Swedish authorities have recently increased their scrutiny of suspicious vessels in their territorial waters, with the latest incident involving the boarding of a tanker named 'Sea Owl'. This vessel is suspected of being part of a so-called 'shadow fleet' and is accused of carrying oil or other liquid fuels in violation of EU sanctions. According to the head of the ministry, the tanker does not register under any country's flag, raising suspicions regarding its ownership and cargo.

This event marks the second interception of a suspicious vessel in a week, following the detention of another cargo ship, 'Caffa', which was heading to St. Petersburg. The Swedish Coast Guard has described the 'Sea Owl' as sailing under a 'false' Comoros flag, posing a danger not just to maritime safety but also to the environment. An examination of the vessel's seaworthiness is currently underway, reflecting the serious concerns surrounding the operations of such tanker ships in European waters.

Intelligence gathered by maritime analysis company Starboard Maritime Intelligence adds further credibility to these concerns, indicating that 'Sea Owl' is 228 meters long and lacks confirmation of its registration under Comoros jurisdiction in existing databases. The ship was reportedly en route to Primorsk, Russia, from Santos, Brazil, suggesting a potential link to flag-of-convenience practices often used to bypass legal restrictions. The implications of these findings signal increased vigilance and enforcement efforts from European authorities regarding illegal oil transport amidst ongoing geopolitical tensions.
