The United States has seized a Russian-flagged oil tanker linked to Venezuelan crude exports after a dramatic, weeks-long pursuit across the Atlantic. US forces intercepted the vessel, now known as Marinera (formerly Bella-1), in the North Atlantic on Wednesday following a pursuit that began after the tanker slipped through a US maritime “blockade” near Venezuela. The operation, carried out under a warrant issued by a US federal court, involved the US Coast Guard, US European Command, the Department of Homeland Security, and other federal agencies. Authorities said the seizure was executed for violations of US sanctions targeting oil shipments tied to Venezuela and other sanctioned regimes.
Geopolitical Flashpoint With Russia
The operation appeared to be the first known US military seizure of a Russian-flagged commercial vessel in recent history, prompting sharp diplomatic reactions. Moscow had earlier deployed naval assets, including a submarine, and reportedly showed concern over the pursuit, arguing the ship was in international waters and operating under the Russian flag in compliance with maritime law. Russia’s Foreign Ministry condemned heightened US attention as disproportionate.
US officials maintain that the vessel’s registration switch from other flags to the Russian registry, along with its history of transporting Venezuelan oil in defiance of sanctions, does not shield it from enforcement actions. The Marinera had previously repelled a US Coast Guard boarding attempt near Venezuela in December before heading northward across the Atlantic.
Russia Slams US Over Tanker Seizure
Russia condemned the US for seizing a Russian-flagged oil tanker in the North Atlantic, calling it a violation of international law and freedom of navigation. The Russian transport ministry cited the 1982 UN Convention on the Law of the Sea, saying no state can use force against ships registered under another nation. The tanker, formerly Bella-1 and later Marinera, was sailing under Russian permission since December 24. Contact was lost after US naval forces boarded it in international waters
Implications For Global Energy Markets
The seizure comes amid an intensified US crackdown on “shadow fleet” vessels that evade sanctions to transport Venezuelan and other sanctioned crude oil. Earlier this week, the US also seized another Venezuela-linked tanker in the Caribbean.
Energy markets reacted cautiously, with analysts warning that continued enforcement could tighten supply dynamics for certain crude grades, particularly Venezuelan and Russian barrels already under tight restrictions. The action also highlights Washington’s broader strategy of limiting sanctioned oil flows and redirecting global trade patterns as geopolitical tensions with Russia and OPEC producers linger.
