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more than 100 million tons (approximately 17% of the world`s oil tanker fleet) consists of more than a thousand mostly outdated, poorly maintained vessels without proper insurance, with ‘confusing’ ownership and management structures located in ‘friendly’ jurisdictions, under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.

During the period of the G7 and EU oil embargo and the price cap policy on russian crude oil/petroleum products, the tanker is involved in the export of russian crude oil/petroleum products mainly from the russian ports of Novorossiysk and Tuapse, Taman crude oil/petroleum products transshipment complex in the Black Sea, as well as through STS transfers with russian affiliation in the Kerch Strait area, near Romania with vessels IMO 9278959, IMO 9288992, IMO 9612909, IMO 6514376, IMO 8727953, IMO 9230505, IMO 9683726. Transshipment of crude oil/petroleum products of russian origin at sea using the STS method allows concealing the ownership and origin of the cargo, and legalizing their supply to the EU, USA and other countries. In turn, the sale of crude oil/petroleum products on the world market allows accumulating significant financial resources in the state budget of the russian federation, which are used, among other things, to build up the military potential of the aggressor state and to provide material support for russia's military operations on the territory of Ukraine.
In July 2023, the tanker was involved in the export of gasoil (almost 30 thousand tons) from the russian port of Tuapse, the sender of the cargo was Amur Trading FZCO, the recipient was Tejarinaft FZCO. There is a production complex in Tuapse belonging to the sanctioned Rosneft - the Tuapse Refinery with a marine terminal.
According to the United Against Nuclear Iran, the tanker has been part of the armada of ghosts helping Iran transport Iranian oil since April 2024.

The tanker during the period of the G7+ oil embargo and the price cap policy on russian crude oil/oil products is involved in the export of russian oil products from russian ports in the Baltic and Black Seas, and resorts to conducting dark activities with the AIS disabled.
The tanker is linked to sanctioned companies Fractal Marine DMCC (UAE), Wanta Shipping LLC-FZ (UAE), etc., which managed the vessel in 2022-2024.
Fractal Marine DMCC (UAE) is considered one of the leading operators of the shadow fleet, which in early 2023 was among the three largest carriers of Russian oil, along with Radiating World Shipping Services LLC (UAE) and Gatik Ship Management (India), and played a significant role in the export of russian oil to countries around the world during the period of sanctions restrictions. Fractal Marine DMCC managed a fleet of 28 tankers as an intermediary between shipowners and charterers.
Fractal Marine DMCC (UAE) and Wanta Shipping LLC-FZ (UAE) are part of a shipping empire controlled by Mohammad Hossein Shamkhani, son of Ali Shamkhani, the chief political advisor to Iran's supreme leader. Mohammad Hossein Shamkhani uses his father's political influence to corrupt top-level officials in the Iranian regime in order to build and operate a huge fleet of tankers and container ships. This fleet transports oil and petroleum products from Iran and Russia, as well as other cargoes, to buyers around the world, generating tens of billions of dollars in profits.
Mohammad Hossein Shamkhani's shipping empire consists of a vast fleet of vessels, ship management companies, and front companies that launder billions of dollars in profits from the global sale of Iranian and Russian crude oil and petroleum products, mostly to buyers in China. The shipping empire takes significant measures to conceal its operations and obscure its ties to the Shamkhani family, Iran, and Russia.
Fractal Marine DMCC has played an important role in the management and operation of the tanker and container ship fleet of Mohammad Hossein Shamkhani's shipping network. Wanta Shipping LLC-FZ (UAE) performs the operational functions of Mohammad Hossein Shamkhani's shipping network fleet.
On February 12, 2026, Ukraine imposed sanctions on the vessel.
On April 15, 2026, the United States imposed sanctions on a tanker as part of restrictions targeting the fleet of Mohammed Hossein Shamkhani’s shipping empire, which is involved in the transport of russian crude oil and petroleum products.
