DescriptionSince August 2023, the tanker has been involved in the export of russian oil from russian ports in the Baltic, Black Seas, and the Pacific region, mainly to India, China, and Turkey. The last change of ownership of the vessel took place in July 2023, which indicates that the tanker was purchased, in particular, for the purpose of transporting russian oil. The international non-governmental organization Greenpeace refers to the tanker as a shadowy fleet of tankers that transport russian oil around the world and threaten the environment. Under the sanctions, russia has begun to build up its own shadow fleet of outdated tankers, which has no 'ties' with the G7 and the EU and can transport oil in violation of price caps. russia disguises its shadow activities at sea under the 'convenient' flags of third countries, operates at sea without proper insurance from the international club of insurers, uses complex schemes to conceal the owners of the shadow fleet, uses various deceptive tactics to conceal the origin of its cargo, creates threats to environmental safety with large-scale economic costs for coastal countries due to the growing threat of oil spills, does not use pilots to navigate difficult areas, etc. russia's 'shadow fleet' continues to provide multibillion-dollar revenues for the kremlin bypassing sanctions, disguising its activities under the flags of third countries, using complex schemes to conceal owners, and poses significant environmental threats with significant economic costs to coastal countries and/or the international community due to the outdated and inadequate insurance of shadow fleet tankers. On November 25, 2024, United Kingdom imposed sanctions on a tanker in connection with the transportation of russian oil/oil products from the russian federation to a third country as part of the restrictions on the russian shadow fleet. On January 10, 2025, USA imposed sanctions on the vessel. On February 21, 2025, Canada imposed sanctions on the vessel. On May 20, 2025, the EU imposed sanctions, which enter into force on May 21, 2025, on the tanker for the transportation of crude oil/petroleum products originating in or exported from russia, using irregular high-risk shipping practices as specified in the International Maritime Organization General Assembly Resolution A.1192(33). On June 03, 2025, the sanctions imposed by Switzerland on the vessel came into force. In August 2025, Ukraine imposed sanctions on the tanker's master. Since December 13, 2025, Ukraine has imposed sanctions on the vessel.[sources]
