深海锚泊浮标的二阶动力分析

Second-order dynamic analysis of a moored deep ocean buoy

计算了规则波上深海锚泊浮标的运动响应和锚泊线的动力响应。在对浮标的二阶漂移力计算时考虑了锚系的影响 ,并将浮标平均漂移的计算结果与不考虑锚系影响的结果进行了比较。本文计算所用浮标为单点系泊浮标 ,锚链由不同重量的分段组成。

The motion respo nse of a moored deep ocean buoy and the dynamic response of the mooring line in regular waves are calculated numerically in this paper. In a previous model test of a moored buoy in waves, the drift of the buoy was not consistent well with t he drift obtained numerically. The reaso n may be the effect of the mooring system , which was not taken into consideratio n in the calculation of the second order w ave drift force. In this paper, the effe ct of the mooring system is considered in the calculation of the second order wave drift force, and the two numerical resu l ts are compared. The comparison shows t he improvem ent of the result. The buoy mentioned in this paper is a one-point moored buoy. T he mooring line consists of different se gments of weight.
