Estonia has decided against detaining vessels associated with Russia’s shadow fleet in the Baltic Sea, citing concerns that such actions could lead to military escalation with Moscow. This statement was made by the Commander of the Estonian Navy, Ivo Värk, and reported by Reuters.
The shadow fleet, which consists of oil tankers circumventing international sanctions imposed on Russia due to its ongoing conflict in Ukraine, has prompted increased efforts from the United Kingdom and several European nations, including France, Belgium, and Sweden, to detain these vessels.
Estonia, the northernmost Baltic state located near key Russian oil and gas export facilities in the Gulf of Finland, is exercising restraint following an unsuccessful attempt to board a Russian ship last year. Värk emphasized, “The risk of military escalation is simply too high.”
In May 2025, Estonia reported that a Russian fighter jet entered NATO airspace over the Baltic Sea during an effort to stop an unflagged oil tanker that was ignoring Western sanctions and heading towards Russia. The aircraft ultimately escorted the tanker back into Russian waters.
Since then, Russia has increased its military presence in the Gulf of Finland, deploying two or three armed naval vessels for continuous patrols. Additionally, more ships have been stationed in other parts of the Baltic Sea along routes used by tankers transporting Russian oil.
Värk noted, “The Russian military presence here in the Gulf of Finland has become much more apparent.” He stated that Estonia would only consider intervention in cases of immediate danger, such as damage to underwater infrastructure or oil spills.
He contrasted this with the situation in the Atlantic and North Seas, where Russian military presence is minimal, allowing for more freedom of action regarding vessels without the same risk of military confrontation.
On April 10, reporters from Reuters observed a Russian Navy corvette near a large group of tankers waiting to enter a nearby Russian port to load oil. Värk indicated that the number of tankers anchored in Estonia’s economic zone at the Vainloo anchorage had tripled to approximately 30-40, following recent Ukrainian drone attacks on Russian ports that disrupted their loading schedules.
The Kremlin views these sanctions as attempts to undermine its economy and asserts that its vessels have the right to free passage in the Baltic Sea, warning of potential responses to any efforts to stop them.
Russia’s Shadow Fleet and International Sanctions
In response to international sanctions, Russia has established a shadow fleet comprising a network of oil tankers designed to bypass these restrictions. This fleet allows the Kremlin to continue exporting oil, particularly to China and India, despite the EU’s import bans on Russian oil.
According to the Main Intelligence Directorate of Ukraine’s Ministry of Defense, Russia’s shadow fleet includes over a thousand tankers, with 238 actively engaged in circumventing sanctions. These vessels often change flags, disable tracking systems, and operate without proper insurance, complicating detection and identification efforts.
The international community has been actively addressing this issue. The European Union has repeatedly expanded its sanctions lists to include vessels linked to the shadow fleet, with the latest sanctions package adding several dozen ships involved in the illegal transport of Russian oil.
Additionally, Australia has implemented sanctions against 60 shadow fleet vessels for the first time, while Canada has announced sanctions against over 200 ships used to evade sanctions. Despite these international efforts, Russia continues to leverage its shadow fleet to sustain its economic interests and fund military operations.
Estonia has opted not to detain Russian shadow fleet vessels in the Baltic Sea, citing military escalation risks. The shadow fleet, which circumvents sanctions, remains a focal point for international scrutiny, with various nations intensifying their efforts to address this issue.
