HOLGER G

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. Hoek Van Holland

   op. unknown

   In port since
2. Port of Rotterdam

   no cargo change

   → · 3.0 days in port· draught 3.5→3.2 m
3. Schiedam

   Discharged

   → · 15 h in port· draught 5.7→3.5 m
4. Ahus

   no cargo change

   → · 2.9 days in port· draught 3.7→3.7 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.
