Samenvatting:
At present monitoring of bird collisions with wind turbines is only possible for land-based turbines. Current methods are labour intensive and therefore monitoring can only take place at a small scale. A prototype of a monitoring system that counts actual collisions and stores video registrations for species recognition has been developed by ECN and tested successfully at a 2.5 MW land-based turbine.
For application offshore a series of tests was planned in a coastal wind farm located on the Oosterschelde Storm Flood Barrier in order to test and calibrate the monitoring system in offshore-like conditions. However these tests could not start, because of warranty discussions with the wind turbine manufacturer. So far no suitable alternative locations have been found, so it is not foreseen that other installations will take place within the term of We@Sea.
In this project ECN has continued the monitoring with the current prototype. In general the system has shown to be reliable. In the monitoring period one bird collision has been recorded and also a number of other events. Tests with several novel camera types showed that the image quality at night can be improved considerably, but still not sufficiently to recognize birds in full darkness.
This report contains the status of the WT-Bird development and the progress and results of the project with the original and more ambitious planning.
