EERA JP Wind & SETWind Annual Event 2019 – Parallel session 6: Structures, materials and components – SP7

Chair: Arno van Wingerde, SP7 Coordinator

This session had a slightly different focus than most other sessions, since traditionally a workshop of the subprogramme is held adjacent to the Annual Event, which is actually the main focal point for knowledge exchange between the members. Thus, the main objective of the session was exposing the state-of-the art in R&D of the Subprogramme to other EERA members and serve as a springboard for future cooperation.

The session contained three presentations:

  • Digital Excellence for the Offshore Operations and Maintenance – Urko Leturiondo, IK4
  • Structural Reliability for the Wind Energy Sector of the future – Mireia Olave, IK4
  • Wind turbine blades erosion: state of the art and future developments – Beatriz Mendez, CENER

Although the three presentations selected for presentation in this session came from the same country, Spain, the topics were very different, affording a nice overview of the challenges within the subprogramme for the future of the wind energy.

Digital Excellence for the Offshore Operations and Maintenance
The presentation identified research gaps, namely the smart wind farm operations, performance management, lifetime management and lastly remote monitoring. Structuring the presentation in terms of research gaps and key actions certainly helped to open up the topic for discussion. This first presentation sparked the most vivid discussion, on the topic of lack of data for the research communities, ranging far beyond the topic of the presentation itself.

Structural Reliability for the Wind Energy Sector of the future
This presentation, structured the same as the previous presentation, since both were from the same organisation also identified research gaps, in this case lifetime evaluation methods and tools, reduction of the need of large(r) testbenches. field reliability data for the improvement of existing and new designs and lastly repair of structures and components for lifetime extension.

Wind turbine blades erosion
This effect, which continues to harass the industry is being studied by CENER, in cooperation with other EERA partners, mentioned were projects and cooperations containing DTU, TNO, IK4, VTT to mention a few. The need for further characterization and standardization, inclusion of the roughness and erosion into the blade aerodynamic design and new sensors to detect, directly or indirectly degradation of the blade surface and less sensitive airfoils and better coatings were mentioned.

Discussion
Although the session was at the end of the day, the vivid discussion and participation of seemingly almost all people present certainly serves as a justification for the format of the annual event and although the meeting ran almost half an hour late, very few people left. The impression was that most participants got “value for money” at the session.
