The vessel is involved in the transportation of russian crude oil during the period of the G7 and EU oil embargo and price-cap policy on russian oil to third countries.
The vessel, through its related companies, including Stream Ship Management FZCO, is affiliated with the sanctioned PJSC Sovcomflot, the largest state-owned shipping company in russia for the maintenance and provision of marine hydrocarbon extraction, transportation of russian oil, petroleum products, and liquefied gas. The main charterers of Sovcomflot vessels are the largest oil and gas companies and traders of russia. Sovcomflot participates in the maintenance of large oil and gas projects in russia: Sakhalin-1, Sakhalin-2, Varandey, Pryrazlomnoye, Novyy Port, Yamal LNG, others. Before the full-scale russian invasion of Ukraine, the company's fleet consisted of about 145 vessels. After the application of sanctions, PJSC Sovcomflot transferred dozens of vessels to the ownership of companies it created, including those in foreign jurisdictions, in order to circumvent them, starting the practice of constant 'juggling' (transferring) vessels to related companies. The tankers 'transferred' by PJSC Sovcomflot to related companies are, according to experts, part of the so-called 'shadow tanker fleet' of the russian federation to continue sales of russian oil, petroleum products, and liquefied gas under Western sanctions.
