Narrative
The internal drain piping within a storage tank failed allowing crude oil to enter the piping and be released during the draining of water off the rooftop. Until the tank is taken out-of-service and cleaned, the extent and cause of the failed drain piping is unknown. The internal drain system consists of piping, flanges and the pivot master joint that consists of galvanized side plates with spiral wound gaskets and bolting hardware. The evaluation of the components of the constructed system depict that it is likely that a gasket on the system has failed. This drain piping has been isolated both ontop of the tank roof and at the valve near the shell nozzle at the bottom of the tank eliminating the possibility that crude oil can be released from it to the ground going forward. This drain system will be replaced when the tank is taken out of service for API 653 internal inspection.
