ABSTRACT:
An improved vessel for use in ice-covered waters has a motion inducing tank disposed in its hull at a location spaced from the even-keel center of buoyancy of the hull. Ports communicate from the lower extent of the hull to the exterior of the hull below the hull load waterline for flow of water into and out of the tank in response to pressure in the tank being different from ambient pressure outside the hull. The tank extends vertically in the hull from a lower end located below the hull load waterline to an upper end located above the waterline substantially as far as the location of the ports below the load waterline. Airflow devices are coupled to the upper extent of the tank and are operable alternately for generating superatmospheric and subatmospheric air pressure in the tank. The airflow devices include an air pressurizing device having a suction connection and a discharge connection. Ducts are provided for coupling the suction connection separately to the upper extent of the tank and to atmosphere, and also for coupling discharge connections separately to the upper extent of the tank and to atmosphere.
