Incident Narrative
"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."
