Blade Operations And Maintenance Forum

Pre-Forum Focus Session - Tuesday 19 September 2017

Quality Assurance And Testing Of Blade Structure, Manufacture And Design


Chair's Opening Remarks 

Carsten Westergaard,  Senior Adviser Sandia


How Service Requirements Are Shaping Blade Manufacture And Design And Why Are Certain Materials Used?

  • What is the industry doing in this area and what are the latest techniques being used?

  • Identification of service requirements, how they are changing?

  • How does this translate into adaptation of product design and production methods used?

  • Material selection for erosion protection and other wear and tear damages – the service perspective

  • Is there feedback and data being used from the field to inform the latest designs, if so, how?

  • Technical Improvements that contribute to a lower cost of energy

Improving Blade Testing To Decrease Faults And Increase Lifetime Longevity

  • What testing is currently being used and what is holding back industry standards being implements?

  • How should we test for various weather conditions, lifespan longevity and inconsistencies in manufacturing?
  • Should different blade types require different O&M approaches or is there room for a 'one fits all' method
  • How to tell a good blade from a bad blade
  • Testing the blades for the particular regional conditions in which they will be exposed to

Networking Break And Afternoon Refreshments


Open Fishbowl Discussion: What Constitutes A High-Level Quality Assurance Process In The Manufacture And Production Of Blades

Three to four chairs are arranged in an inner circle. This is the fishbowl. One chair is left empty. The moderator introduces the topic and the participants start discussing the topic. The audience outside the fishbowl listen in on the discussion.
Any member of the audience can, at any time, occupy the empty chair and join the fishbowl. When this happens, an existing member of the fishbowl must voluntarily leave the fishbowl and free a chair.
The moderator will instigate a set of rules during the fishbowl to ensure an open and friendly discussion takes place

  • Are common damage and erosion issues being taken into consideration in the manufacturing stage?
  • What are the benefits of different blade models and how best can older blades be repurposed?
  • Is there scalable research that can be applied to full-scale turbines and wind farms?
  • The need for having blade quality assurance practices in the manufacturing stage
  • Using optimal recognition software in screen blades being made
  • Creating real certification and quality assurance through transparency in manufacturing processes
  • The need for better warranties for LEE and lightning damage
