Alert 00 – 07 Rig Damaged by Drill Collar Release from Fingerboard
WHAT HAPPENED:
Two 120’ (36m) stands of 8-1/4” (20.6 cm) Range II drill collars were released from the fingerboard. The two stands struck beams on the opposite side of the derrick and broke in half at the middle connections. One of the upper 60’ (18m) doubles penetrated the driller’s cabin. Fortunately, there were no injuries, but the rig incurred downtime in addition to property damage.
