ECE Offshore performed in-depth trials to investigate the feasibility of using LIDAR systems for monopile inclination monitoring from floating platforms.
Various LIDAR systems were tested and the results were verified against Total Station obtained ground truth measurements. Key figures obtained during the test:
- The relative inclination measurement error over a 1200s continuous measurement was 0.013°, which provides the possibility to have absolute inclination measurement errors below 0.25°.
- The relative xy-position had a measurement error of approximate 1mm
Depending on the used sensors, measurement times took 200ms-1s which is sufficiently fast to perform measurements from a floating platform.
