Narrative
During a station checkout due to a callout, p66 pipeliner discovered the air conditioner in the control building at cr-02 westlake meter station had failed resulting in plc equipment fault due to the high temperature environment. In coordination with p66 technician and control center, the pipeliner initiated a station reset. The plc reset resulted in the meter backpressure control valve to close and subsequent hi/hi discharge pressure shutdown at the origination station. The meter station pressure did not exceed mop, however subsequent investigation found evidence of damage due to over-torqueing of the non-metallic paper flange gasket. Actions taken to prevent re-occurrence: 1. A temperature monitor with hi temp level alarm to control center was added to the meter station building to provide early warning of possible air conditioner failure that could have adverse effect on control equipment. 2. Phillips 66 pipeliners were re-qualified on oq for proper torqueing procedures. 3. The local workgroup conducted re-training on procedures for proper torqueing of flanged pipe joints and proper gasket selection 4. The failed gasket was replaced with the company preferred spiral wound metallic gasket and properly torqued by qualified individuals. 5. The similar origination station strainer gasket was replaced verified to be properly torqued (no evidence of over-torqueing found) 6. Control center modified operating procedures to shut down the pipeline system in the event of a plc communication failure.
