This case study covers a HAZOP (Hazard and Operability) study for a petroleum pipeline in Gujarat — a genuinely new asset type for this project’s process safety content, distinct from every fixed-site facility (refineries, terminals, processing plants, storage depots) covered elsewhere in this project. A pipeline HAZOP requires a fundamentally different node structure than a fixed-site facility review: rather than dividing a facility into process units by function (distillation, compression, storage), a pipeline HAZOP divides the route into segments based on factors like elevation change, population density along the route corridor, crossing points (roads, railways, waterways), and pump or valve station locations, since the hazard profile at any given point along a long linear asset depends heavily on what’s specifically at that location rather than a uniform risk applying across the entire route length. Third-party interference (excavation damage, unauthorized tapping) is a hazard category specific to pipeline HAZOP without a direct equivalent in this project’s fixed-site facility content, given how much a buried or exposed pipeline route traverses land not under the pipeline operator’s direct control, unlike a fenced, access-controlled facility site. The study worked through the pipeline’s route segments, pump and valve stations, and crossing points using guide-word review adapted to this linear-asset structure, identifying deviation scenarios specific to pipeline operation — pressure surge propagation along the line length, corrosion-related integrity loss at specific route segments, and third-party interference risk varying by route population density and land use. NCRB recorded 7,566 fire accidents in India in 2022, and petroleum pipelines, given their length and the variable population density and land use they traverse, present a risk profile that doesn’t concentrate at one point the way a fixed-site facility’s risk does, requiring this segment-by-segment review approach. A HAZOP study for a petroleum pipeline of this scale typically costs ₹15–35 lakh given the route length and number of segments requiring individual review. This case study covers what the study identified across the pipeline’s route segments and stations.
This HAZOP study for a Gujarat petroleum pipeline required a genuinely different node structure than every other facility covered in this project’s process safety content — dividing a route into segments by elevation, population density, and crossing points rather than a fixed site into functional process units, and addressing third-party interference risk with no direct equivalent at a fenced, access-controlled facility.

FAQs
Q1: How much does this HAZOP study cost?
The cost of a pipeline HAZOP study depends on pipeline length, number of HAZOP segments or nodes, process complexity, associated stations and facilities, available P&IDs and route information, workshop duration, multidisciplinary team requirements, and reporting scope. A project-specific quotation is therefore more appropriate than applying a fixed price.
Q2: How does pipeline HAZOP differ from facility HAZOP?
A pipeline HAZOP focuses on the pipeline as a linear asset and systematically reviews sections of the route for deviations from intended operating conditions. It considers parameters such as flow, pressure, temperature, direction, containment, isolation, and interaction with external activities.
A facility HAZOP generally focuses on process equipment and interconnected systems within a defined plant boundary, where equipment, process units, instrumentation, utilities, and operating interfaces can be reviewed node by node.
Q3: How does this relate to Elion’s QRA at the same asset?
The two studies are complementary. HAZOP identifies deviations, causes, consequences, safeguards, and recommendations, while QRA takes credible hazardous scenarios and evaluates their likelihood and consequences quantitatively.
For a pipeline, HAZOP findings can help identify scenarios such as loss of containment, abnormal pressure or flow, isolation failure, or external interference that may subsequently be evaluated within the QRA.
Q4: What is third-party interference risk?
Third-party interference refers to damage or threats caused by activities outside the pipeline operator’s direct control, such as excavation, construction, road works, agricultural activity, unauthorized digging, or other work near the pipeline route.
It is particularly important for pipelines because a buried pipeline can be damaged by excavation or other external activity even when its process and mechanical systems are operating normally. HAZOP or risk assessment can therefore consider route protection, marking, monitoring, communication with third parties, and permit-to-work controls where applicable.
Q5: How is a pipeline route divided into HAZOP segments?
A pipeline is typically divided into logical, reviewable segments based on changes in operating conditions, equipment, isolation points, flow direction, line configuration, or significant external interfaces.
Typical boundaries may include:
- Pipeline sections between major isolation valves
- Changes in diameter, pressure, or service
- Pumping, compressor, metering, or regulating stations
- Branch connections and major tie-ins
- River, road, or other significant crossings
- Sections with materially different surrounding conditions
The objective is to create segments that are sufficiently specific for meaningful deviation analysis without making the HAZOP unnecessarily fragmented.
