Background
The single-point mooring device is characterized in that a marine engineering ship is moored on another fixed or floating structure in a single-point mode, and the ship can do 360-degree rotary motion along with stormy waves and currents around the structure due to the wind vane effect, so that the stress of the marine engineering ship is minimum.
When an ocean engineering ship encounters emergency such as extremely severe sea conditions, equipment or structural failure and the like, the single-point mooring system and the ship need to be quickly disconnected so as to avoid overloading of the single-point mooring system and serious accidents. The soft rigid arm mechanism of the single point mooring system belongs to a large member, and the rapid release technology of the soft rigid arm mechanism is the key for ensuring the safety of an ocean engineering ship and the single point mooring system. The quick release scheme fully considers the influence of environmental factors such as seasons, weather conditions, sea conditions and the like on the operation ship, the limitation of site conditions and construction technology, the release period and the safety of operators, and the quick release technology needs to have reasonability and operability.
The conventional release of a single point mooring is the release between the mooring leg and the mooring rigid arm, and the most common connection and release patterns are the release of the mooring leg pin shaft and the release of the mooring leg flange bolt. In the conventional release scheme, under the condition of calm sea, the removal operation can be carried out due to the fact that the stress of the removed part is small in the processes of pulling the pin shaft and removing the bolt, the conventional release generally needs 3-4 days at least, and the requirement for quick release cannot be met. Therefore, it is necessary to design and develop a fast release single point mooring device which meets the requirement.

Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, the soft rigid arm single-point mooring device with the slider capable of being rapidly disengaged is applied to a tower type soft rigid arm single-point mooring device, and comprises a mooring boat 1, a fixed tower 11 and a mooring rigid arm 10, wherein one end of the mooring rigid arm 10 is connected with the fixed tower 11, the other end of the mooring rigid arm 10 is hinged with a mooring leg 9, and the mooring leg 9 can rotate around the hinged point. The other end of mooring leg articulates there is connecting seat 8, and fixed welding has mooring support 4 on the ship of mooring 1, is equipped with the slant slide on mooring support 4, is equipped with slider 7 in the slant slide, and slider 7 and connecting seat 8 fixed connection, the top of slant slide are equipped with the hydraulic clamp 6 that is used for fixed slider 7.
According to the invention, the inclined slideway and the vertical direction form a certain angle, and when the slide block 7 slides downwards from the inclined slideway, horizontal and vertical acting forces are generated, so that the mooring leg 9 can be pulled quickly and effectively.
In order to safely and reliably restrain the sliding block 7 in the process of sliding downwards, the mooring winch 2 is further arranged on the mooring boat 1, the mooring winch 2 is provided with the mooring cable 3, and the other end of the mooring cable 3 is connected with the connecting seat 8.
In order to facilitate the slider 7 to slide downwards and then separate from the inclined slide way, the mooring bracket 4 is provided with the horizontal slide way 5, the horizontal slide way 5 is intersected with the lower end of the inclined slide way, and the slider 7 slides downwards from the inclined slide way and then enters the horizontal slide way 7 from the intersection to slide. The horizontal slideway 5 is arranged at the lower end of the oblique slideway and is specifically determined in the following way: when one end of the mooring rigid arm 10 connected with the mooring leg contacts the water surface, a horizontal slideway is arranged at the position of the sliding block 7 on the oblique slideway, and at the moment, the sliding block 7 enters the horizontal slideway 5 from the intersection of the oblique slideway and the horizontal slideway 5 to slide horizontally.
When the single-point mooring device is in a balanced state, the mooring legs 10 are in a vertical state, and the mooring bracket 1 and the fixed tower 11 are not subjected to horizontal mooring force. When loads such as wind, wave, flow, ice and the like act on the mooring ship 1 to enable the mooring ship 1 to be far away from or close to the fixed tower 11, the mooring rigid arm 10 is lifted, the mooring leg 9 rotates around the hinged point, and the single-point mooring device provides restoring force opposite to the movement direction by means of the self weight and the weight of ballast water of the mooring rigid arm 10, so that the mooring ship 1 is pulled back or pushed back to a balanced state.
As shown in fig. 2, when the mooring vessel 1 is in a normal mooring state, the slider 7 is locked by the hydraulic clamp 6 at the highest point, the mooring cable 3 is connected to the upper end of the connecting seat 8, and the mooring winch 2 does not work. When the mooring ship 1 is in a quick release state, an emergency drain valve of the mooring rigid arm 10 is opened to discharge ballast water, the mooring winch 2 is started to tighten the mooring cable 3, the sliding block 7 is released from the hydraulic clamp 6, and the sliding block starts to move downwards along the inclined slide way on the mooring bracket 4. The slider 7 drives the mooring leg 9 and the mooring rigid arm 10 to descend through the connecting seat 8, and moves to the lowest point of the mooring rigid arm 10 to be contacted with the water surface, as shown in fig. 3. The mooring boat 1 can start to move away from the fixed tower 11 under the action of the auxiliary thrust, the sliding block 7 continues to slide downwards until the mooring boat moves into the horizontal slideway 5, the mooring boat 1 continues to move away from the fixed tower 11, and the sliding block 7 starts to move horizontally in the horizontal slideway 5, as shown in fig. 4. The sliding block 7 moves in the horizontal sliding way 5 until the sliding block is separated from the horizontal slideway 5, the mooring bracket 4 is completely separated from the mooring leg 9, at the moment, the mooring winch 2 is still tightened and slowly lowered, and the mooring rigid arm 10 is placed in the barge 12 for mooring operation, as shown in fig. 5. After the mooring rigid arm 10 and the mooring leg 9 are safely fastened in the barge 12, the head of the mooring line 3 is removed, as shown in fig. 6, the mooring winch 2 works to roll up the mooring line 3, and the mooring vessel 1 can be driven away from the mooring point and quickly transferred to a safe place.
Traditional release operation needs the staff to arrive mooring leg and mooring steel boom flange or round pin axle department, need utilize specialized tool to carry out dismantling of bolt, retrains relative motion with the help of the chain block, and what the operation in-process received influences such as wind, unrestrained, stream produces rocks great, and operating time and quality can not obtain the assurance. And after the mooring rigid arm is dismantled, part of operators need to descend to the sea surface along with the mooring rigid arm, and the operators are required to have skillful offshore construction experience.
The single-point mooring device can complete the quick release between the mooring bracket and the mooring leg within eight hours, greatly shorten the release operation time, fully improve the efficiency of single-point mooring release operation and reduce the configuration of a special detaching tool and the workload of operators. The invention has simple structure design, is easy to assemble and maintain, and can greatly reduce the operation cost.
The sliding block, the sliding way, the connecting seat and the hydraulic clamp which are specifically used in the soft rigid arm single-point mooring device can adopt the existing mature products.
The scope of the present invention is not limited to the above-described embodiments, and any simple modifications, equivalent changes and decorations in accordance with the technical essence of the present invention to the above-described embodiments are within the technical scope of the present invention by those skilled in the art.
