    TITLE Mooring device TECHNICAL FIELDThe present invention relates to a Mooring device for boats, ships and vessels.
    BACKGROUND ART Traditionally mooring devices are located on high decks and short berths,which leads to in effective rope angles that are not always able to ensure thatvessels are reliably moored to the quay.
    External forces caused by passing ships, wind, suction and swell arecomplex and vary continually. lf the vessel moves sideways in its berth, rampand gangway positioning become unsafe.
    Commonly hydraulic mooring device are used to moor ships, said mooringdevices can adjust the force in the mooring cable dependent of the varyingexternal forces, i.e. slack the mooring cable when the force on the mooringcable exceeds a force threshold and haul in the cable when the force on themooring cable decreases. There are active and passive systems on themarket, the active systems are continuously powered in order to achieve theslacking and tensioning of the mooring cable. ln WO 2010 110 666 is apassive hydraulic mooring device disclosed, which uses valves that open andcloses in order to achieve the slacking and tensioning of the mooring cable.
    Disadvantageous with the hydraulic devices in general are that they areexpensive and sensitive to leakages. Further hydraulic devices can be anenvironmental problem due to the leakages of hydraulic fluids.
    Electric mooring devices are known, in which an electric winch hauls the mooring cable on a drum. There are solutions to slack the mooring cable passively, but the winch must be turned on in order to haul the mooring cable backin.
    Hence, there is a need for a mooring device that allows an adjustment of theforce on the mooring cable, is versatile in respect of placement andpowering, is safe and environmental friendly and is able to withstand the varying external forces a moored vessel can be exposed to.
    SUMMARY Among others the object of the present invention is to provide an inventivemooring device for boats and ships. lt is desired that the inventive mooringdevice is independent of the power source, and has low power consumption,and has the ability to compensate for variations of the external forces. The inventive mooring device is defined in claim 1.
    The invention is based upon the idea that the tension in the mooring cablecan be secured by a resilient member instead of an actuator, whereby the tension in the mooring cable can be upheld without any energy is consumed.
    The mooring device according to the invention comprises an arm, an actuator, quay anchoring means, and at least one resilient member.
    Said arm having a first and a second end, wherein said first end is adapted tobe coupled in series with a mooring cable of a ship. The first end is therebyprovided with a mooring cable attachment point, such as a through hole or ahook, any attachment other point suitable for a mooring cable is however imaginable.
    Said actuator is adapted to act on said arm, such that the arm thereby extractor retracts. By retracting the arm a mooring cable attached to saidattachment point can be pulled in, or a pulling force can be applied thereon.Said actuator is preferably any kind of conventional electric motor, for example provided with a worm gear converting the rotational movement ofthe electric motor to a translational movement of the arm. An electric actuatorhas several advantages; it is easy to maintain and has a high efficiency, ifneeded, the electric actuator is easy to replace and can be connectedanywhere there are an electric connection. Further, an electric actuator alsohas environmental advantages, since it has a silent run and it does not haveany exhaust gases or fluids dripping from it. However, if desirable theinventive mooring device can also be run by hydraulic, pneumatic actuator or even a combustion driven actuator.
    Said quay anchoring means is adapted to secure the inventive mooringdevice to the quay, at least in the direction of the ship that is to be moored.The quay anchoring means can be a loop of wire, a hook or some otherarrangement suitable to attach the mooring device to a pollard or similar onthe quay. However, since the inventive mooring device can be used forsmaller boats as well for larger vessels, the quay anchoring means as well asother parts of the mooring device must be adapted to the expected loads of the ship to be moored.
    The inventive mooring device is characterised in, that at least one resilientmember is arranged between the arm and said quay anchoring means. Theresilient member is arranged in the course of force such, that it iscompressed when a pulling force on the first end of the arm, is met by areaction force on the quay anchoring means. The pulling force is directed inthe direction of the arm and in a direction away from said second end.
    Said resilient member arranged in the course of force between the secondend of the arm and the quay anchoring means will be compressed when aship is moored with the inventive mooring device. The compressed resilientmember will thereby exercise a load on the mooring cable, which load isdependent of the resilient characteristics of the resilient member and themooring force applied on the mooring cable. Due to the resilient member a variable pretension in the mooring cable can be applied. The resilientmember is able be more compressed if the mooring cable is exposed to anincreased pulling force, for example caused by off or on shore winds. Thecompression of the resilient member assures a longer endurance of theresilient member than if the resilient member would be exposed to tractiveforces. Further, the resilient member keeps a tension in the mooring cablewhen the force in the cable, for example when the moored vessel is exposed to onshore winds.
