The present invention relates to a manoeuvring system. Certain embodiments of the present invention relate to a manoeuvring system for a vessel such as a ship, a motor boat, a sailing boat or a yacht.
Further, the present invention relates to an arrangement comprising a vessel and a manoeuvring system.
Even further, the present invention relates to a use of a manoeuvring system.
Furthermore, the present invention relates to a method of manufacturing a manoeuvring system.
Additionally, the present invention relates to a computer readable memory.
Different manoeuvring systems are known by means of which a user is able to manoeuver or navigate a vessel, for example in a harbour. Document WO 2019/086762 A1, for example, discloses a system, a software program product and a method for manoeuvring a boat. A plurality of water nozzles is provided on the boat. Further, a plurality of pumps is operated by a power source of the boat. The plurality of pumps is primed continuously to reduce response time to control the plurality of pumps and each of the plurality of pumps is connected to one water nozzle. A plurality of sensors is configured to monitor the state of motion of the boat. Further, an artificial intelligence module or control unit is in communication with the plurality of pumps, the plurality of sensors, and/or the plurality of water nozzles. The artificial intelligence module is configured to keep the boat in a stationary standstill or on a chosen course of motion.
U.S. Pat. No. 6,142,841 A, for example, further describes a maneuvering control system which utilizes pressurized liquid at three or more positions of a marine vessel in order to selectively create thrust that moves the marine vessel into required locations and according to chosen movements. A source of pressurized liquid, such as a pump or a jet pump propulsion system, is connected to a plurality of distribution conduits which, in turn, are connected to a plurality of outlet conduits. The outlet conduits are mounted to the hull of the vessel and direct streams of liquid away from the vessel for purposes of creating thrusts which move the vessel as required. A liquid distribution controller is provided which enables a vessel operator to use a joystick to selectively compress and dilate the distribution conduits to orchestrate the streams of water in a manner which will manoeuver the marine vessel as required.
Document WO 98/22337 A1, for example, discloses a hydraulic system for the control of boats, ships and crafts in general that comprises nozzles opposed at the end of the stem, having a Venturi tube throttling or an internal diameter reduction by means of flanges, so as to be able to determine, following to the outlet of the fluid under pressure, the movement by reaction of the front part of the boat and therefore to perform immediate leftward or rightward curvings according to the nozzle used, and/or corresponding nozzles, placed nearby the stern and with similar backward function, while the operating for hydraulic reaction of both nozzles placed on the same side determines the parallel movement of the whole craft, for coming alongside to quays or for performing other manoeuvres.
U.S. Pat. No. 6,394,015 B1 further describes a technique for reducing or preventing the impact force between two small boats or between a small boat and a large boat about to collide. The technique involves the blast of high pressure water from one of the boats against the other to push it aside. The water blasts would be directed against the hull of the threatening boat. A distance sensor can automatically initiate the water blasts by sensing the closeness between the two boats. For manual operation of the water blasts, a switch can be closed at any time that one so wishes, to avoid the collision. One or more adjustable nozzles on water outlets, operated remotely in different directions, enable the boat's pilot to direct the blasts where they would be most effective in averting a collision. Thus, the three options for the boat's captain are: 1. Manually switching on motor-driven pumps to blast water out of fixed nozzles, 2. remotely, angularly positioning nozzles from side to side or up and down, 3. automatic operation by allowing distance sensors to determine when to blast water against the hull of a threatening boat.
In view of the foregoing, it would be beneficial to provide a manoeuvring system, wherein safety of a vessel equipped with the manoeuvring system can be improved.
The invention is defined by the features of the independent claims. Some specific embodiments are defined in the dependent claims.
According to a first aspect of the present invention, there is provided a manoeuvring system comprising at least one unit comprising a channel having a longitudinal axis and comprising at least one water intake opening, at least one water nozzle arranged within the channel and configured to guide a water flow through the at least one water intake opening at an angle relative to the longitudinal axis and in a plane perpendicular or substantially perpendicular to the Earth's normal, at least one piping connected to the channel at a first end and connected to the at least one water nozzle at a second end, and at least one pump arranged between the first end and the second end and configured to control a water flow through the at least one water nozzle.
