Incident Narrative
"ON FEBRUARY 23RD, 2020 AT APPROXIMATELY 0500, FLOW RATE WAS INCREASED FROM THE CRANE II BREAKOUT STATION VIA MIDLAND TO CRANE 24' PIPELINE TO OUR MIDLAND BREAKOUT STATION. DURING THE INCREASE OF FLOW, THE BACK-PRESSURE CONTROL VALVES BEGAN TO CLOSE ON THE INLET METER SKID. THE LOGIC IN THE CONTROL SYSTEM IS SET BY PRESSURE AND THEN SWITCHES OVER TO FLOW AFTER 6,000 BPH. THE BACK-PRESSURE VALVES BEGAN TO CLOSE PRESSURING UP THE INLET METER SKID. THIS CAUSED THE METER RELIEF VALVES TO LIFT FILLING SUMP CONTAINMENT. THE SUMP PUMP COULD NOT KEEP UP WITH THE AMOUNT OF VOLUME FROM THE RELIEF VALVES CAUSING A SMALL BREECH OF THE PRIMARY CONTAINMENT. THE ROOT CAUSE WAS THE FLOW SET POINT WAS EXCEEDED. ORYX MIDSTREAM HAS CORRECTED THE LOGIC ISSUE TO ENSURE THAT FLOW CONTROL CANNOT TAKE OVER THE PRIMARY PRESSURE COMMAND."
