Definitions

  • the present invention relates to a propulsion unit for a marine vessel that is intended to operate in icy waters and which has a propeller arranged to act on ice in the water to cut the ice.
  • the invention also relates to a marine vessel intended to operate in icy waters and which has a propulsion unit arranged to be able to act on ice to cut the ice.
  • An azimuthing thruster comprises a nacelle or capsule which is arranged as a separate unit attached to the outer part of the hull. At one end of the nacelle or capsule, a propeller is attached.
  • the motor for driving the propeller may be placed inside the nacelle/capsule or inside the hull.
  • the motor is usually an electrical motor and such an azimuthing thruster with an electrical motor inside the nacelle is usually called a pod.
  • the power for the electrical motor may in turn come from an inboard engine, usually a diesel or gas turbine.
  • the motor When the motor is placed inside the hull, the motor is often a diesel or diesel-electric motor and power may be transmitted to the propeller through a mechanical transmission.
  • the transmission may be an L-drive or a Z-drive.
  • L-drive there is a vertical input shaft and a horizontal output shaft.
  • Z-drive there is a horizontal input shaft, a vertical shaft and a horizontal output shaft with two right-angle gears.
  • An azimuthing thruster is typically connected to the hull in such a way that it can be rotated in any horizontal direction. Thereby, thruster or thrusters can be used for maneuvering such that a rudder is no longer necessary.
  • Azimuthing thrusters can actually give ships a better maneuverability than a system that uses a fixed propeller and a rudder.
  • Marine vessels having azimuthing thrusters may be used in icy waters and it has been suggested in for example US 5996520 that an icebreaker may be provided with steerable propulsion mechanisms.
  • a screw may be used to break ice that may block the path of the marine vessel.
  • azimuthing thrusters for example pods
  • azimuthing thrusters may be used as ice breaking devices. When azimuthing thrusters are used for icebreaking, the thruster(s) is/are turned such that the propeller faces the ice. The propeller is then used as a cutting tool to cut the ice.
  • a problem in connection with this is that the azimuthing thruster may be subjected to very high counter-forces in the horizontal plane.
  • a device which comprises a nozzle inside which a propeller is arranged.
  • a front piece acting as an ice crusher has been arranged in front of the propeller.
  • the front piece in that device serves only to protect the propeller and the propeller is not capable of acting on the ice to cut through an ice sheet or to cut an ice block since the propeller is arranged inside the nozzle and the front piece actively prevents ice blocks from reaching the propeller altogether.
  • US2010/0162934 discloses a method for improving the ice-breaking properties of a water craft by using an oblique aft end that is capable of breaking ice and allowing the movement of the water craft against the ice. The water craft then bores into the ice with its propeller ahead.
  • the invention relates to a propulsion unit for a marine vessel intended to operate in icy waters.
  • the propulsion unit comprises a propeller which is rotatable about a propeller axis in a plane of rotation for the propeller.
  • the propeller is mounted on a hub that is rotatable together with the propeller and the propeller is arranged such that the propeller can act on a piece of ice (e.g. a block or sheet of ice) in the water to cut the ice, even when the piece of ice has an extension that exceeds the diameter of the propeller.
  • the term "block of ice” will be used in the following to designate any piece of ice in the water, whether it is an irregular block, an ice-berg or a flat sheet of ice.
  • the hub is designed as a cutting element that is capable of cutting ice that encounters the hub.
  • the hub is shaped as a cone that extends in the direction of the propeller axis.
  • the hub extends beyond the plane of rotation of the propeller such that the hub can meet a wall of ice before the propeller meets the same wall of ice.
  • the hub may be provided with elevations that are arranged to cut ice that encounters the hub.
  • the elevated parts may be shaped as fins (i.e. flanges, ribs) or the elevations may be formed by nipples that give the hub a grainy surface.
  • the hub may have a polygonal cross section.
  • the hub may have a square cross section or a triangular cross section.
  • the propulsion unit is preferably an azimuthing thruster.
  • the invention also relates to a marine vessel intended to operate in icy waters.
  • the marine vessel has at least one propulsion unit which is preferably an azimuthing thruster with an elongate capsule/nacelle extending from a first end and a second end.
  • a propeller is mounted on the capsule/nacelle together with a hub for the propeller and arranged to be rotatable about a propeller axis in a plane of rotation for the propeller. Both the propeller and the hub are mounted at the first end of the capsule.
  • the propulsion unit is arranged to be capable of driving the marine vessel both in a forward direction and in a backward direction.
  • the propeller is further arranged such that it can act on a block of ice (e.g. a sheet of ice) to cut the ice, even when the block of ice has an extension that exceeds the diameter of the propeller.

  • vertical refers to what is vertical when the marine vessel rests in the water without being inclined to either the starboard side or the port side. This vertical axis about which the propulsion unit 1 may be rotated is thus substantially perpendicular to the propeller axis.
  • the substantially vertical axis about which the propulsion unit 1 may be rotated may deviate by up to 10° or about 10° from a perfectly vertical axis.
  • the propulsion unit 1 may thus be rotated in a plane that is essentially horizontal.

  • the propulsion unit 1 is in a position where the propeller 3 faces the hull 10 of the marine vessel 3.
  • the propulsion unit 1 has been rotated 180° about a vertical axis compared to the position of Figure 1. In this position of the propulsion unit 1 , the propeller 3 can be driven such that the marine vessel 2 moves towards the ice J. When the propeller 3 reaches the ice J, the propeller 3 will start to act on the ice to cut the ice.
  • the propulsion unit may thus cut a path through a block of ice that would otherwise have presented an obstacle for the marine vessel 2. Since there is no nozzle that surrounds the propeller 3, the propeller 3 is free to act on a block of ice J (for example an ice sheet or an ice berg) in the water to cut the ice, even when the block of ice J has an extension that exceeds the diameter of the propeller 3.
  • a block of ice J for example an ice sheet or an ice berg

  • the hub 4 is designed as a cutting element that is capable of cutting ice that encounters the hub 4.
  • the hub 4 will be capable of cutting the ice such that the horizontal force on the propulsion unit becomes significantly smaller.
  • These cutting elements comprise elevations, fins, nipples, polygonal cross sections and cut-out portions, among others, and it is to be noted that any of these embodiments or a combination thereof can serve the same purpose, namely that of cutting ice that encounters the hub 4. In this way, the load in the form of horizontal forces on the hub 4 is significantly reduced, resulting in a reduced risk of damages to the hub 4 as well as an increased ice-cutting ability and a smoother and more efficient passage through ice and icy waters.

  • the elevations 5 are formed by nipples that give the hub 4 a grainy surface.
  • the hub 4 may have a polygonal cross section. Such an embodiment is shown in Figure 9. As can be seen in Figure 9, the hub 4 has straight edges 13 that divide the surface of the hub 4 into four surfaces 14 that taper toward the end of the hub 4. The hub 4 will then have a sharp point that can penetrate the ice.
  • the elevations 5 in the embodiments of Figure 6 and Figure 8 can act on a block of ice to break up the ice such. Thereby, the horizontal force on the hub 4 and the propulsion unit 1 will decrease significantly.

  • there are four edges 13 such that the hub 4 will have a square cross section. It should be understood that other polygonal shapes are also possible, for example triangular (with three edges 13), pentagonal or hexagonal.
  • Embodiments with more than six edges 13 are also conceivable.
  • the elevations 5 are shaped as fins/ribs that have, from the end of the hub 4, an increasing height over the surface of the hub 4 until they reach a maximum point from which the height decreases.
