Sweden Detains Captain of Russian Tanker in Shadow Fleet Operation

A Russian captain has been detained by Sweden following the boarding of a vessel suspected of being part of a network evading sanctions. The ship, Sea Owl One, was seized in Swedish waters amidst allegations of operating under a false flag.

Swedish authorities captured the captain of the Sea Owl One, a tanker associated with Russia's shadow fleet, while it sailed under what is suspected to be a false Comoran flag. The vessel is under scrutiny for evading Western sanctions on Russian oil exports. This incident marks Sweden's second seizure of a suspected shadow fleet vessel this week, underscoring ongoing efforts to curb sanctioned operations.

A Swedish court has ordered the detention of a Russian captain from a ship believed to be operating under false pretenses within Moscow's shadow fleet.

The man, whose name hasn't been disclosed, appeared in court in Ystad after his arrest by the Swedish Prosecution Authority on accusations of using forged documents.

Members of the Swedish Coast Guard boarded the Sea Owl One, a 228-meter tanker, while it was navigating Swedish waters under a Comoran flag that they suspect to be bogus. This vessel is included on a list of EU-sanctioned ships.

Moscow has relied on a network of vessels with obscure ownership to circumvent Western sanctions on its oil exports.

The Sea Owl One was en route from Santos, Brazil to Primorsk, Russia when intercepted by authorities; it has a history of transporting oil between Russia and Brazil, according to the Swedish Coast Guard.

The Prosecution Authority confirmed the captain's detention but did not provide specific details on the duration, although it typically lasts for 14 days. Prosecutors plan further questioning of the captain.

The Coast Guard intervened after raising suspicions about the ship’s registration under Comoros, which is believed to breach international law. Officers’ concerns intensified when the captain presented seemingly counterfeit documents.

The Russian embassy confirmed that 10 of the 24 crew members aboard the Sea Owl One, including the captain, are Russian, while others hail from Indonesia. They are closely monitoring the developments.

This latest incident marks the second vessel seizure by Swedish authorities in a week suspected of being part of Russia's shadow fleet. On March 6, the Coast Guard seized the Caffa, a Guinean-flagged cargo ship, on similar allegations of carrying stolen Ukrainian grain.

Additionally, France has also intercepted several tankers associated with Russia's shadow fleet in prior months.

Western sanctions targeting Russian oil exports have intensified since the full-scale invasion of Ukraine in 2022, aimed at cutting off financial resources for the ongoing conflict.

Besides evading sanctions, Moscow's shadow fleet has been implicated in misrepresenting their location data, sabotaging undersea cables, and deploying drones.
