Live Tracking
Most time stopped at Võsu — 43 h across 1 stay.
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
How a hull like this loses value with age (today's market). The dot marks this ship at 19 yrs.
Estimate from $/dwt of similar-size, similar-age ships sold in the last 24 months. Indicative, not a certified valuation.
Open the full multi-model valuationThis ship has no verified emissions report. We estimate a band B from its segment, size and age (64% confidence).
Estimate, not a reported figure. Within one band 95% of the time on reported peers.
Compliance
On 03 April 2022, the product/chemical tanker "RIDGEBURY APOLLO", while under the conduct of a pilot, reported having sustained a propulsion failure while transiting the St. Lawrence River off Neuville, QC. The vessel anchored in the Îlets Dombourg anchorage, the crew carried out repairs, and the vessel resumed its voyage.
Recorded marine occurrences naming this vessel.
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 1 completed call 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.
Estimated
Tanker · summer draught 11.9 m · 51.1 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.
density DWT/GT=1.71 is consistent with declared tanker
Declared type is consistent with the class implied by the vessel’s size signals. Inferred via our shared size-based classifier.
