DescriptionDuring 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 russian ports in the Black Sea, including through STS transfers with russian affiliation. Transshipment of crude oil/petroleum products of russian origin by STS method at sea allows concealing the ownership and origin of the cargo, legalizing their supply to the EU, the US 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 calls at the ports of the TOT of Crimea of Ukraine, in particular, in January and April 2025, the vessel called at the port of Komysh-Burun, in April 2025, after calling at the port in the TOT of Crimea of Ukraine, the tanker called at a Turkish port. The tanker is engaged in dark activities in the Kerch Strait area, near russian ports in the Black Sea, calling, in particular, at the Sheskharis terminal (Novorossiysk), which is a transshipment complex, the end point of the main pipelines of Chernomortransneft JSC (TIN: 2315072242, under USA sanctions), a subsidiary of the sanctioned russian Transneft PJSC (TIN: 7706061801). In September 2023, the tanker was involved in the export of a batch of gas oil (more than 30 thousand tons) from the russian port of Tuapse by order of Tüpras Türkiye Petrol Rafinerileri A.Ş., Tejarinaft FZCO), the sender of the cargo was the sanctioned russian PJSC Rosneft Oil Company. There is a production complex in Tuapse belonging to the sanctioned Rosneft - the Tuapse Refinery with a marine terminal. The crew of the tanker is recruited from the russian federation. According to United Against Nuclear Iran, the tanker has been part of the armada of ghosts that have been helping Iran transport Iranian oil since October 2024. The tanker is affiliated with the sanctioned company Eco Max FZE (UAE), which manages tankers associated with the illegal supply of Iranian oil. In October 2024, the United States imposed sanctions on the tanker as a property in which the sanctioned company Eco Max FZE has an interest. Since October 24, 2025, the EU has imposed sanctions on the vessel.[sources]
