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 industry and the academic community.
PO129: Results from a Joint Industry Project on Quantifying Measurement Uncertainty of Floating LiDAR without Reference Met Masts
Mauricio Pereira, Consulting Partner, ERM
Abstract
Floating LiDA R Systems (FLS) have become the industry standard for collecting metocean wind measurements. Their application is, however, still limited by high measurement uncertainties applied to the wind speed data used for wind resource and energy yield assessments when compared to fixed meteorological masts. This is largely driven by the practice of comparing FLS to cup anemometers during the performance verification process and the potentially conservative application of specific sub-component uncertainty values. Although uncertainty values have reduced as the technology has matured, uncertainty levels exceeding 3% continue to be applied to multi-year wind resource campaigns measured from best-in-class Stage 3 FLS. This has trickle down effects as it impacts a project’s uncertainty budget and ability to secure preferred project financing. Following presentation of a reconciliation method, first presented by Copenhagen Offshore Partners during the WindEurope Tech Conference in 2023, ERM commenced a Joint Industry Project (JIP) to examine FLS uncertainty using actual offshore wind measurement data provided by offshore wind developers. An assessment in the Dutch North Sea region was previously shown by ERM at the WindEurope Technology Conference in 2024, and now ERM is ready to share results based on multiple concurrent wind measurements in the Republic of Korea. In the Dutch North Sea study, ERM demonstrated the reliability of FLS measurements compared with mast measurements by analysing relative deviations from mesoscale maps. ERM considered 12 FLS based datasets, 2 fixed LiDAR datasets and 11 met mast-based datasets from the region. ERM has now developed an analysis of variance methodology to produce another evidence-based assessment of measurement uncertainty using data from nine measurement devices in the Republic of Korea. ERM discusses the importance of an evidence-based approach in considering two significantly different geographies and what that could mean for project development and ultimately the cost of finance .
