A buoy and a laser
Precise knowledge of wind patterns is a prerequisite for deciding on the location of an offshore wind farm and then for positioning the individual turbines. Wind speed, in particular, must be known. Measurement masts are used that are costly to build and complicated to manoeuvre and position, especially when remote from the coast and in deep water. EDF Group teams(1) have found a way around these complications by identifying an existing innovative technology that they approved technically and adapted to the Group’s needs.
Known as floating LiDAR (Light Detection And Ranging), it takes the form of a large mobile buoy equipped with a laser beam.
