Deutsche Windtechnik is granted the world's first approval for the use of ADLS at an offshore wind farm

The Nordergründe offshore wind farm is the first offshore wind farm in the world to be equipped with a fully functional, officially approved Aircraft Detection Light System (ADLS). Deutsche Windtechnik had already upgraded all turbines at the offshore wind farm with its proprietary transponder-based ADLS in May 2022, and the operating permit has now been issued by the corresponding authorities.


Deutsche Windtechnik's offshore service teams have equipped the Nordergründe wind farm with ADLS, making it the first German offshore wind farm to receive this type of system.

This makes Nordergründe the first near-coastal offshore wind farm in the world to have its light emissions reduced to a minimum. Deutsche Windtechnik's comprehensive experience makes it a reliable partner for other operators, who are required by law to retrofit their offshore wind farms with ADLS by the end of 2023.

"The installation of our ADLS at the offshore wind farm Nordergründe went smoothly," said Jens Landwehr, Managing Director of Deutsche Windtechnik's offshore unit. "We equipped two turbines with our ADLS and put them into test operation during the previous months, so we were very well prepared and could equip the remaining sixteen turbines within a short period of time. We completed up to two turbines on each day of work."

All services related to the projects were carried out and supervised by offshore service teams and staff of Deutsche Windtechnik's Technical Controlling, Technical Support and Control Systems departments, including supplying the ADLS, installing it, upgrading the warning lights, the entire range of offshore logistics, and support with the approval procedures. Jens Landwehr said: "Our internal processes for installing our ADLS at offshore wind farms have now proven themselves in a real-world scenario. This makes us a pioneer in the global offshore market, and we are ideally positioned to retrofit ADLS at other offshore wind farms."
