On the 13th of August 2026, SynMax's maritime domain awareness platform, Theia, detected the sanctioned tanker ZALIV VOSTOK (IMO 9360130) alongside the FSU UMBA, a sanctioned floating storage unit used for the storage and transfer of Russian crude oil, at anchor in Kola Bay, Russia. The two vessels were assessed to be conducting a ship-to-ship (STS) transfer.
The following day, the ZALIV VOSTOK was imaged departing Kola Bay. Approximately four weeks later, on the 11th of September, Theia identified her again, this time in the Sea of Japan south of Nakhodka, Russia, alongside the sanctioned Sierra Leone-flagged tanker CECILA (IMO 9247792). Again, the behavior of the two vessels was consistent with a STS transfer. AIS data was not received from either vessel during the operation. Following the interaction, the CECILA made for Qingdao Port, China, where she was imaged alongside on the 18th of September.
Theia was able to track the ZALIV VOSTOK and the CECILA by automatically fusing more than 40 million km² of daily satellite imagery with AIS and SAR data, among others, rather than relying on any single source. SynMax's Agentic AI platform, Atlas, allows analysts to surface suspicious behavior globally, alerting analysts to vessels of interest in near real time and carrying the analysis forward when the transponders go quiet.
