We are looking forward to meeting you in Madrid next th March To get more information about event: To get more information about NRG System activity: Paris, France, 28 November This new Lidar sensor, providing real-time characterization of wind up to metres in front of the rotor plane enables turbine manufacturers to make major strides in improving the efficiency of wind energy production both on and offshore.
The Wind Iris TC Lidar measures all essential incoming wind conditions, including rotor averaged wind speed, wind direction, shear and turbulence, at multiple distances before it reaches the turbine rotor. This provides the turbine control system with the essential rotor coverage and preview time required to establish and implement appropriate control actions before the wind reaches the rotor with the critical measurement accuracy and precision required to extract maximum benefit from conditions as the wind reaches the rotor plane.
The Wind Iris TC gives the turbine a short look into the future, providing it with all the time it needs to prepare for the wind before it arrives at the rotor plane. In addition, integrating the Lidar into the turbine platform also enables optimized operation of the wind turbine over the entire lifetime of the investment by improving the alignment, gaining additional turbine availability, extending turbine life and reducing maintenance costs.
Thus manufacturers can reduce LCOE significantly and improve profitability of both existing and new schemes. Whether installed as part of turbine construction or as a retrofit as an element in a turbine life-extension project, Lidar assisted turbine control technology has the potential to redefine wind turbine design limits by reducing loads, mitigating extreme events and increasing energy capture.
The system uses four beams and ten simultaneous measurements at a frequency of 4Hz across the m range to capture events several seconds before they reach the rotor plane and track them as they evolve. Thus it provides a robust representation of the wind field in front of the rotor that is vital to ensure reliable control actions under all possible circumstances. The companies design, develop, manufacture, sell and service new turnkey remote-sensing instruments allowing wind measurement and aerosol characterization.
More information about the event here: Leosphere is speaking at MTWE conferences: Dr Ludovic Thobois will present current projects implementing Doppler Lidars network for weather observation. Day 2 — Measurement and Technology Wednesday, 11th October, from Inserting multi-function lidars into operational weather observation networks.
Existing weather observation networks have been continuously evolving from synoptic network with synoptic stations, satellites and now remote sensing. The emergence of new sensors like the coherent Doppler lidars based on optical fibre technology implies a rethink of the architecture of existing networks.
In this paper, a study will be presented to list the opportunities offered by such sensors and the challenges to overcome in order to insert them into existing networks.
A series of trials and pioneer projects will be presented, showing recent advancements in terms of validated products and how to combine them with other sensors.

More information about event here: London, 18 July Leading wind measurement experts gathered in London claimed that LiDARs have been replacing met masts to become the sole wind measurement tool used for offshore resource assessment and power curve verification purposes.
These experts stated that LiDAR technology had over the years fully proven its ability to provide wind measurements as reliably as met masts. They also claimed that LiDARs are faster, easier and much cheaper to deploy, enabling significant development and operational cost reductions. At a seminar hosted by Leosphere at the Offshore Wind Conference , top wind measurement experts explained that years of successful LiDAR validation campaigns and strong competitiveness have led industry leaders to choose this technology over met masts for offshore wind feasibility studies as well as power curve verification tests.
In practice, the use of nacelle mounted LiDARs is already frequently required in the turbine supply agreement for power curve verification testing, even if LiDAR measurements are not yet covered by IEC standards. Met masts cannot compete with LiDARs on cost in the offshore market. BOWL chose instead to install two vertical profiler LiDARs which enabled them to start the measurement campaign much earlier and without the significant costs associated with installing an offshore met mast.
The fixed LiDAR, installed on a nearby lighthouse, and the floating LiDARs located at points across the wind farm zone, enabled the company to secure reliable, bankable data adding millions of euros to the project value in addition to the millions in cost savings and the elimination of the health and safety risks associated with large met mast installation.
The prevailing view among experts is that the future of resource assessment is short masts coupled with LiDAR for onshore, and for offshore probably just the LiDAR.
Today, LiDARs are commercially ready and already used in major projects around the world. At the Offshore Wind conference in London, Leosphere brought its community together, offering a unique opportunity for users to challenge their views and learn about the potential offered by LiDAR technology, quickly becoming a standard in offshore.
Major offshore wind energy players have shared their experience on a wide range of applications, from energy yield assessment to contractual power performance testing. Best practices in offshore Lidar applications from different perspectives were presented, with case studies from developers, OEMs and consultants. All presentations are available on request.

