Vaisala and DNV have unveiled guidelines for using scanning lidars in a dual system configuration (DSL) for offshore wind resource assessment (WRA).
The release of these guidelines aims to help improve dual scanning lidar bankability, as well as contributes to creating the International Energy Agency (IEA) Task 52, the recommended practice on using scanning lidar measurements offshore.
The guidelines outline the different phases of a typical DSL campaign for wind resource assessment, including planning, installation and operation. The Dual Scanning Lidar Principle section explains the math for reconstructing horizontal wind speed and direction from two line-of-sight wind speed measurements and discusses factors influencing uncertainty.
“The maturity of DSL systems now allows us to confidently utilize them for bankable wind resource assessments,” says Robert Menke, senior engineer at DNV. “By releasing this guideline, we aim to accelerate the adoption of DSL technology, empowering industry professionals to harness its full potential in driving sustainable energy solutions.”
