Explore how European coastguards are tackling the threat from Russia's covert oil transport network, often evading sanctions through deceptive tactics.

European coastguards are on high alert as they face the rising challenge of Russia's 'shadow fleet'—a network of oil tankers skirting sanctions imposed after the Ukraine invasion. This article dives into the intricacies of maritime enforcement against these vessels, discussing their covert operations and the limitations facing naval authorities. Despite increasing regulations and growing enforcement measures, tracking these ships reveals a complicated web of obscure ownership and flagging practices, complicating efforts to curb Russia's oil exports.

Out on the western Baltic, a coastguard officer radios a nearby, sanctioned oil tanker.

Swedish Coastguard calling… Do you consent to answer a few questions for us? Over.

Through heavy static, barely audible answers crackle over from a crew member, revealing the ship's insurance details and a journey to Russia to collect oil.

This is the front line of Europe's uneasy standoff with Russia's so-called shadow fleet—hundreds of tankers used to evade a price cap on Russian oil exports.

After Russia's invasion of Ukraine, Western countries imposed sanctions on Russian energy, which Moscow is hiding behind this network of aged tankers with obscure ownership.

Recent investigations reveal that some are involved in undersea sabotage and are flagged falsely, raising the alarm for European authorities. The rise in such tankers is notable, with an increase to over 450 ships reported.

In Estonia, military officials report numerous vessels passing through, exposing a significant challenge for maritime security. Commodore Ivo Värk expressed concern over increased sightings and the clear defiance of sanctions.

Through tracking investigations, one tanker named Unity exemplifies the issue: originally flagged and later scrubbed, it continues to operate despite being sanctioned.

These vessels contribute to Russia’s significant oil revenues, but coastal nations face limitations in controlling these operations due to maritime law regarding innocent passage.

As patrols continue, these illicit practices challenge international shipping norms, with the future of maritime enforcement hanging in the balance.

The complexity of intervention in these situations often keeps authorities cautious, balancing enforcement risks against potential escalation.

The situation highlights environmental risks and the deteriorating adherence to global maritime law due to the rise of a fleet ensconced in secrecy, calling into question the integrity of marine governance.
