Help & Support

The Challenges Subterra Faced:

Risk of Accident: The proximity of the damaged pipeline to the train line heightened the risk of a potential gas leak, necessitating a swift resolution.

Major Disruption: The incident led to the suspension of train services, requiring immediate deployment of rail replacement buses and evacuation of nearby facilities.

Access Difficulties: The damaged pipeline traversed multiple properties and railway infrastructure, posing challenges for repair works within a tight timeframe.

Potential Impact: As a critical gas supply line, shutting off the gas flow for repairs would have affected numerous properties, requiring extensive safety checks upon restoration.

The Radius Subterra Solution:

Emergency Response: The gas network owner promptly engaged Radius Subterra, a specialist pipeline engineering company known for its immense technical expertise spanning decades and bespoke solutions.

Collaborative Approach: Radius Subterra collaborated with the gas network owner to devise an innovative solution that ensured continuous gas flow while addressing the damage.

Unique Solution: Radius Subterra installed a Minimuss 150mm outlet branch saddle on the damaged 268mm pipeline, creating a bypass to maintain gas flow safely. This allowed the gas to continue flowing while repairs were underway.

Damage Encapsulation: To permanently fix the leak, Radius Subterra fitted a Minimuss 250mm branch saddle over the damaged section, securing the pipeline and preventing further leakage. This was completed by blanking the outlet off, ensuring a safe and permanent solution.

Benefits
