In this study, Integrity evaluation of offshore wind turbine substructure was carried out. The strain values obtained by strain gauges circularly installed on upper part of the substructure was converted into vertical and moment load. Considering directions of the moment load through FEM, the most conservative P-M interaction diagram of the model was graphed. Obtained load values were evaluated by utilizing P-M interaction diagram.
