Narrative
On 10/23/2016 at approximately 21:51 the s1 pipeline lost suction pressure. The on-duty controller immediately shutdown the mainline pumps and dispatched technicians to the pump stations downstream to investigate. At approximately 23:25 it was confirmed that the s1 pipeline had ruptured and the nrc call was immediately placed. The affected segment was isolated by closing the mainline valve at milepost 13. The affected joint of pipe was cut out and replaced, the line re-inventoried, and placed back into service. This report will be updated at a later time to include the results from metallurgical analysis. Update: 2-17-17 the failure occurred at a damaged location (shallow gouge) in the pipe, which created a local stress riser. A fatigue crack was initiated at the bottom of shear cracks formed at the time the gouge damage occurred.
