A Russian tanker transporting millions of dollars’ worth of sanctioned oil is reportedly navigating the English Channel, raising alarms about potential military conflict in NATO waters.
This situation arises as tensions between Russia and NATO escalate, leading the Royal Navy to increase surveillance of vessels that are under sanctions from the U.S. and its allies in this crucial shipping lane.
According to reports, there are claims that around 800 shadow tankers have transited the Bosphorus Strait, further fueling Russian President Vladimir Putin’s military efforts in Ukraine. Multiple oil tankers linked to Russia are currently being monitored—such as the Rigel, Hyperion, and Kousai—all of which are under Western sanctions.
One significant vessel, the Rigel, is a large Suezmax-class tanker that left the Russian port of Primorsk on February 2, carrying close to one million barrels of oil valued at roughly $55 million.
Despite sanctions from the UK, EU, and Canada that restrict the use of port facilities, “innocent passage” remains allowable under maritime law. The Kousai, which hoists a Sierra Leone flag, left Ust-Luga on February 2 but was instructed to provide proof of insurance within a day.
The Hyperion, also facing sanctions from the U.S., recently changed its flag after shipping oil to Venezuela, likely as a way to disguise ownership and evade detection.
Security analysts caution that the risk of geopolitical tensions escalating in the area is increasing. A professor noted that the UK and its allies might soon adopt tougher measures against these Russian vessels, suggesting a military clash at sea in the Channel or North Sea is possible this year.
A spokesperson from the UK Ministry of Defense emphasized that disrupting and discrediting Russia’s shadow fleet remains a high priority for the government. This includes requesting proof of insurance for over 600 suspected vessels since late 2024.
The U.S. has also intensified its efforts, seizing at least seven tankers linked to violating oil sanctions since December 2025, including several in the Caribbean.
