Safety Record
- INTENTIONAL BEACHING/GROUNDING/ANCHORING to avoid occurrenceModerateMay 25, 2024Babys Point, ONTARIO (ON)
On 25 May 2024, the bulk carrier "THUNDER BAY" reported having sustained a total failure of its engine on Lake St. Clair off Seaway Island, ON. The vessel proceeded at a reduced speed to an anchorage off Windsor, ON for repairs.
- TOTAL FAILURE OF ANY MACHINERY OR TECHNICAL SYSTEMMinorJun 3, 2022Cap Saint-Michel, QUEBEC (QC)
On 03 June 2022, the bulk carrier "THUNDER BAY", while under the conduct of a pilot, reported experiencing engine issues while transiting the St. Lawrence River off Cap Saint-Michel, QC. The vessel anchored in the Pointe-aux-Trembles, QC anchorage where the crew carried out repairs and the vessel resumed its intended voyage.

On 11 July 2016, the bulk carrier "THUNDER BAY" allided with the wall of the Welland Canal's Lock #8 off Port Colborne, ON. The vessel sustained damage to its hull and proceeded to the dock 18-2 for cargo unloading and repairs.

Build Series
Sister Vessels
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
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
1 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→ · 7 h in port· draught 7.1→7.1 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
1 port · 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.
- Port Colborne· Canada7 h1 call · 7 h avg
Based on 1 completed call observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Risk Score
Some elevated factors — typically age or a lower-graded flag — but no acute ship-specific flag.
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 8.1 m · 42.1 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=1.41 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
Thunder Bay is a Trillium-class lake freighter cargo vessel, built and launched in China in 2013. The ship is owned, and operated on the Great Lakes, by the Canada Steamship Lines (CSL). Like her three sister ships in CSL's Trillium class, Baie St. Paul, Baie Comeau, and Whitefish Bay, the vessel is a self-unloading bulk carrier, with a conveyor belt on a long boom that can be deployed over port or starboard sides.
