“ GIS Based Emergency Response Support System for EWPL Emergencies” 28th Feb’2011

East West Gas Pipeline Highlights Longest 1375 km length, natural gas cross country pipeline traversing through 630+ Villages in Four States Largest Diameter, 48 inch, Pipeline Highest Capacity, 80 MMSCMD, Highest Operating Pressure, 98 bar g, Total 27 Aero Derivative & 5 Industrial Machines with Total 900+ MW. 100% Remote Operation from Mumbai Pipeline Operation Centre (POC) with Standby POC at Gadimoga in AP Unique Emergency Response Support System

EWPL System

EWPL Facilities Design & Construction Main Line Valves (MLV) MLV are provided at every 35-40 km for isolation of pipeline during emergency & repairs. These are locally as well as remotely operated type Compressor Stations Compressor Stations (CS) placed at 130-160 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

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
