This study presents the shape sensing of a blade of the NREL 5 MW offshore wind turbine using the inverse Finite Element Method (iFEM) under real loading conditions. Aerodynamic forces are calculated based on the Blade Element Momentum Theory (BEMT). The accuracy of the iFEM analysis is tested by comparing the results with full sensors and reduced sensors to the reference Finite Element Method (FEM) analysis. Practical distribution of iFEM elements with sensors is explored and the effects of different wind velocities are investigated for more practical analysis. Based on numerical results, it is concluded that iFEM is a suitable technique for shape sensing of offshore wind turbines.
