Shared mooring systems for offshore floating wind farms: A review

Floating wind farms are a type of offshore wind power generation system that uses an array of wind turbines on floating platforms instead of fixed foundations rooted to the seabed [17]. In addition to the turbine, an individual FOWT primarily comprises three major marine components: a floating platform, mooring lines, and mooring anchors.
