
The situation in the Baltic is evolving into the “economic strangulation” of the Russian fuel market through its refinery byproducts.
The Domino Effect on Gasoline: The primary issue is not a shortage of fuel oil itself, but the technological interconnectedness of the refining process. You cannot produce gasoline without producing mazut. To reduce fuel oil output, refineries must proportionally cut total crude processing. This is happening during a seasonal peak in gasoline demand, which will inevitably lead to shortages at gas stations and a sharp spike in domestic prices.
The “Mazut Clot”: Unlike diesel or gasoline, which can be temporarily diverted to the domestic market, Russia does not need fuel oil in such quantities. Rerouting it to southern ports is impossible due to the logistical overload of the railways (RZD is already operating at its limit). The Baltic was the only effective sales channel for “heavy” fractions for refineries in central Russia.
Technological Dead End: Repairing damaged overpasses and terminals in Ust-Luga under the constant threat of new UAV strikes is becoming a Sisyphus task. If the ports do not return to full capacity within a week, the country’s largest refineries will begin to “douse” their furnaces. This isn’t just a loss of export revenue; it’s a direct hit to mobility within Russia — from the spring sowing season to military logistics.
