KOYSUG

The vessel has been implicated in the supply of jet fuel and other strategic cargoes to the Middle East for the russian armed forces’ contingent in Syria, acting in the interests of the Ministry of Defence of the russian federation (Министерство обороны российской федерации). It has made port calls at terminals in the temporarily occupied territory (TOT) of Ukraine, including the port of Crimea.
In 2024, the tankers Azov (IMO 8943260), Koysug (IMO 8883252), and Nizami Ganjavi (IMO 9369617) were added to the list of vessels used by the russian federation for covert deliveries to Syria in the interests of the Ministry of Defence. Throughout 2024, these vessels were repeatedly deployed for voyages from Black Sea ports of the russian federation to Syria, following the established concealment pattern of disabling Automatic Identification System (AIS) transponders in the Mediterranean Sea, either north or south of Cyprus, to obscure port entries and departures in Syria.
Aviation fuel and diesel were shipped from russian ports, including the port of Azov, while petrol was supplied from Iran. These measures were adopted by the russian federation following successful 2023 Ukrainian Defence Forces strikes on the russian tanker Sig in the Black Sea, which had been engaged in transporting jet fuel to Syria for the russian military contingent.
