  • Ships for navigating in icy waters with improved propulsive performance
    Patent number: 9919775
    Abstract: Ships for navigating in icy waters are provided. Such ships include in the stern area a wedge which extends from bottom of the ship downwards transversely to the ship. The wedge may have a first surface inclined towards the bow and a second surface inclined towards stern with respect to a horizontal plane. These two surfaces can be connected to each other forming a lower edge of wedge. The wedge is at least partially arranged below waterline of the ship. The first inclined surface is dimensioned in such a way that in the case of forward motion, the first surface contacting the flow of water, generates a lift force in order to modify the longitudinal trim of the ship acting as a trim wedge. The second inclined surface also is shaped advantageously in the case of reverse motion in icy waters.

  • Ships for navigating in icy waters having improved propulsion performance
    Patent number: 9776691
    Abstract: Ships for navigating in icy waters having improved propulsion performance in open water and at the same time good maneuverability forward in icy waters are provided. Such ships include those having a bow area with a bulb adapted to generate a bow wave in phase opposition with respect to that generated by the ship's hull.
