Incident Narrative

MONDAY (03/02/2015) AT APPROXIMATELY 9:15 AM A P66 CONTRACTOR OBSERVED AN NGL LEAK ON A MX-20 MAINLINE PIPE FLANGE. THE PIPELINE WAS SHUT DOWN AND A SECTION OF THE LINE WAS DE-PRESSURED TO ALLOW THE FLANGE GASKET (WHICH HAD LEAKED) TO BE REPLACED. WHEN THE FAILED GASKET WAS PULLED FROM THE PIPE IT WAS FOUND THAT SEVERAL ROUNDS OF THE SPIRAL WOUND GASKET WERE MISSING. MOST LIKELY CAUSE IS A SIZING TOOL HAD BEEN RUN IN THE LINE TWO DAYS PRIOR TO THE LEAK. THIS TOOL LIKELY CAUGHT THE SPIRAL WOUND GASKET AND UNWOUND SOME OF THE GASKET WINDINGS, THUS WEAKENING THE GASKET. A NEW GASKET WAS INSTALLED WITH A REINFORCED INNER RING WHICH PREVENTS THAT FROM HAPPENING IN THE FUTURE. THE LINE WAS REPRESSURED AND RE-STARTED AT APPROXIMATELY 15:00 HRS ON 3/3/2015.
