Designed for use alongside oil platforms under construction as a temporary place for workers to live, the Offshore Accommodation Vessel—as it’s called—features a U-shaped water tank lining its hull. The tank is only partly filled with water, though. And by controlling the amount of air pumped into either side of the tank, a gentle inner wave is created which can be used to counteract the motions of a rolling sea, stabilizing the ship.
