SAPPHIRE

The tanker is involved in the export of sanctioned russian oil products from russian ports, mainly in the Black Sea, to Turkey and other third countries using deceptive, high-risk practices (disabling AIS).
The vessel, through related companies, including the sanctioned Stream Ship Management FZCO, Sun Ship Management, Oil Tankers SCF MGMT FZCO, affiliated with the sanctioned PJSC Sovcomflot, the largest state-owned shipping company in russia that services and supports offshore hydrocarbon production, transportation of russian crude oil, oil products, and liquefied natural gas. The major charterers of PJSC Sovcomflot's vessels are russia's largest oil and gas companies and traders. PJSC Sovcomflot is involved in servicing major oil and gas projects in russia: Sakhalin-1, Sakhalin-2, Varandey, Prirazlomnoye, Novy Port, Yamal LNG and others. After the sanctions were imposed, PJSC Sovcomflot transferred dozens of vessels to the ownership of companies it had set up, including in foreign jurisdictions, and began the practice of constantly 'juggling' (transferring) vessels to related companies. According to expert estimates, the tankers 're-registered' by PJSC Sovcomflot to related companies are part of the so-called 'shadow tanker fleet' of the russian federation to continue selling russian crude oil, oil products, and liquefied natural gas under Western sanctions.
