SIRON Engineers can carry out a site survey on or offshore where current drawings are correlated against the actual pipework, or if no drawings are available then we can as build a set of drawings from the fire pumps to the most remote nozzle. With having any up to date data with which to measure against then there is no guarantee the systems are operating as designed. When wet deluge testing SIRON record volumetric flows, nozzle pressures, deluge valve pressure and density application rates. Without up to date isometric drawings and hydraulic calculations then there is no method of proving to the AHJ or regulatory body that each system is operating as designed when released, either when routinely wet testing or a change of status calling for a deluge release.Įach deluge system is different and as such they vary in size, number of nozzles and fire water demand. For any fire protection system, it is vitally important that these isometric drawings are kept up to date and also that if any additional modifications are made to a system, that this is recorded and updated for each system.
