Abstract

EOLOS Floating Lidar Solutions is a Floating Lidar Service provider based in Barcelona, Spain. In 2015 it became an industry accepted technology by meeting the Carbon Trust Stage-2 requirements. In April 2022 the FLS200 achieved the highest commercial maturity, Stage-3, in accordance with the Carbon Trust requirements. These included three validation campaigns of at least 3 months in which a complete characterization of the buoy's type was performed. In all of them, data availability and accuracy met best-practice acceptance criteria and classification studies showed no additional sensitivities to the Lidar measurements. The EOLOS FLS200 is a fully-equipped and energy-autonomous wind measuring system based on LIDAR technology fitted with oceanographic instrumentation. It mounts a ZX300M, which is an offshore environment adapted Lidar able to measure wind speeds and directions up to 200m above the sea level. The device's provider is ZX Lidars. Several other sensors are mounted on the buoy allowing the gathering of met-ocean data such as; sea states, current profiles, atmospheric temperatures and pressures, solar radiation, sea water temperature and precipitation. This work intends to perform a comprehensive sensitivity study of the buoy using a unified and extended dataset comprising the data collected from 4 validation campaigns (1 from stage-2 and 3 from stage-3). The sensitivities of the Floating Lidar System (FLS) wind-speed measurements to environmental variables measured either by the buoy or the reference system are computed. The results of this joint study give a more thorough overview of the FLS200 sensitivities. This study explores some alternative uncertainty evaluation methods which prove to give reasonable results, and it suggests that traditional methods might be too conservative in some cases.
