Main Line Valves (MLV)
MLV are provided at every km for isolation of pipeline during emergency & repairs.
These are locally as well as remotely operated type
Compressor Stations
Compressor Stations (CS) placed at km intervals to maintain desired pressure in pipeline.
Aero derivative machines with 93+ MW capacity at each CS
SCADA System
Provided for monitoring and control of pipeline operations.
Leak Detection System
It extends the functionality to perform leak detection, leak location, pig tracking, predictive modeling, look ahead modeling and operator Training

5. EWPL EIA, HAZID, QRA and HAZOP Studies
Environment Impact Assessment Study
Hazardous Scenarios Identified for Pipeline QRA Study:
- Hole/crack of approximate 20% aperture area of pipeline dia.
- Rupture having area equal to pipeline dia.(100% aperture area)
Worst Case Scenarios
- Rupture / crack having an area equal to pipeline dia.
- High Consequence Areas
- Rupture of compressor station suction loop pipeline
- Rupture of compressor station discharge loop pipeline
Risk Assessment Study
- Results were in Broadly Acceptable Region of IRPA
Seismic Study & HAZOP Study
