This study addresses the critical engineering challenges in the structural design of offshore wind turbine towers, focusing on enhancing resistance to extreme environmental loads. Using finite element analysis (FEA), this research evaluates the effectiveness of various internal stiffener designs—ring stiffeners, skeletal-type stiffeners, and their combinations—in reinforcing cylindrical offshore wind turbine towers against wind and wave forces. These findings have significant implications for the design and construction of mega offshore wind turbines, highlighting the importance of integrating advanced stiffener configurations to improve structural stability in harsh marine environments. offshore wind turbines; wind turbine tower; tower stiffener design; buckling resistance; structural strength analysis.

The proposed work is divided in two parts, i.e. analysis of, tower and connections. To understand exact behavior of connections for proposed loading and boundary condition, FE analysis of two types of connections, flange and friction is carried out using ANSYS. A tubular tower is designed for an IEC class II wind turbine corresponding to most of Indian conditions with variable cross section along the height and variable thickness of shell has taken. 1. Finite Element Analysis (FEA) evaluates flange and friction connections under IEC class II wind turbine conditions. 3. The analyzed wind turbine tower has a height of 80 m and weight of 1586 kN for design purposes.
This investigation applies the finite element method (FEM) to analyze the hydro-aerodynamic behavior of structures under the influence of wind and ocean waves. Wind and wave loads were modeled by using fluid dynamic tool in ANSYS. The structural behavior under such loading conditions was measured by using the analysis static structural tool in ANSYS. The effects of wind velocity and ocean waves on the structural models with varying brace bar diameter and thickness, were measured. Results show that increasing flow velocity from 50 m/s to 60 m/s leads to a rise in impact pressure from 0.0096 MPa to 0.0157 MPa and deformation from 6.7263 mm to 6.9291 mm. Increasing the brace bar diameter and thickness dimensions from 400 mm × 20 mm to 600 mm × 40 mm reduced stress from 96.29 MPa to 80.14 MPa. With the results achieved, when designing the offshore wind turbine power foundation model, it is necessary to consider the recommended dimensions to ensure the structural stability during work.
