Embodiment 1

[0026] Example 1: The self-adjusting single point mooring system of the present invention includes a connecting device, a buoy device and a mooring device. Such as figure 1 , 4 shown.

[0027] The connecting device includes a damping connecting arm 2 and a connecting rod 3 , one end of the damping connecting arm 2 is rigidly connected with the hull 1 , and one end of the connecting rod 3 is docked with the damping connecting arm 2 . Such as figure 2 As shown, one end of the connecting rod 3 extends into the inside of the damping connecting arm 2 to connect with the piston 14, and the inside of the damping connecting arm 2 is filled with magnetorheological fluid 15, and the connecting rod 3 can be inside the damping connecting arm 2 back and forth motion.

[0028] The buoy device includes a swivel joint 4, a mooring buoy 5, a rotating shaft 6 and a mooring turntable 7, the mooring turntable 7 is located at the bottom of the buoy device, and the rotation shaft 6 is arrang...

Abstract

The invention discloses a self-regulation type single point mooring system. The self-regulation type single point mooring system is formed by a mooring device, a floating cylinder device, a connecting device and a control device, wherein the mooring device comprises a mooring cable, a connecting chain, a suspending heavy block and an undersea anchoring device; the floating cylinder device is formed by a mooring rotary disk which is arranged at the bottom end, a rotating shaft, a mooring floating cylinder and a rotating connector; the connecting device is provided with a damping connecting arm and a connecting rod; and the mooring floating cylinder can do 360-degree rotation along the rotating shaft through the rotating connector, the damping connecting arm is rigidly connected with a ship body, the connecting rod is in butt joint with the damping connecting arm after being hinged with the mooring floating cylinder, and thus the ship body can do 360-degree rotation along a floating cylinder. According to the self-regulation type single point mooring system disclosed by the invention, the recovery ability and the stability of the mooring system can be increased by adding the suspending heavy block, the mutual winding of vertical tubes is avoided due to the application of the rotating shaft and the rotating connector, the operation safety is ensured, and the connecting device under the action of the control device is rigid and flexible.

Description

technical field [0001] The invention belongs to the technical field of mooring, and in particular relates to a self-adjusting single point mooring system. Background technique [0002] Floating production storage unit (FPSO) has strong functions and wide operating water depth (20~2000m), which is the most mainstream form of offshore oil and gas development and production facilities. FPSO is composed of a hull and mooring system for oil production and storage. The mooring system for FPSO not only undertakes the role of positioning the hull, but also has the function of oil and gas exploitation. Therefore, it is of great significance to design an efficient and safe mooring system matching with FPSO. [0003] At present, the mooring system applied to FPSO is mainly single-point mooring system, which is mainly due to the good "weathervane effect" of single-point mooring. After adopting single-point mooring, the hull rotates 360°. Stop rotation where the mooring load is the sma...
