This case study covers a Quantitative Risk Assessment (QRA) at an LPG storage facility in Haldia — the same facility covered by this batch’s companion HAZOP study, with the bulk-storage-specific deviation scenarios identified there feeding into this QRA’s numerical risk calculation. As explained in that companion HAZOP case study, this facility’s bulk storage role introduces consequence-modeling considerations distinct from bottling or cylinder manufacturing: a large-volume tank failure or transfer connection failure releases substantially more inventory than a single cylinder-filling incident, meaning consequence modeling here needs to account for a larger potential vapor cloud and jet fire scenario scale than the smaller-inventory incidents modeled at this project’s bottling and manufacturing facility content. Haldia’s status as a port and industrial town means this facility likely sits within a broader industrial cluster, adding a proximity consideration to surrounding industrial and possibly residential development similar in principle to the societal risk weighting covered in this project’s other LPG facility QRA content. NCRB recorded 7,566 fire accidents in India in 2022, and bulk LPG storage facilities, given their large concentrated inventory, warrant the same systematic quantitative risk assessment applied to this project’s other pressurized gas infrastructure content. A QRA study for an LPG storage facility of this scale typically costs ₹10–22 lakh given the bulk storage volume involved. This case study covers what the QRA calculated across the facility’s storage and transfer systems.
This QRA at a Haldia LPG storage facility modeled larger-scale vapor cloud and jet fire consequence scenarios than the bottling and cylinder manufacturing content covered elsewhere in this project, given how much more inventory a bulk storage tank failure releases compared to a single cylinder-filling incident.

FAQs
Q1: How much does this QRA study cost?
The cost of an LPG bulk-storage Quantitative Risk Assessment (QRA) depends on the storage capacity, number and type of LPG vessels, transfer and loading systems, hazardous scenarios, consequence-modelling requirements, surrounding population, data availability, and reporting scope. A project-specific quotation is therefore more appropriate than a fixed price.
Q2: How does this relate to Elion’s HAZOP at the same facility?
The HAZOP and QRA are complementary. The HAZOP identifies deviations, causes, consequences, safeguards, and recommendations, while the QRA evaluates credible hazardous scenarios quantitatively by considering their likelihood and consequences. HAZOP findings can therefore provide important inputs for identifying QRA scenarios.
Q3: Why does bulk storage carry larger consequence scale?
Bulk LPG storage can involve large inventories of LPG concentrated in storage vessels. If a significant loss of containment occurs, a larger quantity of flammable material can potentially be released compared with smaller-scale handling or filling operations. Depending on the release and ignition conditions, this can produce substantial fire, explosion, or thermal-radiation consequences.
The consequence scale therefore depends not simply on the fact that the facility is a bulk-storage site, but on inventory, release characteristics, equipment configuration, isolation, safeguards, and surrounding exposure.
Q4: How does this compare to Elion’s other LPG-sector QRA content?
The fundamental QRA methodology remains similar across LPG facilities: identify credible scenarios, estimate their frequencies, model consequences, and evaluate individual and societal risk.
The emphasis varies by facility type:
- Bulk LPG storage: large storage inventories, transfer systems, vessels, and large-release scenarios.
- LPG bottling: storage and transfer combined with cylinder filling and handling operations.
- LPG cylinder manufacturing: primarily pressure-vessel manufacturing, welding, and pressure-testing risks rather than routine bulk LPG handling.
Therefore, the QRA scenario set should be tailored to the actual LPG process and inventory rather than copied between facility types.
Q5: How are results used?
QRA results are used to support risk-informed engineering and management decisions. They can help identify higher-risk scenarios, evaluate whether existing safeguards provide adequate risk reduction, prioritise additional protection measures, support emergency planning, and guide investment toward the areas that provide the greatest risk reduction.
