What happened

Gas leaking from the 36-inch pipeline receipt area at ONGC's Hazira gas-processing plant formed a vapor cloud and ignited, producing several blast-like reports and a major fire. ONGC activated the emergency shutdown, isolated gas supplies and depressurized plant piping through the flare system. The fire was extinguished by about 07:30, with no injuries or casualties. The shutdown disrupted the northwestern gas network: GAIL imposed allocation cuts of up to 40%, NTPC temporarily shut its Kawas and Jhanor-Gandhar gas-fired power stations, and fertilizer production was reduced. Government production reporting later cited closure of western-offshore gas wells during the Hazira shutdown and subsequent normalization as a contributor to September's output shortfall.
