摘要
针对悬链锚腿系泊(CALM)单点系泊系统实例,利用稳定性理论和时域仿真方法进行研究。首先对在风、浪、流作用下的单点系泊(SPM)系统进行动态稳定性分析,并使用时域仿真验证动稳性分析的有效性,接着重点研究何种风浪流组合容易使系统产生鱼尾运动,分析鱼尾运动的危害,提出并验证拖轮协助和油船螺旋桨倒车阻止鱼尾运动的可行性,最后对这2种方法相关参数进行敏感性分析。在实际工程中,通过对遭遇的环境荷载的判断,可以有效地预测鱼尾振荡的可能性,以及时采取可靠措施。
The stability theory and time domain simulation method are used to study catenary anchor leg mooring(CALM)single-point mooring system.Firstly,the dynamic stability of a single point mooring(SPM)system under the action of wind,wave and flow is analyzed,and the effectiveness of dynamic stability analysis is verified by time-domain simulation.Then we focus on which combination of wind and waves and currents is easy to cause fishtailing oscillations.Next,the harm of fishtailing oscillations is analyzed,and two methods to control the fishtailing oscillation,which are a tug boat assisting and a thruster force by stern propeller,are proposed and verified.Finally,the sensitivity analysis of the parameters of these two methods is carried out.In practical engineering,the judgment of the encountered environmental load can effectively predict the possibility of fishtail oscillation and take reliable measures in time,which has a high engineering practical value.
