2025 Second Alert HiPo#10 laydown the jar
During the Running in Hole (RIH) of the 8-1/2” BHA, the crew used the power catwalk skate and winch line to place the drilling jar in the mousehole. The floor man noticed the winch line was snagged on the monkey-board finger. To free the line, the floor man slacked the winch line, allowing the floor man to attempt removal, but without success. The driller then tried to lower the drilling jar back to the catwalk. As he moved the power catwalk skate, slack in the winch line caused the jar to shift toward the driller side of the V-door. When the winch line Tightened, the floor man, still holding the line, experienced a sharp jerk, causing Him to lose balance and slide down on the V-door to the catwalk
What should you do when a task changes unexpectedly? Why is it critical to close the V-door before handling winch lines? How can we prevent complacency during repetitive tasks? What steps ensure effective communication? How do you apply Stop Work Authority when you see unsafe Acts/conditions? How do you ensure effective supervision during critical activity?
The floorman attempted to free the snagged winch line from the monkey board finger. Winch line entangled in monkey-board finger; risk not reassessed. The floorman was positioned close to the V-door, which constituted a line of fire. Communication gaps: Catwalk was operated without confirming the area was clear, leading to a sudden line tension that caused a floorman to lose balance and fall. Stop work authority was not utilized; no one intervened when they observed the floor man near the V-door. There was insufficient supervision
