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 |
|---|---|---|
| Sep 30, 2026, 16:45 UTC | Draught change Reported draught went from 7.3 m to 5.8 m while in port at Kallo. Seadar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | Medium (65%) |
| Sep 27, 2026, 18:58 UTC | Draught change Reported draught went from 8.2 m to 7.3 m while in port at Kallo. Seadar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | Medium (65%) |
