GENESIS PIPELINE USA, L.P.

Incident Narrative

GENESIS RECEIVED A CALL FROM A NEIGHBORING PIPELINE OPERATOR THAT THEIR AERIAL PATROL SPOTTED OIL ON THE GROUND NEAR THE GENESIS ROW SOUTH OF BROOKHAVEN, MS. THE PIPELINE WAS SHUT DOWN AND PERSONNEL WERE DISPATCHED TO LOCATION AND ARRIVED TO FIND PRODUCT SPRAYING FROM A VALVE. OSRO CALLED FOR CLEAN-UP. INSPECTION OF THE VALVE SHOWED THAT IT WAS A REFURBISHED VALVE THAT WAS NOT INSTALLED PROPERLY BY THE CONTRACTOR IN 2006. IT WAS DISCOVERED THAT THE VALVE BONNET FLANGE DID NOT HAVE A O-RING IN THE O-RING GROOVE. IN ITS PLACE, THE CONTRACTOR HAD USED A SILICONE SEALANT INSTEAD OF USING THE MANUFACTURER'S RECOMMENDED PARTS. THE SILICONE USED HAD BECOME BRITTLE AND CRACKED OVER TIME CAUSING THE BONNET FLANGE TO LEAK. THE VALVE WAS REPAIRED AND THE PIPELINE WAS PLACED BACK INTO SERVICE.