Various embodiments of the first aspect may comprise at least one feature from the following bulleted list:
According to a second aspect of the present invention, there is provided an arrangement comprising a vessel and a manoeuvring system according to any one of claims 1-11.
According to a third aspect of the present invention, there is provided a use of a manoeuvring system according to any one of claims 1-11 in connection with mooring of a vessel, compensating a motion of the vessel caused by an external force, keeping position of the vessel, moving the vessel into a required direction, or preventing collision of the vessel with an object.
According to a fourth aspect of the present there is provided a method of manufacturing a manoeuvring system, the method comprising providing a hollow structure having a longitudinal axis and comprising at least one water intake opening, thus forming a channel, arranging at least one water nozzle within the channel, wherein the at least one water nozzle is configured to guide a water flow through the at least one water intake opening at an angle relative to the longitudinal axis and in a plane perpendicular or substantially perpendicular to the Earth's normal, connecting at least one piping to the channel at a first end and the at least one piping to the at least one water nozzle at a second end, and arranging at least one pump between the first end and the second end, wherein the at least one pump is configured to control a water flow through the at least one water nozzle.
According to a fifth aspect of the present invention, there is provided a non-transitory computer readable medium having stored thereon a set of computer implementable instructions capable of causing a processor, in connection with the arrangement according to claim 12, to receive a user input from a user via a user interface, receive a signal from at least one sensor and/or receive a signal from an external positioning system, calculate a required water flow through at least one water nozzle of a manoeuvring system, and transmit a control signal to at least one pump of the manoeuvring system.
Considerable advantages are obtained by means of certain embodiments of the present invention. A manoeuvring system for a vessel such as a motor boat is provided. According to the present invention, the number of openings in the hull of a vessel can be limited, as water is able to flow through the water intakes into the system and water can then be ejected through the water intake openings via a plurality of nozzles. For example, only four openings in the hull are necessary when providing the vessel with four units, wherein each unit has one water nozzle. An additional water intake in the hull is not required, thus improving safety of the vessel.
One pump is provided for each nozzle and the pumps can be primed in order to reduce control response time, thus resulting in a system responding immediately to a command from a user. Thus, stepless or virtually stepless control of the propulsion is possible due to use of a plurality of pumps in the system, wherein each pump has a sufficient response time.
Installation of the manoeuvring system in accordance with the present invention is further easy to perform and the system can be manufactured in industrial scale.
Additionally, cavitation can be avoided or at least reduced during use of the system due to a relatively large cross-sectional area of the water intake openings in comparison to the cross-sectional area of the piping systems and nozzles.
Furthermore, the system allows navigating a vessel, for example during mooring, without use of a main engine. Even unexperienced users are able to easily control the system via a user interface. According to certain embodiments, the present invention is further beneficial in connection with mooring of a vessel, compensating a motion of the vessel caused by an external force, keeping position of the vessel, moving the vessel into a required direction, or preventing collision of the vessel with an object.
According to certain embodiments of the present invention, system may be remotely operated by a user via a mobile device such as a smartphone or tablet computer.
In this document, the term “channel” is used. The “channel” can be either a recess having only one opening through which water can flow into the recess or a tunnel having two openings at opposite sides through which water can flow into the tunnel.

The manoeuvring system 1 comprises a hollow structure 10 forming a channel 2 having a longitudinal axis A. The hollow structure 10 may be, for example, in the form of a hollow cylinder. The cross-section of the hollow structure 10 may also be formed in a different way, for example rectangular, elliptical, or polygonal. The shown hollow structure 10 has an opening at one end, thus forming a water intake opening 3 through which water is able to flow into the channel 2 as indicated by arrows. The water intake opening 3 may be shaped to correspond to a specific outer contour of the hull of the vessel. An opposite end of the shown hollow structure 10 is closed by a wall 9, thus forming a recess in the hull of the vessel. The material of the hollow structure is typically metal or plastic material. The material may be steel or aluminium, for instance.
