That seems like a relatively old study now. I think blade design and manufacture has developed rapidly. Here is a short piece on the testing of much larger modern blades designed to last at least 25 years offshore [1]

- Retric 7y agoThis article is about blades that are actually 25 years old and being replaced. The video is testing is to ensure new blades can handle both peak stresses in the static test and less stressful cyclical loading for 25 years. So, 25 years from now those blades will also reach the end of their service life and need to be replaced. That said monitoring and inspection can maximize the lifespan of individual turbines even if nobody is aiming for 50+ year service life.
- strainer 7y agoI'm not suggesting they could be expected to last beyond their design. Just when this is the state of blades being built in unprecedented number today, a twelve year old review of much smaller ones made 35 years ago could easily be largely outdated.
