Deluge System Hydraulic Calculations & Isometric Drawings

SIRON have worked with clients who have assets approaching 40 years old offshore. Ageing infrastructure and the maintenance of the platforms and rigs is an important safety critical aspect for personnel onboard. Due to the age of our client assets we have found on multiple occasions that the deluge system pipework isometric drawings are either incomplete, out of date or missing completely.

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. 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. Each deluge system is different and as such they vary in size, number of nozzles and fire water demand. When wet deluge testing SIRON record volumetric flows, nozzle pressures, deluge valve pressure and density application rates. With having any up to date data with which to measure against then there is no guarantee the systems are operating as designed.

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.

This data is then sent onshore and our office Engineers can complete a fresh set of hydraulic calculations using the latest Pipenet software and also a set of drawings using the latest in AutoCAD software. SIRON has helped many clients with a turnkey solution that offers the least amount of disruption for offshore or onshore activities and thus improving the safety of everyone at the location.