    The desired compression of the resilient member is dependent of theproperties of the resilient member, wherein the mooring device and itsresilient member obviously are adapted to the size of the moored ship/vessel.The desired compression is thereby dependent of the desired tension in the mooring cable. lt is preferred that the resilient member is provided with a hollow interior suchthat said arm can be arranged through said hollow interior.
    The resilient member has a first and a second end. Said first end issupported against said actuator, wherein the resilient member extends fromthe actuator such that its second end is arranged in the direction of the firstend of the arm. The quay anchoring means is thereby attached to the secondend of the resilient member. When a pulling force is applied on the arm of ananchored mooring device, said pulling force will compress the resilientmember between the quay anchoring means and the actuator, thereby is thefirst end of the resilient member displaced towards the resilient memberssecond end, which position, in the direction of the pulling force, is uninfluenced relative the quay anchoring means.
    By arranging the resilient member such that it extends from the second endof the arm in direction towards the first end of the arm, a compact design of the mooring device is achieved, because parts of the anchoring means andthe resilient member is able to run physically parallel with each other.
    There are different ways to achieve a desired characteristic of the resilientmember. A preferred way is that the resilient member comprises a plurality ofresilient components which are arranged in series to each other and saidresilient components having different resilient characteristics. ln such anarrangement the resilient component with the Iowest resistant will becompressed first and the resilient component with the higher resistant will becompressed thereafter. The resilient component with the higher resilientproperties will then be the one that adjusting the tension force in the mooringcable, wherein a smaller movement is achieved with a force with the same dimension.
    There are several different suitable designs of a resilient member for theinventive mooring device. A preferred resilient member however, is a cone ora cylindrical member in a material with resilient properties, such as a rubberor polymeric cone. Other possible resilient members are a helical spring. Theresilient members should however be arranged in the mooring device suchthat the resilient member compresses, since they thereby can be exposed tohigher forces, without being fatigued. A combination of a cone or a cylindricalmember and a helical spring is advantageous to create a resilient member with desired resilient characteristics.
    Further if a mooring device with a resilient member with stiffer properties is desired, the resilient member can comprise two or more resilientcomponents, which are arranged parallel with each other. Whereby, parallelarranged resilient components should have the same resilient properties, for balance reasons. ln addition a mooring device having a plurality of parallel arranged resilientcomponents could also be provided with a plurality of parallel arms, wherein each arm correspond to one resilient member and having corresponding actuator acting thereon. lt is preferable that said arm is a telescopic arm, thereby is a more compactmooring device achieved. Thereby acts the actuator preferably directly uponthe second end of the telescopic arm such that the first end retracts. ln an advantageous embodiment of the inventive mooring device saidactuator means is arranged on said second end of said arm and said resilientmember is arranged in the course of force between said actuator means andsaid quay anchoring means. By arranging the actuator at the second end ofthe arm, the length of the arm is used in full, whereby the mooring device iskept compact.
    Further, the resilient member is provided with a front plate provided at itssecond end, wherein the front plate is provided with an opening, throughwhich said arm is arranged. By providing a front plate at the second end ofthe resilient member, an attachment point for the anchoring means isfacilitated. Further, the opening in the front plate enables that the arm can bearranged there through and enabling the previous mentioned parallel arrangement of the arm relative the resilient member.
    The resilient member can further be provided with a back plate on its firstend, wherein said back plate supports said resilient member against saidactuator. The back plate is adapted such that it gives support to the resilient member, such that it can be supported by the actuator.
    Preferably, the quay anchoring means is provided with or connected to saidresilient member over a pivot joint, such that the quay anchoring means canpivot about said joint. The mooring device can thereby adjust its angle to theship/vessel that it is moored, wherein the pulling force from the mooring cableis optimally transferred to the telescopic arm and the mooring device.
    Thereby is the inventive mooring device able to keep the optimal angle evenduring movements of the ship/vessel caused by changed position in thewater, for example through load or unloading of the ship/vessel and/or WGVGS. lt is preferred that the actuator or the arm is provided with a self lockingmechanism, such that when a desired compression of said resilient memberis achieved the actuator is turned off and the arm is locked in its momentaryposition. By turning off the actuator and letting the resilient member adjust the load in the mooring cable, energy is saved.
