Narrative
On 10/22/18, port hudson operator was performing daily patrol of the facility when he noticed stream of crude oil coming out of the tank mixer for tank 34200 and collecting within the containment area at 7:36am. The operator immediately contacted supervision at 7:38am. Local operations begin to transfer product out of tank 34200 to reduce the level below the mixer. Mechanic arrived at approximately 8:00am and engaged the tank mixer shutoff to stop the product from leaking. Local operations begin to deploy boom and spill pads around perimeter of product volume to help contain while the spill response contractor arrived which was at approximately 10:30am. Oil response crews begin recovering product using vac trucks. All product has been recovered and the site has been restored to original state. Genesis is currently in discussion with mixer and seal manufacturers to discover the cause of the failure. Note: part e, question 1 is the approximate head pressure on the tank mixer based on the height of the product level. Part e, question 2 is the mop for the incoming 24" pipeline. Part e, question 5f had to be answered so it was applied to the incoming 24" pipeline. Note: the following questions had to be answered due to the submittal deadline. Due to the nature of the electronic submittal, the questions had to be answered or the system would not allow the report to be submitted. These questions will be corrected on the supplemental report. Part d, question 8 - costs have not been collected yet. Part e, question 6, 7, and 9 - data has not been collected yet supplemental (5/06/19) - part d and e have been updated to reflect the most current information. Part g was properly filled in according to an incident analysis performed by a genesis committee. Internal investigation results: an internal investigation discovered that the cause of the release was the wear and tear of some of the internal parts of the of the mixer related to the mechanical seal. A tension spring designed to hold the seal with the proper force seemed to have failed just enough to impair the seal integrity. At the time of the release, the mixer had been operating for approximately 4 years - within the recommended life expectancy of the mechanical seal. At the conclusion of the investigation, it could not be determined if the parts failed due to design oversight, material fatigue, equipment damage caused by operating conditions, or product working life. As a result of the investigation, genesis has replaced the same model seals at this and other facilities with an improved version from the manufacturer as well as made other improvements recommended by the manufacturer.
