浮式风机浅水系泊松弛-张紧特性

Slack-Taut Characteristics of Mooring System for Floating Wind Turbine in Shallow Water

以10 MW浮式风机的系泊系统为研究对象,分析不同工况、不同系泊参数下系泊缆张力和风机运动响应变化规律,探讨系泊缆松弛-张紧现象产生的原因,分析不同系泊参数对系泊缆极限张力的影响。结果表明:提高导缆孔高度、在系泊缆上增加质量块和浮筒均可有效消除系泊缆松弛状态,减小系泊极限张力,保证系泊安全。

Taken the mooring system of a 10 MW floating wind turbines as the research object,the mooring line tension and floater motion under different working conditions and mooring parameters are investigated.The causes of the slack-taut phenomenon of the mooring line as well as the influence of mooring parameters on the mooring property are studied.The results show that increasing the height of the fairlead and adding clumps or buoys on mooring lines can effectively eliminate the slack state of the mooring,reduce the ultimate tension of the mooring line and ensure the safety of the mooring system.