    To avoid braking the mooring device if it is exposed to loads exceeding whatit is dimensioned for, the mooring device is supplied with a releasemechanism, which releases the mooring cable from the attachment pointmeans, if the load applied on the mooring device exceeds a predeterminedthreshold value. The release mechanism could be a braking mechanism suchas a brake bolt or pin or a mechanism that is can be reattached after it hasreleased. Due to the release mechanism, the moorings device is protectedagainst overload.

    DETAILED DESCRIPTION ln the following only different embodiments of the invention are shown anddescribed, simply by way of illustration of different modes of carrying out theinvention. Variations of the embodiments are not restricted to the specificshown embodiment, but are applicable on other variations of the invention.Corresponding parts in the different embodiments has been provided with the same reference numbers in the figures.
    Figure 1 a and b shows principle drawings of two different implementations of3 two different embodiments of the mooring device 1 is showed in more detail, the showed the inventive moorings system 1. ln figures 2 and embodiments corresponds the principle drawing shown in figure 1 a and in figure 4 is a working principle of the embodiments shown in figure 3 shown.
    The inventive mooring device 1 comprises an arm 2, an actuator 3, a quayanchoring means 4 and a resilient member 10. The main difference betweenthe two different implementations in figure 1 a and b is the arrangement ofthe resilient member 10.
    The resilient member 10 is arranged such that it is compressed when themooring device 1 is subjected to a pulling force F and a reaction force P.When the resilient member 10 is compressed it exposes the mooring cable 8for a traction force and thereby guarantees that the mooring cable 8 always issubjected to a tension. The capability range of the mooring device 1 isdependent of the dimensions of the resilient member 10, which as the rest ofthe mooring device 1 is customised to the size of the ship/vessel to be moored. The inventive mooring device 1 is suitable for small boats as well aslarge ships and vessels, as long as it is dimensioned for the craft in question.
    The mooring device 1 is provided with an arm 2 which is moveable in itslength direction, such that it can extract and retract. The arm 2 is preferably atelescopic arm, whereby the same retraction and extraction length can beachieved with smaller space demand.
    Said arm 2 having a first and a second end 5, 6, wherein said first end 5 isadapted to be coupled in series with a mooring cable 8 of a ship. Byretracting the arm 2 a mooring cable 8, attached to its first end 11, istensioned. By extracting the arm 2, said mooring cable 8 is loosened. ln the embodiment shown in figure 1a, the resilient member 10 is arranged atthe first end 5 of the arm, wherein the mooring cable 8 is attached to amooring cable attachment point 7 of the resilient member 10. ln the embodiment shown in figure 1b, the resilient member 10 is arranged as a part of the quay anchoring means 4. ln the embodiment, shown in figure 1a, the resilient member 10 is arrangedbetween the quay anchoring means 4 and actuator 3 and physically parallelwith the arm 2 but still in series in the sense of the course of force through the mooring device 1.
    Now the embodiment shown in figure 2 a and b will be described in further detailed.
    The embodiment of the mooring device 1 is compact, due to the parallelextension of the telescopic arm 2 and the resilient member 10. Thetelescopic arm 2 is provided with an actuator 3 arranged at its second end 6.Said actuator 3 is adapted to act on the arm 2, such that the arm 2 thereby extract or retracts. The actuator 3 is preferably any kind of conventionalelectric actuator 3 provided with a worm gear converting the rotationalmovement of the electric actuator to a translational movement of the arm 2.The mooring device 1 provided with an electric actuator 3, is among others easy to maintain, has a high efficiency and is silent running.
    The quay anchoring means 4 is adapted to secure the inventive mooringdevice 1 to the quay, at least in the direction of the ship that is to be moored.The quay anchoring means 4 is a loop of wire provided with an additionalstructure 19, which is attached to the resilient member 10. The quayanchoring means 4 can however be designed differently without deviating from the inventive idea.
