Offshore steel wind turbines (OWT) are a popular choice for generating renewable energy due to higher offshore wind speeds leading to significantly increasing amount of produced energy. Offshore steel wind turbines are susceptible to vibration problems considering persistent wind and wave forces. This can lead to reduced performance and even failure. The traditional support of wind turbines is the use of tubular steel sections characterized by low stiffness and damping leading to excessive vibrations. Many vibration control practices are available including the use of tuned-type dampers, e.g., mass dampers, and magnetorheological dampers. However, their use is challenged by deformation limits which lessens damper stroke and damping effect. This paper investigates and numerically evaluates current applications to reduce vibration problems. Focus is given to areas in Saudi Arabia that can lead to highest energy harvest. The finite element method is employed to simulate an example offshore steel wind turbine structure considering common damping techniques. The study is intended to provide necessary theoretical base for guidelines to efficient design of OWT structures. Results showed a reduction in displacement reaching 95.5% when using Tuned mass dampers.
