Cause of Problem: Corrosion

During the unloading of a crude oil ship, there was a 3/4" bleeder that had become dislodged from the line during transfer. However in subsequent investigations, they found that the nipple on the crude line had failed due to internal corrosion which was the root cause of the release.

Discharge Preventable - No

Internal corrosion was not detected with visual inspection.
