Offshore wind turbines are a complex mechanical systems located in severe environmental conditions. The calculation of design loads on offshore wind turbine structures is a complex undertaking involving the integration of different wind and wave load simulation methods. The aim of the thesis is the investigation of influence of the environmental conditions on the aerodynamic and hydrodynamic loads acting on fixed offshore wind turbine structures using in-house boundary element solver panMARE. So the generic NREL 5MW offshore wind turbine with the combine of three different turbines support structure typologies: monopile, tripod and jacket are chosen. Furthermore for verification of BEM results, RANSE simulations are carried out using the ANSYS CFX solver .The results comparison demonstrate the ability of the BEM solver to simulate the aerodynamic and hydrodynamic flow on a complex 3D offshore wind turbine.
