Summary
A toolpusher aboard Deepwater Champion suffered a head laceration when a top-drive link tilt stop plate fell 13 feet. The investigation attributed pivot-screw shearing to the plate’s abnormal orientation and loading. It examines unclear retention-sling guidance, incomplete upgrade kits and inspection records that omitted plate orientation.
