The Bømlafjord tunnel is one of Norway’s longest and deepest subsea tunnels, at 7,820m long and reaching 260m below sea level. Due to the location of the Bømlafjord Tunnel, it is vital incidents are detected quickly and emergency assistance can respond efficiently. The Norwegian Road Authority was aware that traditional detection technologies have limited visibility in the event of a fire. They wanted a detection system they could rely on, in all situations, to enhance the safety of the tunnel.
About the project
The Norwegian Road Authority now uses ClearWay’s Situational Awareness technology to ensure emergency teams have accurate information when responding to incidents in the Bømlafjord tunnel. Able to see through smoke in a fire, it pinpoints the location of people and their vehicles whatever the conditions inside the tunnel. ClearWay also provides Automatic Incident Detection in the subsea tunnel. A legal requirement, it detects incidents within seconds and sends an alert to the central control system. This allows warning signs to be displayed to drivers to help prevent secondary incidents.
