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more than 100 million tons (approximately 17% of the world`s oil tanker fleet) consists of more than a thousand mostly outdated, poorly maintained vessels without proper insurance, with ‘confusing’ ownership and management structures located in ‘friendly’ jurisdictions, under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+ oil embargo and the price cap policy on russian crude oil/petroleum products, the VLCC tanker is involved in the export of russian crude oil/petroleum products, in particular, through STS transfers near European countries.
In particular, the tanker carried out STS transmissions with the sanctioned tanker IMO 9419448 in July 2024 in the Gulf of Lakonikos (Greece), which left the russian port of Ust-Luga on June 23, 2024. There are also STS transmissions in the Laconikos Gulf (Greece) with the super tanker IMO 9402732, affiliated with the Indian company Gatik Ship Management, one of the leading operators of the so-called "shadow" fleet involved in the transportation of russian crude oil/petroleum products in 2022-2023 under Western sanctions. The super tanker IMO 9402732 carries out STS transmissions with tankers delivering russian crude oil/petroleum products, in particular from russian ports in the Black Sea. Earlier, there were STS transmissions in the Laconikos Gulf with the tanker IMO 9144782 of the shadow fleet built in 1997, which is also involved in the transportation of Iranian oil.
Transshipment of crude oil/petroleum products of russian origin by STS method allows to conceal the ownership and origin of the cargo, legalize their supply to EU countries, 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.
The tanker is also involved in the transportation of Iranian oil and petroleum products.
On May 19, 2026, the United States imposed sanctions on the tanker.
