Narrative
During normal butane delivery operations, a valve closed inside the total refinery. At the time, the pipeline was flowing through the prover loop. The pressure in the prover loop increased when total's valve closed. The pressure did not exceed the mop of the piping - the line operates at approximately half of its mop during normal operations. The pressure increase caused a gasket on the prover loop to fail. The prover loop was isolated and blown down, and all gaskets on the prover loop were replaced with gaskets of a more reliable design. The line was shut down until the prover had been blown down and it was safe for personnel to enter the area, at which time the prover was bypassed and normal deliveries to the total refinery resumed.
