Ship mooring equipment

Abstract

There was a demand for mooring equipment for ships that would eliminate the need for workers on the quay side. This would address the aging population of island residents and ensure shipping routes to remote islands. [Solution] A telescopic boom is installed on the hull, and a guide rope is suspended from the tip of the boom. An expanding member positioned at the lower end of the guide rope expands and holds the loop at the end of the mooring rope, allowing it to descend from above onto the mooring post on the quay. The loop at the end of the mooring rope is fitted onto the mooring post. Pulling the mooring rope completes the mooring operation. The process is reversed when departing. For example, the expanding member connects two opposing points of the loop, and this is lifted by the guide rope to remove the loop from the mooring post. These operations are performed by a worker on the hull using a remote control while viewing camera footage fixed to the tip of the boom.

Problems to be Solved by the Invention

[0004] However, recently, the shortage of workers on remote islands and the like has presented a serious situation, and in particular, the survival of the route itself has been at risk in the operation of small passenger ships and small passenger ferries. As a result, regarding mooring to a quay wall (including a pier), unmanned operation on the quay wall side has been desired.

[0005] As a result of diligent research, the inventor discovered that all of the above problems could be solved by controlling the raising and lowering of the suspended guide rope, for example using a camera monitor. This was achieved by suspending and holding the loop-shaped end of the mooring rope in an expanded state, releasing the expanded state when the loop-shaped end touches the ground to enable mooring to a mooring post (also known as a bollard or bit), and conversely, expanding the loop-shaped end to release it from the mooring post. Thus, the inventor completed this invention. In other words, this invention relates to the loop-shaped part at the end of a mooring rope. To the mooring post The purpose of this system is to eliminate the need for work on the quay (pier) side by allowing attachment and detachment to be done only from the hull side, thereby securing shipping routes to remote islands where there are no workers. [Means for solving the problem]

[0006] The invention described in claim 1 is a telescopic boom provided on the hull of a ship, which is rotatable in the horizontal plane and extendable in the longitudinal direction thereof, and which can be extended and retracted. the above A mooring rope provided on the hull and having an expandable loop at its tip, the above Rewinding from the tip of the telescopic boom 、 Suspended in a retractable manner 、 A guide rope is provided at the lower end to hold the ring-shaped portion, and at the lower end of this guide rope, By winding and unwinding the guide rope, upper position It is possible to determine the landing position. Expanding member and The expanding member comprises a plurality of guide pieces, the upper ends of which are connected to the guide rope, and the lower ends of which are locked to multiple opposing positions on the ring-shaped portion, thereby expanding and holding the ring-shaped portion when the expanding member is in the upper position, and releasing the expanded state of the ring-shaped portion by winding up the mooring rope when the expanding member has descended from the upper position to the landing position. It is a mooring device for ships.

[0007] For example, a support column (post) of a predetermined height is erected on the bow deck of the ship's hull, and a horizontal telescopic boom is supported at the top of the column so as to be able to rotate horizontally. The base end of the telescopic boom is supported by the support column and is configured to extend and retract along its length. A guide rope is suspended from the tip of the telescopic boom. The guide rope is retractable and unwindable, and its tip is able to move up and down. The lower end of the suspended guide rope is suspended from the eye splice at the end of a mooring rope, which is expanded to form a nearly circular, horizontal shape. The mooring lines are designed to be easily retracted and retracted using winding machines positioned and fixed to the deck. The loop-shaped end of the mooring line is held in a nearly circular shape by a guide line when viewed from above. An expanding member is provided at the lower end of the guide line. This expanding member is for expanding Guide piece (metal piece), etc. It is composed of the above, and the ring-shaped part is held in a circular shape of a predetermined diameter in the upper position. When the guide piece touches the ground (when it has descended to the landing position) For example, when the ship lands with the ring-shaped part surrounding the mooring post. 、 The expanded state means that it will be released. When the mooring line is wound up by the winding machine while the mooring line is on the ground, the ring-shaped section is pulled from the constricted part and deforms into an oval shape, thereby securely fastening the mooring line to the mooring post (such as a hook-shaped bit). To remove the ring-shaped section from the mooring post, loosening the winding machine and raising the guide line causes the expanding member to expand the ring-shaped section into a circular shape as it rises and detaches from the mooring post. The hull can then leave the dock.

