Offshore Wind Project, North Sea, West of Esbjerg DK

Our client’s request

Mitsubishi Vestas Offshore Wind (MVOW) was designing a new offshore wind turbine and needed assistance in the development of a ‘Smart Aviation Obstruction lighting system’ on their new turbines. These new turbines will be used for the Horns Rev3 wind farm and for future MVOW offshore wind farms.

The challenge

In 2010, Vestas started designing a new offshore wind turbine. Throughout the design process, Orga was asked to think along with them on how to smartly integrate Aviation Obstruction Lighting (AOL) solutions into these new turbines.

We have been designing Aids to navigation lighting systems for harsh offshore locations for years and were ready to accept this challenge.

Eight years later Orga is proud to announce our collaboration with MHI Vestas Offshore Wind A/S on the Horns Rev 3 offshore wind farm which is already the 14th project we do together with MHI Vestas Offshore Wind A/S. Orga will supply 49 state-of-the art AOL systems.

Orga’s solution

Smart safety marking for Horns Rev3

Each turbine in the Horns Rev 3 wind farm will be fitted with a system. All 49 systems communicate and together they make sure the wind farm is safely marked for passing air traffic.

The turbines on the outside of the park can be seen from great distance, thanks to medium intensity lights on the nacelle and tower light systems. When you come closer, the low intensity lights show all individual turbines inside the park. The intensity of all lights is regulated to match the environmental light intensity.

The safety marking systems include our new Helihoist Winching Status light. The status light informs the helicopter pilot about the status (moving or still) of the rotor blades. With this information the pilot can safely winch an engineer on the nacelle of the Wind Turbine Generator.

One obstruction light solution, for every situation

The MHI Vestas offshore wind turbines will be fitted with the standard Central Control Unit. This means that wherever the turbine is located in the wind farm, the Central Control Unit can be programmed with a lighting scheme that matches the actual location, in any country worldwide.
