DescriptionThe tanker has been implicated in the export of russian crude oil / petroleum products from russian ports to third countries during the G7 and European Union oil embargo and price cap policy on russian crude oil / petroleum products/ The vessel has engaged in deceptive, high-risk practices (disabling the AIS signal, conducting dark activities at sea). In 2024, the tanker transported russian oil from the port of Primorsk to India. The transportation was carried out under the command of Captain Konstantin Kovalenko. The tanker is affiliated with Prominent Shipmanagement LTD, a company established in Hong Kong in 2022, which was sanctioned by the US on January 10, 2025, for its activities in the energy sector of the russian federation. All tankers operated by the Dubai-based company K&O Shipmanagement FZE, affiliated with the sanctioned russian PJSC Sovcomflot, were transferred to the management of Prominent Shipmanagement LTD. The vessels were included in the Indian Register of Shipping (the classification society with the largest market share of the so-called shadow fleet). Sovcomflot PJSC is russia's largest state-owned shipping company providing services and support for offshore hydrocarbon production and the transportation of russian oil, petroleum products, and liquefied gas. The main charterers of Sovcomflot PJSC vessels are russia's largest oil and gas companies and traders. PJSC Sovcomflot participates in the servicing of major oil and gas projects in russia: Sakhalin-1, Sakhalin-2, Varandey, Prirazlomnoye, Novy Port, Yamal LNG, and others. The shadow tanker fleet continues to generate multibillion-dollar revenues for the kremlin by circumventing sanctions by disguising its activities under third-country flags, using complex schemes to conceal owners, and poses significant environmental safety hazards with significant economic costs to coastal countries and/or the international community due to the outdated and inadequately insured shadow fleet tankers. On January 10, 2025, USA imposed sanctions on the vessel. On February 24, 2025, the United Kingdom imposed sanctions on the vessel. On February 24, March 04, 2025 EU and Switzerland respectively imposed sanctions on the tanker for transporting crude oil/oil products originating in or exported from russia using irregular and high-risk shipping practices as specified in the International Maritime Organization General Assembly resolution A.1192 (33) (EU sanctions will enter into force on February 25, 2025). In June 2025, Canada imposed sanctions on the vessel. In June 2025, Australia imposed sanctions on the vessel. In August 2025, Ukraine imposed sanctions on the tanker's master. Since October 30, 2025, New Zealand has imposed sanctions on the tanker.[sources]
