Narrative
Following a localized power outage resulting in the loss of scada communications and the subsequent closure of downstream outlets (terminal tankage and downstream pipelines), the manual operation of a flowback pump allowed the system to overpressure resulting in the failure of a insulating kit on a pipeline flange. The closure of downstream outlets, automated shutdown of all system pumps and handover of control to local operations is normal operating procedure for all control room personnel during power outages resulting in loss of scada communications. In this situation, a contractor working for wpx energy upstream of stateline crude, llc overrode the automatic shutdown of a pump during flowback operations which resulted in the over-pressurization when downstream outlets were closed. This contractor was not doing work for stateline crude, llc and was not hired by stateline crude, llc. The failure investigation found that stateline crude, llc had inadequate procedures regarding producers having access to its plc's. Stateline crude, llc has changed the procedures so now only company personnel have access to overpressure shutdowns on pumps.
