A sanctions list's date is the earliest date the list shows the name, not when the ship took it. A name on a list is shown as a former name only where AIS shows the ship using another name after that date; otherwise it is listed as a name the list uses. AIS name changes are dated when Voydar saw them.

Behaviour at sea Voydar-derived
Patterns Voydar derived from this ship's AIS broadcasts. They are inferences, not reports: each one shows how it was computed and how confident we are, and none of them says why a ship behaved this way.
Predicted arrival
Voydar estimates arrival at Brunsbuttel around Oct 5, 2026, 23:38 UTC, most likely between Oct 5, 2026, 23:02 UTC and Oct 6, 2026, 00:38 UTC. Based on 63 past transits between DEHTU and Brunsbuttel seen in our port calls. The crew-reported ETA is Oct 5, 2026, 08:30 UTC.
