Problems solved by technology

The dynamic response characteristics of the shallow water tension mooring determine that the shallow water mooring system cannot simply adopt the small radius tension mooring system if it is used as a long-term mooring and has to withstand large sea conditions.

Abstract

The invention relates to the technical field of water mooring, in particular to a mooring system which comprises a mooring cable, wherein one end of the mooring cable is connected with an anchor point at the water bottom, and the other end of the mooring cable is used for being connected with a floating structure on the water surface; the mooring cable is provided with at least one buoy and at least two balancing weights, wherein the balancing weights and the buoys are arranged in the length direction of the mooring cable at intervals, and at least one balancing weight is arranged on each of the two sides of each buoy. A combined structure in the form of balancing weight-buoy-balancing weight is arranged on the mooring rope, so that the mooring system forms the capability of restraining the floating structure from shifting in the horizontal direction, and meanwhile, the mooring system has enough flexibility and small overall rigidity, which is equivalent to adding a low-rigidity shockproof buffering device in the middle of the mooring system, so that the dynamic tension amplitude brought by wave frequency excitation in the mooring cable can be reduced by one to two orders of magnitude, the use length of the mooring cable is greatly reduced, the tension grade of the mooring cable can also be reduced by one order of magnitude, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mooring on water, in particular to a mooring system. Background technique [0002] Floating structures are subjected to external loads such as wind, waves, and currents at sea, and a corresponding mooring system is required to connect them to the seabed to ensure that they are moored near the target position and will not be washed away by wind, waves, and currents. Run or blow away. Common mooring systems The forms of mooring systems are different according to the target water depth. According to the relative proportional relationship between the size of the floating structure and the water depth, the mooring system can be divided into deep water mooring and shallow water mooring. Record the projected outer contour area of ​​the underwater part of the floating structure on the horizontal plane as S, and define the characteristic scale of the outer contour of the floating structure Note that the wavele...
