2.1 Main types of single point mooring
Single point mooring
Definition or description
Any mooring that allows the moored ship to rotate around a single mooring point with the change of wind and sea conditions, so as to be constantly in the position with the minimum resistance of wind, waves and flow is called single point mooring. Sometimes single point mooring device or single point mooring system is referred to as single point mooring. In offshore gas development projects, it is used as the connection link between submarine pipelines and mooring vessels, generally used to transport fluids (such as right side of the pipeline).

The lower section is a special riser, the second section is a vertical columnar buoy, the bottom end of the riser is connected to the bottom foundation, and the anchor section is a tethered frame and the mooring device! The single anchor leg mooring device connected to the ship is composed of a main chain and a turret structure. The upper end of the riser is connected to the bearing in the turret through a universal frame; the riser is connected to the appropriate underwater position of the riser - a fixed bottom chain + independent pipe turret structure is placed in the middle of the swim... The restoring force of the whole device is generated by the buoyancy of the riser and the chain point of the catenary: the bottom of the riser is connected to the underwater hose pipe, the top of the pipe is connected to the moored ship - a rigid yoke, and the bottom of the riser is connected to a set of catenary pipes. The turret structure of the turret mooring device is located inside the bow of the boat, supporting the mooring buoy of the chain! The turret at the bottom of the turret is combined with the chain staggered mooring! Single-point mooring device
The connection between the turntable of the mooring buoy and the moored ship uses a flexible and lightweight yoke,Definition or description: a rigid gear frame with articulated wheels, which is installed on the left side of the single point mooring device and supports roller bearings, and allows the ship on it to rotate according to the characteristics of the weathervane. 2.2.4 Anchor leg anchor leg mooring swivel coupling mooring swivel coupling quick release coupling quick release coupling connect?

Definition and explanation
A mechanical device similar to a square joint, having a pair of orthogonal axes in the horizontal plane, allowing free rotation around orthogonal orbits, used to form an articulated joint between the riser and the target channel to adapt to the pitch, roll and swing movements of the moored ship
A connecting component between the upper buoy of the single point mooring device and the fixed point of the offshore foundation. It can be a pipe, anchor chain or a rotating connection device that can transfer the mooring load between the parts that can rotate around the vertical axis and the relatively static parts in the single point mooring system
The connection device between the moving and the parts of the fluid pipe system in the single point mooring system. It can ensure the continuous transmission of a pressurized fluid (sea, gas, water, etc.) without leakage in the transition section between the rotating and fixed parts
In an emergency, the moored ship can be quickly disconnected from the single point mooring device, and the device can be quickly reconnected when the connection is to be restored
In a floating single point mooring system, in order to make the catenary obtain the required curved shape, it is often a concrete or iron block hung on the catenary
Definition or description

Definition or description
The load acting on the single point mooring buoy and foundation when the single point mooring device is equipped with the maximum load it is designed to moor in the operating environment; or the load acting on the single point mooring buoy and foundation when the single point mooring device is equipped with other smaller loads but will produce a larger load. It includes the mooring load and the mooring load of the single point mooring device.
The maximum load attributable to the mooring cable when the single point mooring device is moored with the largest ship it is designed to moor in the operating environment, or the maximum load acting on the mooring cable when other smaller ships are moored but a greater load is generated.
The maximum load in the anchor leg with the greatest load when the single point mooring device is moored with the largest ship it is designed to moor in the operating environment; or the maximum load in the leg with the greatest load when other smaller ships are moored but a greater load is generated. Definition and Explanation
A system that can return a sea buoy (ship or floating device) that has deviated from a predetermined position to its original position and continuously maintain it in the predetermined position is generally electronic and mechanical A positioning system that uses power to automatically maintain the pre-position of a floating body (ship or floating equipment) at sea. It is a positioning system that uses power to automatically maintain the pre-position of a floating body (ship or floating equipment) at sea. It is a system that uses power to automatically control the floating body (ship or floating equipment) to detect the displacement of the floating body due to external forces (wind, waves, currents, etc.). After the position detection system detects the displacement of the floating body due to external forces (wind, waves, currents, etc.), the control system issues a control command after the information is processed by the control system, and the thrust system generates a corresponding thrust to eliminate the displacement. The system returns the floating body to its original position. It is a system used to detect the displacement of the floating body (ship or floating equipment) at sea due to external forces such as wind and current. It refers to a system in which the thruster in the dynamic positioning system sends thrust according to the control command to offset the disturbance force. Synonyms not recommended

Meaning or description
Use anchor and pin chain (follow-up) to keep the ship or floating device at sea to limit wind and waves.A method of positioning a vessel or floating device to a predetermined position by using multiple chains (cables) fixed to the seabed and distributed around it. A mooring system that uses multiple mooring buoys to keep a vessel or floating device at sea and keep it at a predetermined position. A mooring system that uses multiple mooring buoys to keep a vessel or floating device at sea and keep it at a predetermined position. The piles used to fix the anchor chains (cables) are driven into the seabed and the negative pressure surface formed by the suction method is pressed into the seabed as an anchor. The hollow cylindrical piles used for sealing points are mainly based on the weight of the pile itself and are able to withstand the displacement of vertical and horizontal loads. They are buried in the seabed soil and rely on the weight and shear strength of the soil to increase the manpower. The definition or definition is to use the system to keep the ship or floating device on the ground. When the dynamically positioned ship or floating device is drilling and operating at sea, its horizontal displacement is controlled within a certain range to ensure the smooth progress of the operation. The radius of the circle is usually determined by the fraction of the water depth. Unrecommended intertributary
