OSBRA is the 964 Km pipeline which supplies over 6.000.000 m3/year of gasoline, diesel oil and LPG to Brazil Mid-West region. Products on OSBRA pipeline are pumped on 24 hours a day and 365 days a year scheduled basis from Planalto Paulista Refinary – REPLAN to 5 midsize cities through 6 remote operated pumping stations located along the pipeline. OSBRA pipeline operation including pumping, valve operation and tank farm monitoring are done remotely from PETROBRAS Transporte S/A – TRANSPETRO Pipeline Control Center - CCO. A real time leak detection system (LDS) was supplied and installed at this Pipeline Control Center. The LDS is based on measurements of flow, pressure and density as well as pump and valve status along the pipeline. A SCADA was implemented and field instrumentation measurements were observed in order to provide good quality data for the pipeline operation and its LDS. Assembling of some field instruments were improved in order to correct measurement fails. On-desk simulations were done in order to verify theoretical system performance and operation team was trained to use the leak detection tool. A field controlled leak simulation test was done in order to validate and verify the System performance. This apparently simple task demanded around 1 year for planning and implementation before test was done. The approach of this report is mainly operational and shows how the OSBRA LDS test was planned, programmed, commissioned and performed. Coordination and integration of Operation, Maintenance, Pipeline, Engineering, Safety, Telecommunication and Logistic teams are demonstrated in order to get good results. Field activities like designing and assembling of spools and instrumentations necessary to execute a controlled pipeline liquid hydrocarbon take off are showed. Safety and environmental precautions to avoid equipment damage, uncontrolled operation or product leak to environment are demonstrated.
