Port calls
Two kinds of evidence, kept apart: calls Voydar detected from the ship's AIS positions, and arrivals and departures published by port authorities and customs records.
Detected from AIS AIS-detected
| Port | Arrived | Departed | Time in port |
|---|---|---|---|
| Ronne DKRNN | Oct 1, 2026, 13:00 UTC | Oct 1, 2026, 15:14 UTC | 2 h 14 min |
| Ronne DKRNN | Sep 30, 2026, 03:59 UTC | Sep 30, 2026, 15:18 UTC | 11 h 19 min |
Detected by Voydar when the ship's AIS positions stayed slow inside a harbour area. Calls shorter than 30 minutes are not shown. Depends on AIS reception; detection started on June 8, 2026.
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.
| When | What we observed | Confidence |
|---|---|---|
| Oct 1, 2026, 15:28 UTC | Draught change Reported draught went from 4.8 m to 5.3 m after leaving Ronne. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | Medium (55%) |
Source: AISstream.io global terrestrial AIS. AIS data: AISstream.io. Licence: none published.
Derived from AIS positions of feeds whose terms allow display on Voydar. Coverage is terrestrial: gaps are reported only where our receivers kept hearing other ships. Detections below medium confidence are not shown.
