only the front 55 feet (17 meters) of the vessel pointing up out of the water, with bulkheads becoming floors. When flipped, most of the buoyancy for the platform is provided by water at depths below the influence of surface waves, hence FLIP is a stable platform mostly immune to wave action. At the end of a mission, compressed air is pumped into the ballast tanks in the flooded section and the vessel returns to its horizontal position so it can be towed to a new location.[1] The ship is frequently mistaken for a capsized ocean transport ship.
