I track sanctioned ships on AIS — name changes, MMSI switches, where the lists disagree. Building hullcipher.com.
Three sanctioned tankers, real tracks 100 km apart, one point they all keep snapping to: Fokino, Ussuri Bay, 12 Sep. Mirabel (IMO 9511521), He Bo (9408554, on air as Xing Yuan), Vostochny Prospect (9866392). A minute or two on the spot, then back on track. Interference, not a ship lying.

The tanker in gCaptain's Arctic STS story last week, MIRABEL (IMO 9511521), switched her AIS back on Friday south of Nakhodka. For about six hours her reported position kept snapping to one spot in Ussuri Bay, 60 km from where she actually was, while she steamed east at 10 knots.

Has anyone else noticed the gemstones? Over the last month about thirty sanctioned tankers came up on new Russian MMSIs, and half of them were renamed after minerals. Izumrud, Sapfir, Tanzanit, Morganit, Khrizolit, Giatsint, Turmalin, Nefrit. July's batch was rivers. #ShadowFleet #OSINT

Seven authorities have sanctioned IMO 9418494. Six of them publish no MMSI. Their vessel records don't have a field for it. OFAC publishes one, 352002209 — her old Panama number. We've only ever heard her on 461000231, under Oman. hullcipher.com/vessel/9418494
