PESO Centralizes CNG & LNG Tank Approvals for Mobile Pressure Vessels

Introduction: Streamlining Fuel Tank Safety Approvals in India

In a move to simplify and standardize safety regulations, the Petroleum and Explosives Safety Organization (PESO) has issued a new directive centralizing the approval process for CNG and LNG fuel tanks used in mobile pressure vessels. With the growing adoption of natural gas-based mobility, PESO aims to ensure uniform enforcement and enhanced safety by delegating the approval responsibility solely to the Chief Controller of Explosives.

This PESO CNG LNG Approval update marks a significant change for manufacturers and importers of gas-based fuel systems.

Background: Why Centralization Was Needed

Previously, approvals for design drawings and specifications of fuel tanks used in mobile pressure vessels were granted by various zonal offices of PESO. However, this led to:

Inconsistent interpretations of standards
Delays in processing across regions
Variations in enforcement practices
Compliance gaps affecting safety

To eliminate these issues, PESO centralized the approval of designs for CNG and LNG fuel tanks under the jurisdiction of the Chief Controller of Explosives at Nagpur.

What the New Circular Directs

As per the circular:

All design and drawing approvals for CNG and LNG tanks used in mobile pressure vessels shall now be handled only by the Chief Controller.
Regional or zonal PESO offices will no longer process such applications.
This applies to:
- OEMs manufacturing gas vehicles
- Tank manufacturers and importers
- Companies retrofitting CNG/LNG tanks into vehicles

The PESO CNG LNG Approval must be obtained before commencing production, sale, or usage in commercial and industrial applications.

How This Impacts Stakeholders

Manufacturers:

Submit all technical drawings and documents directly to PESO HQ.
Ensure tank designs meet applicable Indian or international codes (e.g., ASME, ISO standards).
Prepare for longer lead times due to centralized queue.

Vehicle OEMs and Retrofitters:

Confirm tank models are pre-approved by PESO HQ.
Avoid using unverified components to prevent enforcement action.

End Users:

Gain better assurance of tank safety and regulatory compliance.
Benefit from uniform inspection and testing norms.

Expected Benefits of Centralized Approval

Faster resolution of safety issues
Reduced interpretation errors across regions
Standardized documentation and review processes
Better traceability and database maintenance
Increased public safety and industry confidence

This shift supports India’s broader goal of promoting safe, clean, and scalable natural gas infrastructure.

Action Required by Manufacturers

To comply with the updated PESO CNG LNG Approval process:

Submit applications to the Chief Controller at PESO HQ, Nagpur.
Include:
- Design drawings
- Material specifications
- Stress and safety analyses
- Manufacturing standards
Wait for official approval before:
- Importing
- Supplying
- Installing tanks in mobile applications

Failing to follow the revised protocol could result in license suspension, product seizure, or other legal consequences.

Conclusion: A Step Toward Safer Gas-Based Mobility

PESO’s centralization of CNG and LNG tank approvals under the Chief Controller of Explosives is a forward-looking move aimed at strengthening regulatory oversight in the natural gas transport sector. With standardized designs, centralized documentation, and consistent enforcement, the new directive promises improved safety and transparency for all stakeholders.

The PESO CNG LNG Approval process is now streamlined—making compliance simpler while raising the bar for industry accountability.
