Access And Inspection Methods To Reduce Blade Downtime And Enhance AEP

09:40 

Keynote: Exploring The Most Effective Strategies In Performing Inspections At Lower Costs 

  • What are the costs involved when inspecting blades and how are such costs mitigated internally?
  • Determining how often the blade should be inspected
  • Inspection methods for the location of fatigue load damages
  • Promptly locating where the damage occurred, in order to reduce turbine downtime
Eduardo García Pérez, Head Of Central Maintenance Europe, EDP Renewables
10:00

Visual Vs. Non-Visual Inspections: What Is Really Happening Under The Blade Surface?

  • Experiences of visual and non-visual inspections from full-scale rotor blade testing
  • Benefits and limits of visual surface inspections in comparison to non-visual methods
  • What are the limitations when performing non-visual inspections?

Stepping Into The Future: Drone-Based Ultrasonic Inspection

  • Detect structural flaws, damages and failures of the blades

  • Quick access to the blades with minimal required personnel

  • No need for baskets, cranes, rope-access or similar

  • Advanced structural inspection with a selected combination of inspection tools, performed directly on the blade shell surface

Rune Yding Brogaard, System Developer, FORCE Technology

11:30

Understanding The Pros And Cons Of Performing Inspections With Drones In Comparison To More Traditional Methods

  • What kind of guarantees do you have when performing drone inspections?
  • Are photos taken from the ground a better long-term and more cost effective solution to drones?
  • Reliability issues: why is rope access and technicians still a preferred option to drones when identifying damages?

André Moura, Founder, Pro-Drone  

Boosting Blade Aerodynamic Performance By Effectively Curing Damages

12:00

Leading Edge Erosion: Advantages Of Applying Integrated Solutions For Enhanced AEP

  • How can integrated solutions avoid repairing the blade for structural damage?
  • To what extent can such solutions save power output?
  • Strategies to mitigate leading edge imperfections in order to avoid additional power loss when the erosion occurs
  • How can integrated solutions in the blade improve O&M activities?
Francesco Grasso, Aerodynamics Lead Engineer, Vestas

Reducing The Sensitivity To Leading Edge Roughness And Enhancing AEP And Long-Term Performance By Applying Aerodynamic Devices

  • Assessing the impact of leading edge roughness on the aerodynamic performance
  • Counteracting degradation of aerodynamic performance in order to enhance AEP
  • Results of wind tunnel tests of vortex generators on a thin airfoil to be mounted at the outer part of blades
  • Impact of aerodynamic devices on AEP and loads for blades with degraded aerodynamic performance
Christian Bak, Senior Scientist, DTU
14:00

Minimising OPEX By Improving Blade Maintenance Strategies

  • BLEEP (Blade Leading Edge Erosion Programme): a collaborative initiative to reduce the cost impact of leading edge erosion
  • Maximising turbine productivity by assessing the impact of leading edge erosion on AEP
  • Developing optimised maintenance strategies to minimise OPEX and maximise revenue generation
Andrew Kay, Renewable Technology Engineer, ORE Catapult
14:30

Anticipating And Avoiding Damages During The Design And Production Phase In Order To Maximise Blade Performance

  • What are blade manufacturers doing in order to anticipate and avoid defects in the blade?
  • Design solutions for each category of damage to implement in the production phase
  • Developing a pre-production method to determine when and on which part of the damaged blade to intervene
Martin Leong, Team Lead - Blade Integrity, Blade Structural Design, Siemens

Panel Discussion: Dealing With Damages In And Out Of Warranty

  • How to successfully finalise the warranty process
  • Assessing the blade conditions and determining blade repairs at the end of the warranty period
  • Risks and benefits of using third party companies when the turbines are out of warranty
  • OEM’s involvement and assistance after the end of the warranty

Participants include:

Domenico Cannatà, Director Blades Operations, Vestas
Birgit Junker, Fleet Engineer, E.ON 
Rui Meneses, Blade Specialist, Iberwind

Live Demonstration: You Do Have To Be MAD To Work Here! Making A Difference In Blade Repair And Cost Cutting

Hear about GEV Wind Power’s bespoke blade ERP package which integrates with a tablet to enable blade technicians to record inspection and repair progress as they work. This includes capturing the high resolution images of damage that are required to consider suitable repair techniques. The cloud based application gives near-realtime recording of data and integrates with a robust back-end database. In turn, the database facilitates swift and accurate invoicing alongside in-house operational metrics for performance analysis. In support of the ERP package, GEV Wind Power will provide an update on the Blade Habitat. This innovation provides a temporary shelter from which technicians can carry out repairs that would otherwise be hindered by suboptimal environmental conditions.
