长周期波浪影响下连片式码头系泊布置优化

为改善长周期波浪影响下连片式码头的泊稳条件,结合工程实例,利用数值分析软件分析长周期波浪作用下连片式码头系泊船舶的缆绳张力、船舶运动量特点,提出改善长周期波浪影响下泊位系泊稳定性的关键因素。结果表明,随着波周期的增大,系泊船舶的缆绳张力、船舶运动量均会显著增大;系泊优化的关键在于增加系泊体系的弹性以便吸收船舶的动能量。系泊优化措施包括增加缆绳长度、采用非刚性缆绳系泊或增加缆绳的尼龙尾缆长度。采取系泊优化措施后,可大幅降低长周期波浪作用下缆绳张力,达到系泊布置优化目的。

Mooring layout optimization of continuous wharf under influence of long period wave

In order to improve the berthing stability condition of continuous wharf under the influence of long period wave,combined with an engineering project,this paper analyzes the characteristics of the line tension and the movement of the ships moored by the continuous wharfs under the influence of long-period waves by using the numerical analysis software, and puts forward the key factors to improve the berthing stability under the influence of long-period waves. The results show that the mooring lines tension force and moored ships movements will increase significantly as the period of the wave increases,and the key of mooring optimization is to improve the elasticity of the mooring system so as to absorb the motion energy of the ships. The mooring optimization measures include adding the mooring line’s length,using the non-rigid mooring line or increasing the nylon tail’s length.After the mooring optimization measures being adopted,the mooring lines tension force can be reduced significantly under the influence of long period wave and the purpose of mooring layout optimization can be achieved.
