Summary
A motorman removed a pipe screen at the derrick board. As the drill string was lowered, his retractable fall-arrest cable tangled with the Kelly hose safety clamp. The blocks and top drive exerted force that parted the cable, resulting in a fatal fall of 75 feet (approximately 23 metres) to the rig floor.
