Naval Facilities Engineering and Expeditionary Warfare Center (NEXWC) has awarded a Task Order to SST for $2,519,435 to plan, prepare, coordinate and conduct at-sea testing to validate a floating LIDAR wind measurement system by direct comparison between a fixed platform and a Light Detection and Ranging (LIDAR) buoy. While the development and maturity of offshore wind devices progress, the collection of in-situ wind data remains a critical requirement for proper siting regardless of the type of offshore wind device implemented. General offshore wind maps have been generated based on satellite-derived data or model estimates, but such maps have a low resolution and can only be used for preliminary investigations.

The recent development of wind resource assessment buoys offer a reusable and benign device to reduce wind field uncertainties by collecting in-situ data at hub heights (~130m). Wind speed is a critical factor for any potential wind turbine site, and as such, this effort to validate is a risk reduction measure to ensure accurate site characterization.

Under this order SST will procure a LIDAR buoy unit, deploy it, conduct data acquisition, recovery, and data post-processing and analysis. SST will team with NAVFAC EXWC and execute this task order collaboratively with NAVFAC EXWC engineers, scientists and technicians.
