Work Description & Methodology

This project showcased SNG’s large-bore engineering capability. The methodology included deep structural piling to support the pipeline weight in variable soil conditions. Specialized welding and NDT testing were used to ensure the integrity of every joint. The project concluded with a complex connection to the live water main, followed by full disinfection and pressure testing to meet utility provider standards.

Current Status

Completed

Handed over with finalized welding logs, NDT results, and pressure test certifications.
