Deadly Blast Hits Major Indian Refinery as Fuel Markets Tighten
A powerful explosion and fire damaged a unit at Mangalore Refinery and Petrochemicals Ltd. (MRPL) on Wednesday, killing one worker and injuring at least eight others. The blast occurred in the Coker Hydrotreater Unit when a high-pressure Cold Separator ruptured; the company isolated the affected unit and extinguished the fire after roughly two and a half hours.
Why It Matters
The incident comes as India’s refiners are running plants above normal rates to counter tight diesel supplies and disruptions to Middle Eastern crude flows, so any prolonged outage at MRPL’s 15-million-tonne-per-year facility could further tighten domestic and export fuel markets. How long the hydrotreater will be offline — and whether overall throughput is affected — remains unclear.
Key Facts
- Casualties: 1 worker killed, at least 8 injured
- Unit affected: High-pressure Cold Separator in the Coker Hydrotreater Unit
- Refinery: Mangalore Refinery and Petrochemicals Ltd. (MRPL), 15 million tonnes per year capacity
- Time of incident: Around noon local time on Wednesday
- Fire duration: About two and a half hours to extinguish
A major explosion and subsequent fire struck MRPL’s Mangaluru refinery on Wednesday when a high-pressure Cold Separator ruptured in the Coker Hydrotreater Unit, company statements and local authorities said. Emergency and firefighting teams from MRPL responded and the company reported the affected unit had been isolated; officials had not disclosed the extent of damage or an expected repair timeline.
The blast was strong enough to be heard more than 10 kilometers away, and local accounts described broken windows and damage to nearby buildings. MRPL confirmed one worker died and at least eight others were injured in the incident. The fire took roughly two and a half hours to bring under control.
MRPL operates a 15-million-tonne-per-year complex on India’s southwest coast and produces diesel, gasoline, jet fuel and other products for domestic and export markets. The Coker Hydrotreater Unit is part of the refinery’s Phase 3 complex and processes outputs from coking operations to remove sulfur and other contaminants; the company has not specified how long the unit will be offline or whether overall refinery throughput will be reduced.
The timing of the accident coincides with refiners across India running plants above normal rates to offset tight diesel supplies and high refining margins after disruptions to Middle Eastern energy flows. MRPL had planned to operate the Mangaluru refinery above 100% of capacity through March 2027, and the company earlier in 2026 declared force majeure on gasoline exports amid crude supply disruptions linked to the Iran conflict. Market effects will depend on MRPL’s ability to sustain runs while the damaged hydrotreater is inspected and repaired.
