[0057] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a method and device for ship berthing and unberthing at a dock.
[0058] like Figures 1 to 10 As shown, an embodiment of the present invention provides a method for berthing and unberthing ships at a dock, based on a dock and ship 1 adjustment device, the dock includes a first pier 2 and a second pier 3 arranged at intervals along a first direction, the first pier 2 includes a first pier 21 and a second pier 22 arranged in sequence along a second direction, the distance between the first pier 21 and the shore is greater than the distance between the second pier 22 and the shore, and the first direction is perpendicular to the second direction.
[0059] Specifically, the wharf includes a first pier 2 and a second pier 3 which are symmetrically arranged along a first direction, and each pier is provided with a plurality of piers in sequence along a second direction, wherein the first direction is usually parallel to the coastline direction of the shore, and the second direction is perpendicular to the first direction. The first pier 2 includes a first pier 21, a second pier 22 and a plurality of piers arranged in sequence, wherein the distance between the first pier 21 and the shore is greater than the distance between the second pier 22 and the shore, that is, the first pier 21 is located at the end of the first pier 2 away from the shore, and the second pier 22 is provided at a preset distance from the first pier 21 along the second direction, and the first pier 21 can be used as a fulcrum for the rotation of the ship 1. Between the first pier 2 and the second pier 3 is the berth waters where the ship 1 docks, and the ship adjustment device can be a device that can provide power to the ship 1, such as a tugboat 4 and a winch 5, and the ship adjustment device is used to provide power to the ship 1 when the ship 1 docks and leaves the berth, thereby adjusting the position and rotation direction of the ship 1.
[0060] For example, the berth water area between the first pier 2 and the second pier 3 of the heavy cargo terminal in this embodiment is about 58.3m wide, and each of the two piers is provided with multiple piers, and the spacing between the piers in the two piers is 33.01m, 27.68m, 32.80m, and 22.7m respectively. The length of the first pier 2 is about 178.93m, the length of the second pier 3 is about 177.33m, the top elevation of the two piers is 21.8m, the width of the first pier 2 is about 9m, and the width of the second pier 3 is 2.44m. In the case of high water flow speed, high wind speed, limited channel space, and limited port space, a series of adverse effects are brought to the berthing of large ships 1. In order to facilitate the berthing and unberthing of the ship 1, the pier fenders of the first pier 2 and the second pier 3 are selected from roller rubber fenders, which can meet the energy absorption requirements of the ship 1 when berthing.
[0061] The ship berthing and unberthing method comprises:
[0062] S100, when the ship 1 berths along the first direction, determine whether the first distance between the bow of the ship 1 and the second pier 3 meets the preset safety distance, and if so, control the ship 1 to enter the berthing waters between the first pier 2 and the second pier 3 by using the reverse cable connecting the ship 1 and the first pier 21 and the ship 1 adjustment device.
[0063] Specifically, when the ship 1 berths from the first pier 2 to the second pier 3 along the first direction, the ship 1 first needs to go along the edge of the pier against the direction of the water flow ( Figure 2The second pier 3 is located upstream of the water flow, and the first pier 2 is located downstream of the water flow) and the ship 1 travels to the vicinity of the berth water area, that is, close to the first pier 21 located at the edge of the first pier 2. As the ship 1 travels forward, the distance between the bow and the second pier 3 will continue to decrease, that is, the first distance will continue to decrease. When the first distance meets the preset safety distance, the bow and the first pier 21 in the first pier 2 are connected by a reverse cable, and the rotation angle of the ship 1 is adjusted with the cooperation of the ship adjustment device, so that the ship 1 enters the berth water area between the first pier 2 and the second pier 3. Among them, the safety distance can be set to a reasonable distance range according to the first pier 2 and the second pier 3. When the first distance belongs to the range of the safety distance, it means that the first distance meets the preset safety distance. The setting of the safety distance can ensure that the ship 1 will not collide with the second pier 3 and other facilities on the dock due to the rotation of the hull while obtaining the maximum rotation space, and can effectively ensure the safety and stability of the ship 1 when berthing. The ship adjustment device can be a tugboat, or the tugboat 4 and the winch 5 can cooperate to control the ship 1 to enter the berthing waters. The ship adjustment device can apply external force when the ship 1 is berthing, so that the ship 1 can accurately enter the berthing waters in a preset manner.
