On August 20th, 2021, at around 05:30 hours, the operational team removed the off-driller side (ODS) plate to connect the off drillers side MRC (mast raising cylinder) to lower the rig floor. Once the floorplate was removed, the air winch operator floorman stayed at the ODS air winch area, whereas his coworkers resumed other tasks. Suddenly the rig floor crew members (driller/ assistant driller and one Floor man) heard yelling from the substructure and realized that their coworker Air winch operator fell (fall distance 08.35 m height) and rested on the substructure area. The rig medic administered first aid to the Floor man before transporting him to Nimr PDO facility via MEDIVAC. The Floor man was conscious, oriented, and responding during his evaluation to Nimr clinic, then referred to Salalah hospital for further medical care. The floor man sustained head trauma (superficial wound), Pelvic fracture.
