![]() ![]() Increase in pipe sizes is required to arrest velocity within recommended limit in these areas. Simulation indicated that fluid velocity was above 3.5 m/s at specific sections on the ring main. Hydraulic analysis found that pressure was above minimum requirement of 7bar (g) at the most remote point in network. Additional flow may create pressure spikes and surges in FWN. ![]() The study identified that each existing fire water pump is suitable to deliver 1400 m 3/hr against required flow of 1000 m 3/hr. Study also engaged pump vendors to establish feasibility of modifying the existing pumps. Study revealed reduction in flow, head and pressure to mitigate fire water piping surge problems. Study explored various operating configurations of existing 4-working+ 4-standby pumps with active involvement of operation personnel followed by hydraulic and surge analysis with different operating scenarios. Initiative was to identify problems, evaluate root cause and think of optimization including some cost saving solutions. This paper presents measures that ADNOC Gas Processing have adopted to achieve improved system efficiency and lower operating cost.Ī study was undertaken by GASCO to review issues with existing Fire Water network (FWN) at Ruwais to enhance overall performance of system in terms of design, operation and control. A comprehensive study of complete firewater network and review of operating and control philosophy performed in order to optimize the system performance and mitigate pressure surge problems. With focus on enhancing Integrity and efficiency, ADNOC Gas Processing identified an opportunity for optimization of existing FRP firewater system in Ruwais.
