Narrative
Approximately 2.9 barrels of crude oil was released due to crevice corrosion between an angle iron stairway support attachment weld and the tank shell. Water and condensation had become trapped between the angle iron stairway support and tank shell, causing the coating to deteriorate and crevice corrosion to form at the attachment weld and shell. Porosity trapped in the weld and burn through may also have contributed to the pinhole leak. The pinhole leak was located on the .250" thick carbon steel plate of the top shell course. The affected area was not in a vertical or circumferential weld seam.
