The new material and storage handling facility at Gladstone Quay in the Port of Liverpool, is designed and constructed to handle three million tonnes of hazardous classed wood pellets per year.
Hall & Kay delivered automatic deluge water spray protection to the biomass unloading conveyors, with Sprinkler protection to the four highest transfer towers, all to NFPA/FM Global standards, in addition to water supplies for specialist detection / suppression and wash down systems.
The water supplies consist of two full duty diesel driven Fire pumps, either pump capable of 150% of the required flow, as per NFPA requirements. They have been sized to allow for three Deluge valves operating simultaneously and still provide 10.2mm/min. They are supplied by twin FM approved inter-linked water storage tanks, each holding 300 m³ of water, which will allow the system to operate on full demand for two hours.
Water supplied by these pumps and tanks is then distributed through an underground water main that runs the length of the site and branches off at strategic points throughout, to provide water supply to the 18-off fire and wash down system GRP Valve Stations.
