GSMR Safety Case Requirements for Anaerobic Digestion Sites

Rapid growth in anaerobic digestion means more operators may need a GSMR Safety Case. Learn what this means and how to prepare.

The rapid expansion of the anaerobic digestion sector has led many operators to encounter the need for a GSMR Safety Case for the first time. If your facility conveys gas into the gas network, your organisation may legally be considered a Gas Transporter under the Gas Safety (Management) Regulations 1996.

In these situations, a GSMR Safety Case must be submitted to the regulator to demonstrate that major accident hazards are identified and controlled.

For companies new to this regulatory framework, the process can raise a number of important questions:

  • What exactly is a Safety Case?
  • Where do regulatory responsibilities begin and end?
  • How do operators demonstrate that risks are properly managed?

When Is a GSMR Safety Case Required?

A GSMR Safety Case becomes relevant when a site transports or conveys gas as part of the public network. This is increasingly common for anaerobic digestion and biogas facilities exporting biomethane.

When a site falls within this definition, operators must demonstrate to the regulator that they have robust arrangements in place to manage safety risks associated with gas transportation.

This includes clearly identifying major accident hazards, understanding the boundaries of responsibility between network operators and site operators, and demonstrating that safety critical systems are properly managed.

Understanding the Safety Case Framework

Developing a GSMR Safety Case involves much more than producing documentation. It requires a comprehensive understanding of hazard management, safety barriers, and regulatory expectations.

Many organisations entering this regulatory space are familiar with process safety principles but may not have previously worked within a Safety Case regime. Drawing on experience from sectors such as offshore oil and gas and major hazard industries can help organisations navigate this transition effectively.

Key elements often include identifying major accident hazards, defining safety critical elements, and demonstrating how these systems are inspected, maintained, and managed throughout the lifecycle of the facility.

How OTECSA Supports GSMR Safety Case Development

At OTECSA Consulting, we support organisations across the UK anaerobic digestion sector in developing and maintaining their GSMR Safety Case. Our experience includes supporting operators who are encountering these requirements for the first time.

We are currently assisting clients with:

  • GSMR Safety Case development
  • Gap analysis and regulatory readiness
  • Major accident hazard identification
  • Safety Critical Element (SCE) definition and maintenance strategy
  • Safety Case reviews and updates

Planning Early for Compliance

If there is a possibility that your facility could fall under the Gas Safety (Management) Regulations, early preparation can make the transition significantly smoother.

Understanding the regulatory framework, defining responsibilities, and identifying hazards early allows operators to develop a robust safety case and avoid delays when engaging with the regulator.

If your organisation is navigating GSMR requirements for the first time, our team can help guide you through the process and ensure your approach aligns with regulatory expectations.
