Risk Analysis
Having been relieved from Project Management responsibility, my focus and attention got concentrated in finding optimized solutions to meet ALARP in upcoming projects of Reliance.
Though I had practical experience in handling loss prevention measures for all upcoming projects, this new subject handling gave me thrill !
Started closely interacting with M/S TV Venkateswaran &Prashanti Bupathy of CHSEE to learn the nuances of risk analysis. They gave me lot of study material for developing logic for arriving at
RISK MATRIX and detailed picture about LOPA (Layer of Protection Analysis). They briefed me about the benefits of carrying out Consequence Analysis and what way it is different from total QRA
(Quantitative Risk Analysis). They went to the extent of training me with Hazop Study procedure and how it should be developed before actually going into hazop for any project/plant and how the
ALARP achievable mitigation measures are identified etc.
Since I am still considered as project management personnel, the insurance group and under writer technical team pose several challenging tasks while reassessing some of the manufacturing locations cover. One such case was - EO drums in MEG plant at DMD facing the upcoming CPP-power plant
in DMD (Dahej). After discussions with Mr. Paul Nicholson of M/S Marsh to understand the specific issue, I took the services of CHSEE team to carry out the consequence analysis to arrive at the risk assessment.The Hazard Identification was done based on Safety Review Checklist, Incident data
for EO bullets,Fire&Explosion Index method. These were the input factors for carrying out the consequence analysis &then Dispensing Modelling was done using Process Hazard Analysis Software tool. The Risk Rating was done based on the onsite &offsite impacts of the scenario, considering the probable frequency of occurrence of the said risk, Importantly the wind rose data
and actual population density prevalent in that axis and area were incorporated in that dispersion model. As Reliance is in the advanced mode for Safety Consciousness, we do possess PHAST Risk software, a tool developed by M/S DNV. Using that tool, we could arrive at the calculated risk associated with that EO storage and developed Risk Contours, F-N curves &contributor to risks.
The beauty was that we could conclude that the existing condition was Safe since the bullet/s dished ends were not facing the power plant being built opposite across with an inter-distance of more than 100 M..We could proudly present the report to insurance authorities and convinced them.
Rather this study helped us to establish and assure the management that we have in-house capability to address these sort of challenges.
Having succeeded that challenge, that became the start reference for locating any occupied buildings
in any of the new projects in Reliance. These were done for locating the common control room of PTA 5&6 at DMD, freezing the inter-distance for PIBs within the cracker complex (ROGC) in JMD J3 for studying the explosive impact due to C2/C3 leak, locating the PIBs within Gasification Complex both DTA and SEZ.for the Syn.gas &Hydrogen impact.
Having been introduced in Risk Analysis, participated in Synthesized Natural gas Hazop studies and SIL assessment at UK. Though not directly attached with J3 execution, my role assumed importance in Safety studies of all projects under implementation.
