Measurement campaigns for an offshore wind resource assessment with the in-house developed Fraunhofer IWES Wind Lidar buoy include the complete yield assessment for the development of an offshore wind project. The floating system integrates a Wind-cube® v2 Lidar device in an adapted marine buoy. Its compact design, an autonomous power system and an efficient data processing and communication system ensure reliable and flexible offshore wind measurement campaigns at minimal costs. The motion correction algorithm guarantees high data accuracy and measurement uncertainties similar to those for offshore mast measurements. in all project phases including planning, installation and operation of offshore wind power plants.

Fraunhofer developed a correction algorithm that allows LiDAR systems to carry out measurements even on moving structures. The algorithm subtracts the buoy’s own movement from the measurement values.
