Document code

DNV developed a position statement regarding remote sensors devices indicating the amount of validation required in order to rely on data for energy assessment projects.

According to DNV, the WindCube is Stage 3 (the highest level) for simple terrain measurements onshore: “a device (here the WindCube) is considered proven for use in the assessment of wind farms sites. The data may be used quantitatively within formal wind speed and energy assessments with only limited or no site-specific validation against conventional anemometry”.

For complex flow and FLS (buoy/vessel) installation, the WindCube is deemed to be stage 2: “Confidence is gained that the device provides robust, continuous and accurate data over the full spectrum of operational conditions. Alternatively, specific conditions where the device does not provide robust data become well understood and can be excluded from analyses”.
