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
Liverpool GBLIV	Oct 1, 2026, 01:24 UTC	in port	—
Renfrew GBREN	Sep 25, 2026, 22:50 UTC	Sep 26, 2026, 22:05 UTC	23 h 15 min
Berendrecht BEBRT	Jul 26, 2026, 18:59 UTC	Jul 26, 2026, 21:31 UTC	2 h 32 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, 16:40 UTC	Draught change Reported draught went from 6.5 m to 8.5 m while in port at Liverpool. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1	High (75%)
Sep 26, 2026, 23:34 UTC	Draught change Reported draught went from 8 m to 6.5 m after leaving Renfrew. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1	Medium (55%)
