Safety Record
- TOTAL FAILURE OF ANY MACHINERY OR TECHNICAL SYSTEMMinorMar 17, 2026Bar Point, ONTARIO (ON)
On 17 March 2026, the bulk carrier "HERBERT C. JACKSON" reported having sustained a total failure of its steering system in the Detroit River off Amherstburg, ON. The crew used the bow thruster to maintain the steerage and the vessel resumed its voyage.
Recorded marine occurrences naming this vessel.
Operational Status
Activity
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.
Port calls
2 recent · AIS-detectedArrivals, 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).
- no cargo change→ · 4 h in port· draught 6.4→6.4 m
- no cargo change→ · 2 h in port· draught 7.6→7.6 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
2 ports · 7 h totalTime-in-port summed by port from the AIS-detected port-call history — the ports this vessel has spent the most time at, longest first.
- Detroit· USA4 h1 call · 4 h avg
- Port Inland· USA2 h1 call · 2 h avg
Based on 2 completed calls observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Risk Score
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
Capacity & Classification
Bulker · summer draught 6.3 m · 34.1 t per cm immersion
Estimate only — modelled from deadweight (deadweight regression) 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=2.03 is consistent with declared bulker
Declared type is consistent with the class implied by the vessel’s size signals. Inferred via our shared size-based classifier.
