Investigation Status
No, the operator did not find that an investigation of the controller(s) actions or control room issues was necessary due to: (provide an explanation for why the operator did not investigate)
Investigation Status Details
After trending the pipeline pressures it was determined that an over-pressure did not occur. Due to the small volume and the location of the leak the controller would not have reasonably been expected to see the leak. The controller did an excellent job getting things shut in/shutdown and working with field personnel.
