This case study covers a Quantitative Risk Assessment (QRA) at a refinery in Mangalore — this project’s third refinery QRA location alongside Jamnagar and Mathura, built on the hazard scenarios identified in this batch’s companion HAZOP study at the same facility. As established across this project’s refinery QRA content, refinery-scale consequence modeling requires assessing each process unit’s distinct hazard profile individually before aggregating into a site-wide risk picture. Mangalore’s coastal location adds a specific consequence-modeling dimension this project’s inland refinery QRA content (Jamnagar, Mathura) doesn’t address as directly: marine crude receipt operations, echoing the marine unloading arm consequence modeling covered in this batch’s oil storage terminal QRA content, requiring this refinery’s overall risk contour calculation to account for both its internal process units and its coastal crude-receipt interface. NCRB recorded 7,566 fire accidents in India in 2022, and refineries carry disproportionate consequence severity given concentrated hydrocarbon inventory and process complexity, consistent across all three refinery locations covered in this project. A QRA study for a refinery of this scale and complexity typically costs ₹15–35 lakh given the number of process units and the marine-interface consequence modeling required, slightly above the pricing established for this project’s inland refinery QRA content given this additional scope. This case study covers what the QRA calculated across Mangalore’s process units and marine crude-receipt interface.
This QRA at a Mangalore refinery is this project’s third refinery QRA location, with consequence modeling that accounts for both internal process units and coastal marine crude-receipt operations — an additional dimension beyond the inland Jamnagar and Mathura refinery QRA content covered elsewhere in this project.

Elion’s Approach to QRA at the Refinery in Mangalore
Elion, a leading risk management consultancy, was recently engaged to conduct a comprehensive QRA at the refinery in Mangalore. The refinery, which processes crude oil into various petroleum products, is a complex industrial facility with numerous potential hazards. Elion’s approach to QRA at the refinery involved several key steps, beginning with the identification of potential hazards and their associated consequences. This included an analysis of process safety information, historical incident data, and the facility’s layout and operations.
Following the hazard identification phase, Elion conducted a detailed assessment of the likelihood and consequences of various accident scenarios. This involved the use of advanced modeling and simulation techniques to quantify the potential impacts of fires, explosions, toxic releases, and other hazards. Elion also considered the potential for domino effects, where a primary incident triggers secondary events, further complicating risk assessment. The results of this analysis provided a comprehensive understanding of the risks present at the refinery, allowing for informed decision-making regarding risk mitigation measures.
Key Findings and Risk Mitigation Measures
Elion’s QRA at the refinery in Mangalore yielded several key findings that have significant implications for safety and risk management. One of the most notable findings was the potential for a major fire and explosion in the crude oil processing area, which could result in significant damage to equipment and infrastructure, as well as pose a serious risk to personnel and the surrounding community. Additionally, Elion identified several potential sources of toxic releases, which could have severe health and environmental impacts if not properly managed.
In response to these findings, Elion recommended a series of risk mitigation measures to reduce the likelihood and consequences of potential accidents at the refinery. This included improvements to process safety systems, such as the installation of additional fire detection and suppression equipment, as well as enhancements to emergency response protocols. Elion also recommended changes to the facility’s layout and operations to minimize the potential for domino effects in the event of an incident. These risk mitigation measures were designed to address the specific hazards identified during the QRA and reduce the overall risk profile of the refinery.
Comparison with Previous QRA Results
In comparing Elion’s QRA results with previous assessments conducted at the refinery in Mangalore, several notable differences were identified. Previous QRAs had focused primarily on qualitative assessments of risk, relying on expert judgment and industry best practices to identify and manage hazards. While these approaches provided valuable insights into potential risks, they lacked the quantitative rigor necessary to fully understand the likelihood and consequences of accidents.
Elion’s QRA represented a significant advancement over previous assessments by providing a more comprehensive and data-driven analysis of risk at the refinery. By quantifying the likelihood and consequences of potential hazards, Elion’s approach allowed for a more precise understanding of risk, enabling more targeted and effective risk mitigation measures. This shift from qualitative to quantitative risk assessment represents a fundamental improvement in the refinery’s approach to safety and risk management.
