Definitions
- the present invention refers to a mooring system between a movable unit, e.g. ship and a stationary unit, e.g. a quay, and which system comprises partly a mooring device consis ⁇ ting of a robot arm movable in the vertical direction which arm is provided with coupling means at one of the units and partly a mooring armature for receiving and fixation of the coupling means at the other unit.
- the object of the present invention is to provide an active mooring device, which is structurally simple, which in principle consists of only one actuator, e.g. a hydraulic cylinder, which gives a possibility of a relatively long retracting distance. Further it has to be designed such that no bending moments are transmitted to the actuating device, on the ship side it should have a very small installation depth and there should be a possibility for mounting ex ⁇ ternally along the ship fender ledge. The device further should be designed such that it does not demand any greater precision at the landing and in passive position it should be protected inside the ship fender line of the quay.
- a actuating device which is movable in the hori ⁇ zontal direction (z-direction), preferably actuable during the whole mooring phase, and that a device is connected to the coupling means, for absorbing of lateral forces acting on the extreme free end of the actuating device (lateral ship forces), so that substantially no bending moments are transmitted to the actuating device, and that said device is ' constituted by bendable means, provided to act on the coup- ling means and which are intended to transmit said forces to either of the units or to both of the units.
- Fig.l shows in a diagrammatical view from the above of a ferry which has landed at a quay and is moored by means of the devices according to the present invention.
- Fig. 2a-2g shows in seven lateral views maneuvering sequen ⁇ ces at mooring of a ship, whereby fig. 2a shows the mooring. device in a protected position inside the ship fender line, fig. 2b during adjustment of the vertical position relative ⁇ ly the ship, respectively the water surface, fig. 2c shows the device during pushing out of the mooring cylinder, fig. 2d pivoting out of the mooring cylinder, fig. 2e position finding of the mooring armature at the ship, fig. 2f hauling of the ship by means of the mooring cylinder and fig. 2g the ship in mooring position.
- Fig. 3 shows in larger scale a first variant in a view from the front of a mooring device according to the invention.
- Fig. 4 shows a section along the line IV-IV in fig. 3.
- Fig. 5 shows a lateral view of the mooring device illustra ⁇ ted in fig. 3.
- Fig. 6 is a section along the line VI-VI in fig. 4.
- Fig. 7 shows the mooring armature illustrated in fig. 4 in a view from the front and partly in section.
- Fig. 8 shows a section along the line VIII-VIII in fig. 7.
- Fig. 9 shows in perspective view a second embodiment, of the mooring device according to the invention.
- Fig. 10 shows the mooring device according to fig. 9 in a view from the front.
- Fig. 11 is a section along the line XI-XI in fig. 10.
- Fig. 12 is a section along the line XII-XII in fig. 10
- Fig. 13 shows a section along the line XIII-XIII in fig. 12.
- Fig. 14 shows a view from the above of the mooring armature and the coupling means illustrated in fig. 13.
- fig. 1 is shown an embodiment of how the mooring device according to the invention can be used for mooring of two units 10,11, of which one can be a ship-, a ferry, a barge or some other floating object, while the other unit can be constituted by a quay, kevel head, an oil-rig or the like, that is a stationary plant.
- a type of mooring device 12 at the bow which is exposed only to small angular deviations and a mooring device 13 with a spring function at the stern of the ship.
- the ship - the railway ferry - is equipped with a movably mounted ferry flap 14 , which locks the ship at the quay in such a way, that it also absorbs longitudinal ship forces.
- a movably mounted ferry flap 14 which locks the ship at the quay in such a way, that it also absorbs longitudinal ship forces.
- only one mooring device 12 is required at the bow, which absorbes cross ship forces and smaller deviations from these, and a mooring device 13, which also can absorb longtudinal ship forces.
- the embodiment shown in figures 3-6 consists of a mooring device 15 provided at the stationary unit, that is the quay
- a robot arm 20 which in the embodiment shown is constituted by an actuator 21, e.g. a hydraulic cylinder, which is pivotably arranged on bearings such that it has at least two, at least three degrees of freedom, that is a large mobility in the vertical plane - the Y-axis .-, limited mobility in the vertical plane
- the robot, slider 19 which supports the robot arm 20, is by way of a wire, cable or chain arrangement 22 and pulleys 23 counter balanced by means of weights 24.
- a driving device 25, fig. 6 which acts on one of the pairs of pulleys 23, the elevation of the slider 19 can be changed.
- the robot arm is pivotable about its horizontal axis 26 by means of a second actuator 27, which as well can be a hyd ⁇ raulic piston cylinder.
- a coupling means 28 formed as a hook with a relatively large curved contact surface for a mooring armature 29 arranged at the second unit 10- the ship.
- this is constituted by .
- the connection means between the bendable means 30 and the tension springs 31 are formed with a guide 33, which coope ⁇ rates with a slot 34, which limits the extension length of the tension spring.
- the bendable means 30 takes a straight position, protected by the ship fender line or.shell plating, so that the hook-formed coup ⁇ ling means 28 can grip behind the wire, such as is shown in fig. 4.
- FIG. 2a shows the moo ⁇ ring device with the robot arm folded up to a protected position inside the outer edge of the quay, which normally is a fender arrangement not shown.
- the mooring device 15 is manipulated by means of radio signals whereby as a first measure an adjustment is carried out of the elevation of the robot arm.
- This eleva ⁇ tion adjustment can be performed either against one or several direction marks at the shell plate of the ship or with reference to the present water surface.
- This sequence is shown in fig. 2b.
- a second embodiment of the invention is shown in fig. 9, which in many parts are similar to the embodiment according to figures 3-8 and for those parts which are alike in both embodiments the same reference designations also have been used. What differs both embodiments is the mooring device according to fig. 9 being completed with a spring function and that the robot arm 20 is movable in the horizontal plane For this purpose are provided linear guides 35 at the sta ⁇ tionary unit 11, along which guides a slider 49 is displace- able.
- the spring function of the mooring device is provided by stays 36 directed in opposite directions and articulatedly joined to the coupling means 28 of the robot arm 20, which stays at their opposite ends are connected each to a hydrau- lie power apparatus 37 by a pulley 38.
- the cylinders of the robot arms are dimensioned to absorb the forces transverse of the centerline of the ship and the spring absorbs the longitudinal and the cross ship forces.
- the mooring armature 29 on the movable unit 10 in fig. 9 is constituted by a kevel head 40 and the coupling means 28 of the robot arm 20 thus is formed as a ring 39, which kan be thread over the kevel head 40.
- the hydraulic power apparatu ⁇ ses 37 can also be used to position the robot arm before a mooring, whereby the robot slider 19 is vertically displace- able along a guide 18 contained in a slider 49, which in turn is movable along guides 35 fixedly mounted at the quay 11 ,
- the horizontal displacement of the slider 49 along the guides 35 is carried out by means of the power apparatuses 37, whereby between the stays 36 and the robot slider 19 are provided interconnection links 50, which transmit the tensi ⁇ le forces to the slider 49.
- the unit 10 has been stated to be the movable unit, that is a ship, a ferry a barge or the like, while the stationary unit can be a quay, an oil-rig or the like, but of course it is possible to place the mooring device on the movable unit and the mooring armature on the stationary device.
