AB - Many countries, including the EU member states and the US, have legislated a transition from traditional fuels torenewable energy sources, with offshore wind power expected to play a key role in this shift. Given that foundation type accounts for approximately 30% of the total cost, their selection and installation are crucial decisions. Monopiles are currently the most commonlyused foundation type, representing about 80% of existing Offshore Wind Turbines (OWT) foundations. However, installing them significantly disturbs the seabed and presents difficulties in deeper waters, increasing interest in alternative foundation solutions. This study examines helical piles as a more economical and lower-footprint option compared to conventional piles. Their response in sand under monotonic lateral loading is investigated through advanced three-dimensional numerical analyses employing state-of-the-art constitutive models and special interface elements. A bespoke script extracts p-y curves from the three-dimensional analysis. A series of parametric analyses were performed to examine the influence of the number and location of helices and to develop designrecommendations for optimized OWT foundations. The analyses consider three relative densities (Dr) of Dunkirk sand.
