The Transportation Safety Board of Canada (TSB) has sent a team of investigators to probe Monday’s sinking of two tugboats on the Saint Lawrence River, marking the TSB’s second deployment this week in the area.The two tugboats, Lac Manitoba and LCM 131, sank within just a few hours of each other near Cornwall, Ontario.
Photos of the Lac Manitoba show the vessel being pinned against a construction barge in strong current, eventually causing the vessel to roll over and drift and downriver. The sinking of the LCM 131 capsized and sank just a few hours later in the same area. No casualties were reported in either incident.
The TSB says its team will gather information and asses the two occurrences.
The incidents follow the grounding of the MV Tundra bulk carrier on the St. Lawrence River off Summerstown, Ontario. That incident is also being investigated by the TSB.
