  1. Captain,

    I believe there will be Recovery Drills to practice the same, as we do it on-board drilling vessels after completion of each wells prior to start of a new one. We activate a controlled blackout which includes total shut down activated from bridge. Modern systems on 5th to 6th generation power plants are hard even to black out in a controlled manner..
