Definitions

  • the invention relates to an arrangement for steering a water-craft, which comprises at least one main propulsion device, which is arranged to push the water-craft forward or backward, and a number of steering propulsion devices, the pushing direction of which can be changed, in accordance with the preamble of claim 1 .
  • Water-crafts or vessels mean here all kinds of marine vessels, like for example cruisers, passenger ships, ice breakers and different cargo ships. Arrangements are already known, in which a water-craft is provided with two mechanically connected propellers with rudders behind them, two or three separate pod-propulsion devices or a propeller, behind which there is a contra-rotating propeller in a pod-propulsion device. The last mentioned has been disclosed in a WO-publication 01/54971, in which the pod-propulsion unit has been indicated by the reference numeral 4 and the propeller by numeral 3 .
  • the mechanical propeller arrangement has long shaft lines and shaft supports outside the hull of water-craft, which lead to a non-uniform wake field.
  • Steerable rudder-propeller devices or pod-propulsion devices have become more general in water-crafts. Since these devices are turnable, their thrust force can be utilized for steering of the water-craft.
  • a disadvantage with an electric arrangement of two or more pod-propulsion devices are the high costs, because efficient pod-propulsion devices require engine-driven generators together with their power control systems. These are expensive, heavy and large. For instance in RoRo vessels handling of cargo becomes more difficult because of the engine rooms and gaps required by the machinery, since these are partly located above the cargo deck. This means that several disadvantageous narrow parts are formed in the cargo space, whereby the rear end of the cargo space remains narrow. The heavy electric machinery leads further to a disadvantageous location of the displacement's centre of gravity in the longitudinal direction.
  • An object of the present invention is to eliminate the drawbacks of the prior art and to provide a novel solution advantageous as to its costs and enabling, where applicable, better utilization of the cargo space of the water-craft
  • the steering propulsion devices are arranged in the aft of the water craft on both sides of the said at least one main propulsion device so that the steering of the water-craft is continuously provided by means of the steering propulsion devices without any separate rudder means of the like to be functionally connected to said at least one main propulsion device.
  • the invention is based on the use of turnable steering propulsion devices in a water-craft so that they alone provide steering and additionally they participate in moving the water-craft forward.
  • a major part of the forward or backward propulsion is generated by a separate thrust device e.g. a large propulsion unit or large propulsion units.
  • An important advantage of the solution according to the invention is the fact that the upper end of the pod-propulsion devices fits below the cargo deck. Since the fully electric machinery of conventional large pod-propulsion devices is heavier and larger than the machinery to be utilized according to the invention, the invention allows for increased cargo capacity and handling of cargo becomes more efficient and easier. Furthermore, the solution is more economic and easier to put technically into practice than the known solutions.
  • the cargo deck can be lowered, the dimensions of the water-craft can be more economic and, compared with one centre propulsion device, two propulsion devices provide better reliability, which is important especially for the manoeuvrability of a passenger ship. Further, when separate main propulsion devices and steering propulsion devices are provided no supplementary output is used unnecessarily in manoeuvring.
  • the steering propulsion devices there is an even number of the steering propulsion devices and the propeller part of the steering propulsion devices is stationarily located outside of the hull of the water-craft.
  • the water-craft's at least one main propulsion device is located essentially in the aft centre part of the water-craft and the steering propulsion devices are positioned to the sides of the propulsion device being thus located in the lateral parts of the water-craft near the sideboards thereof.
  • a high efficiency is obtained when the main propulsion device is placed as far as possible in the water-craft's aft and no protruding parts increasing the resistance are needed in the rear side of the main propulsion device. Since no shaft bearings are needed, a uniform wake is created.
  • the steering propulsion devices provide an excellent manoeuvrability even in rough weather conditions, also at low speeds for instance less than 5 knots.
  • the output of the steering propulsion devices need not be high.
  • the output required by the steering propulsion devices is less than 50% of the common shaft output of the main propulsion device and of the steering propulsion device.
  • Shaft output means here the usual output obtained from the devices at maximum i.e. the nominal output taken by the main propulsion device and the steering propulsion device, which can be measured from the outlet shaft of the device.
  • the propulsion device itself is connected by means of a horizontal or almost horizontal shaft or shafts to a prime mover that may comprise one or more diesel engines and/or electric engines and/or gas turbines.
  • the steering propulsion devices are installed on both sides of the one or more main propulsion devices substantially near the outboard of the water-craft, they can be relatively small and can thus be installed under the cargo space of the water-craft. By doing so, a space can be formed under the cargo space for the maintenance and inspection of the steering propulsion devices.
  • FIGS. 1A and 1B show a water-craft provided with an arrangement according to the invention as a side view and viewed from below,
  • FIGS. 2A and 2B show alternative solutions relating to main propulsion devices and steering propulsion devices
  • FIGS. 3A and 3B show further alternative solutions relating to main propulsion devices and steering devices.
  • the arrangement is formed by a water-craft or a vessel 1 together with steering propulsion devices 2 and a main propulsion device 3 .
  • the steering propulsion devices even in number, have been placed quite close to the outboard 6 of the vessel.
  • Diesel engines indicated by the reference numeral 4 , serve as prime mover for the main propulsion device, the output of which is transferred to the main propulsion device by means of a shaft 5 .
  • the steering propulsion devices in the solution according to the invention need not be large, they do not require much space and the maintenance space 8 they need, in which maintenance staff 7 may go for checking, and when required, repairing the steering propulsion devices, is situated advantageously below the cargo space 10 . In this way the whole cargo space can be put into use and there are no previously needed narrowing parts, but the whole area can be utilized at maximum e.g. by loading onboard trucks and other cargo on wheels 9 .
  • FIG. 2A the upper view shows a main propulsion device 3 and a steering propulsion device 2 . Furthermore, a couple of examples of a steering propulsion device is shown in different positions 2 a and 2 b .
  • the steering propulsion device is in position 2 b , turning of the vessel into a desired direction is provided. If there is a need for boosting the turning, also the other steering propulsion device 2 is turned, respectively, into position 2 b simultaneously with the previous one.
  • FIG. 2B one main propulsion device 3 has been replaced by two separate main propulsion devices 3 a and 3 b.
  • FIG. 3A in addition to the steering propulsion devices 2 , there is provided an alternative solution to the traditional propeller and in this view a water-jet device 11 is used as a main propulsion device.
  • the FIG. 3B view is a supplementary variation of the FIG. 3A , in which there are more than one water-jets, in this solution three water-jets 11 a , 11 b and 11 c .
  • two water-jets 11 a and 11 c can be installed.
  • solutions also differing from the above described are feasible.
  • the solution can be applied to all kinds of water-crafts.
  • the solution makes possible a diversified driving profile.
  • the main mover of the steering propulsion devices can also be placed above the cargo deck e.g. around the smoke stack, in which case supplying of electricity also to other parts of the vessel is easy. In cruisers, this makes possible flexible distribution of electric power between the hotel load and the propulsion devices.
