Lifetime Extension: Methodology Development And Implementation For Wind Turbine Drivetrains

More and more wind turbines are reaching the end of their designed service life. Due to economic factors, it is in the operator's interest to keep their wind turbines operating beyond their designed service life, as long as the safe operational requirements are met. This process is known as lifetime extension. Whilst relatively well-established practices exist for the lifetime extension of the structural members, the electro-mechanical and drivetrain are often overlooked. Therefore, this PhD will look at developing a methodology, analysis tools and the framework for the lifetime extension of the wind turbine drivetrains.
