BA Stn. Implementation
Having conceived the breathing air requirement and number required & location identified in gazification complex/s, a fresh point arose! Somebody in the group questioned, what will you do
if the utility air compressor supply air quality deteriorate and toxic rich supply air is present in the distribution header? That too somebody is utilizing the BA take off provision in field at that time for his operation/maintenance task in the field. That was a valid question and a practical one. So the team carried out a logistic movement study calculation. As it is we have planned to make provisions of emergency situation air bottles with harness assembly placed at strategic points at ground elevation. When we did a calculation on the basis of normal human being air consumption, a 2 kgs filled air bottle can help a person for 14.5 minutes time breathing to escape from that unsafe area.
Taking that as back up, we decided to put 2 kgs air bottle as emergency back up in all BA take-off points which are at elevation more than 15 M from ground level.
Having decided that way, we went in to analyse the changeover switch provision in the harness assembly.The two vendors who competed technically had that issue addressed already and they were the people who insisted that the supply air pressure should be at least 6 kg/cm2 g pressure. So that solved our worry.
With all these home work , my team could arrive at the total MTO for the components that form the BA station assembly. Through system they could raise the MR, to enable the procurement to commit the supply order on the recommended bidder. The recommendation was on M/S MSA and the party wanted to take the order to be executed from their Germany office, who source the air filter assembly ®ulator package from M/S Parkar, world famous reputed source. But in the process there was a catch! Until that moment, all concerned were focused on component selection only but not as Breathing Air Assembly!
For procurement sake, the engineering team was forced to look into component wise and generate their SAP code but nobody have looked the requirement of finished/tested assembly package ! Unfortunately even the two bidders who were technically acceptable, did not think of the task of design/fabrication of container indigenously and assembling the sourced components and test. In Reliance, people concerned could not distinguish the scope and responsibility difference between component supply and field assembly / testing!
Added to misery, MSA was banking upon their local distributor only to undertake that task as they do not have their own resources to undertake that assignment in India. But RPMG management was hell bent to give the order only direct to MSA. Here I was forced to play the balancing game in handling the situation and made sure that the MSA Indian distributor carry out the design from fundamentals
and I personally reviewed the assembly drawing features , especially with respect to interface issue with the main header piping , relative location of hose drum assembly with filter/regulator etc. That party got the containers fabricated at a shop in Ankleshwar , got them inspected by TPI and carried out the field assembly and testing at JMD. In the bargain I became a bad boy in the eyes of RPMG management! Moreover, when it came to ordering, procurement made the blunder of including field erection of assembled containers in various positions even at high elevations under the scope of MSA. Strictly speaking, it should have gone under the scope of pipe erection contractor in respective area. So I have to interfere on that account; but the construction management group have understood rightly and included that in piping contractor scope and got executed.
