Abstract：Inert gas system can provide safe and stable oil storage environment for the cargo oil tank of floating production, storage and offloading unit (FPSO). The localization of inert gas equipment has great significance for breaking the overseas technical monopoly and reduce oilfield development investment.We introduce the structural design, numerical simulation and key technologies of dual-fuel inert gas generator localization and list the successful practice of the equipment prototype, which was jointly developed by CNOOC and equipment manufacturer. The manufacturing of this prototype is a big promotion for the localization of inert gas generator.
