Narrative
On 10/5/20 at 9:20 am an enterprise technician arrived at georgetown pump station on the midland to sealy pipeline and discovered approximately 20 gallons of crude oil released from the strainer closure. Most of the crude oil was caught by a 17 gallon pan that was under the closure, and the remainder was on the concrete containment for the strainer. The strainer was isolated at the time of the incident. The lip seal in the strainer closure had become unseated due to low pressure/vacuum fluctuations during changes in line operation. The strainer was drained, and the lip seal and sealing surface were cleaned, leak tested, and placed back into service. In the short term, the lip seal continues to hold. In the long term, the manufacturer has improved the design of the lip seal to better resist low pressure/vacuum fluctuations. The improved seal has been ordered for each of the facilities with similar design.
