SCOT LEADER

Arrivals, time in port and the load/discharge inferred from the draught change — detected from AIS track history. An open call means the vessel is still in port (no departure observed yet).

1. Karlshamn

   Discharged

   → · 2.5 days in port· draught 5.9→4.0 m
2. Kiel Canal

   no cargo change

   → · 2 h in port· draught 5.9→5.9 m
3. Upnor

   Discharged

   → · 36 h in port· draught 5.6→3.9 m

Method: each call is a run of fixes inside a port’s geofence confirmed by a stop (or an AIS gap); load/discharge is the sign of the draught delta over the call. Indicative — arrivals before our AIS history began read from the first observation.

Time-in-port summed by port from the AIS-detected port-call history — the ports this vessel has spent the most time at, longest first.
