Timeline

Dated events for this ship from every source Seadar holds, newest first. Each line names its source; derived items say how they were derived.

Date	Event	Source

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 Seadar 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
Aomi JPOMA	Sep 28, 2026, 22:14 UTC	Sep 29, 2026, 06:29 UTC	8 h 15 min

Detected by Seadar 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 Seadar-derived

Patterns Seadar 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.
