摘要

为提高OC4风力机平台在风浪流联合作用下的稳定性和安全性

将多段式系泊与OC4平台原系泊系统相结合

建立不同重块和浮块配置的系泊系统

采用FAST to AQWA（F2A）计算

比较了4种不同系泊系统对OC4风力机平台运动响应的影响

并基于T-N（应力幅值-应力循环次数）曲线对其系泊系统疲劳损伤进行分析。结果表明

相比于原系泊

单重块系泊系统对浮式风力机平台运动响应和低频共振响应有着较好的抑制作用

但会略微增加波频的共振响应;单浮块系泊系统能明显降低系泊张力;多段式系泊展现出良好的抗疲劳性。

Abstract

In recent years

with the widespread application of semi-submersible platforms in offshore engineering

there have been numerous innovations in the mooring systems. Among these

the multi-segmented mooring system has demonstrated good effectiveness in reducing platform dynamic responses. To improve the stability and safety of the OC4 offshore wind turbine under the combined action of wind

waves

and currents

a mooring system combining the multi-segmented mooring with the original OC4 platform mooring system was established

with different configurations of weights and buoys. Using the FAST to AQWA （F2A） to investigate the motion response of the OC4 wind turbine platform with four different mooring systems

and the fatigue damage of the mooring system was analyzed based on - curves. The results show that compared to the original mooring system

the clump weight mooring system has better suppression of the motion response and low-frequency resonance response of the floating wind turbine platform

but it slightly increases the wave-frequency resonance response; The buoy mooring system can significantly reduce mooring tension and the multi-segmented mooring system demonstrates good fatigue resistance. The numerical simulation results of the multi-segmented mooring system provide scientific reference for the development of mooring systems for floating offshore wind turbines.
