摘要
从减轻船总体负担、采用链径更小的海洋系泊链的设计需求出发,以单个链环为微元对锚链在锚泊状态所形成悬链线方程进行推导,建立锚链在典型锚泊状态下的悬链线方程,并以此为基础完成不同链径锚链在抛锚长度、最大可承受环境力、最大抛锚深度等方面的计算分析。结合计算结果和船舶实际使用情况,对采用不同链径锚链的锚泊能力进行综合分析后认为,虽然链径较粗的锚链的理论锚泊能力较强,但若采用霍尔锚等非大抓力锚,或对锚泊水域面积无明确要求、没有在深水中抛锚的特殊需求等,则可以选用链径相对较细的海洋系泊链代替目前规范中规定的电焊锚链。
In order to meet the demand of anchor system using thinner anchor chains,this paper deduces the catenary equation by taking every anchor chain link as an infinitesimal. Based on the equation,the length of anchor chains and the maximum environmental forces and water depth are calculated for anchor chains with different diameters. According to the calculation result and actual practices,it is concluded that though the thicker the anchor chain,the better the anchoring capability,the applications of thinner chains are more reasonable when not using anchors with high holding power,or when the situation does not demand any special request of the mooring region or water depth.