[0008] The expanding member expands the loop portion of the mooring rope to form a circle (opening) of its maximum diameter when suspended by the guide rope. For this purpose, two intersection points (both ends in the diametrical direction of the loop portion) at a diameter perpendicular to the diameter connecting the constricted end (winding side end) and the tip of the loop portion are provided for the expansion. With a guide piece It is desirable to tie each to a guide cable. The guide cable extends vertically to the center of the line connecting these two intersection points, and its lower end is Guide piece It is connected to the upper end. It is important that this ring-shaped section maintains its maximum diameter, a circular opening, when suspended, and is held horizontally. Therefore, an expanding member is configured for these purposes. This is a pair of expanding members. The guide piece is Same length preferable. Alternatively, a pair of guide pieces are expanded by a ring (cylindrical metal fitting) with a smaller diameter than the opening of the ring-shaped section (forming an isosceles triangle when viewed from the front), with their lower ends connected to the ring-shaped section and their upper ends connected to the guide cable. These guide pieces have a slanted shape that widens at the bottom, suspending the ring-shaped section in an expanded and horizontal state. The guide pieces can consist of two pieces at the diameter position and two more pieces, for a total of four pieces. All four of these guide pieces are arranged at equal intervals on the constricted end side of the circular ring-shaped section. In other words, the ring-shaped section, which is expanded by the expanding member to maintain its circular shape, is pulled toward its constricted end side by the winding machine when it touches the ground as the guide rope descends, and takes on an oval shape. At this time, the connecting part is provided on the constricted side of the ring (eye) to prevent the suspended expanding guide pieces from hitting and being damaged by mooring posts or the like. When forming a ring-shaped section with four guide pieces, the connection points between these four pieces and the ring-shaped section are symmetrical (in the tensile direction). Furthermore, they are connected and positioned only on the semicircular section on the aperture side. Also, when the four guide pieces are suspended... 、 Each of the four guide pieces and the metal ring, which constitute the expanding member, are pin-connected by a ring at a position above the halfway point along its length. As a result, the four guide pieces and the metal ring are held by the guide cable so that these guide pieces open downwards (maximum expansion of the ring-shaped portion). In short, when expanding the loop at the end of a mooring rope to maintain its circular shape, the expansion guide piece has its lower end connection at two positions that are 180 degrees apart from the circle when viewed from above, and that are perpendicular to the winding direction (the direction in which the mooring rope extends). This is intended to avoid obstructing the view when confirming the position of the mooring post using images taken by a camera mounted on the boom tip (the end from which the guide rope is suspended), to avoid causing any obstacles or resistance during winding, and to prevent damage during winding.

[0009] The invention described in claim 2 is, The multiple guide pieces described above are pivotably mounted on a horizontal pin at a position above the midpoint of their length, and these pins are fixed to a cylindrical ring. The expanding member holds the ring-shaped portion in an expanded state when it is in its upper position, and when the expanding member descends to the landing position, the mooring rope is wound up to release the expanded state of the ring-shaped portion. The mooring device for a ship as described in claim 1. The telescopic boom and other components are driven (operated) by a crew member on the ship using an operating device. In this case, a camera that captures images of the area below is positioned at the tip of the telescopic boom. The lower end of the guide rope is captured in a plan view, and the crew member on board confirms this on the monitor of the operating device. When the guide rope, which is the tip of the boom, is positioned directly above the mooring post (quay), the guide rope is lowered (up and down operation), and the ring-shaped part is operated and lowered so that the mooring post is surrounded by the ring-shaped part (so that the entire mooring post is positioned inside the ring of the ring-shaped part). Once the descent is complete (the ring-shaped section touches the ground), the mooring rope is wound up by a winding mechanism on the hull, and the ring-shaped section is extended through the mooring rope until it becomes an oval shape, completing the mooring operation. At this time, the tip of the telescopic boom, the guide rope, is held directly above the mooring post. Operators can perform mooring and detachment operations using a control system (control panel or actuator) that includes a monitor.

[0010] The above-mentioned expanding member is, It has multiple guide pieces, and the upper ends of these guide pieces are as described above Connected to the guide rope The lower end of the ring-shaped portion is locked to multiple opposing positions on the ring-shaped portion. It is being expanded. The metal pieces (guide pieces), which are expanding members positioned at the lower end of the guide rope, consist of a pair. The lower end of one guide piece is attached to a part of the circumference of the ring-shaped section at the tip of the mooring rope, and the lower end of the other guide piece is attached to the opposite position in the circumference of this ring-shaped section (approximately 180 degrees apart). When these guide pieces are suspended from the guide rope, their lower ends are held apart by a predetermined distance (the diameter of the ring-shaped section), thereby expanding the ring-shaped section into a circular shape and holding it horizontally.