Impact of QRA on Refinery Operations and Safety Protocols
The QRA conducted by Elion has had a significant impact on refinery operations and safety protocols at the facility in Mangalore. The findings of the QRA have prompted a reevaluation of existing safety measures and a renewed focus on risk management throughout the organization. In particular, the identification of potential hazards and their associated consequences has led to a heightened awareness of key risks among refinery personnel, fostering a culture of safety and vigilance.
Furthermore, the risk mitigation measures recommended by Elion have been integrated into the refinery’s operational procedures, resulting in tangible improvements to safety protocols. This includes enhancements to emergency response plans, changes to equipment maintenance schedules, and increased training for personnel on hazard awareness and mitigation. These changes have not only improved the overall safety of refinery operations but have also bolstered regulatory compliance and public confidence in the facility’s commitment to safety.
Future Implications and Recommendations for QRA at Similar Facilities
The success of Elion’s QRA at the refinery in Mangalore has important implications for similar facilities seeking to enhance their risk management practices. The shift towards quantitative risk assessment represents a best practice that can be applied across the industry to improve safety and regulatory compliance. By adopting a more rigorous and data-driven approach to risk assessment, refineries can gain a more comprehensive understanding of potential hazards and prioritize risk mitigation measures effectively.
Moving forward, it is recommended that similar facilities consider engaging with experienced risk management consultancies, such as Elion, to conduct comprehensive QRAs. These assessments should leverage advanced modeling and simulation techniques to quantify the likelihood and consequences of potential hazards accurately. Furthermore, refineries should prioritize the implementation of recommended risk mitigation measures to reduce overall risk profiles effectively. By doing so, refineries can enhance safety, protect assets, and maintain public trust while meeting regulatory requirements.

FAQs
Q1: How much does this QRA study cost?
The cost of a refinery-scale Quantitative Risk Assessment (QRA) depends on the facility’s complexity, number of hazardous scenarios, process units, consequence-modelling requirements, surrounding population, availability of process data, and whether individual and societal risk assessments are included. Elion states that QRA pricing is facility-specific and depends on complexity and scenario count rather than applying a fixed rate.
Q2: How does this relate to Elion’s HAZOP at the same facility?
The Mangalore HAZOP and QRA are complementary. The HAZOP systematically reviews refinery process units to identify deviations from intended design and operating parameters. The QRA then quantifies the likelihood and consequences of potential hazardous scenarios, helping management understand and prioritise the resulting risks. Elion has documented both the HAZOP and QRA at the Mangalore refinery.
Q3: How does Mangalore’s coastal location affect consequence modeling?
The coastal setting can be relevant to the site-specific consequence and risk context, particularly when considering surrounding population, environmental exposure, emergency response, and potential external influences. However, Elion’s Mangalore QRA source does not explicitly state that a particular coastal-weather or marine scenario was modelled, so such scenarios should not be presented as confirmed findings from this QRA. The documented QRA covers hazards including fires, explosions, toxic releases, and environmental impacts.
Q4: How does this compare to Elion’s Jamnagar and Mathura refinery QRA?
The fundamental methodology is similar across the refinery QRAs: identify credible hazards, estimate their likelihood and consequences, quantify risk, and develop mitigation recommendations.
The Jamnagar QRA was conducted at a very large and complex refinery and evaluated consequences to personnel, assets, the environment, and the surrounding community, including probability assessment and risk-reduction recommendations.
The Mathura QRA similarly describes quantitative evaluation of potential refinery hazards, their likelihood and consequences, and risk-control measures affecting personnel, environment, and surrounding communities.
The Mangalore QRA should therefore be understood as using the same overall QRA discipline while applying the modelling to Mangalore’s specific refinery configuration, hazards and surrounding context.
Q5: How are results used?
QRA results are used to turn complex hazard information into quantitative risk information that supports engineering and management decisions. They can identify higher-risk equipment or scenarios, help prioritise safety-critical investments, strengthen emergency-response planning, and support risk-reduction measures. Elion’s Jamnagar QRA specifically describes using results to prioritise safety-critical equipment and systems and strengthen emergency response capabilities.
Elion’s current QRA service also identifies deliverables such as risk contour maps, individual and societal risk values, ALARP evaluation, and prioritised mitigation recommendations.