In this project, the Windcube S is collecting wind data on a continuous basis to understand 3D characteristics of the ABL of the Arctic. The second objective is to study the interaction of the ABL and Arctic clouds to understand their life cycle.
The Leosphere Windcube was chosen for the KPOPS project because of its demonstrated ability to profile the ABL with a good data availability and quality, and for the limited required maintenance, even when deployed outside in very harsh environmental conditions like those observed in Ny-Alesund.
The first measurements gathered during the winter will be compared with the AWI Windcube data. Press Release available in PDF format: More information about the fair: A cette occasion, nous avons été invité à présenter notre Windcube.

On Monday, the 4th of April , Ségolène Royal, Minister of the Environment, Energy and Marine Affairs, announced the third offshore wind farm tender for a site off the coast of Dunkirk. The call for tender procedure should be launched during this summer. They are able to perform a full 3D mapping of the atmosphere to provide remote measurements of wind speed, direction, turbulence, and boundary layer height.
London, UK, June http: To see the document: Two types of experimentation are planned: To know more about this projet, you are invited to consult the PDF document. In the same timeframe, we will proceed with the second installation phase at FINO1 for the DCF sonic turbulence meters and breaking wave camera system. The meteorological and oceanographic measurements will run in parallel until the fall, when the oceanographic measurement buoys will be recovered.
Benny Svardal at Christian Michelsen Research is responsible for the project management. The key purpose of the campaign is to improve our knowledge of the marine boundary layer stability, air-sea interaction and offshore wake propagation effects. The collected observational data will be used to validate and improve numerical models and tools for i. Additionally the campaign scope will cover research on motion correction techniques for floating sensor platforms.
In order to provide unique datasets for the study of boundary layer stability in undisturbed offshore conditions, we will perform simultaneous measurements of wind, temperature and humidity profiles in the MABL. By employing microwave radiometer and lidar remote sensing technology, we are able to map the boundary layer conditions continuously up to an altitude of m.
To investigate the atmospheric stability around the wind farm, as well as the interaction of the Alpha Ventus wind turbines with the atmosphere and each other, NORCOWE plan to install two scanning lidar systems and a microwave-radiometer on the research platform. This is the first time that such an instrument is installed at on offshore location. Both the Lidar systems and the radiometer are able to perform continuous measurements up to an altitude of m. This instrumentation, mounted on bottom frames, submerged buoys, and the autonomous SailBuoy, will monitor wave statistics, surface currents and turbulence in the upper oceanic mixed layer.
The collection of these data is crucial for studying air-sea exchange processes, which are known to influence the structure of the vertical wind profile and the atmospheric stability. The deployed instrumentation will provide a highly versatile data set for investigation of the offshore wind profiles, wind shear and turbulence intensity as a function of atmospheric stability in and around the wind farm.
The gathered data opens for the investigation of the structure, extension, dynamics and persistence of single turbine wakes and the near farm wake of Alpha Ventus. To know more about: The Experiment is a field campaign that aims to quantify uncertainties in Doppler lidar measurements of wind conditions. The units have been through acceptance testing and calibration, and NORCOWE personnel have completed thorough training programs arranged by the suppliers.
For the next weeks we will map the wind and temperature conditions in the complex terrain surrounding Bergen and perform comparative measurements with the weather radar already installed at StormGeo. In addition, this deployment will provide valuable experience with equipment and measurement strategies as preparation for the upcoming FINO1 campaign.
