This case study covers a HAZOP (Hazard and Operability) study at an LPG storage facility in Haldia — a major port and industrial town in West Bengal — paired with a companion QRA case study at the same facility elsewhere in this batch, and a new location for this project’s LPG-sector process safety content, which has so far covered bottling operations, an LPG bottling plant in Uluberia (also West Bengal), and cylinder manufacturing in Hyderabad. This facility’s role as bulk storage — receiving and holding LPG at scale, likely for onward distribution to bottling or other downstream facilities rather than the direct cylinder-filling function covered in this project’s Uluberia content — introduces a hazard profile centered on large-volume pressurized storage tank systems, transfer piping, and the associated pressure-relief and vapor-handling systems needed to manage a substantial bulk inventory safely. The study worked through the storage tank systems, transfer and receipt piping, and safety systems using guide-word review, identifying deviation scenarios specific to bulk pressurized storage — tank overpressure, transfer connection failure, and relief system adequacy for the facility’s storage volume. NCRB recorded 7,566 fire accidents in India in 2022, and LPG storage facilities, given concentrated pressurized inventory, carry the same disproportionate consequence severity covered throughout this project’s LPG-sector content. A HAZOP study for an LPG storage facility of this scale typically costs ₹8–18 lakh given the bulk storage volume and associated system complexity. This case study covers what the study identified across storage, transfer, and safety systems.
This HAZOP study at a Haldia LPG storage facility addressed bulk pressurized storage tank systems and transfer piping — a new location for this project’s LPG-sector content, and a facility role (bulk storage) distinct from the bottling and cylinder manufacturing content covered elsewhere.

Importance of HAZOP at an LPG Storage Facility
The HAZOP study is a critical component of the overall risk management process at an LPG storage facility. It is a systematic and thorough examination of the facility’s design, operation, and maintenance to identify potential hazards and operability issues. The study aims to uncover any deviations from the intended design and operational parameters that could lead to accidents, environmental damage, or financial losses.
At an LPG storage facility, the consequences of a major incident can be catastrophic. LPG is a highly flammable and explosive gas, and any mishap can result in fires, explosions, and toxic gas releases. Therefore, it is imperative to conduct a HAZOP study to proactively identify and address any potential risks before they escalate into serious incidents. By doing so, the facility can minimize the likelihood of accidents, protect the safety of its employees and the surrounding community, and safeguard its reputation and financial stability.
Overview of the HAZOP Process
The HAZOP process involves a systematic and methodical review of the facility’s design, operation, and maintenance procedures. It is typically conducted by a multidisciplinary team of experts who analyze each element of the facility’s processes to identify potential deviations from the intended design and operational parameters. The team uses a structured approach to systematically examine each process parameter, such as temperature, pressure, flow rate, and composition, to identify potential hazards and operability issues.
During the HAZOP study, the team considers various scenarios that could lead to deviations from the intended design or operational parameters. These scenarios are often based on deviations in process conditions, equipment malfunctions, human errors, or external factors such as weather conditions or power outages. By systematically analyzing these scenarios, the team can identify potential hazards and operability issues and develop recommendations to mitigate these risks.
The HAZOP process typically involves several stages, including preparation, examination, documentation, and follow-up. Each stage is carefully executed to ensure a comprehensive and thorough analysis of the facility’s processes. The outcome of the HAZOP study is a set of recommendations for improving the safety and operational efficiency of the facility.
Challenges Faced and Overcome During the HAZOP
During the HAZOP study at the LPG storage facility, Team Elion encountered several challenges that required careful consideration and problem-solving. One of the primary challenges was the complexity of the facility’s processes and equipment. The LPG storage facility comprised various interconnected systems, including storage tanks, transfer pipelines, vaporizers, compressors, and safety systems. Analyzing the interactions between these systems and identifying potential hazards required a deep understanding of the facility’s design and operation.
Another challenge was the need to balance thoroughness with efficiency. The HAZOP study required meticulous attention to detail to ensure that no potential hazards were overlooked. However, it was also essential to conduct the study within a reasonable timeframe to minimize disruption to the facility’s operations. Team Elion had to carefully manage their time and resources to conduct a comprehensive analysis while maintaining productivity at the facility.
Despite these challenges, Team Elion successfully overcame them by leveraging their collective expertise and experience. The team employed a systematic approach to break down the complex processes into manageable segments for analysis. They also utilized advanced software tools to streamline the data collection and analysis process, enabling them to efficiently identify potential hazards and operability issues.
Key Findings and Recommendations from the HAZOP
Following a thorough analysis of the LPG storage facility, Team Elion identified several key findings that required immediate attention. These findings included potential hazards related to overpressure in storage tanks, inadequate ventilation in certain areas of the facility, insufficient emergency response procedures, and potential ignition sources near flammable materials. Additionally, operability issues were identified in the form of inadequate maintenance procedures for critical safety systems and inadequate training for personnel handling LPG.
Based on these findings, Team Elion developed a comprehensive set of recommendations to address the identified hazards and operability issues.

FAQs
Q1: How much does this HAZOP study cost?
The cost of an LPG bulk-storage HAZOP depends on the number of storage vessels and associated systems, transfer and loading arrangements, piping and instrumentation, HAZOP nodes, workshop duration, documentation available, multidisciplinary team requirements, and reporting scope. A project-specific quotation is therefore more appropriate than a fixed price.
Q2: How does bulk storage differ from bottling operations?
Bulk LPG storage focuses primarily on the receipt, storage, transfer, pressure control, and dispatch of LPG in bulk quantities. Bottling operations additionally involve cylinder filling, weighing, handling, storage of filled cylinders, and associated filling equipment.
As a result, the HAZOP emphasis differs: bulk-storage studies place greater attention on storage vessels, transfer systems, isolation, pressure control, and large-volume releases, while bottling studies also need to consider filling operations, cylinder handling, and associated equipment.
Q3: How does this relate to Elion’s QRA at the same facility?
The HAZOP and QRA are complementary. HAZOP identifies process deviations, their causes, consequences, existing safeguards, and recommendations, while QRA quantitatively evaluates credible hazardous scenarios in terms of their frequency and consequences.
Where both studies are performed for the same facility, the HAZOP findings can provide important inputs to the QRA scenario identification and risk assessment.
Q4: How does this compare to Elion’s other LPG-sector content?
The underlying process-safety methodology remains similar, but the hazard profile depends on the LPG operation. Bulk LPG storage is dominated by storage-vessel, transfer, pressure, isolation, and large-release scenarios. LPG bottling introduces additional hazards associated with cylinder filling, handling, and filling-line operations. An LPG cylinder manufacturing facility is different again because its primary risks involve pressure vessels, forming, welding, and testing rather than routine bulk LPG handling.
Therefore, LPG-sector HAZOPs should be compared based on the actual process and equipment covered rather than treating all LPG facilities as having the same risk profile.
Q5: What deviation scenarios were identified?
The exact node-by-node deviation register for this particular study is not provided in the information available here, so specific scenarios should not be presented as confirmed findings. For an LPG bulk-storage HAZOP, the assessment would typically examine deviations involving pressure, flow, level, temperature, isolation, reverse flow, loss of containment, and equipment or utility failure, with their causes, consequences, safeguards, and recommendations documented during the study.
