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

| Jurong SGJUR | Sep 24, 2026, 00:34 UTC | Sep 25, 2026, 05:11 UTC | 28 h 36 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 |
|---|---|---|
| Sep 24, 2026, 13:10 UTC | Draught change Reported draught went from 8.8 m to 8 m while in port at Jurong. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | Medium (65%) |
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.
