Narrative
An isolated segment of tank line that had a temporary skillet installed on the upstream side of the tank valve. This segment on tank line was thermally pressured without relief and deformed the temporary skillet which led the gasket to fail at the 12 o'clock position releasing crude oil. The tank line segment was drained, skillet removed, replaced with new gaskets and tank line segment provided thermal relief path for this segment of pipe. Operations did not recognize a thermal relief had been open to the isolated segment of pipe with the skillet blind. Estimated approx. 30 to 100 psi to deform the skillet.
