BKPL pipeline of Indian Oil Corporation Limited originates at Barauni Refinery. The pipeline transports varieties of products, namely MS, HSD, SKO, Premium Grade MS and Extra Mile HSD. Main pumping station is Barauni, pumping is also done at Patna, Mugalsarai & Allahabad. There are tap off point at Patna, Mugalsarai & Allahabad while the two terminal station are located at Kanpur and Lucknow. Product of Haldia & Barauni Refinery are delivered to the terminals located at Patna, Mugalsarai & Allahabad, Lucknow & Kanpur.
The Scope of this study is to carry out Quantitative Risk modelling for Allahabad Pumping station and Kanpur terminal.
The main objective of this study is to evaluate the potential risk levels for personnel due to accidental release of hazardous materials from loss of containment scenarios from the facilities and to demonstrate that individual risks are within the broadly acceptable regions. The Objectives of QRA are as follows:
- Identification of the Hazards involved and possible failure scenarios for pumping station and Terminal.
- Calculation of physical effects of failure case scenarios which include Estimation of Jet Fire, Pool Fire heat radiation distances, Flammable gas dispersion distances, and overpressure explosion distances.
The selection of initiating events and incidents should consider the goals or objectives of the study and the data requirements. The data requirements increase significantly when non -accident – initiated events are included and when the number of release size increase.
While the potential range of release sizes is tremendous, groupings are both appropriate and necessitated by data restrictions. The main reasons for including release sizes other than the catastrophic are to reduce the conservatism in an analysis and to better understand the relative contributions to risk of small versus large releases.
In Risk Analysis studies contributions from low frequency – high outcome effect as well as high frequency – low outcome events are distinguished. The objective of this study is emergency planning. Only holistic & conservative assumptions are used for obvious reasons. Hence, even if the outcomes may look pessimistic, the planning for emergency concept should be borne in mind whilst interpreting the results.
