一种组合系泊系统及其系泊特性影响研究

摘要

To further reduce the motion of floating body, a combination mooring system is selected in application. Based on the 3-D potential theory, the motion of a moored floating body is calculat-ed by using AQWA software. And the mooring system is composed of chain, clump, elastic cables and combination of them. By comparing the floating body response and tension in fairlead, this pa-per finds that the motion and tension are reduced largely when the mooring system contains elastic cables. The motion and mooring line tension decrease further when the length of elastic cable in-creases but the position of the elastic cable makes no difference to the motion and the tension. In addition, the motion reduces when the mooring system contains clump, but the tension increases a little, which has very important significance in practice.%为了在较低的成本下更大程度地减小浮体的运动，文章提出了一种组合系泊系统的概念，并基于三维势流理论，当系泊形式为锚链、重块、弹性索以及它们之间的组合时，运用AQWA软件计算了系泊浮体在不规则波中的运动响应。在几种不同的工况下，通过比较浮体的响应和锚线张力，发现有弹性索时浮体运动和张力明显减小，当弹性索长度增加时，运动和张力减小得更多。当弹性索长度一定时，位置的变化对浮体运动和锚链张力响应不大。带沉子时浮体运动减小，同时锚链张力增加得也不多，文中的发现在工程使用中具有很重要的参考和借鉴意义。
