摘要
系泊船舶的离泊波浪标准是保证船舶系泊安全的重要参数,尤其是在较长周期波浪作用下,系泊船舶安全是需要关注的重要问题之一。本文对不同吨位油船、LNG船和散货船进行了较长周期波浪作用下的系泊试验研究,分析了船舶缆绳拉力随波浪周期的变化规律,提出了用以估算缆绳最大拉力的经验计算公式,并结合相关规范要求,给出了较长周期波浪作用时离泊波高随周期变化的折减系数。研究成果可以为实际工程设计提供参考。
The wave standard for ship unberthing is an important parameter,which ensures the mooring safety of ships.In view of the action of long periodic waves,safe mooring is one of the important issues that need to be focused on.In the case,the mooring tests were carried out for oil tankers,LNG tankers and bulk carriers with different tonnage under long periodic waves.The change rule of ship cable tension force along with the change of periodic waves was analyzed.The empirical formula for calculating the maximum value of the cable tension force were put forward.Based the related specifications,the reduction coefficients for the variation of ship unberthing wave height along with the period change were given under the action of long periodic waves.The research results could provide a reference for real engineering design.