[0011] Claim 3 The invention described is The above-mentioned guide cable is loosely inserted into a guide pipe hanging down from the tip of the telescopic boom, as described in claim 2. It is a mooring device for ships. This guide pipe protects the internal guide rope and prevents it from swaying unstably due to the ship's movement, wind, etc. The guide pipe can also be made to move up and down freely with the winding and unwinding of the guide rope. It is preferable to form the guide pipe from a transparent material to reduce weight and ensure a clear field of view for camera imaging.

[0012] Regarding the ship mooring device according to the present invention, mooring work and unmooring work can be performed using, for example, a remote controller. That is, the operation of this device can be remotely controlled by one crew member of the device and the mooring machine on the hull deck. When the ship enters the port, the remote controller of this device is operated to swing the telescopic arm toward the quay side (holding the ring-shaped part at the tip of the mooring rope through the guide rope at the lower part and the spread hardware at the lower part thereof) and extend it in the quay direction. After the ship stops, while looking at the screen of the operation remote controller, the telescopic and swinging of the telescopic arm are operated by operating the lever of the operation remote controller to align the positions of the mooring post on the quay and the ring-shaped part at the tip of the mooring rope. Further, the guide rope is lowered in this state. As a result, the ring-shaped part at the tip of the mooring rope suspended by the guide rope lands on the quay, and the mooring rope and the mooring post are fastened. Mooring is completed by winding up the mooring rope with the mooring machine on the ship. On the other hand, to remove the mooring rope, loosen the mooring rope. That is, pay out the mooring rope with the mooring machine. Then, the tip of the mooring rope is deformed into a ring shape and can be pulled out from the mooring post. After pulling out, the mooring rope is wound up with the mooring machine, the device is swung, the telescopic arm is retracted, and this is stored to complete. Note that the ring shape at the tip of the mooring rope is in a ring shape when the mooring rope is hanging in the air, and is deformed into an oval shape by winding up the mooring rope of the mooring machine when it is on the quay and has a shape that does not come off the mooring post.

Effect of the Invention

[0013] Claim 1 ~3 According to the invention described in claim 1, the mooring work and the release work of the ferry at a ferry terminal or the like where there is no operator on the quay side can be performed by the operator on the hull side alone. For example, while confirming the position of the hardware (ring-shaped part) at the tip of the boom with a camera, the work of suspending and lifting the ring-shaped part of the mooring rope from the hull side can be surely and speedily performed. Furthermore, the ring-shaped section is expanded by the expanding member to maintain its circular shape, and when the guide rope descends and the ring-shaped section touches the ground, it is pulled towards its constricted end by the winding machine, taking on an oval shape. At this time, the connecting portion is provided on the constricted side of the ring to prevent the suspended expanding metal piece from contacting and damaging the bit. When the ring-shaped section is formed with four metal pieces, the connecting portions of these four pieces to the ring-shaped section are symmetrical (with respect to the axis of tension) and are connected and positioned only on the semicircular portion on the constricted side. In short, when expanding the ring-shaped section to maintain its circular shape, the expansion metal pieces are positioned at two locations 180 degrees apart from the circle in a plan view, and perpendicular to the winding direction. This is intended to avoid obstructing the field of view for confirming the bit position during imaging with a camera, to avoid causing obstacles or resistance during winding, and to prevent damage during winding. In other words, This system has the potential to offer additional advantages, such as improved work efficiency through a clear camera field of view, prevention of damage to extension hardware, and not interfering with winding operations. Claim 3 In addition to the above-mentioned effects, the invention described above allows for reliable and rapid mooring operations without being hindered by wind, rocking, etc. It can also be used at night, at dusk, and in windy and rainy conditions.

[0014] Claim 1~Claim 3 According to the invention described, it is possible to maintain shipping routes to remote islands with few inhabitants and no workers. Furthermore, it becomes possible for women and children with no experience as workers to help with the work. [Brief explanation of the drawing]

[0016] Hereinafter, embodiments of the ship mooring device according to this invention will be specifically described with reference to the drawings. [Examples]

[0017] The first embodiment of the present invention, a ship mooring device, will be described below with reference to Figures 1 to 4.

