Definitions

  • the present invention relates to a steering and propulsion arrangement in a large ship suited for transoceanic traffic, which arrangement comprises a number of propulsion devices situated partly at the rear and partly at the forebody of the ship, in accordance with the preamble of claim 1 .
  • steerable rudder propeller devices which are driven either by a mechanical force transmission means or an electric motor arranged inside the device.
  • the device enables the turning of the propeller device about its vertical axis, and the propulsive force of the propeller can thus be turned in desired direction.
  • the propeller's rotational speed and direction of rotation may be adjusted and/or the angle of propeller blades changed.
  • Rudder propeller devices have been arranged at the forebody for instance in ferries that move in two directions. In these vessels the forebody and rear of the hull have been nearly identical. This kind of a hull configuration is not suitable for other types of vessels. Further, rudder propeller devices have been utilized in various kinds of landing crafts, the rear of which has generally been designed conveniently so that it enables the landing. In this case the rudder propellers, if any, at least some of which extend deeper down than the bottom of the vessel, are made retractable so that they can be protected when the aim is to steer the vessel as long as possible ashore.
  • the hull of large ships suited for transoceanic traffic has developed so that it is characterised by a bow being typically narrow like a wedge, the broadest part of the underwater hull being located amidships and the propellers being traditionally situated at the rear of the vessel.
  • Large ships refer here to ships, whose length is about 100 meters or more, whereby particularly such ship types as large cruisers are included, but also for instance icebreakers etc.
  • the manoeuvering of such vessels into harbour requires considerable propulsive efficiency at the forebody of the vessel.
  • the present equipment used for manoeuvering the bow produces propulsion, however, only sideways and can be used only when the vessel does not move or moves at low speed.
  • Rudder propeller devices have been arranged also at the rear of large ships to either partially or completely replace the actual rudder.
  • lateral drift might become a problem tending to impair the manoeuvrability of the ship due to the considerable lateral surface thereof.
  • a purpose of the present invention is to provide a novel steering and propulsion arrangement for large ships that normally move in one direction and are suited for transoceanic traffic, in which arrangement the above described problems are as far as possible eliminated.
  • An aim is that the solution can with advantage be utilised in various modes of operation and steering of a ship.
  • the forebody of the ship is provided with one or more steerable rudder propeller devices, which are arranged so as to substantially provide the steering and control of the ship, to produce a substantial part of the propulsive force pushing the ship forward at least substantially within all speed ranges, and in addition, arranged so that they do not extend, at least not significantly, below the base line of the ship.
  • the base line of the ship refers here to the lowest hull section determining the draught of the ship.
  • the solution according to the invention provides the bow of the ship with steerable propulsive power.
  • the ship bow can be manoeuvered when the ship stands still in harbour.
  • the propulsion of the fore propeller device is directed forward, whereby a considerable auxiliary power in forward direction is provided. If a malfunction occurs in the propeller device at the rear of the ship, the rudder propeller device at the front is still able to steer the vessel safely ahead.
  • the invention facilitates the manoeuvering of the bow when the ship does not move or moves ahead.
  • the propulsive force produced by the rudder propeller device can be fully directed, whereas a stationary bow-thruster produces only a transverse force.
  • the vessel's ability to survive damage in the propulsion devices or powerhouse has improved.
  • propulsion devices available also at the front, in addition to the propulsion devices at the rear.
  • the steering of the ship by means of rudder propellers situated at the front can be dynamic so that no lateral drift occurs when the ship steers in a passage.
  • the forebody of the ship i.e. in the underwater section of the hull at a distance from the base line of the ship, there is an area, which is designed sufficiently flat so that it enables the mounting and free turning of said one or more rudder propeller devices.
  • the bottom of the ship hull from said area towards the stern is smoothly shaped so that the rudder propeller devices, while the ship is moving ahead, can be directed according to the shape of the ship hull, whereby the flow behind the rudder propeller device towards the hull surface can be minimized accordingly.
  • said area is situated behind the bulb.
  • the rudder propeller devices at the forebody of the ship are dimensioned and arranged to be driven so that they cover, as needed, at least about 20% of the ship's total propulsive power in so-called harbour manoeuvering. Further, when steering ahead in sea traffic the rudder propeller devices at the forebody cover preferably at most about 10% of the ship's total propulsive power.
  • harbour manoeuvering there is as much power available as in manoeuvering arrangements provided with fore propeller passages.
  • much lower power levels are sufficient so as to make the flow no longer hit the hull, which is advantageous from hydrodynamic point of view. Higher power levels are possibly required in so-called “take home” situations, in which a part of the other power supply is for some reason not in use.
  • rudder propeller devices at the forebody of the ship.
  • the rudder propeller devices as such may be mounted at the forebody either side by side, one after the other or overlapping each other.
  • FIG. 1 shows a ship, seen from the side, where conventional propeller devices are situated at the front;
  • FIGS. 2-4 show how a rudder propeller device according to the invention, seen from the side, is arranged at the front of the ship, whereby the bow is shaped in a different manner;
  • FIGS. 5-8 show how one or several rudder propellers, seen from below, are arranged at the front of the ship.
  • FIG. 1 In a conventional solution according to the case shown in FIG. 1 there are three propeller devices arranged at the front of the ship on both sides, which devices affect only in the lateral direction of the ship, and contribute to the manoeuvering of the ship to quay and to its bringing off the quay respectively, and possibly to performing manoeuvering movements in the harbour area.
  • the bow-thrusters require a lot of power, which is of no use in the ship's normal steering ahead.
  • FIGS. 2-4 show how rudder propeller devices are arranged at the forebody of a vessel. Free turning of the rudder propeller device requires space and therefore the underwater hull requires modifications in comparison with traditional solutions.
  • FIG. 2 shows the use of a rudder propeller in a ship lacking a bulb. In FIG. 3 there is a small low bulb and in FIG. 4 a large deep bulb.
  • FIGS. 5-8 show how one or several rudder propeller devices can be arranged at the forebody either one after the other, side by side or overlapping each other. By adjusting the turning angle of the device the propulsion of the propeller is directed as the situation requires. Thus the ship can be steered ahead or astern, to quay, or the drift of the bow can be corrected in side wind or in curve.
  • the invention utilizes a known rudder propeller device already in general use, which device enables the directing of the propeller's propulsion around the vertical axis of the propeller device.
  • the propeller is rotated either by a mechanical force transmission means or an electric motor arranged inside the device, which are known as such and are therefore not shown in detail.
  • the bow can be manoeuvered by turning the propeller device.
  • the bow of the ship can be manoeuvered when the ship does not move at all or moves ahead.
  • the propulsion of the rudder propeller device is directed so that significant propulsive efficiency forward is produced.
  • the flow of the rudder propeller device is aligned with the hull surface so that the flow does not occur directly against the hull surface.
  • the vessel's ability to survive damage in the propulsion devices or powerhouse has improved.
  • propulsion devices available also at the front, in addition to the propulsion devices at the rear.
  • the invention facilitates the manoeuvering of the bow both when the ship does not move and when it moves ahead.
  • the propulsion provided by the rudder propeller device can be fully directed, whereas a traditional bow-thruster provides only a transverse force.
