Nordergründe gets approval for Aircraft Detection Light System

Nordergründe offshore wind farm is the first offshore wind farm has been cleared by authorities to use a fully functional Aircraft Detection Light System (ADLS).

According to Deutsche Windtechnik, a wind turbine operations and maintenance provider, the installation of ADLS makes Nordergründe the first near-coastal offshore wind farm in the world to have its light emissions reduced to a minimum. The company 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.

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.

"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."

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."

Nordergründe is located in the North Sea, off the coast of Germany, approximately 15km north-east of the island of Wangerooge. It is expected to generate enough energy to cover the needs of more than 100,000 households. It features 18 Senvion 6.2M126 turbines with a combine overall capacity of 110.7 MW.