[0018] In other words, the mooring device for small vessels to an unmanned quay is configured to include a telescopic boom 13 positioned on the hull side as shown in Figures 1 and 2, and a winding machine 17 for the mooring rope 15, also located on the hull side. The device is also configured to include an expanding metal piece as an expanding member 21, as shown in Figures 3(a)(b) and 4(a)(b).

[0019] As shown in Figures 1 and 2, the ship's mooring device has a telescopic boom 13 of a predetermined length, which is mounted on the deck 11 at the bow of the hull and is rotatable in the horizontal plane. This telescopic boom 13 has a structure that allows it to extend and retract in its longitudinal direction. 31 is a telescopic boom drive motor.

[0020] A support column 12 is erected on the bow deck 11 of the hull, and a telescopic boom 13 is horizontally supported on this support column 12. This telescopic boom 13 is configured to be rotatable in the horizontal plane and extendable in its length direction. It is driven by a motor 31. A guide rope 18 hangs down from the tip of the telescopic boom 13. The guide rope 18 can be raised and lowered by means not shown. The end ring portion (ring portion 16) of a mooring rope 15 is suspended from the lower end of the guide rope 18 in an expanded state. This device is positioned on the deck 11 at the bow of the hull and has a mooring rope 15 for mooring the hull to a mooring post 14 on a quay (mooring bollard), for example. The tip of this mooring rope 15 is formed in a loop shape, that is, in the structure of a loop portion 16, and the loop portion 16 is hooked onto (moored to) the mooring post 14. The base end of this mooring rope 15 is provided to be retractable and retractable by a winding machine 17 installed on the hull deck 11. When suspended, the ring-shaped portion 16 at the end of the mooring rope 15 is held in a circular shape when viewed from above. It is also preferable that it be held horizontally. This is because the expanding fittings 22A, 22B, 22C, and 22D hold it in a circular shape of a predetermined diameter in the upper position, and when these fittings 22A, 22B, 22C, and 22D land so as to surround the mooring post 14 in a semi-circular shape, the expanded state due to suspension is released. In this state, when the mooring rope 15 is wound up (pulled) by the winding machine 17, the ring-shaped portion 16 deforms from a perfect circle to an oval shape, thereby securing the mooring rope 15 to the mooring post 14. The ship is then moored to the mooring post 14. Furthermore, this device has a guide rope 18 that suspends the ring-shaped section 16 from the tip of the telescopic boom 13, and this guide rope 18 holds the ring-shaped section 16 (and the mooring rope) so that it can move up and down by motor drive or the like.

[0021] The mooring device of this vessel further includes a ring-shaped portion expanding member 21 (hereinafter referred to as the expanding member 21) that expands and holds the ring-shaped portion 16. This expanding member 21 expands the ring-shaped portion 16 to its maximum circular shape and holds it in the upper position when suspended by a rope, and releases the expansion and holding of the ring-shaped portion 16 when it descends from the upper position and touches the ground in the lower position. The specific configuration will be described later. Furthermore, the tip of the telescopic boom 13 is equipped with a camera 19 that captures images of the area below it. A camera with an autofocus function is preferable. The remote control device 32 displays the images captured by the camera 19 on its monitor and, based on these images, extends and retracts the telescopic boom 13, rotates it, and raises and lowers the guide rope 18 (ring-shaped section 16) directly above the mooring post 14. This is operated by a worker on the ship's side.

[0022] Furthermore, the expanding member 21 has a plurality of metal guide pieces 22A, 22B, 22C, and 22D. The upper ends of the guide pieces 22A, 22B, 22C, and 22D are pinned to the guide cable 18, and the lower ends of a pair of guide pieces 22A and 22B are respectively locked to two opposing positions (180 degrees apart) on the ring-shaped portion 16. The expanding member 21 opens the ring-shaped portion 16 and suspends it horizontally. Figure 3(a) shows that when the ring-shaped end 16 of the mooring rope is suspended by the guide rope 18, four identically shaped guide pieces 22A, 22B, 22C, and 22D are placed at equal intervals in the semicircular portion of the opening circle of the ring-shaped end 16 on the mooring rope 15 side. The lowest end of the guide rope 18 is inserted through the through holes in the upper ends of each of these four L-shaped guide pieces 22A, 22B, 22C, and 22D (of a predetermined length). These guide pieces 22A, 22B, 22C, and 22D are made by joining a reinforcing orthogonal plate to a rectangular strip to form an L-shaped cross section, or by bending a single plate to form an L-shaped cross section. Note that these four guide pieces 22A, 22B, 22C, and 22D are molded to the same size and shape for use.

