Abstract

With the Greek government announcing a large expansion in the offshore wind power capacity in the Aegean Sea, industrial players in the region are starting to consider how to conduct the wind resource assessments that they will need to respond to tenders. Offshore, several different lidar technologies have largely replaced the use of met masts due to their lower cost, ease of installation and reduced ecological impact. The most common solutions are floating lidar systems (FLS) but long-range dual scanning lidars (DSL) have also attracted attention due to their ability to measure the offshore resource whilst being installed onshore. DSL measurements generally have lower uncertainties than their floating counterparts but direct measurements from them are constrained by a maximum range of roughly 10km. The Aegean Sea however is home to over 150 islands and this presents an opportunity to extend the range of DSL to many areas beyond range of the mainland. This work uses a previously validated dual scanning lidar error model, a public database of Aegean island coastlines and an algorithm to optimise the siting of the two lidars to produce a map of dual scanning lidar measurement uncertainty over the entirety of the Greek offshore surroundings. These uncertainties can then be compared to that of a FLS to produce a recommendation on where to use DSL, and where to use FLS for the offshore wind resource assessment in the Greek offshore market. This comparison is provided in cartographic format for easy reference.
