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 Rotterdam around Oct 10, 2026, 16:40 UTC, most likely between Oct 5, 2026, 18:03 UTC and Oct 21, 2026, 15:08 UTC. Based on 47 past transits between NLBOT and Rotterdam seen in our port calls. The crew-reported ETA is Sep 29, 2026, 01:30 UTC.
