Alert 09 – 26 Lifting Operation Results in Arm Injury (LTI)
After nippling up the BOP stack the crew was installing the flow line from the shale shaker. The assistant driller (IP) was standing above annular preventer trying to connect the flow line’s dresser sleeve with the bell nipple. He was holding the dresser sleeve with his left arm. The flow line was being lifted by the carrier hydraulic hoist, which created a blind lift. When he requested that the flow line be lowered a little, the night pusher ordered a new floor man to operate the carrier’s hydraulic hoist instead of asking the driller to operate it. The new floor man operated the hydraulic hoist excessively upwards, which squeezed the assistant driller’s left arm between the dresser sleeve and the beam located above the sleeve, causing a compound fracture to his arm.
