Digital transformation in transport reopens Mont Blanc tunnel
Mont Blanc is the highest mountain in the Alps, rising more than fifteen thousand feet above sea level. Its location is somewhere in the middle of the border between Italy and France. A popular tourist destination known for its hiking, skiing and snowboarding. Below Mont Blanc is the Mont Blanc tunnel, which connects France with Italy along the E25 highway. It is a strategic road as it is an important commercial route, especially for Italy, which uses it to transport 1/3 of its cargo to Northern Europe. In 2018, a total of 1,956,179 vehicles crossed the Mont Blanc Tunnel.
Fire in the Mont Blanc tunnel in 1999
In March 1999, 39 people died when a truck loaded with flour and margarine caught fire inside the tunnel. Closed for three years for renovation and improvement. It could not be reopened for business using the same technologies and forms of work. Tunnel operators had to show that they can avoid accidents, but if an accident does occur, the response will be quick and effective.
What were the problems in the Mont Blanc tunnel?
Entrance to the Mont Blanc Tunnel
There were two main problems: first, neither the French nor
the Italians could reliably determine when the real problem arose. Second, even
when they realized the problem, they were unable to respond effectively and
adequately.
Mont Blanc Tunnel EEIG (European Economic Interest Group)
has commissioned Giordano & C, an Italian system integrator, to create a
Single Operations Center in the Mont Blanc Tunnel. The solution is called
“LOGOS” (an abbreviation of “Localiser Organizer et Gérer les Opérations de
Sécurité”, which translated into English means “Find, organize and manage
security operations”).
Results: Stratus Technologies and Wonderware by AVEVA
The LOGOS solution has more than 200,000 points. Based on
the Wonderware system platform from AVEVA and Stratus Technologies everRun, it
is the first SCADA system in the world to meet the EN 61508 SIL (Safety
Integrity Level) 2. A single operations center monitors and controls the entire
7.2 km tunnel. It can automatically react when a fire breaks out in tunnels,
creating a vortex of currents strong enough to extinguish the flames. This is
an elegant solution that not only works, but also completely duplicates.