The manoeuvring system 1 further comprises a water nozzle 4 arranged within the channel 2. The water nozzle 4 is configured to guide or eject a water flow F through the water intake opening 3 at an angle α relative to the longitudinal axis A and in a plane perpendicular or substantially perpendicular to the Earth's normal. The angle α is typically in a range between 0°<α<90°, preferably in a range between 15°<α<75°, for example 30° or 45°. Typically, the water flow F is directed in a plane perpendicular to the Earth's normal. However, as the manoeuvring system 1 is in use fixedly attached to the hull of the vessel and the vessel is, i.a., susceptible to waves, current and unevenly distributed loading, the water flow F is often also directed in a plane substantially perpendicular to the Earth's normal. For example, rolling of the vessel caused by waves might lead to a situation where the water flow F is temporarily guided through the water intake opening 3 at an angle α relative to the longitudinal axis A and in a plane substantially perpendicular to the Earth's normal. An area of cross-section of the nozzle 4 is less than an area of cross-section of the channel 2. Consequently, water flows into the channel 2 at a lower speed than the water to be ejected through the water nozzle 4, thus resulting in avoiding or at least reducing cavitation in the system 1.
The manoeuvring system 1 furthermore comprises a piping 5 connected to the channel 2 at a first end 6 and connected to the water nozzle 4 at a second end 7. The nozzle 4 may also be formed by the second end 7 of the piping system 5. As can be seen, the piping 5 is partially arranged outside of the channel 2 and partially arranged within the channel 2. Alternatively, the nozzle 4 may be integrated into the hollow structure 10 such that the piping 5 is arranged completely outside of the channel 2. A material of the piping 5 is typically metal or plastic material. The material may be steel or aluminium, for instance. Preferably, the material of the hollow structure 10 and the piping 5 are identical in order to allow welding of the components for providing a watertight structure.
A pump 8 is arranged between the first end 6 and the second end 7. The pump 8 is configured to control, create and/or adjust the water flow F through the water nozzle 4. In other words, a pump 8 is provided for ejecting water through the water nozzle 4. The pump 8 is configured to be operated by a power source. The power source may be a battery, a generator or a solar panel, for instance. Typically, the power of the pump 8 can be tuned continuously in order to control a pressure and/or a mass flow through the water nozzle 4. The pump 8 may be configured to be primed continuously to reduce control response time. By priming the pump 8, keeping electric power on the pumps and/or the inflow and/or outflow of the fluid present in the pump 8 is meant. The pump 8 may be a centrifugal pump, for instance.

The manoeuvring system 1 comprises a hollow structure 10 forming a channel 2 having a longitudinal axis A. The hollow structure 10 may be, for example, in the form of a hollow cylinder. The cross-section of the hollow structure 10 may also be formed in a different way, for example rectangular, elliptical, or polygonal. The shown hollow structure 10 has a first opening at one end and a second opening at a second opposite end, thus forming a first water intake opening 3a and a second water intake opening 3b through which water is able to flow from both sides of the channel 2 into the channel 2 as indicated by arrows. The water intake openings 3a, 3b may be shaped to correspond to a specific outer contour of the hull of the vessel. The length of the hollow structure 10 typically corresponds to the width of the hull of the vessel at the installation position of the hollow structure 10. In other words, a channel 2 is provided below the water surface through the entire hull of the vessel from the starboard side of the vessel to the port side of the vessel.
The manoeuvring system 1 further comprises a first water nozzle 4a and a second water nozzle 4b arranged within the channel 2.

The second water nozzle 4b is configured to guide or eject a second water flow F2 through the second water intake opening 3b at an angle β relative to the longitudinal axis A and in a plane perpendicular or substantially perpendicular to the Earth's normal. The angles α and β are typically identical. The angles α and β are typically in a range between 0°<α, β<90°, preferably in a range between 15°<α, β<75°, for example 30° or 45°. Typically, the water flows F1, F2 are directed in a plane perpendicular to the Earth's normal. However, as the manoeuvring system 1 is in use fixedly attached to the hull of the vessel and the vessel is, i.a., susceptible to waves, current and unevenly distributed loading, the water flows F1, F2 are often also directed in a plane substantially perpendicular to the Earth's normal. For example, rolling of the vessel caused by waves might lead to a situation where the first water flow F1 and the second water flow F2 are temporarily guided through the water intake openings 3a, 3b at respective angles α, β relative to the longitudinal axis A and in a plane substantially perpendicular to the Earth's normal.
