DescriptionDuring the period of the G7 and EU oil embargo and the price-cap policy on russian crude oil, the tanker is involved in the export of russian oil from russian ports in the Pacific region, in the Black Sea, mainly to China and Turkey. According to the data of United Against Nuclear Iran (UANI), which monitors Iranian-related tanker traffic using satellite data, the vessel was involved in the transportation of Iranian oil and switched to transporting russian oil. Since the beginning of russia's full-scale invasion of Ukraine in February 2022, more than 100 vessels that previously helped Tehran export Iranian export oil are now helping russia transport russian oil/oil products. The international public organization Greenpeace refers to the tanker as a shadowy fleet of tankers transporting russian oil around the world and threatening the environment. The shadow fleet of russia continues to generate 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threats with significant economic costs to coastal countries and/or the international community due to the outdated and inadequate insurance of shadow fleet tankers.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 May 09, 2025, the United Kingdom imposed sanctions on the tanker as part of the restrictions on the russian shadow fleet. In June 2025, Canada imposed sanctions on the vessel. From July 20, 2025, the EU imposed sanctions on a tanker for transporting crude oil/petroleum products that originate in russia or are exported from russia using irregular and high-risk shipping practices as set out in the International Maritime Organization General Assembly resolution A.1192 (33). On August 12, 2025, Switzerland imposed sanctions on the vessel.[sources]
