Tunnels are sensitive traffic bottlenecks and consequently extraordinary vulnerable in case of accidents or fire blasts. Danger for life and enormous economic consequences ask also for technical solutions of prevention and limitation of damage.LIOS Technology and its Croatian partner Tehnomobil have set a new standard for modern fire safety solutions for the road tunnel network in Croatia.
Croatia is located in South-Central Europe and shows diverse terrain, including: rolling hills in the continental north and northeast, densely wooded mountains and rocky coastlines on the Adriatic Sea. The highlight of Croatia's recent infrastructure developments is its rapidly growing highway network which puts focus on tunnels as well.
Tehnomobil’s excellent engineering and contracting background in traffic infrastructure and fire fighting industries perfectly match with LIOS Technology’s comprehensive experience in fire detection applications for tunnels and special hazard buildings with an impressive track record of more than 2000 installed fibre optic temperature sensing systems worldwide.
Best fire surveillance for more than 90 % of the road tunnels in Croatia
At present an impressive share of more than 90 % of the Croatian road tunnels are equipped with the fibre optic fire detection system by LIOS Technology. In 28 tunnels with in total 55 tunnel tubes the purely passive LIOS fibre optic line sensor cable has been installed by Tehnomobil for reliable and fast fire detection. Those tunnels with tube lengths ranging from 500m to almost 6000m were newly opened in recent years or re-opened after full refurbishments where the conventional line type fire detection system could be replaced by the fibre optic LIOS system. Within LIOS Technology’s long list of tunnel projects in Croatia it is worth to stress the tunnels Veliki Glozac and Brinje which received best scores at recent European tunnel safety rankings.
