This case study covers a Quantitative Risk Assessment (QRA) at an LPG bottling plant in Visakhapatnam — the same facility covered by this batch’s companion HAZOP case study, with HAZOP-identified deviation scenarios feeding into this QRA’s numerical risk calculation, consistent with the sequential relationship covered across this project’s other process safety content. LPG bottling plant QRA carries a specific consequence-modeling consideration many of this project’s other facility types don’t share as acutely: LPG bottling plants are frequently located closer to residential and commercial development than offshore platforms, refineries, or even aviation fuel depots, given the practical need to distribute filled cylinders efficiently to nearby markets, meaning societal risk calculations (which explicitly account for the number of people potentially affected by a given event) carry particular weight here relative to the individual risk calculations that might dominate a more isolated facility’s assessment. The assessment calculated risk contours across the bulk storage, pipeline, and cylinder-filling areas identified in the companion HAZOP study, modeling consequence scenarios specific to pressurized gas release — vapor cloud formation and potential ignition, jet fire from a pressurized leak — and comparing results against risk tolerability criteria with particular attention to the plant’s proximity to surrounding development. NCRB recorded 7,566 fire accidents in India in 2022, and LPG bottling plants combine the general fire risk baseline with the specific stakes of pressurized gas handling near populated areas. A QRA study for an LPG bottling plant of this scale typically costs ₹8–18 lakh. This case study covers what the QRA calculated and how the plant’s proximity to surrounding development shaped the risk-reduction priorities identified.
This QRA at a Visakhapatnam LPG bottling plant weighted societal risk particularly heavily, since LPG bottling plants are frequently located closer to residential and commercial development than offshore or refinery facilities — a proximity consideration that shapes risk-reduction priorities significantly.
