ExxonMobil Canada Properties (ExxonMobil) has reported that on May 28, 2023, while completing maintenance on the knuckle boom crane on the Hebron Platform using a hydraulic pin puller, the hydraulic pin puller failed. This resulted in the puller rod being projected approximately 19 metres across the pipe deck striking the top of the northwest pipe deck handrail, and then dropping 21 metres to the deck below, landing on a walkway. The rod weighed approximately 6.8 kg.
There were no injuries. No barriers were in place for the path the rod travelled to the handrail, or for the drop path to the deck and walkway below. The incident had the potential for fatality.
ExxonMobil immediately ceased work in the area and has initiated an investigation into the root cause of the incident.
The C-NLOPB is monitoring ExxonMobil’s investigation of the incident.
