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.

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.

When	What we observed	Confidence
Oct 1, 2026, 05:10 UTC	Draught change Reported draught went from 4.7 m to 6.6 m while in port at Nystad (Uusikaupunki). Seadar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1	Medium (65%)
Sep 28, 2026, 13:56 UTC	Draught change Reported draught went from 6.6 m to 4.7 m while in port at Kalmarsand. Seadar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1	Medium (65%)
