MALIBU

Model-based approach for floating lidar based offshore wind potential measurements

Content

Floating lidar buoys provide a flexible and, particularly, cost-effective approach for assessing the wind resources at offshore sites. However, since the buoy motions have an impact on the lidar measurements, it is supposed that a detailed recording and understanding of this impact is an essential pre-requisite for applying the technology at a fully commercial level, in order to utilize the full potential of lidar buoys. It is already recommended practice to monitor external influences – as e.g. relevant sea conditions or atmospheric measurement parameters – in parallel to a lidar-buoy measurement and relate these values to the measurement performance of the system.
The MALIBU project shall go a step further: it is planned to develop a simulation environment for floating lidar buoys and, in a second step, link this simulation model to an uncertainty assessment for floating lidar measurements.
