The five-connected bucket foundation is an innovative modification of the composite bucket foundation
proposed to address the complex marine conditions near Hainan Island and the demand for wind turbines with a capacity of over 15 MW. It has been optimized in terms of load transfer mode
allowable pressure difference
and self-floating stability
enhancing its adaptability to deep-water and large-capacity wind turbines. Based on a project in Hainan
and considering the structural characteristics of the five-connected bucket foundation and the potential issue of the skirt not settling properly
a 1∶80 scale model was selected according to the principle of similarity. Model tests were designed with different incoming flow angles and skirt exposure heights as variable conditions to study the local scour characteristics of this new type of offshore wind foundation. The experimental results include the history curves of local scour depth under different flow angles and skirt exposure heights
the local topography after scour equilibrium
and the shape and size of the scour pit. The study clarifies the local scour characteristics of the five-connected bucket foundation under unidirectional flow and analyzes the impact of skirt exposure on the scour results.
