JMD DTA Contd.
Having generally addressed the involved principles for arriving the overall DTA complex layout, let us look into how the engineering and detailing proceeded at Jamnagar.
Typical of Reliance that too with Bechtel back-up, the underground piping activity started even before the basic engineering was in place. The Cooling water mains and fire water are the two which took top most priority. As these two fall under OSBL scope, the team at Bechtel London and at Jamnagar worked round the clock for accumulating the available indicated numbers by the licensors and prepared an estimated requirement. The Project,Process team , utility experts had two day mind boggling deliberations and arrived at the qty. requirements for cooling water and strategic placement for cooling tower locations and number of cells and spare/future estimates. There used to be battle royal discussing which CT should cater to which ISBL and group of plants. As AR had executed similar multi plant requirements at Hazira, calling the shots with conviction became easier and every one got convinced to endorse. AR &Dr JVK having worked jointly at Hazira , took the practical gamble of having 30% margin and contingency and prepared the spread sheet. That became blessing in disguise later including to cater to capacity enhancement as well as new plant additions in that geographical contour. Even some of Bechtel engineers got excited to be in the team and gave the momentum for progress. When it came for fire water, since we developed the overall plot plan displaying the units locations identified, the joint team- Bechtel LP, Technofire and ex-TAC officers, Reliance OSBL Projects(AR team) took the gamble of going for 10 X 1000 M3/Hr at each location- main plant area, Refinery tank farm and marine tank farm. That was because, in those days there was no specific rules for FW qty.from CCE or IS but only TAC Rules were the statutory guidelines. The odd thing in those days was- TAC rules arrived at pumping capacity based on summation of equivalent hydrant demand and 50% spare pumping capacity. The problem was that no one in the country imagined that there could be this vast requirement that may arise!; but rule was the rule and we were forced to adopt. Though Bechtel LP specialists felt odd, to follow the national statutes they could not help to reduce the number of pumps as well as pond capacity. In those days since Jamnagar was practically desert area, we decided to opt for sea water as fire water media as much as possible; but at the same time , made sure that only fresh water shall be the media for fire fighting in all ISBL plant areas. These considerations forced us to develop so many ponds and their corresponding fire water pumping system. While conceiving the cooling water and fire water network all across, every member felt the experience of life term opportunity and relished.
Here I have to include two specific points that we came across in Cooling water network routing and Fire water pumping capacity in main refinery area.
Cooling water header routing: Without realizing or having an idea of the main header diameter involved, that time Engineering President ( himself managed field execution in his period) gave instructions to Bechtel Principal Piping Engineer to route the headers on pipe rack, since Jamnagar plant area soil is of rocky nature! Jim Skipper and PB Patel came running to me saying' Ram, what can we do? The President has given us this directive and how do we abide? Should we tell Civil team to enhance and engineer the rack elements to bear 2 X 90" dia. fully loaded water pipe load that too not one but in pairs?' Having heard that I laughed and told the team to go ahead buried design only and I will manage and convince the President. Every one of them were afraid how AR is going to face this challenging task. But my job became easy. When they went and told him that AR has taken this call, immediately he changed and asked them to proceed with under ground only. I never touched this subject with him at any time. Contd....