[0064] It should be noted that when a ship is sailing upstream to berth, the direction of the force of the water flow on the ship is from the bow to the stern, providing a braking force for the ship. When approaching the dock, the ship can use the resistance of the water flow to control its speed more accurately through appropriate power or external force, and approach the dock slowly and steadily, so as to accurately grasp the timing and location of docking and reduce the probability of accidents such as collision with the dock due to excessive speed.
[0065] S200, when the ship 1 leaves the berth, the bow is connected to the second pier 22 by the reverse cable, and the ship 1 is controlled to move backward; when the ship 1 sails out of the berth water area by a preset second distance, the stern of the ship 1 is connected to the first pier 21 by the reverse cable, and the ship 1 is controlled to turn out of the berth water area by the ship 1 adjustment device.
[0066] Specifically, when the ship 1 is about to leave the berth, that is, when the ship 1 is about to leave the berth waters, the bow is connected to the second pier 22 of the first pier 2 by a reverse cable. After the connection, the ship 1 is controlled to move backward, and the length of the reverse cable is appropriately adjusted during the backward process, so that the ship 1 always remains stable during the backward process, which can effectively prevent the ship 1 from being excessively deviated due to the flow pressure of the water flow during the backward process, thereby affecting the stability of the ship 1. When the hull of the ship 1 sails out of the berth water area by a preset second distance, the bow of the ship 1 will not collide with the dock if it is turned out. The ship 1 will stop retreating, and the reverse cable connecting the bow and the second pier 22 will be released, and the stern and the first pier 21 will be connected by the reverse cable. At this time, since a part of the hull has sailed out of the berth water area, the sailed part of the hull may rotate due to the influence of the water flow in the absence of the power for the ship 1 to retreat, and under the traction of the reverse cable, the ship 1 will rotate around the first pier 21. At this time, the turning angle and speed of the ship 1 are controlled and adjusted by the ship adjustment device to avoid collision between the ship's side and the facilities on the dock due to excessive rotation. The remaining hull is smoothly turned out of the berth water area through the control and adjustment of the ship adjustment device. After the ship 1 sails out of the berth water area, the stern reverse cable is released, the ship adjustment device is withdrawn, the ship 1 enters the vehicle, steers the right rudder, and sails out of the berth.
[0067] In this embodiment, the first pier 21 in the wharf is connected and matched with the ship 1, so that the ship 1 can stably rotate with the first pier 21 as a fulcrum when berthing and leaving the berth, avoiding collision with the second pier 3 and other facilities on the wharf after deviation during the rotation process, and controlling and adjusting the ship 1 through the ship adjustment device, so that the ship 1 can enter and exit the berth water area more smoothly and safely, wherein the first pier 2 and the second pier 3 are arranged at intervals along the first direction, the piers of the first pier 2 are arranged in sequence along the second direction, the first direction and the second direction are perpendicular, and the distance between the first pier 21 and the shore is greater than the distance between the second pier 22 and the shore, so that the position of the ship 1 is adjusted by two piers with a certain distance, which can avoid the ship 1 from deviating from the preset driving route. When the ship 1 is berthing along the first direction, it is judged whether the distance between the bow and the second pier 3 meets the safety distance. The safety distance can ensure that the ship 1 has the maximum rotation space and does not collide with the second pier 3 and other facilities in the wharf. When the safety distance is met, the ship 1 is connected to the first pier 21 by a reverse cable. During the rotation of the ship 1, the ship 1 can be rotated around the first pier 21 by the traction