Alert 00 – 35 Missed Stand of Drillpipe Causes an LTI


While running in the hole with 3- ½” drill pipe, the floorman who was relieving the derrickman, missed latching a stand and it fell across the derrick. As the derrickman returned to the board, the driller and a floorman wrapped an air hoist cable around the stand to pull it back to the derrickboard. The stand had wedged between a derrick beam causing some problems in getting the stand to come loose. The stand of pipe finally came free and whipped across the derrick striking the offside foot stand. This caused the foot stand to hinge upward, striking the derrickman in the left leg. The derrickman suffered a broken leg.
