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
