Narrative
The booster pump upstream of the valve was started, and pressure was rising at the suction of mainline unit one. The suction valve was opening correctly, after the suction valve had reached 50% open and an o-ring and gasket failed on the suction valve. Thus releasing a spray of crude oil. Investigation found inadequate thermal relief that led to the valve failure. A thermal relief was provided but set at an incorrect pressure. It was set to relieve at a pressure higher than the established mop of the adjacent piping. The valve was removed, inspected and rebuilt and hydro-tested. A thorough review was conducted to verify adequate thermal relief and to ensure adequate overpressure protection for the entire station.
