JERP Execution- Experience and Challenges
Let me start from source point itself!
As already mentioned, there was clear mandate by authorities that DTA and SEZ has to be segregated and no exchange can take place without their clearance. Added to that , post Kargil war, GOI made it mandatory that each refinery should have crude storage capacity of at least 28 days consumption.
As KP gained experience, he was given independent charge for tank farm execution but still CCE coordination was under me. That time Mr M Anbunathan was the CCE.
Additional Crude tanks
During DTA days though we had plot plan cleared for 14 crude oil tanks, we executed only 12 tanks in DTA period. But with Post Kargil mandate and addition of JERP we required 28 tanks. During my absence ( having gone to GIS) KP interfaced with the department and pleaded the case. The issue was the land space availability in MTF area! Somehow they worked out and got the layout cleared by using the space left when we conceived Ph1 layout but with 4M dyke wall height. As technical specialist I questioned CCE for that final decision from safety point. Then only he realized the involved issue of emergency escape though this height! But that relieved us from ensuring enough crude inventory storage at MTF.
Having got over the storage volume factor, then came the MOC(material of Construction as well as management of Change) for MVWS Fire water rings in MTF tanks. As the ring diameter were only 2" dia. using sea water, all the rings got corroded in 5 years time and needed change/ replacement. At the same time, there was requirement of potable water to be supplied to ships calling at Sikka port. As typical infrastructure project in-charge, I decided to combine both the issues and suggested to opt for 2X 4000M3 metal tanks for storing fresh potable water having 2X500 M3/hr transfer pumps. The idea is to use those pumps both for transferring water to jetty for supply to ships as well as to line fill the entire MTF fire water ring main with fresh water. The fundamental objective is to ensure only fresh water is used for initial throw through the rings and if the fire rage continue and the demand goes more than 1000M3/Hr in a spot, the main sea water FW pumps to cut in and fight the fire. This way we eliminated the header and rings getting corroded with sea water. The end user feed back says that they are relieved of the corrosion issue.
Then comes the big story of sea water transfer to refinery! As far as sea water in-take concerned, PMSP cleared the intake arrangement&pumps and placed the order on VA Tech for sea water filtration module using Lamella clarifier technology. But having faced major issue of epoxy coating of sea water transfer lines in DTA phase, the management thought of a difference!
