Mooring Line Failure Analysis of a Novel Grand Trine Shared Mooring System for Floating Wind Farms

To underline the safety redundancy of the novel shared mooring system for floating wind farms, this paper performs a series of mooring line failure analyses including a 2-line failure scenario for a 3-FOWT grand trine shared mooring floating wind farm under 50-year storm conditions. The results indicate each FOWT is sensitive to the failure of upstream mooring lines, causing a transient offset of over 40 m, while the other FOWTs are slightly affected. The fairlead tensions of upstream mooring lines are sensitive to the failure of adjacent upstream mooring lines, while the shared mooring lines are less affected.
