Abstract
Several methodologies to predict the static soil resistance to driving (SRD) available in the literature have found wide
use in the offshore industry over the last decades. These range from simple methods that require few soil strength
parameters to more advanced semi-empirical methods that correlate the driving resistance to cone penetration test
measurements. These methods were primarily developed based on driving records for piles less than 2.5m in diameter
i.e. much smaller than the monopiles currently used in the offshore wind industry today. The aim of this study is to
evaluate the accuracy of some of the most widely used SRD prediction methods when employed for driveability
analysis of large diameter monopile foundations, by comparing the predicted SRD profiles with the driving records of
6.5m diameter monopiles installed in the Danish region of the North Sea.
