India’s pipeline and gas distribution infrastructure must operate safely across long distances, varied terrain, changing operating pressures and growing demand. Failures are costly not only in downtime, but in public safety, environmental impact, and reputational damage.
Our Integrity Management Studies, developed in alignment with PNGRB Integrity Management System (IMS) Regulations, help operators meet statutory obligations while maintaining safe, reliable, and efficient network performance.

What PNGRB Expects from Operators
Under PNGRB, operators are responsible for designing, maintaining, and operating their assets in accordance with:

- Integrity Management Regulations for Petroleum and Natural Gas Pipelines
- IMS requirements for City Gas Distribution Networks
- Pipeline safety rules, health monitoring, risk management and emergency preparedness
- Periodic audits, reviews, documentation, and governance systems
Our studies help organisations interpret these regulations into practical engineering actions.
Objective of PNGRB-Based Integrity Management
A compliant Integrity Management Program answers three critical requirements:
- Know the asset condition — where degradation or anomalies exist
- Manage the risk — prioritise inspection, mitigation and renewal
- Demonstrate compliance — documented procedures, audits, performance metrics
We help clients build programs that meet legal expectations while strengthening real-world reliability.
Typical Challenges Operators Face
We support clients who struggle with:
- Ageing buried pipelines and station assets
- Coating deterioration, CP inefficiencies and external corrosion
- In-line inspection findings without action prioritisation
- Intermittent data quality or incomplete records
- PNGRB audit observations requiring closure
- Lack of risk ranking and consequence evaluation
- Resource limitations during expansion phases

Our Integrity Study bridges these gaps with structured engineering analysis.
Our PNGRB-Aligned Integrity Management Services
We develop and implement Integrity Management frameworks rooted in PNGRB philosophy, supported by engineering and field experience.

Integrity Management Plan Development (PNGRB Compliant)
- Asset register creation and classification
- Criticality review based on service, environment and consequence
- Threat identification and risk assessment
- Inspection and monitoring strategy formulation
This forms the backbone of operator compliance.
Risk Assessment and Ranking
Using PNGRB methodology, failure consequences and likelihoods are evaluated to determine priority locations for:
- Patrolling
- Surveys
- Maintenance
- Replacement decisions
Pipeline and CGD Network Integrity Assessment
We evaluate:
- Coating degradation
- External corrosion
- CUI in terminal piping
- CP system health
- IMP compliance gaps
- Third-party activity risk
ILI / Survey Data Interpretation
We help operators translate ILI and survey data into:
- Remaining life
- Repair plans
- Risk adjustments
- Integrity dashboard updates
Performance Indicator and KPI Framework
PNGRB emphasises governance through measurable performance parameters.
We design KPIs that:
- Track integrity system effectiveness
- Meet PNGRB reporting expectations
- Improve decision-making
Emergency and Damage Prevention Elements
Our study reviews:
- Leak response capability
- Excavation / third-party interference management
- Reliability of isolation arrangements
- Depth-of-cover adherence
Integrity Operating Window (IOW) Definition
Based on operating pressure, gas quality, corrosivity, and environmental factors, we define limits and monitoring logic to sustain safe operation.
Gap Assessment and IMP Audit Preparedness
Before PNGRB audits, we help operators:
- Identify compliance gaps
- Map improvement actions
- Establish documentation trails
- Prepare stakeholders for verification
Deliverables You Receive
A PNGRB-oriented integrity study typically provides:
- Integrity Management Plan documentation
- Threat and risk register
- Inspection planning sheets
- Repair/maturity action plan
- KPI framework
- Remaining life recommendations
- Training and awareness modules
- Audit Review notes and closing strategy
This gives operators the ability to demonstrate compliance and make informed maintenance decisions.
Industries & Assets Covered
We support Integrity Management for:
- Cross-country gas pipelines
- CGD distribution and steel network
- City gate stations
- LNG receiving and distribution terminals
- CNG compression stations
- Regulating and metering stations
- Pipeline utilities and receiving facilities
Our Edge – Why Operators Choose iFluids
- Understanding of PNGRB regulatory structure and intent
- Multi-disciplinary engineering capability (process, pipeline, CP, corrosion, operations)
- Field experience across gas infrastructure projects
- Practical gap-closing guidance, not paperwork
- Support during inspections, audits, expansions and shutdowns
We help operators move from compliance anxiety to assured, evidence-backed governance.
Strengthening PNGRB Integrity Management often requires support from other key process safety studies. Depending on the asset condition and regulatory expectations, organisations may also benefit from structured PHA Studies ↗ such as HAZID, HAZOP, Bow-Tie Analysis and QRA, which help refine threat identification and consequence evaluation.
For facilities that require deeper evaluation of fire, explosion or survivability controls, our Technical Safety Studies ↗ (FERA, EERA, TRIA, Toxic Risk Assessment, Fire Protection Studies) provide the detailed engineering needed to close safety gaps highlighted during Integrity Reviews.
Where shutdown logic, emergency isolation or functional layers of protection must be validated, our Functional Safety Studies ↗ including SIL Assessment, SIL Verification and ALARP Demonstration help ensure that SIFs and emergency systems perform as intended.
Operators seeking to improve organisational safety readiness can further leverage our Safety Audits ↗ (IS 14489 / OISD / Fire / Electrical / Chemical) uprating and engineering modifications identified during PNGRB gap assessments.
Together, these complementary services create a robust, end-to-end framework supporting safe operations, regulatory compliance and continuous improvement under the PNGRB Integrity Management philosophy. To explore our complete suite of engineering and process safety services, you may also view our detailed iFluids brochure.
When Do PNGRB Guidelines Require Integrity Review?
- Before new pipeline commissioning
- After major modifications
- During expansions or uprating
- When ILI reveals anomalies
- Following incidents or leak events
- Ahead of regulatory audits
- During annual IMS reviews
If any of these situations applies, an Integrity Study ensures readiness and compliance.
Example Insight
One CGD operator used our risk-prioritised review to restructure inspection strategy, improving reliability while reducing unnecessary patrolling by 25%.

Frequently Asked Questions
It is a structured evaluation of pipelines, CGD networks and associated facilities, conducted in line with PNGRB Integrity Management System regulations. The study assesses conditions, identifies threats, ranks risk, and recommends actions required for safe and compliant operation.
Any company operating cross-country pipelines, CGD systems, city gate stations, terminals, CNG stations or LNG facilities falls under PNGRB’s IMS requirements and must maintain a documented Integrity Management Program.
PNGRB recommends a likelihood-versus-consequence approach so operators can prioritise inspection, mitigation and repair actions where the highest safety and performance risk exists.
It improves visibility on asset condition, prevents failures, supports life extension, reduces unnecessary inspections, optimises maintenance cost, and strengthens shutdown readiness not just compliance fulfillment.
You receive a threat register, risk ranking sheets, prioritised inspection/repair plan, remaining life insights, operating window limits, KPI framework, action roadmaps, and documentation support for audit readiness.
Typically annually and whenever expansions, uprating, incidents, ILI findings or operational changes occur ensuring that risk and integrity controls remain aligned with the system condition.
Yes. Gap assessments, procedure revision, KPI alignment, record creation and action tracking help demonstrate compliance and resolve audit comments effectively.