of the reverse cable, and the rotating ship 1 is controlled and adjusted by the ship adjustment device, so that the ship 1 can quickly and smoothly enter the berthing waters between the first pier 2 and the second pier 3. When the ship 1 leaves the berth, the bow is first connected to the second pier 22 by the reverse cable to ensure that the hull is kept stable when the ship 1 retreats. When the ship 1 sails out of the berthing waters for the second distance, the stern is connected to the first pier 21 by the reverse cable. At this time, under the combined action of the water flow and the reverse cable, the ship 1 is rotated around the first pier 21 by the traction of the reverse cable, and the rotating ship 1 is controlled and adjusted by the ship adjustment device, so that the ship 1 can smoothly turn out of the berthing waters, avoiding the risk of excessive rotation of the ship 1 due to the action of the water flow, causing the risk of collision between the ship side and the dock. During the berthing and unberthing process of the ship 1, the ship 1 is rotated with the first pier 21 as the fulcrum through the connection of the reverse cable, so as to maintain the stability of the ship 1 during the rotation process, reduce the risk of collision between the ship 1 and the wharf and between the ships 1, and ensure safety. Through the cooperation of the ship adjustment device, the posture of the ship 1 is accurately controlled, and the path of the ship 1 entering and exiting the berthing waters is optimized, so that the ship 1 can enter and exit the berthing waters more smoothly, reduce the time delay of berthing and unberthing, improve the efficiency of the ship 1 berthing and leaving the berthing waters, and reduce the safety risk of large ships in the narrow space of the harbor.
[0068] It should be noted that the tugboat 4, as a water vehicle that assists the ship 1 in maneuvering, applies external force to the target ship 1 through its own power system. When the tugboat 4 pushes the port side of the ship 1, it will give the ship 1 a force in the port direction. This force will break the original force balance state of the ship 1 in the berth, causing the ship 1 to tend to rotate around a certain center point. At the same time, the ship 1 can be towed by the winch 5 located on the dock slope, so that the ship 1 can quickly enter the berth waters under the action of the traction force. The first pier 21 is an important support point for the ship 1 to turn in and out of the berth waters. Its surface is usually equipped with fenders to protect the ship 1 from collision damage during the berthing process. The connection between the ship 1 and the first pier 21 provides an accurate positioning direction and preliminary fixation for the ship 1. As the ship 1 rotates, the port side of the ship 1 can be gradually approached to the fender of the first pier 21 by adjusting the reverse cable. When the port side of the ship 1 approaches the fender, the reverse cable can prevent the ship 1 from excessively approaching or colliding with the pier due to external forces such as traction or water flow, play a role in buffering and accurately controlling the distance, and ensure that the port side of the ship 1 and the fender maintain a close distance. The appropriate berthing state can avoid damage caused by collision and ensure the stability of the ship 1 in the berth. The fender can be reasonably selected according to the model of the ship 1 and the on-site environment. For example, the effective impact energy of a 5000DWT ship is 78.75KJ. The fender of the first pier 21 can be DA120-40 roller rubber fender with a maximum deformation of 260mm, a reaction force of 820KN, and an energy absorption of 60KN-M. The other piers use DA-A500H1500L standard reaction type rubber fender with a standard reaction force of 505kN, which can meet the energy absorption requirements of the ship 1 when berthing.
[0069] Optionally, the ship adjustment device includes a tugboat 4; the control of the ship 1 entering the berthing waters between the first pier 2 and the second pier 3 by using the cable connecting the ship 1 to the first pier 21 and the ship adjustment device includes:
[0070] Connecting the bow to the first abutment 21 via a cable;
[0071] The tugboat 4 controls the ship 1 to enter the berth water area.
