## Report on Amendment to the Static and Mobile Pressure Vessels Unfired Rules, 2016
**1. Executive Summary:**
This report analyzes an amendment to the Static and Mobile Pressure Vessels Unfired Rules, 2016, as published in the Gazette of India on April 15, 2025. The amendment focuses on incorporating specific standards and safety measures for pressure vessels used in hydrogen service, particularly concerning storage, transport, and material integrity. Key changes involve referencing ISO standards for hydrogen permeation, embrittlement testing, and valve requirements, as well as API standards for fitness-for-service assessments. These amendments appear intended to enhance the safety and reliability of pressure vessels handling hydrogen.
**2. Introduction:**
This report aims to provide an informative overview of the amendment to the Static and Mobile Pressure Vessels Unfired Rules, 2016, based solely on the provided official gazette notification. It outlines the changes introduced, their likely rationale, and the implications for affected stakeholders.
**3. Policy Overview:**
* The amendment pertains to the Static and Mobile Pressure Vessels Unfired Rules, 2016.
* The core objective of the amendment is to enhance safety and technical standards, specifically for pressure vessels used in hydrogen service. This can be inferred from the inclusion of specific ISO and API standards related to hydrogen compatibility and material integrity.
**4. Background and Rationale:**
This is an amendment to existing rules. The rationale for this specific amendment appears to stem from a need to address the unique challenges associated with the storage, transport, and handling of hydrogen in pressure vessels. Hydrogen embrittlement, permeation, and cryogenic valve performance necessitate stricter standards. The amendment aims to incorporate these considerations into the existing framework, likely prompted by increasing hydrogen-related activities.
**5. Key Provisions / Changes:**
The amendment introduces several key changes to the Static and Mobile Pressure Vessels Unfired Rules, 2016:
* **Rule 13(1):** Adds specific standards for pressure vessels used for hydrogen storage and transport. These include:
* ISO 17081: Measurement of hydrogen permeation and uptake in metals.
* ISO 10587: Test for residual embrittlement in metallic-coated and uncoated articles.
* ISO 16573: Measurement of hydrogen embrittlement resistance of high-strength steels.
* ISO 15330: Preloading test for hydrogen embrittlement detection in fasteners.
* The effect of this change is to mandate adherence to internationally recognized standards for assessing hydrogen compatibility. This ensures material integrity and reduces the risk of failure.
* **Rule 18:** Introduces a new sub-rule specifying that valves for cryogenic pressure vessels of hydrogen must conform to ISO 21011 or other codes acceptable to the Chief Controller.
* This change mandates specific standards for valves, ensuring their suitability for cryogenic hydrogen service.
* **Rule 19:** Introduces a new sub-rule requiring fitness-for-service assessments for hydrogen pressure vessels according to API 579, along with the relevant provisions of Rule 13 standards or other standards acceptable to the Chief Controller.
* The effect of this change is to mandate ongoing assessment of vessel integrity throughout its service life, using a recognized standard, to proactively identify and address potential issues.
* **Rule 38:** Introduces a new sub-rule that mandates pressure vessels for the transport of cryogenic hydrogen to also conform to the relevant provisions of ISO 2281 or ISO 71 or any other code as acceptable to the Chief Controller.
* **FORM LS1D:** At serial number 36, after condition 3 of the license FORM LS1D, the amendment adds "3a The premises shall ensure the safety in accordance with the provisions of EIGA 0619 and CGA P12 or any other code accepted by the Chief Controller."
* This change mandates safety standards for hydrogen handling on the premises.
**6. Target Audience and Stakeholders:**
The primary target audience and stakeholders for this amendment include:
* Manufacturers and suppliers of static and mobile pressure vessels intended for hydrogen service (storage and transport).
* Companies involved in the storage, transport, and handling of hydrogen.
* Inspection and certification bodies responsible for ensuring compliance with pressure vessel regulations.
* Chief Controller and other regulatory authorities overseeing the safety of pressure vessels.
* Premises that use hydrogen and require a license to do so.
**7. Implementation Aspects (Inferred):**
* The **Department for Promotion of Industry and Internal Trade** and the **Chief Controller** are likely the primary responsible bodies.
* The amendment comes into force on the date of its final publication in the Official Gazette.
* Pressure vessel manufacturers and operators will need to update their designs, materials, testing procedures, and operational practices to comply with the new standards.
* The Chief Controller will likely play a role in approving alternative codes and standards.
* License holders will need to ensure their premises are compliant with the standards.
**8. Expected Outcomes / Impact of Changes:**
The intended outcomes of these amendments are likely to include:
* Enhanced safety in the storage, transport, and handling of hydrogen.
* Improved reliability and longevity of pressure vessels used in hydrogen service.
* Reduced risk of incidents and accidents related to hydrogen infrastructure.
* Increased adoption of internationally recognized standards for hydrogen compatibility.
* Greater confidence in the safety of hydrogen as an energy carrier.
* Improved overall quality and safety of processes involving hydrogen.
**9. Conclusion:**
The amendment to the Static and Mobile Pressure Vessels Unfired Rules, 2016, represents a significant step towards establishing a robust regulatory framework for hydrogen infrastructure. By incorporating specific ISO and API standards, the amendment addresses critical safety considerations related to hydrogen permeation, embrittlement, cryogenic valve performance, and fitness-for-service assessments. These changes are expected to enhance the safety and reliability of pressure vessels used in hydrogen service, contributing to the broader adoption of hydrogen as a clean energy source. Affected industry should prioritize becoming familiar with and adhering to the new provisions.
