EEMS SERVANT

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. 's-Gravendeel

   Loaded

   → · 13 h in port· draught 2.9→3.7 m
2. Delfzijl

   Discharged

   → · 8 h in port· draught 4.1→2.9 m
3. Thyboron

   no cargo change

   → · 9 h in port· draught 3.0→3.0 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.
