GARDNO

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).

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.
