Summary
BSEE investigates heater treater overheating at Castex’s Vermilion 252-A platform on 9–10 September 2019. The report examines burner adjustment, restricted exhaust flow, ineffective temperature shutdowns, inadequate thermowell installation and delayed shut-in. It records equipment damage, inspection deficiencies and subsequent liquid-level corrections, while retaining uncertainty over several contributing mechanisms.
