Marine investigators in Canada have released a report detailing the causes behind a December 2024 collision in Squamish Harbor, British Columbia, involving the tug Haisla Northwind, the barge BSG Lubricator, and the workboat Triton 1. The incident occurred in the marine safety zone of the Woodfibre LNG Project site while the tug was transporting provisions to the Isabelle X, a floating accommodation for project workers. The collision resulted in the Triton 1 capsizing and sinking, with its operator rescued from the water and treated for hypothermia. Minor pollution was reported, but no damage occurred to the tug or barge.
The Transportation Safety Board of Canada (TSB) identified gaps in situational awareness and communication breakdowns as primary factors contributing to the collision. Visibility issues from the tug’s wheelhouse, obstructed by onboard structures, hindered the master’s ability to see the Triton 1. Additionally, bright lights from the construction site and nearby vessels created glare, making it difficult to distinguish the workboat’s navigation lights.
Investigators found that the operator of Triton 1 did not receive an arrival message on the VHF radio and was distracted by a cellphone call, leading to a lack of awareness regarding the approaching tug and barge. In response to the incident, organizations involved have implemented safety measures, including enhanced communication protocols, improved vessel-tracking equipment, and restrictions on barge movements to daylight hours.
