Problems solved by technology
Among them, the traditional soft-rigid boom single-point mooring system is usually a "double-bottle" structure, and the connection end with the mooring head is an A-head structure. When the wind flow suddenly turns to the FPSO's forward rush, the A-head may be crushed , resulting in extreme stretching of the mooring legs or collision of the bow with the ballast tank, resulting in damage to the mooring platform and the mooring ship

The disclosure relates to a buoyancy type single-point mooring system, and relates to the technical field of ships and offshore engineering equipment. The system is used for ship mooring. The buoyancytype single-point mooring system comprises a mooring tower, a buoyancy mechanism, a mooring leg and a mooring arm. The mooring tower is fixedly and vertically arranged on the sea floor and exposed above the water surface, and the buoyancy mechanism floats on the water surface and is located between the mooring tower and a ship. The two ends of the mooring leg are rotatably connected to the ship and the buoyancy mechanism separately, one end of the mooring arm is connected to the buoyancy mechanism, and the other end of the mooring arm is rotatably connected to the mooring tower. On the one hand, the ship displacement is effectively reduced, and the crushing phenomenon is avoided so as to avoid collision and damage of the mooring system or the ship; and on the other hand, the buoyancy mechanism is used for converting the buoyancy into resilience, the construction, maintenance and repair costs are reduced without the need for additionally arranging dampers. In addition, a buoyancy tankcan be used as the buoyancy mechanism, and a large amount of oil, gas and water can be stored in the buoyancy tank to enable the buoyancy tank to be as an offshore fuel supply station.
Description
technical field [0001] The present disclosure relates to the technical field of ships and marine engineering equipment, in particular to a buoyancy single point mooring system. Background technique [0002] Oil is the blood that drives economic development. In recent years, 60% of newly discovered oil and gas fields are located offshore, and there is a tendency to concentrate in deep sea areas. The mooring system is a "floating terminal" that can be used for crude oil loading and unloading by offshore tankers such as FPSO (Floating Production Storage and Offloading) without docking at the terminal. Compared with the traditional fixed crude oil terminal, the mooring system has the advantages of large crude oil loading and unloading capacity, low construction investment, short construction period, and less affected by climate. [0003] Mooring systems usually include multi-point mooring systems and single-point mooring systems, and multi-point mooring systems are more suitabl...
