Hydraulic Study of Fire water network
As Reliance manufacturing locations were going on expanding by addition of new plants as well as undertaking revamp of existing units, it was felt by the team that we should carry out a detailed study and analyze the veracity of the network capacity and sizing, not only meeting company's internal standards but also satisfy the country's statutory norms.
Especially in the case of JMD, since we used the original refinery network itself for catering to the new gasification complex both in DTA and SEZ, Mr Umesh Khandalkar, Chief Fire Officer of JMD had certain apprehensions about the remote point remnant pressure criteria. So we formed a core team of members drawn from RPMG Projects, TechnoFire, MEC ,JEC and the end user fire team of the respective manufacturing complex for undertaking these studies and check.
As common members self,Dilip Koimattur and Anthony of MEC took the lead role for all the sites.
In case of JMD, M/S Arvind Induchoodan and Mukesh Kumar of JMD fire team and Maulik Kothari of JEC participated and contributed effectively. While literally carrying out the analysis only, we realized the facts about the real challenge to arrive at the various probable scenario combinations!
In the case of DTA network, since we had 16X1000M3/Hr fire water pumping capacity installed originally meeting erstwhile TAC norms(pumping capacity of 150% of sum of the equivalent hydrants in that network).there was never an issue with respect to capacity but we were worried about the remotest point remnant pressure.When we initiated the exercise, we were not aware that the total linear length of the network go as high as 120Kms.! Added to the misery, lack of coordination between Bechtel/MEC with M/S Fluor(the party who carried out the detailed engineering for DTA gasification complex) caused more misunderstanding and interpretation issues. The team deliberated deeply and arrived at various probable combination of worst case scenario of fire incidence. They are:
In DTA Refinery -2 simultaneous max. case- FCCU plant and Aromatics tank farm
In Gasification complex-2 simultaneous max. case- One Gasifier module and AGR plant
In DTA Refinery and DTA Gasification Complex- One max.case in each- FCCU or Aromatics tank farm and AGR in DTA Gasification complex.
Beauty was that the original network configuration as well as new extension to DTA gasification had redundant arrangement, we could get the remote point remnant pressure as high as >8.5 Kg/cm2g against the mandatory requirement of 7 kg/cm2 g only. So in this case, the check requirement to meet OISD Standard guidelines became a formality only.
But when it came to SEZ,there were many issues right from spare pumping capacity .We shall see in next....
