Dated events for this ship from every source Voydar holds, newest first. Each line names its source; derived items say how they were derived.
Owner, operator and manager changes found by comparing yearly EU MRV reports are dated to the reporting year ("during 2025"), not to a day. Port calls here are the most recent only; the full lists are further down.

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 |
|---|---|---|---|
| Belfast GBBEL | Oct 1, 2026, 14:29 UTC | Oct 2, 2026, 23:21 UTC | 32 h 52 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 2, 2026, 14:17 UTC | Draught change Reported draught went from 8.5 m to 6.4 m while in port at Belfast. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | High (75%) |

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.
