During trunkline pigging operations being carried out in a Middle East oilfield, a pressure build-up was being generated in the flare header of its central processing facilities (CPF). Due to the limit settings in the high-integrity pressure protection system (HIPPS), the pressure build-up risked a production trip. The operator employed Inprocess to analyse, through the use of dynamic simulation, if there were operational or process control alternatives that would allow the execution of current pigging operations to continue without production trips.
