Abstract: At 1:30 a.m. on April 13, 2021, an employee was working 30 feet below ground on a Precision Drilling Rig floor running intermediate casing into the well by connecting each length of pipe as it was delivered to the rig floor. The pipe was being transferred between the ground and the rig floor using a Forum Energy Technologies Pipe Wrangler (hydraulic catwalk). The pipe wrangler malfunctioned which required the coworker to cease using the rig level controls and switch to using the ground level controls. While using the ground level controls, the operator must rely on a coworker on the rig floor to provide hand signals to indicate when to skate the pipe onto the floor. During this procedure, the employee was struck in the head by a pipe resting on the pipe wrangler and received a concussion and fractures and was killed.
