On 11/9/1999 , the vessel ALCOR (Official Number 5735) was involved in a grounding - under power (non-intentional) in CAP TOURMENTE, QUE., QUEBEC (QC).

The vessel, with 25 persons on board, experienced the incident while engaged in regular operations. Fortunately, the ship was able to continue its voyage. No injuries or fatalities were reported, and there was minor pollution.

This incident was officially recorded by Transport Canada on 10/4/2001 . Weather at the time was reported as clear with winds from the NE at 10.00 knots.

On 09 November 1999, the loaded bulk carrier Alcor was upbound for Trois-Rivières, Quebec, on the St. Lawrence River, under the conduct of a pilot. At 1444 local time, while undertaking a course alteration to starboard, the vessel ran aground near the eastern end of Île d'Orléans. A refloating attempt the next evening succeeded in freeing the vessel, but only briefly, and the vessel grounded a second time near the initial grounding position. The Alcor sustained major hull damage near midships due to bending forces incurred during successive low-tide cycles.

The damaged hull was temporarily repaired and roughly half of the cargo was discharged onto smaller vessels. On December 5, the Alcor was refloated and conducted to the port of Québec. It was declared a constructive total loss.

While the Alcor was being refloated and later, while the vessel was upbound with the assistance of tugs, the Traverse du Nord section of the river was temporarily closed. The closure caused several downbound vessels to anchor upriver. The subsequent re-opening of the channel resulted in a confluence of vessels wishing to depart their anchorages. During this time, a near-collision occurred between the tanker Eternity, under way, and the container ship Canmar Pride, at anchor.
