Narrative
On 5/27/2017 the control room received a hydrocarbon alarm via the hmi. The control room immediately shut down and sent an operator to pit 4 to confirm if gasoline leak had occurred. Upon confirmation, the assets were stripped of product and the gasket was determined to have failed on a flange due to thermal pressure. Upon further investigation, thermal overpressure was discounted since the pressure charts did not show the pressure exceeding mop. The cause of the release can be attributed to a few compounding factors. We believe the section in question was under mechanical stress, from contraction and expansion from fluctuating temperatures (seasonal changes), which along with some bolt surface corrosion caused the flange to splay open and the gasket to fail. The gasket and bolts were replaced. To mitigate the mechanical stress in the area the entire related header in pit 4 was replaced.
