单锚链系泊以其设备简单、锚系方便、能较好地适应环境因素的变化而广泛适用于开阔水域.但因其自由度大,漂移、偏荡剧烈,按静力计算往往偏于危险,设计时应考虑动力影响因素和采取相应的缓冲措施.本文推导的公式可以较方便地估算出锚链淌航距离S、淌航时间t和t时刻对应的船速V,进而提供了船舶自由漂移全过程的各参数值,并分别从嵌刀止链最短时间和要求满足控制最小安全距离的概念出发求得锚系冲击力,以提供动力稳定性校核的依据.
Single-chain mooring has its advantages of simple equipment and convenient anchor system, and can be widely adapted to open water due to the change of environmental factors.But due to its large degree of freedom, drift and strong swinging, Dangerous, the design should take into account the dynamic factors and take corresponding cushioning measures.The formula derived in this paper can more easily estimate the anchor chain drifting distance S, t and t at the t-time corresponding to the ship speed V, and then provide the ship Free drift of the whole process of the value of each parameter, respectively, from the minimum length of time required to meet the minimum controllaid snap-in and control of the minimum safety distance to obtain the impact force of the anchor to provide the basis for the dynamic stability check.
