Resource monitoring

Two LIDAR (Light Detection And Ranging) based measurement systems have been developed, installed and tested in the North Sea, to gather more accurate wind data and enrich the offshore wind resource models in development.

First a fixed LIDAR has been installed on an offshore platform to collect data at hub height and enrich the datasets available through standard measurements. The data from this LIDAR will help increase knowledge of the wind climate in the North Sea and will be made available to the NORSEWinD wind atlas.

Secondly, a floating LIDAR device has been developed as a tool for more flexible, accurate and cost-effective measurements, within and outside wind farms. Developed jointly by 3E and OWA (Offshore Wind Assistance, a subsidiary of Geosea), this highly innovative floating LIDAR, known as FLIDAR, is the first floating LIDAR resource assessment device validated in North Sea conditions. The high-tech infrastructure and rescoure monitoring services has been implemented in a new company Flidar NV.

The system is made up of an industry standard buoy adapted to marine regulations for faster permitting. A best in class, offshore ready, Leosphere LIDAR device is secured on top of a mechanical stabilisation system on the buoy whilst a set of PV panels, small wind turbines and battery pack provides independent power supply. A software algorithm is used to correct the data which is then retrieved and communicated via satellite or GPRS to a web based monitoring and reporting tool (SynaptiQ).

Using the FLIDAR, floating LIDAR will make it possible to:

  1. Reduce CAPEX and OPEX of offshore wind resource assessments
  2. Reduce and shorten permitting requirements
  3. Perform fast, efficient and flexible resource measurement campaigns, within and outside of wind farms, at all project phases.

Being highly mobile and easy to transport, the FLIDAR is particularly suited for resource assessments during wind farm operation and detailed wind turbulence and wake analyses.