The manoeuvring system 1 furthermore comprises a first piping 5a connected to the channel 2 at a first end 6 and connected to the first water nozzle 4a at a second end 7.

As can be seen, the first piping 5a and the second piping 5b are each partially arranged outside of the channel 2 and partially arranged within the channel 2. Alternatively, the nozzles 4a, 4b may be integrated into the hollow structure 10 such that the first piping 5a and the second piping 5b are arranged completely outside of the channel 2. A material of the first piping 5a and the second piping 5b is typically metal or plastic material. The material may be steel or aluminium, for instance. Preferably, the material of the hollow structure 10 and the first piping 5a as well as the second piping 5b are identical in order to allow welding of the components for providing a watertight structure.
A first pump 8a is arranged between the first end 6 and the second end 7 of the first piping 5a. The first pump 8a is configured to control, create and/or adjust the first water flow F1 through the first water nozzle 4a. Similarly, the manoeuvring system 1 comprises a second piping 5b connected to the channel 2 at a first end 6 and connected to the second water nozzle 4a at a second end 7. A second pump 8b is arranged between the first end 6 and the second end 7 of the second piping 5b. The second pump 8b is configured to control, create and/or adjust the second water flow F2 through the second water nozzle 4b. In other words, pumps 8a, 8b are provided for ejecting water through the water nozzles 4a, 4b. The pumps 8a, 8b are configured to be operated by a power source. The power source may be a battery, a generator or a solar panel, for instance. Typically, the power of the pumps 8a, 8b can be tuned continuously in order to control a pressure and/or mass flow through the water nozzles 4a, 4b. The pumps 8a, 8b may be configured to be primed continuously to reduce control response time. By priming the pumps 8a, 8b, keeping electric power on the pumps and/or the inflow and/or outflow of the fluid present in the pumps 8a, 8b is meant. One pump 8a, 8b is provided for each respective water nozzle 4a, 4b. The pumps 8a, 8b may be each a centrifugal pump, for instance.

The above mentioned translational and/or rotational movements may also be controlled by a computing device or an artificial intelligence module. It is to be pointed out that above movements may further be assisted by a flow not mentioned in above bulleted list due to e.g. an external aerodynamic and/or hydrodynamic force exerted on the hull 12 of the vessel 11 and detected by a sensor. For example, when the vessel 11 moves forward by simultaneously controlling flows F1 and F2 and a wave hits against the bow from the starboard side, the flow F3 may be temporarily activated by the processing unit 15 in order to steer the vessel 11 in the forward direction, i.e. to compensate for the temporarily impact of the wave. At least one of the flows F1, F2, F3, F4 may further be activated based on at least one signal of at least one sensor comprised by the arrangement.

Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. In addition, various embodiments and example of the present invention may be referred to herein along with alternatives for the various components thereof. It is understood that such embodiments, examples, and alternatives are not to be construed as de facto equivalents of one another, but are to be considered as separate and autonomous representations of the present invention.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the description, numerous specific details are provided, such as examples of lengths, widths, shapes, etc., to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.
While the forgoing examples are illustrative of the principles of the present invention in one or more particular applications, it will be apparent to those of ordinary skill in the art that numerous modifications in form, usage and details of implementation can be made without the exercise of inventive faculty, and without departing from the principles and concepts of the invention. Accordingly, it is not intended that the invention be limited, except as by the claims set forth below.
The verbs “to comprise” and “to include” are used in this document as open limitations that neither exclude nor require the existence of also un-recited features. The features recited in depending claims are mutually freely combinable unless otherwise explicitly stated. Furthermore, it is to be understood that the use of “a” or “an”, that is, a singular form, throughout this document does not exclude a plurality.
At least some embodiments of the present invention find industrial application in equipping a vessel such as motor boat with an additional manoeuvring system.
