Complete solution for the once in a century project impresses.
The Fehmarnbelt Tunnel, upon completion, will be the longest immersed tunnel in the world. For illumination during the construction and equipment phase, RSRG, through RS Safetec, was contracted by FLC (Femern Link Contractors).
Construction on the Fehmarnbelt Tunnel began in the summer of 2020. Once completed, the road and rail tunnel will connect Germany (Puttgarden) and Denmark (Rødbyhavn) under the Baltic Sea, creating a direct rail and road link between the metropolitan areas of Hamburg and Copenhagen.
Rhomberg Sersa Rail Group, through RS safetec, will bring light to the tunnel. Following a demanding proposal and concept phase, they convinced the client with a complete solution. RSRG's lighting specialists will provide all power cables (halogen-free flexible construction cables with pre-assembled plugs), distribution cabinets, emergency lighting units, and light sources, consisting of flexible LED strips with a section length of 28 metres from a supply point of a tunnel element.
The project includes a total of 79 tunnel elements of 217 metres each and ten special elements of 38 metres each, as well as elements in the access ramp areas. The entire energy and lighting system is designed on a plug-andplay basis, allowing for easy installation with minimal prior knowledge. The emergency lighting units ensure reduced emergency lighting in the tunnel in case of a power failure, with an autonomy time of 120 minutes.