[0023] Furthermore, a cylindrical ring 25 (a ring with a small diameter opening) is positioned and connected to the four guide pieces 22A, 22B, 22C, and 22D at a position higher than the midpoint in the longitudinal direction of the four guide pieces 22A, 22B, 22C, and 22D. The four metal pieces 22A, 22B, 22C, and 22D are pin-connected to four ear-shaped parts protruding from the outer surface of this ring. The diameter of the ring 25 is smaller than the maximum opening diameter of the ring-shaped part 16, and the semicircular parts of the ring-shaped part 16 are connected to and suspended from the lower ends of the four metal pieces 22A, 22B, 22C, and 22D. In other words, the four metal pieces 22A, 22B, 22C, and 22D are rotatably supported in a vertical plane by a cylindrical ring 25 positioned above the halfway point of their length, with a pin as the pivot point. The upper ends of these metal pieces 22A, 22B, 22C, and 22D are connected to the lower end of the rope 18, and their lower ends are connected to the ring-shaped portion 16 by passing the string through the holes. Figure 3(a) shows the state in which the metal pieces 22A and 22B located at both ends of the two pieces and the ring-shaped portion 16 expand to form an isosceles triangle and are suspended. Figure 3(b) shows that the ring-shaped portion 16 forms a large ring with the four metal pieces 22A, 22B, 22C, and 22D. Furthermore, in Figure 4(a), when the suspended ring-shaped section 16 lands (sets contact with the ground), the metal pieces 22A, 22B, 22C, and 22D become parallel (perpendicular) to each other. This is because the mooring rope 15 is wound up by the winding machine 17, causing it to wrap around the bit 14 for mooring. In Figure 4(b), the ring-shaped section 16 is secured to the mooring post 14 by the winding machine 17, causing the ring to become smaller.

[0024] To ensure that the expanding member 21 forms a circle with its maximum diameter when suspended, it is desirable to connect the two intersection points of the diameter connecting the constricted end (winding side end) and tip of the expanding member 21 and a diameter perpendicular to it, with an expanding metal piece or string. The guide string 18 extends vertically to the center of the straight line connecting these two intersection points, and its lower end is connected. It is important that this expanding member 21 maintains its maximum diameter as a circle and is held horizontally. Furthermore, when the ring-shaped section 16 is expanded by the expanding member 21 and maintains its circular shape, and the guide rope 18 descends, it is pulled towards its constricted end by the winding machine 17, causing it to take on an oval shape. At this time, the connecting parts of the suspended expanding guide pieces 22A, 22B, 22C, and 22D are provided on the constricted side of the ring-shaped section 16 so that they do not come into contact with the mooring post 14 (made of metal) and be damaged. When the ring-shaped section 16 is expanded with the four metal pieces 22A, 22B, 22C, and 22D, the connecting parts of these four pieces to the ring-shaped section are symmetrical (with respect to the axis of tension) and are connected and positioned only on the semicircular portion on the constricted side. In short, when expanding the ring-shaped portion 16 to maintain its circular shape, the expansion guide pieces 22A and 22B are positioned at two locations 180 degrees apart from the circle in a plan view, and perpendicular to the winding direction. This is intended to avoid obstructing the field of view for confirming the bit position during imaging with the camera 19, to avoid causing obstacles or resistance during the winding of the mooring rope 15, and to prevent damage to the components during winding. In other words, the above structure has advantages such as improved workability by ensuring a clear field of view for the camera 19, prevention of damage to the extension hardware, and not interfering with the winding operation.

