Hull age

18 yr

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).

Kawasaki
op. unknown
In port since · low confidence

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.

Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.

Flag register0

A coverage-weighted blend of the 3 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. 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.

Signals are a current-state view: a flag clears once the vessel stops tripping its detector. These are screening indicators, not a substitute for your own due diligence.
