The European Union is preparing new Strict measures against the so-called “shadow fleet” of vessels transporting oil in breach of international requirements, EU foreign policy chief Kaja Kallas said after a meeting of the EU Foreign Affairs Council in Brussels.
According to Kallas, existing restrictions have already had a significant impact on such carriers. More than 550 vessels have been added to the sanctions list, and data from European intelligence services indicate a further decline in seaborne oil exports. EU officials note that even the first weeks of the restrictions led to a noticeable drop in revenues from export routes through the Baltic and Black Seas.

The bloc is now discussing a mechanism for preliminary agreements with flag states that would allow inspections of their vessels. This arrangement, Kallas said, is intended to make oversight of oil shipments more predictable and more firmly grounded in legal procedures.
Ministers also backed a shift to “rolling” updates of the sanctions list, under which new vessels and related companies would be added as violations are identified, without waiting for another large sanctions package. In parallel, the EU is holding consultations with partners, including the United States and the United Kingdom, to align measures and increase their overall impact.
According to the European side, a range of instruments is under consideration, from environmental requirements to insurance and registration procedures that could slow the operations of vessels operating outside international norms.
It is noteworthy that Ever since the U.S. introduced sanctions on Russian energy, Moscow has been transporting oil under the radar using clandestine techniques such as shadow fleets. Demand for Russian crude has risen from some countries as Putin has offered oil at highly discounted rates to maintain Russia’s export revenues. Countries such as China and India, who have so far ignored the U.S. sanctions, have been driving this demand. Now, there’s a plan to crack down on Russian shadow fleets to ensure that they cannot circumvent sanctions so easily.

Shadow fleets have long been used to export crude to other parts of the world. Both Iran and Venezuela have been known to use the technique to avoid sanctions, with many of their oil products bound for China and other parts of Asia that do not adhere to U.S. sanctions.
Russia began to use shadow fleets to move its energy products following its 2022 invasion of Ukraine and the subsequent sanctions it faced. To ensure its economy was not severely disrupted, Putin opted to clandestinely continue to export crude to bring in revenue. To achieve this, Russia has been using a fleet of around 700 older, poorly maintained ships without modern identification systems to transport oil while avoiding detection.
The term shadow fleet has a wide range of definitions, but when it comes to Russia’s use of this method it is generally taken to mean “all vessels lacking Western insurance and belonging to non-EU/G7+ companies”. Russia’s shadow fleet “makes use of flags of convenience and intricate ownership and management structures while employing a variety of tactics to conceal the origins of its cargo, including ship-to-ship transfers; automatic identification system blackouts; falsified positions; transmission of false data; and other deceptive or even illegal techniques.”
