JapanA tag next to a value names the register that supplied it (hover or tap it for the record and date). Values without a tag come from the ship's own AIS broadcasts or from Wikidata. Position and identity are derived live from AIS.
Ownership & management
Each line shows where the fact comes from. Links backed by an identifier point to the company page.
No owner, operator or manager is recorded for this vessel yet.
Timeline
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 |
|---|---|---|---|
| Niihama JPIHA | Oct 4, 2026, 04:17 UTC | Oct 4, 2026, 12:01 UTC | 7 h 44 min |
| Niihama JPIHA | Oct 1, 2026, 03:15 UTC | Oct 1, 2026, 20:45 UTC | 17 h 30 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, 04:19 UTC | Draught change Reported draught went from 5.2 m to 4 m after leaving Niihama. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | Medium (55%) |
| Oct 1, 2026, 16:29 UTC | Draught change Reported draught went from 4 m to 5.2 m while in port at Niihama. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | Medium (65%) |
