Incident Narrative
"ON SEPTEMBER 16, 2021, A 3/16' PINHOLE DEVELOPED IN THE 6-8 LINE, ALLOWING FUEL OIL TO LEAK TO GRADE. ON SEPTEMBER 16, 2021, THE 6-8 DOT FUEL OIL LINE ALONG TERMINAL ROAD INSIDE OF PORT ARTHUR REFINERY LEAKED TO GRADE. TWO OF THE MAIN CAUSES OF THE LEAK WERE: EXTERNAL CORROSION ON THE PIPING DUE TO CORROSION UNDER INSULATION (CUI) THE PIPING WAS SUSCEPTIBLE TO EXTERNAL CORROSION BECAUSE IT WAS UNCOATED AND INSULATED. INSULATION OFTEN ALLOWS WATER INTRUSION, AND SINCE THE LINE OPERATED BELOW 212F, THE WATER STAYED IN THE INSULATION AND DID NOT EVAPORATE. THE PIPING WAS UNCOATED, SO THE MOISTURE IN THE INSULATION HAD DIRECT CONTACT WITH THE BASE METAL."
