系泊断裂情况下15 MW漂浮式风力机平台动态响应影响
Investigation on the impact of dynamic response of a 15 MW floating offshore wind turbine under mooring breakage
摘要
Abstract
This paper focuses on the wind turbine,semi-submersible platform and mooring system.In order to study the dynamic response generated by mooring breakage,this paper analyzes the platform motion response and mooring maximum tension of two different redundant mooring systems with IEA 15MW wind turbine and the Umaine VolturnUS-S semi-submersible platform based on the OpenFAST and AQWA(OpenF2A).The results indicate that after mooring breakage,the platform experiences increased surge and sway,with relatively minor impacts on nacelle vibrations and tower base loads.Meanwhile,the tension in the adjacent moorings increases sharply but remains well below the ultimate breaking strength,keeping the mooring system in a relatively safe condition.The transient changes in mooring tension at the moment of mooring breakage were studied,revealing that the transient effects are less severe in the three-mooring system compared to the two-mooring system.In summary,the simulation results indicate that under the combined action of wind,wave,and current,the three-mooring system is more stable than the two-mooring system.It effectively reduces platform displacement and increases in mooring tension,thereby enhancing the redundancy of the mooring system.关键词