[0072] Specifically, Figures 2 to 4As shown, the bow is connected to the first pier 21 in the first pier 2 by a reverse cable, and the reverse cable is adjusted to a suitable length to control the ship 1 to enter the first or second car, and the left rudder is operated. The hull uses the rolling fender of the first pier 21 as a fulcrum, rotates around the fulcrum under the traction of the reverse cable, and controls the ship 1 to enter the berthing waters under the push of the tugboat 4. During the rotation process, the length of the reverse cable can be adjusted to keep the position of the ship 1 relatively stable with the first pier 21 during the rotation process to avoid collision during the rotation process. At the same time, since the ship 1 is traveling against the current when berthing, the tugboat 4 pushes the ship 1 at the port position behind the ship 1 to assist the rotation of the ship 1 and adjust the position of the ship 1, so that the bow can quickly and accurately enter the berthing waters, and the adjustment and control of the tugboat 4 can also avoid the collision of the bow with the second pier 3 and other facilities. When the tugboat 4 pushes the ship's hull to be parallel to the first pier 2, the reverse cable connected to the first pier 21 is released, the ship 1 is controlled to move in and steer straight, so that the ship 1 travels in the direction currently horizontal to the first pier 2 and enters the berthing waters, and the tugboat 4 is controlled to push the stern of the ship 1, which can effectively prevent the stern from drifting down and enable the ship 1 to enter the berthing waters more quickly.
[0073] In this optional embodiment, the bow is connected to the first pier 21 by a reverse cable, and the ship 1 can rotate with the first pier 21 within the length of the reverse cable, which can prevent the bow from colliding with the pier of the second pier 3 during the rotation process, and at the same time, it can avoid a lot of adjustment time consumed by the large-scale rotation of the ship 1, thereby improving the berthing speed of the ship 1. Through the power of the ship 1 and the push of the tugboat 4, the rotation speed of the ship 1 is controlled to avoid the risk of collision caused by excessive rotation speed, and at the same time, the berthing route can be accurately controlled to improve the speed of the ship 1 entering the berthing waters.
[0074] Optionally, controlling the ship 1 to enter the berth waters by the tugboat 4 includes:
[0075] When the ship 1 rotates by a preset first angle under the traction of the reverse cable, the rotation direction of the ship 1 is adjusted by pushing the tail of the ship 1 by the tugboat 4;
[0076] When the ship 1 is parallel to the first pier 2, the tugboat 4 is controlled to push the stern until the ship 1 enters the berth waters.
[0077] Specifically, Figure 3 and 4As shown, with the propulsion of the ship 1's own power and the control of the ship 1's rotation by the reverse cable, since the ship 1 is traveling against the direction of the water flow when entering the berth waters, when the ship 1 rotates around a pier at a preset first angle, due to external factors such as the water flow, the ship 1 may not be able to stably rotate around the first pier 21, and needs to be pushed by the tugboat 4 on the port side of the stern to maintain the stable rotation of the ship 1, wherein the first angle can be set according to actual conditions such as the tonnage of the ship 1, the speed of the water flow and the wind speed, and is usually between 30° and 45°. The direction of the ship 1 is continuously adjusted by the pushing of the tugboat 4. When the ship 1 is parallel to the first pier 2, the stern is pushed by the tugboat 4. The ship 1 is controlled to enter the berthing waters under the power of the tugboat 4 and the ship 1 itself. In this process, the pushing force of the tugboat 4 is adjusted according to factors such as the inertia of the ship 1, the speed and direction of the water flow, etc. If the pushing is too fast, the ship 1 may collide with other facilities in the dock. If the pushing speed is too slow, it may be affected by external forces such as the water flow and deviate from the correct position. At the same time, it is necessary to continue to monitor the position and posture of the ship 1 to ensure that the ship 1 enters the berthing waters smoothly and accurately.
[0078] Furthermore, if Figure 5 As shown, when the ship 1 reaches the berthing position, the bow and stern are connected to the piers on the first pier 2 and the second pier 3 respectively, and the length of the connecting cable is adjusted to make the ship 1 fit with one side of the first pier 2, so as to ensure the stability of the ship 1 in the berthing waters and avoid the hull shaking caused by factors such as tides. For example, when the hull completely enters the berth, under the action of flow pressure, the port side of the ship 1 is close to the pier fender of the first pier 2, and the sailors and dock workers at the bow and stern quickly work with cables, and the 4 cables at the bow and stern are connected to the piers on the first pier 2 and the second pier 3 respectively, and the ship 1 stops, and the tugboat 4 leaves, while keeping the cable of the ship 1 moderately tight, and the operators pay attention to safety.
