Narrative
On may 20, 2014 a release of petroleum product was reported to explorer pipeline from a remote operated block valve (robv) at mile post 8.98 outside of port arthur, texas on the 28 inch system. The source of the release was from a pressure transmitter mounted on the upstream side of the robv. An investigation into the transmitter identified the source as a transmitter adapter o-ring that had partially protruded through the adapter. A transmitter adapter bolt was found to have backed out enough to allow the o-ring to protrude through the adapter resulting in the release. The investigation could not verify that a transmitter adapter bolt was torqued to the required torque value.
