“ GIS Based Emergency Response Support Systemof RGTIL – EWPL ” 19-Sep-14
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
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
RGTIL EWPL Major HSE Challenges & Concerns / Risk • Multi site operations from Pipeline Operations Centre located at Navi Mumbai or Gadimoga • Large volume of high pressure flammable gas transportation • High consequences even with very low frequency incidents • Emergency services (Fire/Police/Hospitals etc.) not in near vicinity • Un-authorized third party activities on pipeline Right of Use. • Safe conductance of patrolling/surveillance involving long journey • Avoidance and combating poisonous reptile attacks while patrolling pipeline facilities in agricultural fields/jungles • Coordination with Govt./statutory authorities for participation in on-site emergency mock drills
EWPL ERDM Preparedness • Categorization of Emergencies • Emergency Organization • Emergency Notification Matrix • Emergency Response Vehicle • First Responders Kit • Liaison with Local Fire Services, Hospitals, Police etc • Reliance Mitra across pipeline corridor • Emergency Drills Training and Rehearsal • Emergency Response Support System (ERSS)
