Access And Inspection Methods To Reduce Blade Downtime And Enhance AEP


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

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?

Eric Putnam, Project Engineer, Fraunhofer IWES


Shearography – A Fast And Flexible NDI Technique For Composite Materials

Offshore Access For Rotor Blade Inspections: How To Avoid Delays And Energy Loss

  • Speeding up the repair process and make the most out of accessible offshore weather conditions
  • Rope inspections: what are the lessons learnt from onshore that can be applied to offshore health and safety procedures?
  • Are technicians fully trained for offshore maintenance, to identify the damage and quickly recognise the best repair solution on the spot?
  • To what extent is onshore technology suitable for offshore inspections and repairs?

Steven Lindsay, Business Development Director,  Renewable Advice


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

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

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

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.

Alastair Gadney, Projects Director,  GEV Wind Power