[0025] The telescopic boom 13 is operated by a worker on the ship's side, and in this case, a camera 19 that captures images of the area below is positioned at the tip of the telescopic boom 13. The camera captures the position of the lower end of the guide rope 18, and the worker confirms this on a monitor. When the guide rope 18, which is the rope at the tip of the boom, is positioned directly above the mooring post 14 (quay), the rope 18 is lowered (up and down operation) to lower the ring-shaped part 16 so that the mooring post (the base end is cylindrical) 14 is surrounded by the ring-shaped part 16 (alignment operation of the ring-shaped part and the mooring post). When the lowering is complete (the ring-shaped part 16 lands), the mooring rope 15 is wound up by the winding machine 17 on the ship's side, and the mooring operation is completed. At this time, the telescopic boom 13 is held with its tip and the guide rope 18 positioned directly above the mooring post 14. When positioned at the lower end of the guide rope 18 and moving up and down by the guide rope 18, the metal pieces 22A and 22B, which are the expanding members 21, form a pair. One piece is attached to a part of the circumferential direction of the ring-shaped portion 16, and the other metal piece is attached to the opposite position in the circumferential direction of the ring-shaped portion 16 (approximately 180 degrees apart). When these metal pieces 22A, 22B, 22C, and 22D are suspended from the rope, their lower ends are held apart by a predetermined distance from each other, thereby expanding the ring-shaped portion 16 into a circular shape and holding it horizontally.

[0026] Figures 5(a), (b) and 6 show reference examples of ship mooring devices according to the present invention, particularly alternative configurations of the expanding member 21 of the ring-shaped portion 16. In these diagrams, the guide rope 18 has its lower end tied to an ear formed in the middle of the length of a horizontal bar 26, which is, for example, a metal plate. A pair of ropes 27A and 27B hang vertically from both ends of the horizontal bar 26, and the lower ends of these two ropes 27A and 27B are fixed to two points (diameters) 180 degrees apart on the loop portion 16 of the mooring rope 15. That is, the horizontal bar 26 and the two ropes 27A and 27B constitute the expanding member 21. After hooking this loop portion 16 (loop) onto the mooring post 14 and then touching the ground, it is wound up in the same manner as described above using the winding machine 17. That is, the loop portion 16 deforms from a circular shape to a roughly oval shape, ensuring secure mooring. The length of the horizontal bar 26 is approximately the same as the maximum diameter of the loop portion 16. When releasing, the winding is loosened in the opposite direction to described above, and the loop portion 16 is lifted up via the expanding member 21 using the rope. The mooring rope 15 will be made of the same material as conventional ropes. The winding mechanism 17 and the telescopic arm 13 can also be made of a commonly known configuration. The materials for these will also be selected considering weight reduction and strength. Commercially available products can be used for the camera 19, monitor, and remote control (control device 3). Figure 6 shows the overall configuration of the device. The other configurations are the same as in the above embodiment.

[0027] Figures 7 and 8 show a ship mooring device according to another reference example of this invention. In this example, in addition to the above example, a guide pipe 51 is fixed vertically to the tip of the telescopic boom 13. The guide pipe 51 is made of a lightweight material and has a telescopic structure. This structure is made by fitting together multiple segmented pipes of different diameters coaxially to make it extendable and extendable, and its overall length is variable. This structure is used, for example, in fishing rods. The upper end is thicker, and the lower part gradually becomes thinner. In the guide pipe 51, which consists of multiple segmented pipes, a guide rope 18 is loosely inserted into its internal space. This is to prevent the guide rope 18 from swaying. The guide rope 18 moves vertically up and down within the guide pipe 51 due to its own weight, etc. Furthermore, it is lifted by winch drive. In this way, the guide pipe 51 has a structure that allows it to be extended and retracted. It is a telescopic structure in which multiple short pipes are connected in a retractable manner. Furthermore, a flange-shaped stopper is fixed at a predetermined height position at the lower end of the guide rope 18. This stopper contacts the lower end of the guide pipe 51 and rises, shortening the pipe while winding up the guide rope. The guide rope drive winch is fixed to the tip of the telescopic boom, and the motor for extending and retracting the telescopic boom is fixed to the base end of the boom. The other components will be the same as those in the example above. Furthermore, they will produce the same effects. The advantage of this device configuration is that, because the rigid, hollow pipe 51 surrounds the string-like (wire, etc.) guide rope 18 inside the tube, the coaxial alignment of the ring-shaped section 16 and the mooring post 14 during mooring operations can be performed accurately and quickly in conjunction with imaging from the fixed camera 19. It can also quickly respond to the movement of the ship and positional displacement caused by deformation of the ring-shaped section 16 suspended from the guide rope 18. [Industrial applicability]

[0028] This invention is useful as a mooring device technology for ship-side workers to perform mooring and unmooring operations in the absence of quay-side workers. [Explanation of Symbols]
