Computational framework for mechanical integrity assessment of offshore wind turbines


School of Engineering

About the Project

The offshore wind turbines are subjected to various wind and tidal loads which can result into earlier than expected fatigue of their components. Different parts of the wind turbines are manufactured from a variety of materials that have different fatigue lives. The welded steel tower structure is either fixed or floating type. The metallic nacelle and rotor structure are mounted on top of the welded steel tower whereas the fibre-reinforced composite based turbine blades rotate due to the passing wind which then rotate the main rotor shaft and thus the coils that generate electric current.

The aim of this research is to develop a comprehensive computational framework that can be employed to establish the soundness of the structural integrity of the wind turbine and also establish the fatigue life.

The main objectives are to:

• Established an integrated FE model of wind turbine structures including rotor, nacelle, tubular tower and foundation
• Develop a wind-induced response model of wind turbine structures with different speeds and directions
• Establish verification methodology to determine the accuracy of the proposed wind-induced response model by comparison with the existing field test data
• Assess the impact of low stress range, wind direction and the blade rotating effect on the fatigue damage
• Establish the best in class method to conduct the fatigue analysis

Candidates should have (or expect to achieve) the UK honours degree at 2.1 or above (or equivalent) in Mechanical or Civil Engineering. It is essential that the applicant has an Engineering or Applied physics background with knowledge of CAD and FE based modelling along with knowledge of structural mechanics and an understanding of theoretical foundations finite element analysis.