[0079] In this optional embodiment, when the ship 1 rotates to a first angle, the rotation angle of the ship 1 is further controlled and adjusted by the tugboat 4 to prevent the ship 1 from colliding with the dock or deviating from the original position due to unstable rotation when berthing, thereby improving the safety and stability of the berthing of the ship 1, and at the same time reducing the adjustment time and optimizing the berthing path, thereby improving the efficiency of the berthing of the ship 1.
[0080] Optionally, the ship adjustment device further includes a winch 5 arranged on the dock, and the traction end of the winch 5 is connected to the bow; the step of controlling the ship 1 to enter the berth waters by the tugboat 4 includes:
[0081] Through the pushing of the tugboat 4 and the cooperation of the winch 5, the ship 1 is controlled to enter the berth waters.
[0082] Specifically, Fig.10 As shown, the winch 5 is arranged on the bank slope of the dock, and the traction end of the winch 5 bypasses the mooring bollard and is connected to the bow of the ship 1, so that the traction force of the winch 5 controls the ship 1 to enter the berthing waters. First, after the bow and the first pier 21 are connected by the reverse cable, the traction end of the winch 5 drives the bow into the berthing waters, or drives the ship 1 into the berthing waters together with the power of the ship 1 itself, thereby increasing the berthing speed of the ship 1, and controlling the port side of the ship 1 to stick to the fender of the first pier 21 by the reverse cable. When the winch 5 starts to tow the bow through the traction end, the traction end applies a pulling force toward the berth water area. This pulling force should be precisely controlled according to environmental factors such as the size, weight and water flow of the ship 1. During the towing process of the winch 5, the ship 1 gradually moves toward the berth water area. The towing speed needs to be continuously adjusted according to the speed of the ship 1 entering the berth water area to ensure that the ship 1 can quickly and accurately sail to the target berth. The tugboat 4 pushes at the stern to control the turning angle and speed of the ship 1 so that the ship 1 can quickly turn to a suitable angle. With the cooperation of the tugboat 4 and the winch 5, the ship 1 can quickly and stably enter the berth water area to avoid collision with the pier, thereby improving the berthing efficiency of the ship 1 at the dock.
[0083] Optionally, the ship adjustment device includes a tugboat 4; the connecting the stern of the ship 1 to the first pier 21 through the reverse cable, and controlling the ship 1 to turn out of the berth waters through the ship 1 adjustment device, includes:
[0084] Release the reverse cable connecting the bow and the second abutment 22, and connect the stern and the first abutment 21 via the reverse cable;
[0085] The tugboat 4 pushes the side of the ship 1 close to the first pier 2 to control the ship 1 to move out of the berth water area.
[0086] Specifically, Figures 6 to 9As shown, when the ship 1 leaves the berth, that is, when the ship 1 leaves the berth water area, as the ship 1 retreats, the hull gradually moves out of the berth water area. At this time, the ship 1 needs to be controlled and adjusted according to the hull length of the ship 1 out of the berth water area, wherein the hull length of the ship 1 out of the berth water area is the distance the ship 1 retreats. When the distance that the ship 1 retreats is a preset third distance, the third distance can be set according to the width of the berth water area and the length of the ship 1. When the retreat distance of the ship 1 is greater than or equal to the third distance, the ship 1 is controlled to turn out of the berth water area around the first pier 21, which can ensure that the bow will not collide with the pier of the second pier 3 during the rotation process, that is, after the ship 1 sails out of the third distance, the length of the hull remaining in the berth water area will be less than the width of the berth water area. Therefore, when the ship 1 rotates around the first pier 21, the bow will not collide with facilities such as the second pier 3. When the ship 1 retreats the third distance, the ship 1 is controlled to turn out of the berth water area around the first pier 21, and adjustments can be made at the first time the turning-out conditions are met, so that the ship 1 is controlled to turn out at the fastest speed, reducing the time required for the ship 1 to leave the berth water area and improving the unberthing efficiency of the ship 1 in the dock.
