Alert 01 – 45 BOP Control System Uncontrolled Pressure Release Causes LTI
WHAT HAPPENED:
Relief Rig Manager, Driller and Floorman were removing a Nitrogen accumulator bottle from the manifold bank of 12 bottles. The men were using a chain tong to unscrew and remove the bottle when the bottle blew off the manifold. As the bottle blew upward, the chain tong apparently struck the Driller in the face and head causing severe injuries. The bottle then fell onto the Driller as he was lying on the floor.
