Due to capacity expansion additional tanks had to be build. The larger storage tanks: 80 meter diameter and 100.000 m3 crude oil storage capacity, proofed a challenge. These extra large storage tanks need additional automatic fire protection. To complicate things further the very low temperature during winter time of -20 degrees Celsius had to be considered to ensure operation of the system at all times.
An automatic detection and gas based extinguishing system was chosen
that is specifically designed and certified for such rim seal fires: CFI Rim Seal Fire Protection. The third party system approval: VDS approval (similar to UL or FM) on the CFI system enabled the client to obtain clearance from the authority having jurisdiction. Unlike water or foam, CF3I gas is not effected by the very cold temperatures, making this a very suitable extinguishing medium. The system is connected via the Saval SK3000 fire alarm panel to clients site control and alarm (SCADA) system.
