Experimental study of bed solidification as a local scour countermeasure for offshore wind turbine monopile foundations

Bed solidification methods are widely employed for mitigating local scour. This study primarily examines the geometric aspects that influence bed solidification protections, including protection thickness, angle, lateral extent, and placement depth. Scour topography and longitudinal scour profile across various test conditions have also been discussed. Additionally, a schematic discussion of the interaction between flow patterns corresponding to different protection shapes and their resulting scour patterns are presented. The influences of different geometric aspects on equilibrium scour depth have also been studied. Furthermore, an integrated approach combining riprap and bed solidification protection methods has been examined experimentally.
