摘要: 移动式海洋结构物定位的主要方式是用锚链系泊定位,要了解海洋结构物的运动响应、动力特性等,必须知道锚链的弹性系数.本文给出了锚链弹性系数的定义.从锚链悬链线方程着手,推导出了系泊移动式海洋结构物(主要是移动式海洋石油钻井、采油平台)用锚链的弹性系数的数学表达式.最后,分两种情况进行了讨论,给出了简化条件下锚链弹性系数的数学表达式.

Abstract: The main way to position movable offshore structures is to moor them with mooringlines. To determine the motion response,dynamic behavior of the movable offshore structures,etc.the elastic coefficient of mooring lines must be known.The definition of the eJastic coefficient of a mooring line is given.Beginning with the equation of a catenary,the mathe-matical expression of the elastic coefficient of mooring lines is derived,which is used formooring movable offshore structures(especially movable offshore drilling and productionplatforms).Finally,a discussion is made under two special conditions. A simplified mathe-matical expressions of elastic coefficient of mooring lines are given.
