Global performance analyses determine the global effects of environmental conditions and other loads on the Floating Offshore Wind Turbine (FOWT) and its components including the tower, floating substructure, mooring lines or tendons, anchors, power cable, etc. Global performance analyses should be conducted for all critical conditions in the pre-service and in-service phases, represented by the design load conditions specified in Part 2. Because significant interactions could occur among the Rotor-Nacelle Assembly (RNA) and control system, the tower, the floating substructure, and the station keeping system, an integrated (“coupled”) model including all these components is recommended to be used for global performance analyses.
