Come meet the poster presenters to ask them questions and discuss their work

We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!

PO100: A novel solution for Power Curve Verification of floating Wind Turbines

Dimitri Foussekis, Research Engineer, C.R.E.S.


Floating TLP-based met masts is a relatively new concept for offshore wind resource assessment. Short, non-hub-height met masts together with a lidar is already an established measurement setup for onshore resource assessment and power performance verification. Recently, FloatMast® deployed such a setup in the Aegean Sea (65m depth) and completed a 1-year measurement campaign. The on-board 40m ASL met mast was equipped with typical wind sensors (cups, vanes, ultrasonic) and lidar. Measurements from motion sensors at met mast top level and at platform level revealed the TLPs motion patterns. In brief, during this 12-month campaign (7.9m/s average wind speed at 44m ASL, 4.7m max wave height, 97% data availability), met mast's tilt angle remained below 1deg and the platform's motion period was within 6 to 8 secs (during the higher wave heights, occurred in the presence of high wind speeds). The onboard lidar was successfully verified in situ according to Annex-L of IEC 61400-12-1 at three heights (30m, 40m, 44m) against FloatMast's cup anemometers, confirming that platform's motion has negligible impact on lidar measurements. Three independent MEASNET members institutions approved FloatMast compliance to IEC 61400-12-1 standard, making it an ideal candidate for power performance verification campaigns in deep waters, where a fixed met mast is not an option.
