Roland Hagendorff of Projekt GmbH has once again been elected as a speaker for the working group "Marking wind energy turbines" of the German Wind Energy Association (BWE). He brings to the office his expertise in the area of offshore wind energy turbines.
The goal of the working group is to cooperate with the responsible government departments, flight security organisations and experts to find solutions for new, more efficient marking systems. These are necessary because of ever-taller towers, but must also respond to environmental concerns. Right now, discussions focus on ways of activating lighting on demand, using either radar or transponders in aircraft.
The speakers" group of the Marking WG regrets that the systems envisioned with the aim of increasing acceptance will first be tried out abroad. The first primary radar system developed, "OCAS", was shut down by the German Network Agency due to frequency overlaps with military radars, so now an initial wind farm is due to be equipped with "Cassidian" modules at the end of 2012. In order to promote the transponder solution, the WG also demands a general "night-time transponder obligation".
Roland Hagendorff has in the past cooperated on various BWE projects, including the HIWUS study "Development of an Obstacle Lighting Concept to Minimise Light Emissions from Onshore and Offshore Wind Energy Farms and Turbines, with Special Reference to the Compatibility of Environmental Requirements and Air and Marine Traffic Safety". He also sits on the BSH"s "Protection and Safety Strategy" working group.
