摘　　要：针对波浪能发电平台布置海域水深浅、台风多发、珊瑚礁地质地基承载力低的特点,以“南鲲号”鹰式波浪能平台为研究对象开展低载荷浅水锚泊系统方案设计和动力学分析研究。通过对全锚链、弹性索与弹性索+浮筒3种不同方案的对比研究发现:相较于全锚链系泊方案,高弹性非线性材料的添加可有效降低系泊张力、起锚力与水平载荷,但会增大平台运动范围;弹性材料与浮筒的联合应用则可在进一步降低系泊系统载荷的同时,限制平台运动范围。在满足经济安全需求基础上,弹性索+浮筒系泊方案在适应浅水恶劣环境方面有着良好预期。In China,most of the wave energy converter(WEC)is located at shallow water where the coral reef seabed cannot withstand excessive loads.To survival in frequent typhoon,design methods and dynamic analysis on the mooring system of“Nankun”WEC are studied.In the paper,three kinds of mooring lines is surveyed,which include the case of catenary,catenary+elastic cable,catenary+pontoon+elastic cable.Comparative studies show that:compared with the catenary case,elastic cable can reduce the mooring tension and increase the horizontal displacement of WEC,elastic cable+pontoon can further reduce the mooring tension and reduce horizontal displacement of WEC.Theoretically,The catenary+pontoon+elastic cable is the best solution of mooring system of WECs n adapting to the harsh environment of shallow water.
