Safety Record

Marine casualties4

GroundingSerious
Sep 24, 2023Farlingers Point, ONTARIO (ON)
On 24 September 2023, the bulk carrier "NACC ARGONAUT" reported having run aground in the St. Lawrence River off Cornwall, ON. An ingress of water was found in the No. 1 port ballast tank. The tugs "OCEAN INTREPIDE" and "OCEAN K. RUSBY" freed the vessel and assisted it to an anchorage off Île Dickerson, QC.
Personnel CasualtySerious
May 3, 2023Cleveland, Outside Provincial Boundaries
On 03 May 2023, the cement carrier "NACC ARGONAUT" reported a crew member having sustained a serious injury during mooring operations in Cleveland, OH, US. The crew member was evacuated and hospitalized.
Machinery FailureMinor
Apr 27, 2021Quai de Rimouski, QUEBEC (QC)
On 27 April 2021, the cement carrier "NACC ARGONAUT" reported the failure of its main engine sea water cooling system in the St. Lawrence River off Rimouski, QC. The vessel proceeded at a reduced speed, the crew carried out repairs, and the vessel resumed its voyage.
Machinery FailureMinor
Sep 5, 2020Neuville, QC, QUEBEC (QC)
On 05 September 2020, the cement carrier "NACC ARGONAUT", under the conduct of a pilot, reported a problem with its controllable pitch propeller servo system. The vessel anchored off Neuville, QC, to carry out repairs before resuming its voyage towards Côte Ste-Catherine, QC.

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.

Hull age72

Flag register50

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.
