2025 Second Alert HiPo#26 During nighttime seismic operations, a vibrator operator collided power line pole
During nighttime seismic operations, a vibrator operator collided with a 33KVA overhead power line pole, causing structural damage to the pole and insulators. No injuries occurred, but the incident led to power disruption.
Fatigue Management: What indicators of operator fatigue could we have detected earlier, and what measures can prevent micro-sleep during operations? Supervision: Why was the operator left alone near OHPL, and how can we ensure continuous monitoring in high-risk zones? Risk Assessment: Why did our risk assessment and MOPO fail to include specific controls for OHPL proximity, and how can we strengthen these processes?
The vibrator operator experienced a micro sleep while driving the vibrator, leading to a direct collision with the power line pole Poor supervision – operator was alone near OHPL as he assigned vibrator pusher was not near to monitor or intervene. Risk assessments and MOPO lacked specific controls for OHPL proximity. The operator drove straight toward the pole instead of following the standard VP approach pattern, which typically involves maneuvering to create enough turning space.
