The start-up

EOLOS LiDAR buoy can take wind measurements from sea surface up to 200 meters with a precision similar to a met mast, but only for the 10% of its cost. Additionally, the buoy measures wave and current data, which up to now had been done by a smaller buoy.

The need

Offshore wind farm investments need reliable wind assessments in order to estimate the wind energy potential of the site where the wind turbines are to be installed. Performing wind assessments with no high quality on-site data increases uncertainty, hindering the project’s bankability and increasing its financial risks.

The current costs for performing offshore on-site wind measurements are very high, as those include the installation of costly bottom fixed met masts. Additionally, these systems are stationary, only allowing them to take measurements at a single coordinate point.

The solution

EOLOS LiDAR buoy offers a low cost, accurate and reliable offshore wind data source, allowing the performance of measurements at heights over 200m above sea level, and at much lower costs (up to 10 times less) than conventional bottom-fixed offshore met masts. Moreover, it offers positional flexibility and can be reused in other areas within a wind farm site (or on other sites), potentially reducing the uncertainties of wind speed measurement.

Value proposition

EOLOS’s competitive advantage relies on the precision, availability and completeness of data acquisition as well as its sturdy and optimised structure designed to withstand offshore operations, and at the same time easing its transportation. It also offers an advanced data processing tool based on a purposely-developed wind, wave and current combined numerical model, providing an integral solution for the current challenges of offshore wind assessment.
