Abstract: The procedure of bowtie analysis utilization is not clear and unified, so one of the focus is on demonstrate a clear procedure of bowtie analysis and clarify each step's content. Pig receiver system is widely used in oil, gas and process industry. And high pressure material or waste contained in pig receiver potentially threaten related personnel and equipment. To better conduct risk management for pig receiver system, a bowtie analysis is needed. Pig receiver system has three potential hazards:"high pressure gas", "flammable gas and liquid" and "pyrophoric material". Analyzing these three hazards, potential causes, consequences and barriers to formulate the bowtie diagram. By utilizing bowtie analysis, cause, consequences and barriers can be effectively analyzed and classified. The bowtie diagram could supplement other risk assessments tools' gap and provide a straightforward input for risk management.
