Alert 09 – 35 Dropped Stands of Drill Pipe Results in Incidents
While the rig crew was tripping drill pipe into the hole the derrickman missed latching a stand of 3½” drill pipe and it was dropped across the derrick. In an effort to return the stand to the derrick man, the floor crew used the driller’s side rig floor winch. They wrapped the winch’s cable around the stand, anchored it to the rig floor
near the V-door opening and began to pull it back to the derrickman. As the stand was being pulled back toward the derrickman, it slid or lifted up and went out the v-door, falling to the yard below.
