Alert 07 – 08 Dropped Drill Pipe Stand Results in Near Miss
WHAT HAPPENED:
While tripping 5-1/2” drill pipe into the hole, a roughneck was working the monkey board and lost control of a stand. The stand struck the Top Drive System (TDS), glanced off and came to rest against the derrick. The impact of the stand against the Top Drive System sheared off a “Stand Off” roller, which fell approximately 75’ to the rig floor and landed 3’ from the “Dog House”. The roller that fell to the deck weighs 25 lbs, is 3 ½” in diameter in the center, and has 5” diameter ends.
