A study on load evaluation and analysis for foundation of the offshore wind turbine system

With growing of wind turbine industry, offshore wind turbine system is getting more attention in recent years. Foundation of the offshore wind turbine plays a key role in stability of whole system. In this work, 5MW NREL reference wind turbine with rated speed of 11.4m/s is used for load calculation. Wind loads and wave loads are evaluated using GH-Bladed (Garard Hassan) and FAST (NREL). Additionally, FE simulation is carried out to investigate the wave effect on the support structure. Meanwhile, this work is trying to systematize and optimize load cases simulation for foundation of wind turbine system.
