Investigation into a new CPT-based design method for large diameter monopiles in sand

The API RP 2GEO (2011) p-y method is an industry standard approach to predict the lateral pile behaviour of slender oil platform piles with length (L) over diameter (D) ratios > 10. However, offshore wind turbines are founded on large diameter monopiles with an L/D ratio < 8, which are rather rigid piles. There are concerns about the...
