Alert 12 – 12 Lack of Inspection Procedures Results in Dropped Blocks
WHAT HAPPENED:
The crew was tripping in to the well when the driller pushed down on the brake handle and realized that he had lost brake control. The block came down hitting the well head and rested next to the well. When the block dropped to the ground, it caused a backlash in the drill line. This allowed the drill line socket to release from the drum where it hung up in the sheave guard in the crown and caused damage to the guard.
