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.

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 29, 2026, 22:28 UTC | Draught change Reported draught went from 7 m to 9.7 m while in port at Puerto Alumbrera. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
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.
