Joint research effort of global wind energy actors enables more accurate offshore turbulence measurements

Core Viewpoint - The collaboration among global wind energy stakeholders, including Vaisala, aims to enhance the accuracy of offshore turbulence measurements, which is crucial for the design and operation of wind farms, ultimately improving their profitability [1][9]. Group 1: Research Project Overview - The POWSEIDOM JIP, led by France Energies Marines, focuses on developing high-performance measurement and modeling tools for assessing turbulence at offshore wind energy sites [2]. - The project aims to provide better design and operational safety for offshore wind turbines and farms through improved turbulence measurements [2]. Group 2: Technology and Methodology - Lidar technology is identified as the most suitable for understanding wind conditions at sea, offering a cost-effective and reliable alternative to traditional met masts and anemometers [3]. - The research utilized a Vaisala WindCube v2.1 profiling lidar at Planier Island, located 9 km offshore, to capture undisturbed atmospheric events relevant to floating offshore wind farms in the Mediterranean [5]. Group 3: Findings and Recommendations - The research resulted in valuable data on mean winds, turbulence intensity, and low-layer jets, which are essential for calculating turbulence forces on turbines [6][5]. - A preliminary motion compensation algorithm for measuring turbulence was developed, enhancing the accuracy of lidar measurements in dynamic sea conditions [8]. Group 4: Future Directions - The POWSEIDOM JIP continues as part of the DRACCAR-NEMO JIP initiated in 2023, indicating ongoing efforts to advance offshore wind farm operations [9].
