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.

Draught change

Reported draught went from 11 m to 8.9 m while in port at Mongstad. Voydar infers the ship probably discharged cargo.
