Alert 11 – 14 High Potential Near Miss – Dropped Object


The drill crew was tripping in the hole with 5 ½ inch drill pipe. The derrickman attempted to place a stand of drill pipe in the elevators but missed and the stand was dropped across the derrick. When the stand was being recovered it was pulled back to the fingers, it struck the fingers causing shaking and vibration to the derrick and monkey board. The motion caused a 12 lb. (5.4kg) speaker mounted at the back of the monkey board to break loose at the junction box. The derrickman was standing next to the speaker at the time the stand struck the fingers and was able to catch the speaker as it fell and it was brought down to the rig floor.
