German-French Resolution Calls for Tougher Measures Against Russia’s Shadow Fleet
German and French lawmakers have drafted a joint resolution calling for more concrete measures against Russia‘s “shadow fleet.” The document is expected to be adopted on June 22 during a session of the Franco-German Parliamentary Assembly (DFPV). According to German and French legislators, stronger monitoring mechanisms and the detention of vessels found to be violating existing laws are necessary. The draft also calls for intensified diplomatic efforts targeting countries whose flags are used by vessels associated with the Russian shadow fleet.
The document emphasizes that Russia‘s shadow fleet represents not only a geopolitical challenge but also a significant security and environmental threat. Many of the tankers involved are aging, poorly maintained, and fail to meet international safety standards. In addition, some vessels are suspected of being used for sabotage and intelligence-gathering activities.
The Shadow Fleet: A Vast Network of Aging Tankers
Russia‘s shadow fleet is a vast network of aging tankers established by the Kremlin to circumvent Western sanctions and facilitate illicit oil exports. According to expert estimates, the fleet consists of approximately 1,500 vessels, representing nearly 17 percent of the global tanker fleet. Most of these ships are between 15 and 25 years old, operate through opaque ownership structures, and sail under flags of convenience. To conceal the origin of their cargo, vessel operators routinely disable automatic identification systems (AIS) and conduct ship-to-ship oil transfers in international waters.
International Pressure Intensifies
As part of sanctions packages targeting Russia—including the 20th EU sanctions package adopted in April 2026 and additional restrictions introduced in June—the European Union imposed sanctions on hundreds of tankers linked to the shadow fleet. International pressure on the fleet has intensified significantly in recent months, with European states increasingly detaining vessels for fraudulent registration, forged documentation, or unlawful use of national flags.
On June 14, British Royal Marines and officers from the United Kingdom’s National Crime Agency boarded the tanker MV Smyrtos. According to British officials, the vessel had entered UK territorial waters without a valid national flag.
A Broader European Security Challenge
The initiative by German and French lawmakers demonstrates that the issue of Russia‘s shadow fleet has moved beyond the realm of sanctions enforcement and is increasingly being viewed as a broader European security challenge. Paris and Berlin are effectively signaling their readiness to shift from passive monitoring toward more robust mechanisms for vessel inspection, detention, and enforcement.
The continued operation of Russia‘s shadow fleet enables the Kremlin to maintain substantial revenues from oil exports and sustain financing for its war against Ukraine despite international restrictions. Every successful voyage by a shadow-fleet tanker not only undermines the effectiveness of sanctions but also contributes indirectly to the continuation of Russia’s military aggression against Ukraine, with direct implications for European security.
A New Maritime Containment Strategy
Developments over the past year indicate that several European countries—including France, Sweden, and the United Kingdom—are gradually abandoning the de facto immunity previously enjoyed by vessels associated with the Russian shadow fleet. The detention of tankers for forged documentation or unlawful flag use is creating legal and operational precedents that could form the foundation of a new maritime containment strategy aimed at increasing the costs of sanctions evasion for Moscow.
For Europe, the Russian shadow fleet represents a dual challenge, as commercial shipping activities are increasingly being used as cover for hybrid operations targeting EU member states. Certain vessels may be employed for intelligence collection, surveillance of critical infrastructure, or sabotage activities, transforming civilian shipping into another instrument of Russian pressure against European countries.
