Best Practices for JSA Reviews on Fatigued Drill Crews

A JSA for a slips-and-elevators task gets signed off in 72 seconds on day 19 of a hitch, copy-pasted from the previous tour's template. The hazard identification is generic. The review participants are half-asleep. The accident report two days later calls the JSA "adequate but not executed with full engagement." That gap is where the fatigue hides.

On a jackup drilling in the Gulf of Mexico, a slips-and-elevators JSA closed in 72 seconds on day 19 of a 21-day rotation. The document was populated by the assistant driller from a template used 14 times in the previous week, the hazard list copied without edit, and the crew signatures collected one by one as they rotated off coffee break. Two tours later, an elevator latch swing struck a floorhand's hard hat.
