Narrative
While proving a meter at the south central terminal (near foster oklahoma), a crimp fitting on a "tank truck corrugated 500 psi" hose failed allowing crude to spill. A 3rd party mobile proving truck was being used to perform the testing utilizing rubber hoses to connect the proving truck to the enable meter while an enable representative onsite as a witness. After connecting the rubber hoses, the enable o&m technician provided an alert of proving and reduced the operating pressure to 350 psig to initiate the testing. Shortly after doing so, the hose separated from the fitting at the meter allowing crude oil to spill. The area was immediately isolated and approximately 35 bbls of crude was released. All released liquids stayed on location with 15 bbls in containment and 20 bbls to the ground surface. The 3rd party contractor took the failed hose to the manufacturer (midwest hose, oklahoma city, ok) who could not determine the cause of the failure. The hose did not have documented inspections, only visual inspections of the hose were performed prior to each use. Normal operating pressures for proving are around 350 psi and the hose was rated for 500 psi. An initial call was provided to the nrc (nrc #1255936) on 8/21/19 at 14:58. A 48 hour follow up call was provided to the nrc (nrc #1256127) on 8/23/19 08:01. 3/6/2020 supplemental b.5 garvin was changed to stephens
