This paper presents a methodology for the application of erosion test results for scour prediction. Erosion tests on field samples were performed to understand the erodibility and erosion rates of the soil samples. The soil characteristics that affect susceptibility to erosion include: Particle Size Distribution (D50) and Fines Content. These are employed alongside the normalised Soil Behaviour Type (SBTn) expressed by the index Ic, derived from Cone Penetration Tests (CPT), correlated to the erosion test results, to define parameters where the onset of erosion is observed. Threshold values of the D50, Fines Content, percentage of clay and the Ic values are determined based on the erosion test results to inform the likelihood of scour occurrence in-field. These threshold parameters were then assigned weight factors based on their criticality and applied on soil samples acquired from a field in the North Sea to assess the likelihood of scour susceptibility and its duration. Based on the results, a risk-based approach was developed and implemented to plan and deploy scour protection around the foundations of an Offshore Wind Farm in the North Sea following foundation installation.
