The shadow tanker fleet transports growing volumes of sanctioned oil around the world, generates billions of dollars in revenue for russia and Iran, threatens environmental safety in the oceans, serves as a spy platform, and is used for sabotage activities in the interests of the aggressor.
The sanctioned countries are looking for new markets for oil, building up their tanker fleet to circumvent restrictions, and shipping crude oil mainly to China and India.
The shadow tanker fleet with a total deadweight of more than 100 million tons (approximately 17% of the world`s oil tanker fleet) consists of more than a thousand mostly outdated, poorly maintained vessels without proper insurance, with ‘confusing’ ownership and management structures located in ‘friendly’ jurisdictions, under ‘convenient’ flags. Such vessels resort to deceptive tactics at sea to conceal the origin of their cargo, threaten ‘environmental chaos’ and billions of dollars in losses to coastal countries by passing through busy, narrow international transportation routes without pilotage. Since the beginning of russia`s full-scale invasion of Ukraine, shadow tankers have already been involved in more than 50 incidents from the Danish Straits to Malaysia.

The VLCC tanker is involved in the transportation of Iranian oil, as well as in the export of russian oil/petroleum products during the G7+ oil embargo and price cap policy on russian crude oil/petroleum products.
On 13 March 2025, the United States imposed sanctions on Turquoise Sea Marine Limited (Seychelles), the owner of the tanker, for its activities in the petroleum sector of the Iranian economy. On the same date, the United States imposed sanctions on the tanker as property in which Turquoise Sea Marine Limited has an interest.
Since December 25, 2025, the owner and manager of the large-tonnage tanker has been the russian company Burevestmarin LLC, established in July 2025. The director and sole owner of the company is Ilya Bugay, an entrepreneur from the temporarily occupied territory of Crimea, Ukraine. The company also became the owner of two other tankers:
MARINERA IMO 9230880 (under US sanctions), detained on January 7, 2026, by the US Coast Guard in the North Atlantic south of Iceland. The vessel was detained after a two-week pursuit in the Atlantic after it evaded inspection in the Caribbean Sea. As of January 15, 2026, the tanker is under US control and has been delivered to Moray Firth (Scotland, UK);
GALLILEO IMO 9256860 (under US sanctions), detained on January 15, 2026, in the Caribbean Sea as part of Operation Southern Spear by marines and sailors from the aircraft carrier USS Gerald R. Ford on charges of violating the US naval blockade and sanctions against Venezuela, as well as transporting Venezuelan oil.
As of January 15, 2026, the tanker IMO 9153525 last transmitted its coordinates on January 1, 2026, while anchored in the Caribbean Sea off the coast of Aruba.
