摘要

Floating offshore wind turbines (FOWT) are mounted on buoyant foundations held in position by moorings, enabling deployment well beyond the 60 m depth range of bottom-fixed designs. In the Red Sea—where steep bathymetry quickly exceeds tens and hundreds of meters—this configuration unlocks areas that are inaccessible to fixed foundations. Here, we present a geospatial screening tailored to Saudi Arabia’s Red Sea, combining GIS layers and multi-criteria weighting to delineate technically suitable zones considering wind resource, depth, navigation corridors, and national maritime limits. Across the two most suitable clusters, we estimate about 32–57 GW of installable capacity and ~ 98–174 TWh/y of gross energy, depending on array density, capacity factor, and loss assumptions.
