Description

Technical Field

[0001] The invention belongs to the technical field of ship design, and in particular relates to an anti-rolling auxiliary boarding device for a floating power generation platform. Background Art

[0002] In severe wind and wave conditions, the platform will produce six degrees of freedom movement. The damping coefficient of the platform in the roll direction is small, which makes it more likely to produce violent swaying movement, affecting the operation stability and safety of the platform. Therefore, it is necessary to take certain anti-rolling measures to achieve the operation stability of the platform and improve the operation efficiency and safety. At the same time, since it is equipped with key power generation equipment and is subjected to the inertial force generated by wind and waves from the outside, excessive roll affects the safety of the platform itself and the normal operation of key power generation equipment. Therefore, the requirements for platform anti-rolling are more stringent. The floating power generation platform is moored in the operating sea area for a long time to transmit electricity to the outside. The pontoons are arranged on the left and right sides of the platform. When rolling, the pontoons will rise and sink. Due to the change in the draft of the pontoons, a reverse restoring moment is generated. The pontoons are far away from the center line of the platform, and the bending moment force arm is large, so it is more significant to suppress the platform's roll movement.

[0003] When boarding a departing ship, helicopters or pilot ladders are generally used. Helicopters require a platform equipped with a corresponding landing pad and corresponding fire-fighting facilities, etc., and the transportation cost is high, so most ships use pilot ladders. Pilot ladders are ladders used for pilots to board and leave the ship. Generally, a combination of inclined ladders and soft ladders is used. Pilots have to take risks to provide pilotage services for ships through pilot ladders, and accidents of accidental falls into the sea are common.

[0004] Floating power generation platforms have a periodic demand for a large number of operators to board, but the operators often do not have the corresponding boarding capabilities of pilots, and the risks of getting on and off the platform are greater. Summary of the invention

[0005] The purpose of the present invention is to provide a floating power generation platform anti-rolling auxiliary boarding device, which can achieve the function of reducing the rolling of the floating power generation platform / ship and reducing the risk of boarding personnel.

[0006] The technical solution of the present invention is as follows: a floating power generation platform anti-rolling auxiliary boarding device, comprising an anti-rolling auxiliary boarding device arranged on the port and starboard sides of the ship, which can effectively reduce the rolling of the hull and reduce the risk of boarding personnel.

[0007] The anti-rolling auxiliary boarding device is arranged at a position 1 / 2 of the ship's length away from the stern.

[0008] The anti-rolling auxiliary boarding device comprises a pontoon, a ballast tank, a pontoon railing, a truss, a boarding ladder, a mooring pile, a lug plate, a pin shaft, and a locking piece.

[0009] The pontoon is a rectangular floating body, with a ballast tank at the bottom, a platform at the top that is flush with the boarding deck of the personnel transfer ship, mooring piles on the top of the pontoon, pontoon railings around the platform on the top of the pontoon, and a truss connecting the pontoon and the power generation ship.

[0010] The bottom of the truss is welded to the top of the pontoon, and the top of the truss is connected to the boarding deck of the power generation ship through a pin shaft and a lug plate.

[0011] The ear plate is welded to the boarding deck of the power generation ship, and the truss is connected to the boarding deck of the power generation ship through a pin shaft, so that the buoyancy box and the power generation ship form a whole.

[0012] The pin shaft is used to be inserted into the top end of the truss and the opening of the ear plate from the side, and a locking piece is used to prevent the pin shaft from sliding out, thereby fixing the truss on the boarding deck of the power generation ship.

[0013] The pin shaft adopts a double pin shaft to form a rigid fixation, or adopts a single pin shaft to form a hinged fixation.

[0014] The locking piece is used to prevent the pin shaft from sliding out laterally after the pin shaft connects the power generation ship and the truss.

[0015] The buoyancy tank railing is welded to the top of the buoyancy tank.

[0016] The beneficial effect of the present invention is that the present invention can reduce the safety risk of boarding. The boarding pontoon is connected to the power generation platform by a detachable pin shaft, and the pontoon platform is basically flush with the boarding deck of the personnel transfer ship. They are connected as a whole by cable piles, which reduces the boarding height and greatly reduces the boarding risk of operators. The anti-rolling auxiliary boarding device is adopted to suppress the platform rolling, reduce the boarding risk of operators, and ensure the safety of the floating power generation platform operation.

[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-3 As shown, the anti-rolling auxiliary boarding device of the floating power generation platform includes an anti-rolling auxiliary boarding device which is arranged about 1 / 2 of the ship length from the stern and located on the left and right sides of the ship, and can effectively reduce the rolling of the hull and reduce the risk of boarding personnel.

[0026] The anti-rolling auxiliary boarding device comprises a pontoon 1, a ballast tank 2, a pontoon railing 3, a truss 4, a boarding ladder 5, a mooring pile 6, an ear plate 7, a pin 8, and a locking member 9.

[0027] The pontoon 1 is a rectangular floating body, and a ballast tank 2 is provided at the bottom of the pontoon 1 to adjust the draft of the pontoon 1; the top of the pontoon 1 provides a personnel boarding platform that is flush with the boarding deck of the personnel transfer boat 11; mooring piles 6 are arranged on the top of the pontoon 1, and the pontoon 1 is fastened to the personnel transfer boat 11 through the mooring piles 6 during boarding; pontoon railings 3 are arranged around the platform on the top of the pontoon 1 and welded to the top of the pontoon 1. The truss 4 connects the pontoon 1 and the power generation ship 10, and the bottom of the truss 4 is welded to the top of the pontoon 1, and the top of the truss 4 is connected to the boarding deck of the power generation ship 10 through the pin 8 and the ear plate 7. The ear plate 7 is welded to the boarding deck of the power generation ship 10, and the truss 4 is connected to the boarding deck of the power generation ship 10 through the pin 8, so that the pontoon 1 and the power generation ship 10 form a whole.
