Marine transportation safety investigation M24P0265
The occurrence
On 18 December 2024, the tug Haisla Northwind was pushing the barge BSG Lubricator when it collided with a workboat (Triton 1) at the Woodfibre LNG site on Howe Sound, near Squamish, British Columbia.
Following the collision, the workboat sank, causing the sole occupant to enter the water. The occupant was rescued by a nearby vessel and was later treated for hypothermia.
While the tug and barge sustained no damage, minor pollution was observed, and spill booms were deployed to contain it. The TSB is investigating