    The resilient member 10 is a hollow rubber cone having a first and a secondend 11, 12, wherein the first end 11 is attached to the actuator 3 and thesecond end 12 is attached to the quay anchoring means 4 over the additionalstructure 19 and a front plate 13. The front plate 13 is thereby mounted onthe second end 12 of the resilient member 10. By arranging the arm 2through the hollow resilient member 10 a compact design of the inventivemooring device 1 is achieved. The arm 2 is connected to the actuator 3 and aback plate 20 arranged on the first end 11 of the resilient member 10. Thearrangement with the quay anchoring means 4 arranged to the second end12 of the resilient member 10 and thereby closest to the first end 5 of thetelescopic arm 2 and the actuator 3 arranged at the first end 11 of theresilient member 10 and the second end 6 of the telescopic arm 2, enablesthe compression of the resilient member 10, when the mooring device 1 issubjected to a pulling force F met by a reaction force R.
    Figure 3 a and b discloses two different embodiments of the inventivemooring device 1. Both embodiments uses a resilient member 10 with twoserial coupled resilient components 111, 112, wherein the embodimentshown in figure 3a one mooring device 1 (figure 3a) is used. ln the 11 embodiment shown in figure 3b two mooring devices are partially parallelcoupled, i.e. some parts are shared between the two. ln the embodimentshown in figures 3b the two arms 2 are provided with a common attachmentplate 7 to which the mooring cable 8 can be attached. Both mooring devices1 are adapted to be mounted in a seating 30, shown in figure 3c, wherein thedimensions of the seating, has to be adapted to the dimensions of the mooring device 1.
    Using two parallel coupled mooring devices and thereby also two parallelcoupled resilient members 10, increases the maximum load of the mooringdevice 1. Such a mooring device 1 is thereby suitable for larger ships. Theworking principle of the two embodiments are however the same and isdescribed further below in conjunction with figure 4.
    Since the principle structure of the two embodiments shown in figure 3 arethe same, the two embodiments will be described primarily in conjunctionwith figure 3a.
    The mooring device 1 is adapted to be seated in the seating 30, wherein thepivot joints 15, 16 are arranged there between. The quay anchoring means 4is fixedly attached to support bars 29. Said support bars 29 acts as a framefor the mooring device 1 and stabilises the construction. Towards the supportbars 29 ends that are closest to the first end 5 of the arm 4, the support bars29 are fixedly attached to the front plate 1. Hence, the quay anchoring means4 is fixedly connected to the front plate 13, and thereby to the second end 12 of the resilient member 10.
    A back plate 20 is arranged at the other end of the support bars 29. The backplate 20 is arranged such on the support bars 29 that it can slide thereon.The first end 11 of the resilient member 10 is supported against one side theback plate 20 and the actuator 3 is provided on the other. The support bars 12 29 are provided with check bolts 31 defining an end position of the back plate20.
    An intermediate plate 28 is arranged in between the front and the back plate13, 20. The intermediate plate 28 separates the first resilient component 111from the second resilient component 112. The intermediate plate 28 isarranged such on the support bars 29 that it can slide thereon. ln theembodiment shown, the intermediate plate 28 is arranged between the quayanchoring means 4 and the back plate 13; however the intermediate plate 28 could optionally be arranged on the other side of the back plate 13.
    The arm 2 is a telescopic arm, and is arranged such that it passes throughopenings 32 in quay anchoring means 4. The front, intermediate and backplate 20, 13, 28 are also provided with corresponding openings 13, 33, 36.The resilient member 10 passes however just through the openings 32 in thequay anchoring means 4.
    An attachment point 7 for a mooring cable 8 is arranged at the first end 5 ofthe arm 2. ln the embodiment shown in figure 3b, the attachment point 7 isshared by the two arms 2. ln the embodiments shown in figure 3a and 3b the first resilient component111 is a helical spring and the second resilient component 112 is a cylinderof a resilient material, such as rubber. The two resilient components 111, 112are connected through the intermediate plate 32. The type of resilientmembers shown should be seen as examples and the invention is not limitedthereto. However hollow resilient components 111, 112 are preferred toenable the arm 2 to pass through them.
    The mooring device 1 is mounted in the seating 30, wherein the mooringdevice 1 is connected to the seating 30 over the pivot joints 15, 16 and theseating is secured to the quay, for example at a pollard (not shown). The 13 quay anchoring means 4 of the mooring device 1 is preferably arranged,such that the mooring device 1 has its centre of gravity such that the mooring device is in balance in the seating 30, when the mooring device 1 is at rest. ln the embodiments of the invention shown in figure 3a and b, the resi|ientmember 10 comprises a first and a second resi|ient component 111, 112.This is to provide the resi|ient member 10 with the resi|ient characteristicsneeded in a low cost manner. The resi|ient member 10 should have a firstcompression phase, at which it has a lower elastic reaction and a secondcompression phase, at which it has a higher elastic reaction. The easiest wayto achieve this is with a resi|ient member 10 with two resi|ient components 111, 112, as in the embodiments shown in fig. 3a and b.
