At the heart of India’s cleaner energy movement is the rapid expansion of (CGD) networks. These systems provide piped natural gas (PNG) to households and industries, and compressed natural gas (CNG) for vehicles—reducing our dependence on polluting fuels. But building this infrastructure across dense, challenging terrains takes more than engineering—it takes vision, precision, and regulatory expertise.
This case study highlights how Oceanic Infra Private Limited, a leading infrastructure contractor, successfully delivered complex CGD projects across key regions, helping gas utility companies fulfill their rollout commitments on time and with uncompromising safety standards.
Project 1: City Gas Distribution Pipeline in Nagpur, Maharashtra
Client: Authorized CGD Operator
Scope: Laying of 60+ km of Medium-Density Polyethylene (MDPE) and carbon steel pipelines across residential and commercial zones.
Duration: 8 months
Status: Completed ahead of schedule
Key Challenges:
- Urban congestion with heavy underground utility presence
- Traffic management during pipe-laying
- Rainy season interruptions
- Public safety concerns
Oceanic Infra’s Solutions:
- Deployed Horizontal Directional Drilling (HDD) to minimize road cutting
- Coordinated with municipal authorities for nighttime execution
- Used GIS-based mapping for underground asset visibility
- Conducted safety awareness sessions for residents
Result:
- Zero-accident execution
- Achieved all safety and quality audit clearances
- Commended by client for early delivery and minimal public disruption
Project 2: Steel Pipeline Trunk Line for Industrial CGD, Gujarat
Client: Large CGD Licensee (Industrial & Commercial focus)
Scope: Installation of 12 km high-pressure steel pipeline for an industrial zone
Pressure Class: > 19 bar
Duration: 5 months
Terrain: Semi-urban + rocky zones
Key Challenges:
- Terrain included rocky subsoil requiring controlled blasting
- Routing through a protected environmental zone
- Complex welding and testing requirements
Oceanic Infra’s Solutions:
- Used hydraulic trenching and rock-cutting equipment
- Obtained environmental clearance and forest permissions
- Deployed a team of ASME-certified welders
- Carried out hydrotesting and radiographic weld inspections
Result:
- Seamless commissioning without leakage or defects
- Fully PNGRB-compliant documentation
- Client signed a multi-year extension for additional zones
📍 Project 3: CNG Station Pipeline Connectivity – Southern India
Client: New entrant CGD operator
Scope: Connecting 5 CNG stations across a 25-km radius to the main gas pipeline
Timeline: Tight deadline of 3 months for Go-Live
Location: Tier-2 city with narrow urban roadways
Key Challenges:
- Road width restrictions limiting equipment access
- Multiple agency clearances required within a short time
- Local community resistance due to lack of awareness
Oceanic Infra’s Solutions:
- Deployed compact trenching machines for narrow access
- Engaged a dedicated approvals & liaison team
- Organized community meetings and handouts on gas safety and benefits
- Maintained 24×7 on-site supervision to avoid delays
Result:
- Go-Live achieved 5 days ahead of deadline
- High operational uptime post-commissioning
- Helped unlock fuel access for over 3,000+ CNG vehicles
