LiDAR Offshore Wind Monitoring Solutions for Australian Offshore Wind Farms

what is offshore wind liDAR?

Offshore wind lidar (Light Detection and Ranging) is a remote sensing technology used to determine wind speed, direction, and other atmospheric variables (like temperature, humitity, and pressure) crucial to offshore wind farm operation. Lidar systems can accurately profile wind conditions across various altitudes by emitting laser beams into the atmosphere and analysing the reflected light, providing valuable data for optimising wind turbine performance, improving energy efficiency, and ensuring the safety and reliability of offshore wind operations. This technology is critical in the development, operation, and maintenance of offshore wind farms, assisting in the maximisation of energy production while lowering costs.

Vertical Profiler wind LiDAR - Molas B300M

How does vertical profiler wind LiDAR work?


The operational principle of vertical profile wind lidar involves the emission of laser beams into the atmosphere, followed by the measurement of the scattered light that is then detected by the sensor. The underlying principle of this technology is rooted in the Doppler effect, which entails a shift in the frequency of the reflected light that is directly proportional to the motion of atmospheric particles, such as dust or water droplets. Through the examination of these alterations in frequency, it becomes possible to ascertain the velocity and orientation of the wind at different elevations, thereby constructing a comprehensive vertical representation of the wind.

Molas 3D Dual Scanning LiDARs solution as Virtual Met-mast for offshore wind resource assessment

Dual-scanning lidars can serve as virtual met masts, delivering full wind observations that were previously only available from physical meteorological masts. This virtual technique is especially beneficial for offshore settings where constructing real masts might be difficult and expensive.

With dual LiDAR solutions, the uncertainty of wind resource assessment has been significantly reduced. Due the its long range of Molas 3D (10km typical), the deployment is much easier and more flexible to enable us to acquire reliable data without any physical access. 

Synchronous control technology enables dual radar beams to point at the same position in three-dimensional space, enabling real-time calculation of horizontal wind speed and direction.