    Now the function the embodiments of a mooring device 1 shown in figure 3ais explained in conjunction with figure 4 a to e. The mooring device 1 in thefigures 4 a to e is the embodiment of a mooring device 1 shown in figure 3a or b seen from a side view. ln the figures 4a and b the mooring device 1 is shown in an unloaded stateand with fully extracted arm 2. ln figure 4a is the mooring device 1 shown inits seating 30, which is hold by a pollard 35, which pollard 35 is arranged ona quay 34. The seating 30, the quay 34 and the pollard 35 is not shown in thefigure 4 b-c for reasons of simplicity. ln figure 4c, the actuator 3 has interacted with the arm 2, such that the arm 2has retracted and wherein the mooring cable 8 attached at the first end 5 ofthe arm 2 has become tensioned. A force F thereby acts upon the arm 2. Theforce F is met by a force of reaction R upon the quay anchoring means 4, i.e.where the mooring device 1 is attached to the quay. ln this position, a compression of the resi|ient member 10 has still not occurred. 14 ln figure 4d, the actuator 3 has increased the tension in the mooring cable 8,by retracting the arm 2 further. The resilient member 10 is therebycompressed, wherein first resilient component 111, which is provided with thelowest elastic reaction is compressed a distance c1, which is significant morethan the second resilient component 112, which is provided the higher elasticreaction and which is compressed a distance k1. Depending on how theresilient characteristics of the resilient components 111, 112 are chosen,different compression ratios between the two resilient components 111, 112are available. The shown configuration is however beneficial, because thehysteresis properties of the rubber in the second resilient component 112makes it suitable as a damping component. The first resilient component 111enables the pre-tension of the mooring cable 8, whereby the second resilientcomponent 112 mainly functions as a damping element. The compression ismade possible, since the back plate 20 and the intermediate plate 28 isslidable attached to the support bars 29. As can be seen in the figures, theactuator 3 thereby follows the back plate 20, upon which the actuator 3 is mounted. ln the position shown in figure 4d, the mooring device 1 is locked. The arm 2has reached its end position whereby the actuator 3 cannot retract the armany further. The actuator 2 can thereby be shut off, and the mooring device 1thereby holds this position. A slack in the mooring cable 8 is prevented in thatthe resilient member 10 pushes the back plate 20 and thereby also the arm 2and the actuator 3 away from the mooring cable 3, i.e. to the left in the figure4. ln a situation where a force acts upon a ship moored, such that the ship ispressed away from the quay, the force F acting on the arm 2 will increase,wherein the first end 8 of the arm will be pulled further away from the frontplate 13 and the quay anchoring means 4, this is enabled through anadditional 10. The additional compression comprises of a compression c2 of the first resilient component compression of the resilient member 111 and a second compression k2 of the second resilient component 112.Whereby the compression c2 is smaller than the second compression k2,since the first resilient component 111 almost already were fully compressed.The distance r2 the arm can be pulled out when the mooring device 1 is in itslocked state equals the added compression c2, k2 of the first and the secondresilient component 111, 112 caused by the increased force F acting on the arm 2. lf the force F increases even more, when the resilient member 10 already isfully compressed, a release mechanism can be arranged at the attachmentpoint 7 for the mooring cable 8, wherein the release mechanism releases themooring cable 8 before the load on the mooring device 1 becomes too high.
    The inventive mooring device 1 provides a simple construction, which haslow energy consumption due to its passive adaption to a varying load on thedevice. This is achieved through the inventive arrangement of the resilientmember 10. The actuator 3 must only work in order to retract or extract the arm 2.
    Reference signs mentioned in the claims should not be seen as limiting theextent of the matter protected by the claims, and their sole function is to make claims easier to understand.
    As will be realised, the invention is capable of modification in various obviousrespects, all without departing from the scope of the appended claims.Accordingly, the drawings and the description thereto are to be regarded asillustrative in nature, and not restrictive.
