Quotation for your TeamAbout the course
Offshore wind turbines operate in a harsh environment where maintenance and inspection are costly and time consuming. The corrosion and fatigue of the structure consequently represent a major challenge for both the design, and Operation and Maintenance.
In this training course participants will be taken through the techniques used in the design and maintenance of offshore wind turbines, such as fatigue design, fracture mechanics-based inspection, and defect assessment. Additionally, the impact of residual stress effects on predicting the component life will be explained. In doing this, the participants will receive a comprehensive overview of structural integrity as applied to offshore wind turbine foundations.
The course consists of 6hr of live sessions with the instructor. All training content is provided through your EngineeringTrainer account.