[0087] Furthermore, when the ship 1 retreats the third distance, the ship 1 is controlled to stop, the reverse cable between the bow and the second pier 22 is released, the stern is connected to the first pier 21 through the reverse cable, and the reverse cable is adjusted to a suitable length according to the actual situation. At the same time, the tugboat 4 pushes the side of the ship 1 close to the first pier 2 to control the rotation angle of the ship 1 to prevent the stern from drifting down and out of control with the water flow. Under the action of the water flow and the tugboat 4, the ship 1 takes the first pier 21 as a fulcrum, and the bow gradually turns out of the berth water area. When the ship 1 completely passes through the berth water area, the ship 1 is parallel to the water flow direction and abuts against the outer side of the pier at the edge of the dock. The reverse cable between the stern and the first pier 21 is released, and the ship 1 is controlled to enter the vehicle and the right rudder is used to leave the berth water area.
[0088] In this optional embodiment, the timing of controlling and adjusting the ship 1 to turn out is determined by the distance the ship 1 retreats, so that the ship 1 can be quickly controlled to turn out of the berthing waters in the first place. At the same time, through the connection adjustment of the reverse cable and the cooperation of the tugboat 4, deviation and collision of the ship 1 during the turning out process are avoided, thereby reducing the time consumed by the ship 1 to leave the berthing waters and improving the efficiency of the ship 1 leaving the dock.
[0089] Optionally, the controlling the ship 1 to turn out of the berth waters by pushing the side of the ship 1 close to the first pier 2 by the tugboat 4 includes:
[0090] The tugboat 4 pushes the side of the ship 1 close to the first pier 2 to control the turning angle of the ship 1;
[0091] When the turning-out angle reaches a preset second angle, the tugboat 4 stops pushing, and the vessel 1 turns out of the berth water area according to the flow pressure.
[0092] Specifically, Figures 7 to 9 As shown, the ship 1 is controlled to turn out at an angle by pushing the ship 4 against the side of the ship close to the first pier 2. Accurate angle control can avoid the ship 1 from deflecting and colliding, and ensure that the ship 1 leaves the berth waters safely and smoothly. When the turning out angle reaches the preset second angle, the tugboat 4 stops pushing. The preset second angle takes into account the specific layout of the wharf, the water flow conditions in the surrounding waters, the size and maneuverability of the ship 1 itself, and other factors. When the turning out angle reaches the second angle, it means that the ship 1 is already in a suitable position and posture, and can continue to turn out of the berth waters under the action of flow pressure, wherein the flow pressure is the pressure exerted by the water flow on the ship 1. After the tugboat 4 stops pushing, the pressure of the water flow becomes the main external force factor that dominates the movement of the ship 1. At this time, the ship 1 continues to turn out of the berth along the direction of the water flow under the action of the flow pressure. The use of flow pressure can reduce the use time and energy consumption of the tugboat 4, and can also guide the ship 1 to leave the berth more naturally, avoiding the collision of the ship 1 or other unexpected situations caused by excessive use of the tugboat 4, and improving the efficiency of the ship 1 turning out of the berth waters.
[0093] In this optional embodiment, the tugboat 4 can accurately control the turning angle to avoid collision, control the ship 1 to turn out according to a predetermined trajectory, optimize trajectory planning, save time for controlling and adjusting the ship 1, and at the same time, through the rational use of the power of the tugboat 4, reduce energy consumption and equipment wear, and improve the efficiency and safety of the ship 1 turning out of the berth waters.
[0094] It should be noted that in waters with relatively fixed topography, the direction of water flow generally follows the direction from high to low, so the direction of water flow in fixed waters near the dock is usually fixed. If the direction of water flow changes, the direction of rotation of the tugboat pushing the ship can also be changed according to the direction of water flow, so that the rotation direction of the ship needs to be consistent with the direction of water flow, ensuring that the ship can be turned out of the berth waters according to the flow pressure of the water flow after the tugboat 4 is pushed out.
