The 1962-commissioned Missamari depot’s main function is to transport MS, SKO, HSD, and ATF from the Guwahati Refinery, Betkuchi, and Lumding terminals via tank trucks and distributing them to the Army, Air Force, GREF, BRO, and few other retail stores and private parties in Assam and Arunachal Pradesh. For the Missamari IOCL POL facility in Assam, IOCL has entrusted iFluids Engineering to conduct the HAZOP (Hazard & Operability) study.
The HAZOP (Hazard & Operability) study’s objective is to lessen the likelihood by reducing the probability and consequences of an incident and evaluate effects of an occurrence that would have a negative impact on the people, facility, properties, and the environment.
Missamari Depot situated inside Missamari Military cantonment at Missamari Town, Dist. Sonitpur, Assam, is at a distance of 40 Km from the District Headquarter Tezpur. Commissioned in the year 1962, the major function of the depot is to receive MS, SKO, HSD and ATF from Guwahati Refinery, Betkuchi & Lumding terminals by road through tank trucks and distribute to Army, Air-Force, GREF, BRO & some other retail outlets & private parties of Assam & Arunachal Pradesh. The Quantitative risk assessment study for Missamari IOCL POL depot, Assam, had been carried out by iFluids Engineering for IOCL.
The facilities covered under the QRA study for the Project are given below.
- Tank Lorries for Receipt of products.
- Storage tanks of adequate capacities for storage purposes.
- The Loading Facilities for products into tank lorries, Ex.Through loading arms
Evaluation of the potential risk levels for personnels due to accidental release of hazardous materials from loss of containment scenarios from the facilities and exemplification of individual risks that are within the broadly acceptable regions is the main objective of this study.
To meet the above objective of the study, Identification and evaluation of potential scenarios had been carried out and the chances of consequences related to potential accidental releases occurring in the facility were exhibited.
The Objectives of QRA are as follows:
- Discovering Major Hazards and Loss of Containment (LOC) scenarios
- Computing the physical effects of failure case scenarios that includes Estimation of fire results such as Jet Fire, Pool Fire and Flash Fire alongside with Overpressure Explosion.
- To Compute the failure frequency of the facility.
- To Elucidate the societal risk and to rate the Potential loss of Life.
- To Bring about a risk assessment to confirm that the risk mitigation can be consistent with the ALARP principle according to the UK HSE risk acceptance criteria
To Endorse risk reducing measures to make sure that all risks are in ALARP or in Acceptable region
