Offshore wind farm lifetime extensions: why the ‘beyond 2020’ energy policy dialogue must start now

20 Nov 2014

Offshore wind, which is rapidly evolving and scaling in response to harsh environments, makes repowering a complex decision, especially without energy policies and incentives set in place.

Engineers design turbines for a specific lifespan and have to prove that components will not fail within that time. The agreed 20-year design lifetime means engineers can design to meet one consistent requirement, ensuring that new components can be guaranteed to work reliably and be insured for that period.

What should wind farm operators do when that lifetime is up?
