Derived from the AIS track — runs of near-zero speed (anchored, moored or drifting) snapped to the nearest port. Builds up as we observe the vessel.

Read from the single most-recent AIS broadcast we hold for this hull — we keep no position history, so this is a point-in-time posture, not a dwell inference. Derived in-house from our own AIS feed; weight it by the broadcast age above.

Port calls

1 recent · AIS-detected

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. · 30 h in port· draught 3.74.5 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.

Where it waits

1 port · 30 h total

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.

  1. 30 h
    1 call · 30 h avg 1 load

Based on 1 completed call observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.

A coverage-weighted blend of the 2 components we could read for this hull — the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
