A training exercise conducted and timed by the tool pusher on a drilling rig. The blowout alarm is rung without warning the driller. The driller pulls the kelly out of the rotary and shuts off the mud pumps. Crew members go to the BOP control panel, choke manifold and the diller´s side of the rig at ground level to operate the remote BOP controls. The derrickman goes to the accumulator, and the driller orders the BOP closed.
