A coil tubing crew was running a fibre optic string into a production well. While placing the coil tubing into the well, the blowout preventor (BOP) separated from the wellhead. This resulted in damage to the coil tubing and loss of well control protection.
A crew was working on a BOP when the hydraulic fitting caps dislodged, fatally striking a worker in the head.
The rig crew arrived on location in the morning to discover that overnight the
BOP heater blanket had caught fire and extinguished itself when it completely
burnt.
An employee’s forearm was pinched by the BOP hydraulic operator resulting in two bones being broken.
The lubricator assembly sprung free of
the BOP stack and sprung backwards, striking the operator in the Genie lift in the face and
knocking him down.
A wireline crew was preparing to lift a wireline BOP control valve onto the well head. The control valve had been secured to a frame structure on the ground by means of two ratchet straps to prevent it from falling over. A new worker was assigned the task of hooking the valve to the crane hook by means of a lifting sling. The worker was seriously injured, when the wireline control valve fell over and knocked him to the ground.
The landing plate carrying the load of the bailer sections dropped down, crushing a
wireline worker’s fingers between the landing plate and top of the wireline BOP's.
As the snubbing operator was staging the coupler of joint #44 into the staging
chamber of the snubbing unit the lower stripping Quick Ram Change (QRC) rams were closed, the chamber was de-pressurized, and the upper stripping QRC rams were opened. Immediately after the upper QRC rams were opened there was a natural gas release from the closed annular Blow Out Preventer (BOP) on top of the snubbing stack.
