Also known as: Sea Explorer
Built by Ferus Smit in 1991
Technical Specifications
Live Tracking
Most time stopped at Patras — 40 h across 3 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.

Build Series
Sister hulls share a yard, segment, build year (±1) and deadweight (±3%) — the cleanest comparables for valuation. Derived in-house from our fleet register; coverage is limited to hulls carrying a recorded builder, so a series may be incomplete.
Operational Status
Stopped, anchored or moored on its latest broadcast — parked, not necessarily withdrawn.
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
Strong, corroborated adverse evidence — a detention, sanctions exposure or an AIS-gap / behavioural signal.
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.
Estimated
Other · summer draught 5 m · 9 t per cm immersion
Estimate only — modelled from deadweight (hull geometry) using a first-principles hydrostatic model, not measured hydrostatic tables. The design draught it is anchored to is unreliable across the fleet.
