The tanker has been implicated in the export of russian crude oil / petroleum products from russian ports during the period of the G7 and EU oil embargo and the price cap policy on russian crude oil / petroleum products, in particular in 2023 and 2025.
In June 2023, the tanker was implicated in the export of a gasoil consignment from the russian port of Tuapse, with Amur Trading FZCO as the consignor and Tejarinaft FZCO as the consignee. Tuapse hosts a production complex belonging to the sanctioned PJSC NK Rosneft (ПАО "НК "Роснефть"), namely the Tuapse Refinery with a marine terminal.
In 2025, the vessel again engaged in the export of russian crude oil / petroleum products, in particular from the Sheskharis terminal, which is a transshipment complex and the end point of the main pipelines of JSC Chernomortransneft (АО "Черномортранснефть", TIN 2315072242, under U.S. sanctions), a subsidiary of the sanctioned PJSC Transneft (ПАО "Транснефть", TIN 7706061801). In particular, on January 30, 2025, the tanker IMO 9167150 began conducting dark activities (deliberate disabling of the Automatic Identification System – AIS) in the Exclusive Economic Zone (EEZ) of Ukraine, reappearing 16 days later in the EEZ of Turkey, indicating the route Port Kavkaz (russia) – port Kalamata (Greece). On February 17, 2025, the route was changed from the port of Kalamata to the port of Pylos. On February 18, 2025, the vessel began drifting in Greek waters near Pylos. On February 20, 2025, the tanker carried out a ship-to-ship (STS) transfer with the VLCC-class tanker IMO 9402732, affiliated with the Indian company Gatik Ship Management, one of the leading operators of the so-called "shadow fleet" implicated in the transportation of russian crude oil/ petroleum products in 2022–2023 under Western sanctions.
In September 2025, the vessel was involved in the export of three shipments (totaling nearly 90,000 tons) of russian petroleum products from the russian port of Novorossiysk, in particular the Sheskharis terminal.
In February and March 2026, the tanker exported a total of 90,000 metric tons of petroleum products from the port of Novorossiysk.
Since 2021, the tanker has been operated by Adriatic Tankers Shipping Co., a company incorporated in Panama and headquartered in Greece. The founder of Adriatic Tankers Shipping Co. is Panagis Zissimatos.
The vessel is involved in the oil sector of the russian federation’s economy, the profits from which are one of the most important sources of revenue for the aggressor state’s budget.
