The Mangalore Refinery, operated by MRPL (a subsidiary of ONGC) near Katipalla on India's southwest coast, is a 15.0 MMTPA integrated refinery and petrochemical complex with a Nelson Complexity Index of 11.3 — one of the highest among Indian public sector refineries.

Commissioned in 1988 at 3.69 MMTPA and expanded through three successive phases, the refinery is distinguished by its unique configuration featuring two hydrocrackers producing premium low-sulphur diesel and Aviation Turbine Fuel, two CCR units delivering high-octane unleaded petrol, and a Petrochemical FCC Unit (PFCCU) feeding a 440,000 TPA polypropylene plant — making it the only Indian Public Sector Undertaking (PSU) refinery to combine these capabilities.

Crude oil is received directly via a Single Point Mooring (SPM) buoy and two captive jetties at New Mangalore Port, enabling VLCC-scale imports across a wide 24–46° API crude gravity range, while finished products are exported to Asian, European, and Middle Eastern markets — the refinery having set an all-time Indian PSU throughput record of 17.14 MMTPA in FY2023–24.