[0095] Optionally, the ship 1 adjustment device further includes a winch 5, and the traction end of the winch 5 is connected to the bow; the controlling the ship 1 to retreat includes:
[0096] The backward movement of the ship 1 is controlled by the power of the ship 1 itself, and the backward movement speed of the ship 1 is controlled by the traction of the winch 5.
[0097] Specifically, Fig.11As shown, when the ship 1 retreats by its own power, the retreat speed of the ship 1 may not be accurately controlled due to the influence of external factors such as water flow and wind force. Therefore, a winch 5 is set on the shore of the dock, and the traction end of the winch 5 bypasses the mooring post and connects to the bow to tow the ship 1, so as to further control the speed of the ship 1 leaving the berth waters, avoid the ship 1 from colliding with the facilities of the dock due to the ship 1 retreating too fast, thereby improving the safety of the ship 1 leaving the berth, and through the traction of the winch 5, the retreat direction of the ship 1 can be further controlled, the retreat stability of the ship 1 can be improved, and the ship 1 can be prevented from deviating from the preset trajectory when retreating, thereby reducing the adjustment time of the ship 1 and improving the efficiency and safety of the ship 1 leaving the berth.
[0098] Optionally, the first pier 2 is provided with a rolling rubber fender; and the ship berthing and unberthing method further comprises:
[0099] When the ship 1 turns, the rolling rubber fender is used as a fulcrum and the turning direction of the ship 1 is controlled by the tugboat 4 .
[0100] Optionally, rolling rubber fenders are provided on the first pier 21 , the second pier 22 and the third pier of the first pier 2 , and standard reaction-force type rubber fenders are provided on the other piers of the first pier 2 .
[0101] Specifically, a rolling rubber fender is provided on the pier of the first pier 2. Unlike ordinary fixed fenders, the rolling rubber fender can roll when subjected to external forces such as squeezing by the ship 1. This rolling characteristic enables it to better adapt to the relative motion changes between the ship 1 and the pier, and can generate a more flexible relationship between the action force and the reaction force during the contact process. Therefore, during the rotation of the ship 1, the rolling rubber fender on the first pier 2 is used as a fulcrum, and the rotation direction of the ship 1 can be more smoothly controlled by the tugboat 4. For example, based on the rolling characteristics of the rolling rubber fender, it can provide a relatively stable and variable angle contact fulcrum during the berthing and unberthing operation of the ship 1. During the berthing and unberthing process of the ship 1, the rolling rubber fender contacts the side of the ship 1 to form a fulcrum, and the rotation direction of the ship 1 is controlled according to the cooperation of the tugboat 4 and the fulcrum, so that the ship 1 can smoothly turn into and out of the berthing waters.
[0102] Furthermore, since the piers of the first pier 2 far from the shore provide a fulcrum for turning during the berthing and unberthing process, rolling rubber fenders can be set on the first pier 21, the second pier 22 and the third pier far from the shore in sequence, so that the ship 1 can smoothly rotate with the rolling rubber fender as a fulcrum during the rotation process, converting the conventional sliding friction into rolling friction, and the rotation angle of the ship 1 can be accurately controlled by the cooperation of the tugboat 4, greatly reducing the squeezing effect of the ship on the pier. For other piers on the first pier 2, standard reaction type rubber fenders can be set on them. The standard reaction type rubber fenders use their own elasticity. When the ship 1 berths and collides, the kinetic energy of the ship 1 can be converted into elastic potential energy and slowly released, avoiding direct collision between the ship 1 and the first pier 2, mitigating the collision process, ensuring the stability of the piers, beams and other components of the pier, and protecting them from damage by strong impact force. At the same time, it can protect the integrity of the ship 1 side structure and prevent deformation, cracking and other damage.
