Records may be supplemented or corrected and do not represent final agency causal findings.\n\nReport number: 20120022.\n\nOperator ID: 405.\n\nReported incident date: 2/8/2012 9:00.\n\nCause detail: EXTERNAL CORROSION\n\nCause detail: PLATFORM OWNER AT EUGENE ISLAND 250 CALLED TO INFORM US THAT WE HAD A BONNET LEAKING ON A CHECK VALVE ON THE VENT SYSTEM. WHEN PIPELINE TECHS ARRIVED ON THE PLATFORM TO INVESTIGATE, THEY FOUND IT WASN'T ON THE BONNET OF THE CHECK VALVE. THERE IS A LOW PRESSURE LEAK ON A 4\" VENT PIPE JUST BEFORE IT CONNECTS TO THE PRODUCERS VENT SYSTEM. IT IS AN ATMOSPHERIC CORROSION LEAK WHERE THE PIPE IS SITTING ON AN ANGLE IRON BRACE. THE VENT SYSTEM IS OPEN TO ATMOSPHERE BUT THERE IS ENOUGH LEAKING GAS IN THE SYSTEM TO DETECT THE LEAK. SUBSEQUENTLY, THE LEAK WAS REPAIRED BY REMOVING THE LINE, IN NOVEMBER, 2012.\n\nPHMSA trend classification: not significant, not serious.\n\nPHMSA standardized cause: CORROSION — EXTERNAL.\n\nPHMSA indexed costs: $89,000 reported total cost, $48,109.881 in 1984 dollars, $114,354.98 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data. They do not represent final agency causal findings.","truncated":false,"body_characters":1494}
