Summary
During drillship well completion, an erroneous watermist-release signal caused the fire and gas system to shut down and block all engines, preventing automatic blackout recovery. The emergency generator operated as designed. The vessel drifted off location, and the driller activated emergency disconnection at the red watch circle limit, securing the well.
