dc.description.abstractThis study aims to investigate the challenges and feasibility of extending monopile technology for larger wind turbines and deeper water. Preliminary monopile designs to support the DTU 10 MW reference wind turbine were established for water depths 20 m, 30 m, 40 m and 50 m. To properly account for the pile-soil interaction and the rigid pile behavior of large-diameter piles, lateral soil stiffness was derived using the finite element software Plaxis 3D. To verify the preliminary design, FLS analyses were done using the SIMO-RIFLEX computational tool. As the water depth increases, the contribution of hydrodynamic loads to fatigue damage is found to be larger. A method for predicting total fatigue damage using fewer representative sea states was introduced: a fatigue Damage Parameter (FDP) was established to correlate fatigue damage to environmental condition by means of thrust, significant wave height (Hs) and wave peak period (Tp), and to select representative conditions. Using at least 30% of the total number of conditions resulted in at least 90% accuracy in damage prediction.nb_NO
