Alert 11 – 24 Three Dropped-Object Incidents Occur While Tripping Out of the Hole


Three incidents resulted in separate dropped-object incidents. They are:
1. While the driller was picking up the pipe in the slips, the hydraulic hose on the elevators came loose and the elevators opened.
2. During a trip out of the hole the driller was in the process of setting back a stand of pipe and he opened the hydraulic elevators before the stand was fully set back. This resulted in dropping the stand on the rig floor.
3. Following jarring operations, when pulling out of the hole, the cover on the elevator hydraulic fittings came loose and fell toward the floor. The derrickman noticed the cover had moved and caught it.
