Cyberboroshno's analysis of satellite imagery tracked the shadow fleet's collapse in numbers. Around 1 July, about 100 vessels sat north of the Crimean Bridge in the Azov Sea, with roughly 100 more to the south near the Taman port. By 6 July, the northern group had thinned to about 40. By 8 July, some 20 remained in the north, one of them burning, with massed movement toward the bridge.
The northern vessels are mostly small river-class tankers, the analysts found. They shuttle fuel south, where cargo is transshipped onto much larger ships for direct Black Sea runs to importer countries. The vessels belong to Russia's so-called shadow fleet, used to circumvent sanctions.
I hadn't seen this detail elsewhere, but it seems like disabling these smaller tankers would have a wider effect on Russia's oil exports than just taking down ocean-going tankers. They hit a bunch of oil depots in that supply the tankers, too.
I think I've seen videos of this guy in his car looking for/complaining about gasoline. I guess he wasn't successful since he's walking around now.
