Technical Specifications
Overview
Waxholms Ångfartygs AB, commonly referred to as Waxholmsbolaget, is a shipping company owned by Stockholm county council and is responsible for the seaborne public transport in the Stockholm archipelago and Stockholm harbour. The company, which is mostly tax-funded, carried about 4.3 million travellers in 2003, covering a region from Arholma in north of the archipelago to Landsort in the south. The company owns 20 archipelago boats, and four boats for the inner-city Djurgården ferry line. The operation of the ships is handled by several contractors, some of whom also operate their own ships on behalf of Waxholmsbolaget.
Live Tracking
Most time stopped at Stockholm — 5 d across 5 stays.
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.
Intelligence
AIS-derived from our live feed.
Operational Status
Making way at sea speed on its latest broadcast.
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.
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.
Based on 2 completed calls observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
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.
