    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.

    Abstract: A vessel and method for breaking ice drifting in a predominant direction relative to an offshore installation such as a drilling vessel. The vessel is used to deploy an anchor in a position at a distance from the offshore installation and in a direction which, seen from the offshore installation, is substantially in parallel with the direction of movement of the ice. By means of the machinery of the vessel, the direction of the anchor line is adjusted and so is the orientation of the vessel relative to the anchor line to the effect that the propellers can be used to crush and dispose of the ice without using motive energy to hold the vessel against the pressure of the ice.

    Abstract: An icebreaking vessel (10) with icebreaking reamers (23a, 23b) at each side and, in connection with the reamers, propellers (24a, 24b) for the propulsion of the vessel. The icebreaking vessel can be formed by attaching a detachable icebreaking bow section (31) equipped with reamers and propellers in connection with them to any such ship (30) which is not an actual icebreaker and which has corresponding joint members for attaching the detachable bow section to the ship.

    Abstract: A wide beam, multi-hull icebreaker and method of operation thereof for opening a wide track through which large commercial vessels may traverse is disclosed. The icebreaker includes a plurality of hulls spaced apart and arranged generally in parallel to one another, with each of the hulls including a bow thereon configured to break through a sheet of ice through which the icebreaker traverses. The spaced apart hulls define at least one channel therebetween into which ice broken by the hulls is routed, and the hulls are spaced apart a distance such that a beam of the icebreaker is as wide as a beam of a commercial vessel it is servicing. A conveyor system may be included on the icebreaker that removes broken ice from the channel(s) between the hulls and casts it to the side of the track to leave a less dense track of broken ice.

    Abstract: The invention relates to a watercraft having improved characteristics for travel in ice, particularly an icebreaker, supply vessel, cargo vessel or corresponding, which watercraft has a hull, which has at the stem portion a propulsion and steering arrangement, which is mainly responsible for movement and steering of the watercraft and which includes at least one skeg-like projection, in which is located at least one propeller device. In accordance with the invention, said skeg-like projections comprise two units located on different sides of the centre line of the hull. Said propeller device is located at the stem end of the skeg-like projection. In addition, the skeg-like projection has between the propeller device and the hull of the watercraft, in the longitudinal direction on the skeg-like projection, one or more thruster devices to provide a water flow mainly transverse in relation to the hull.

    Abstract: A device for ice-breaking with a vessel has two functionally separate upper and lower elements of different widths. The upper, wider element is situated next to the water line for breaking unbroken ice, and the lower, narrower element is situated below the upper element and for transporting broken ice sideways and under the unbroken ice. The upper wider element has a flat lower portion abaft an inclining front part with a small frame angle and breaks ice downward when moving ahead, and a flat stern part with a small frame angle and breaks ice downward when moving astern. The lower element has vertical side portions which in the forebody and the afterbody have a marked wedge-shape and shove broken ice sideways. Transport of broken ice sideways and astern can be augmented by bow propellers and wing propellers.
