Narrative
At approximately 08:21 on october 16th, 2017, oneok pipeline control received a call from the oneok contract inspector working with the nde team at the oneok blue river pump station. The inspector had identified and an ice ball and vapors coming from a weld-o-let for the 1" flare line on the discharge piping of the pump. The pump suction valve and discharge valve had previously been closed which isolated the failure. Operations personnel responded to the site and locked-out the pump piping and de-pressured the piping. This piping had been previously excavated and the coating removed to allow for a nde examination. The exposed 1" flare piping connected to the weld-o-let had been left unsupported which allowed the weld-o-let to fail. The discharge piping with the cracked weld-o-let was removed and replaced with new pre-tested pipe with a nipple-o-let installed. The pump station has been isolated from the pipeline and hydrocarbons evacuated until all nde testing is complete. Edited 5/17/2018 by n. Jones the pump station was returned to service on 3/01/2017 at 17:00 hrs. Following the completion of the nde testing and additional maintenance.
