Arrest made after seizure of Russian shadow fleet oil tanker

At least six sanctioned Russian ships aborted attempts to pass through the English Channel in the hours after the UK’s dramatic seizure of one of the Kremlin’s shadow tankers.

In less than 80 minutes, six oil tankers understood to be operating on behalf of Moscow had peeled away from their intended course around the southern edge of England, according to analysis by The i Paper .

Three vessels performed sharp U-turns back in the direction of Scandinavia and Russia, while the others adjusted their courses west to veer towards Ireland, rather than continuing north-east in the direction of the English Channel.

The frantic scramble of the six ships – the Lion I, Sona, Qasr, Pate, Maini and C-Viking – began at around 8:48am on Sunday and lasted for about 77 minutes. All the vessels feature on the UK Sanctions List for reasons including helping to “destabilise Ukraine” or because they “benefit the government of Russia”, however they travel under other flags including Sierra Leone and Cameroon.

Some eight hours before, British forces boarded a sanctioned Russian oil tanker in the English Channel. The detention of the Smyrtos , carrying some 700,000 barrels of Russian crude oil worth an estimated £45m, is the first time Britain has led an interception of a so-called shadow fleet vessel.

In March, Sir Keir Starmer announced that British armed forces had been given permission to board sanctioned vessels passing through UK waters after receiving updated legal advice. But the move, which would have seen Britain follow countries such as France, Sweden and Finland in seizing the tankers, was followed by an uncomfortable hiatus.

This paper previously revealed that at least 205 sanctioned tankers had sailed through UK waters between Starmer’s announcement on 25 March and the end of last month.

The term “shadow fleet” applies to the more than 700 vessels being used by Moscow to get around western measures designed to hobble its fossil fuel exports. The system uses ships owned through hazy offshore structures, often sailing under the protection of obscure flag states and eschewing Western maritime services such as insurance.

Many of the vessels are consequently beyond what would be considered the maximum serviceable age by Western oil companies, raising fears over maintenance and the potential for an environmental catastrophe should an accident ever happen in the Channel, the world’s busiest shipping lane. At an inspection last year, the Smyrtos was found to have 18 deficiencies, including fire safety risks and engine problems.

The six-hour, pre-dawn operation

Downing Street said the six-hour, pre-dawn British operation, which involved Royal Marine commandos and specialist National Crime Agency officers boarding the Smyrtos from helicopters, had been designed to disrupt Russia’s vastly lucrative oil trade. Since its invasion of Ukraine in February 2022, Moscow is estimated to have made at least £654bn in revenues from oil sales, of which about 75 per cent has been facilitated by shadow fleet tankers.

Starmer, who has been under pressure to display Britain’s military resolve following the resignation of John Healey as defence secretary over the delayed blueprint for overhauling UK forces, said: “This successful operation delivers yet another blow to Russia and reminds those fuelling Putin’s war in Ukraine that we will not let them hide.”

Britain’s coastal waters, and in particular the English Channel, represent a vital conduit for the Kremlin’s ability to mobilise Russia’s huge fossil fuel reserves to fund the Ukraine war. A steady stream of tankers ploughs a route from Russia’s two main oil terminals on the Baltic Sea, Primorsk and Ust-Luga, and passes by the British coast en route to destinations including India and China.

Many vessels, including the Smyrtos, also conduct so-called STS or ship-to-ship transfers whereby two vessels meet in open seas to pump oil from one vessel to the other as part of a strategy to obscure the origin of cargoes.

Not all suspected shadow fleet vessels active around the UK appeared to have abandoned their routes, according to this paper’s analysis of data from MarineTraffic, a maritime intelligence and vessel-tracking platform.

At least two sanctioned craft, the Solaris and Norelia , snuck through the Channel in the early hours of this morning after already entering the busy shipping lane. On Sunday afternoon, the Norelia , which is listed as being en route to Port Said in Egypt from the Russian port of Primorsk, was about to pass beyond the coast of Cornwall and head down around th…
