Chair's Opening Remarks 

Advancements In Blade Inspection Methods To Reduce Overall Downtime


Panel: What Should A Good Blade Inspection Program Look Like To Reduce Excess Future Expenditure?

  • What kind of inspections do most wind farms require and how does yours differ?
  • Depending on the wind farm, location, weather conditions, age and blade materials which part of the blade needs the most attention?
  • Given the variables is it better to keep in house or outsource inspection work?
  • How is it best to deal with the data gleaned from inspections and how should you respond to damage and the need for upkeep ?
  • What future innovations do we see becoming standard and how can they assist in O&M of Blades e.g. infrared technology and automation  

Carsten Westergaard, Senior Adviser, Sandia

Daniel Molyneux, Blades Manager, Vestas

Jian Lahir, Blade Engineer, EDPR


How To Better Utilise Drones And The Data Captured During Inspection

  • Collecting the right data during drone inspection
  • What is done with the data once it is collected and is there a measured improvement in data quality in using drones?
  • How does this improve LCOE?
  • Why there is need for the right people with correct experience providing reports on drone findings

Networking Break And Morning Refreshments 


Let The Blade Data Talk!

  • Collecting and structuring blade data: how do you aggregate blade inspection and repair data coming from different suppliers?
  • Analyze and observe the data: how do you measure te quality of the inspection images you receive? What defects do you have on your blades? How do you make efficient O&M blade decisions thanks to data?
  • Leverage your blade data: how machine learnings makes your life easier

Thibault Gouache, CEO, Cornis


Reducing Down Time Using A Combination Of Inspection Methods

  • What is the payoff using a combination of inspections?
  • Where are drones, ground-based cameras, rope access and on-site technicians best utilised?
  • Optimising various methods of inspection for an efficient O&M program
  • What is the value proposition for each inspection method?

Daniel Molyneux, Blades Manager, Vestas


R&D Demonstrations Of Ground Based Inspection And Monitoring Using The Sabre System

  • How the digital wind sabre system works
  • An update on the field applications of technology and results gained so far
  • Perspectives on implementation of longer term blade inspection programs

John T Lindberg, Program Manager - NDE Innovation, Electric Power Research Institute


Networking Lunch

Assessing Various Types Of Damages, Their Affect On Performance And Best Practice For Repair


Structural Enhancement Technologies For Blades - Reduced O&M Cost And Risk

  • Avoid damages and reduce your risk
  • Reduce O&M cost for blades utilising innovate solutions
  • Remove that root cause for damage and secure the lifetime of the blade
  • Case study and test: D-StiffenerTM 

Ryan Hagelskjaer Lauridsen, CEO, Bladena


Case Study: Managing Lightning Damage And Taking Suitable Precautions

  • Best work practices around detecting lightning strikes
  • What weather data, is being used to predict strikes and model weather conditions?
  • What sensors are currently being used and do they help?
  • Are carbon blades more prone to lightning damage and what can be done to avoid this?
  • Challenges involved and experience required for repairing lightning damage

Addressing Extreme Weather Conditions And Exploring Icing Technology

  • Why the big issue: How does icing affect the flow dynamics and power curve?
  • Worst case scenarios, impact damage from ice break-offs and dealing with transverse cracks
  • What protection methods are currently available and do chemical coatings work?
  • De-icing & heated blades
  • Long term solution to an ongoing challenge
  • Loads on blades and ice accretion prevention

Understanding The Different Repair Methods Required For Each Blade Type

  • Correctly evaluating which repairs are needed
  • How to repair spa damage for both carbon and fibreglass blades
  • Differences in approach to maintenance on different blade and composite structures
  • Using similar repair materials to avoid increasing stresses on the blade
  • Ensuring quality in your repair service and taking good advice when it's needed and not focusing on cost

Networking Break And Afternoon Refreshments


Speed Networking

Realising the importance of connecting with your peers, we organised a moderated networking session where delegates are prompted to meet others in brief 3/4 minute rounds. The moderator will be keeping track of time and announcing participants when to switch partners,

Make sure you bring lots of business cards along with you!


Topical Roundtables And Drinks

Delegates will select one of the following peer-to-peer discussions from the strategic or technical streams listed below. You will need to move into small break-out groups where discussions will be off the record and led by an expert on the given topic.  The discussions will be informal and open with drinks served whilst they take place.

Delegates are encouraged to bring along their considered ideas and questions in order to facilitate a meaningful and in-depth discussion whilst keeping with the relaxed tone.


A. The Need For Real Data Standardization On Blade Damages

B. Why Is Dependency On Manufactures Holding Back Advancement?

C. What Can Be Learnt From The Aerospace Industry?

D. How Will Consolidation Of Supply Chains Affect Asset Management for Blades


A. How Best Can The Industry Create A Collective Standard On Blade Quality?

B. How To Prove The Benefits Of A Repair And Retrofit On Power Performance

C. Brainstorm: What Could Condition Monitoring For Blades Look Like?

D. What Are The Parameters For Qualifying A Good Repair?


Roundtable Feedback

Delegate return to the main plenary room to hear the discussion leaders sharing the main outcomes of the sessions
