M30 Tunnel<br />
The ma<strong>in</strong> objective was to provide a fire suppression<br />
system with reasonable <strong>water</strong> consumption for large,<br />
wide <strong>tunnels</strong><br />
‣ Full scale fire tests prove system efficiency and design<br />
‣ Tested, verified options: deluge, hybrid, and spr<strong>in</strong>kler<br />

HI-FOG design for M30 tunnel<br />
‣ Hybrid system design for 3 x 24 meter long zones<br />
‣ Flow rate ca. 4000 l/m<strong>in</strong><br />
‣ Two pump stations and redundant units<br />
‣ 3000 spray heads and tunnel spr<strong>in</strong>klers <strong>in</strong> 98 zones<br />
‣ Coverage is 2.4km <strong>in</strong> five different <strong>tunnels</strong><br />

Conclusions<br />
‣ Mari<strong>of</strong>f’s <strong>water</strong> <strong>mist</strong> tunnel design is based on the various<br />
full scale fire tests<br />
‣ Mari<strong>of</strong>f’s <strong>water</strong> <strong>mist</strong> <strong>systems</strong> have a good performance with<br />
low <strong>water</strong> consumption<br />
‣ Water <strong>mist</strong> <strong>systems</strong> are recognised by third parties and<br />
customers to be efficient, viable solution <strong>in</strong> <strong>tunnels</strong><br />
