Summary
An offshore production alert describes a two-barrel oil spill after a fluid surge and downstream orifice restriction overpressurised a chem-electric heater treater. Its rupture disc failed before high-pressure shutdown activated. The operator subsequently disabled the disc outlet and resized two pressure safety valves to accommodate maximum emergency liquid discharge rates.
