Abstract

This study investigates the discrepancies in local scour development across different model scales using numerical simulations. Field data from offshore wind farms in Jiangsu （China）, the North Sea （Europe）, and Guangdong （China） are incorporated to establish full-scale numerical models, ensuring realistic hydrodynamic and sediment transport conditions. A key innovation of this work is the introduction of an average Reynolds number （Rea） to characterize scale-independent scour processes, leading to a new predictive formula for monopile scour depth under field conditions. Furthermore, the study examines the impact of the relative exposed bed height （e/D） and ware-current conditions on scour depth for single bucket foundations, with a dedicated formula proposed for the latter based on numerical results.

Key words

offshore wind power / scour / monopile foundation / single bucket foundation / scale effect / Reynolds number / numerical simulation
