Background
Mooring safety influence factors are quite complex, and the influence of natural conditions such as wind, waves, currents and other external natural conditions is also influenced by parameters of ships, docks, mooring forms and the like. Under certain conditions of the wharf and the ship, mooring ropes and external environmental conditions play a decisive role in mooring safety. Under the action of certain wave conditions, the motion amount variation amplitude of certain degrees of freedom of the ship is very large, so that the cable can be loosened and tensioned repeatedly and alternately, the cable force among the cables is very uneven, and high impact tension is easily generated, so that the cable is fatigued, and the risk of cable breakage is caused.
Some ports at home and abroad have cable breakage accidents for many times, and the operation and safety of the wharf are seriously influenced. As a means for improving the mooring condition of the ship in the long-period water area, the constant-tension mooring system not only can reduce the shaking of the ship body, so that the ship is more stable during operation and the operation efficiency is improved, but also can improve the operation condition and increase the allowed operation days under the current standard by improving the shaking degree of the ship body. As a novel mooring and sway reduction means applied to a long-period water area, the constant tension mooring system can well improve the existing wharf, has the characteristics of relatively low improvement cost investment and environmental protection, and has wide prospects in wharf operation of long-period wave water areas.
The existing constant tension mooring system is mostly a mooring winch, constant tension is kept unchanged by slowly winding and unwinding a rope, the constant tension mooring system is effective in keeping constant tension during small-amplitude movement, but the structure has small influence on the inherent period of a coupling system formed by the mooring system and a floating body, and the mooring winch is mostly applied to the processes of hoisting operation and the like.
