On 16th June 2021 at 1740 hrs, operations was picking up a 1.5m DP pup joint. While the Floorman was operating the hydraulic winch of the substructure and lifting the pup joint through the V-door, as the pup joint was about to cross the V-door to the rig floor, it swung and got caught underneath the substructure beam. The Driller and another Floorman were on the rig floor. The Driller observed that the winch line chain was in high tension and immediately attempted to stop the winch operator but the wire rope sling parted at about 17m height above the rig floor (weight of the winch line ball is 6 kgs at 13m) and fell through the V-door with the chain linked on it while other end of the winch line came out from the crown sheave and landed on the rig floor. Nobody was hurt as the red zone was observed at the time of the incident.
