This paper presents an advanced system for repairing pipe leakages in oil and gas pipelines, with a case study on water supply lines, using epoxy aramid fibre plugs and carbon-glass hybrid FRP plates. The system is designed for field application under complex & challenging conditions, where traditional welding or extensive surface preparation is not feasible. The epoxy impregnated aramid fibre plug hardens quickly and can be applied directly to leakage points with minimal surface drying or preparation. This plug provides a durable and flexible seal, akin to the principle of puncture repair system for automobile tires. To further reinforce the repair, carbon-glass hybrid plates, sized between 100 × 100 to 500 × 500 mm, are contoured to match the pipe’s curvature and affixed using high-viscosity epoxy adhesive. This double-layered protection improves the system’s ability to withstand operational stresses, making it an ideal replacement for welding techniques, especially in locations where welding is impractical due to environmental or safety concerns. The study highlights further research areas to provide life prediction models. This will help assess the long-term viability of the repaired areas under dynamic pipeline conditions and help improve the mechanical performance and interfacial bonding of the epoxy aramid plugs and hybrid plates. Additionally, the benefits of this method are presented with the help of a case study of a repair site to emphasise on the benefits of the system’s potential as a reliable, cost-effective, and non-invasive method for pipeline maintenance and leakage prevention.
