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.
Resolved from the live AIS destination. Distance is the real sea route (around land and through canals); the computed ETA is at the vessel’s passage speed. A destination is the crew’s stated intent, not a confirmed fixture.
Intelligence
Risk & Sustainability
An independent cross-check of the estimate above for Bulker (segment · size · age · market).
Estimate from $/dwt of similar-size, similar-age ships sold in the last 24 months. Indicative, not a certified valuation.
This ship has no verified emissions report. We estimate a band C from its segment, size and age (65% confidence).
Estimate, not a reported figure. Within one band 95% of the time on reported peers.

Safety Record
- INTENTIONAL BEACHING/GROUNDING/ANCHORING to avoid occurrenceMinorMay 17, 2023Windsor, ONTARIO (ON)
On 17 May 2023, the bulk carrier ''MARK W. BARKER'' reported a loss of propulsion while proceeding upbound in the Detroit River, ON. The bow of the vessel was intentionally brought ashore on the coast of Belle Isle, MI, USA, and anchored to assess the issue. A tug was ordered for assistance.
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
3 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→ · 3 h in port· draught 6.7→6.7 m
- no cargo change→ · 7 h in port· draught 6.7→6.7 m
- no cargo change→ · 4 h in port· draught 6.7→6.7 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
3 ports · 14 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.
- Port Inland· USA7 h1 call · 7 h avg
- Calumet Harbor· USA4 h1 call · 4 h avg
- Rouge River· USA3 h1 call · 3 h avg
Based on 3 completed calls observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Risk Score
No strong adverse signal on the components we could read for this hull.
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 9.72 m · 37.3 t per cm immersion
Estimate only — modelled from deadweight (deadweight only) 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=1.84 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.

Overview
About This Vessel
MV Mark W. Barker is a large diesel-powered lake freighter owned and operated by the Interlake Steamship Company. She is the first of the River-class freighters constructed for an American shipping company. MV Mark W. Barker is the first ship on the Great Lakes to be powered with engines that meet EPA Tier 4 standards. It is the first U.S.-flagged, Jones Act-compliant ship built on the Great Lakes since 1983. The ship is named after the president of the Interlake Steamship Company.
