Urgent Submission Required: PESO Calls for Details on Modifications in Mobile Pressure Vessels

Introduction

The Petroleum and Explosives Safety Organization (PESO), under the Ministry of Commerce and Industry, has released a circular dated 24th July 2025, urging all fabricators of mobile pressure vessels licensed under Form LS-2 of SMPV(U) Rules to promptly submit details of any modifications or repairs. The move follows directives issued in a meeting chaired by the Secretary, DPIIT, to reinforce compliance, enhance safety, and bring transparency in the repair/modification practices across fabrication shops. This update underlines the significance of mobile pressure vessel compliance and mandates action within a tight one-week deadline.

Context: Why This Circular Matters

PESO’s circular references a prior communication dated 06.09.2022 concerning “Repair and modification in the existing mobile pressure vessels.” During the recent high-level meeting held on 30.06.2025, officials emphasized the importance of tracking any alterations made to mobile pressure vessels. This includes minor repairs or major structural modifications carried out at fabrication shops.

Such vigilance becomes necessary because:

Modifications can impact vessel integrity and operational safety.
Improper repairs might lead to pressure leaks, explosions, or regulatory violations.
Lack of documentation may hinder audits and legal accountability.

By instructing fabricators to submit these details, PESO ensures adherence to mobile pressure vessel compliance and strengthens overall regulatory control.

What Needs to be Submitted?

As per the circular, all mobile pressure vessel fabricators approved under the SMPV(U) Rules must:

Prepare a list of mobile pressure vessels that were modified or repaired after 06.09.2022.
Ensure the list includes work done within their fabrication shops.
Submit the report to PESO within one week of the circular’s issuance date (i.e., by 31st July 2025).

There is no allowance for delay or incomplete submission. Prompt and accurate compliance is essential to avoid future scrutiny.

Recipients and Forwarded Parties

The circular is directed to:

All mobile pressure vessel fabricators under SMPV Rules.

Additionally, it is forwarded for information to:

Shri Pritam Kumar, Under Secretary, DPIIT, New Delhi.
SIT committee members involved in pressure vessel safety governance.

This layered communication ensures oversight at multiple levels and emphasizes the regulatory priority of the subject.

Compliance Checklist for Fabricators

To help fabricators respond effectively, here is a quick checklist:

✅ Review all repair/modification activities post-06.09.2022.
✅ Document the vessel ID, nature of repair, date, and personnel involved.
✅ Validate the documentation with fabrication shop records.
✅ Submit the compiled list to PESO within one week.

Keeping clear records not only supports PESO’s inspection process but also protects the fabricator in case of future audits or incidents.

Conclusion: Mobile pressure vessel compliance

In light of PESO’s latest directive, all licensed mobile pressure vessel fabricators must act swiftly. The requirement to report repair or modification details is not merely administrative—it is a key part of ensuring structural safety, accountability, and compliance with the SMPV(U) Rules. The emphasis placed on this by the DPIIT and PESO reflects the government’s continued effort to reinforce safety across hazardous material transport systems. Ignoring the directive could lead to compliance risks and reputational damage. Staying updated with mobile pressure vessel compliance is now more crucial than ever.
