Abstract: An improved technology of the fire and gas detection and emergency system is presented in terms of the shortcomings of the common design for the fire and gas detection system (FGS) and the emergency shutdown (ESD) system with the requirement of the regional fire and gas shutdown by using the modular design ideas, in order to effectively enhance the reliability and safety of the Floating Production Storage and Offloading (FPSO). The emergency system can be shut down in case of accident to protect the safety of the personnel and facilities of the platform with the minimized accident losses. This scheme optimizes the range of the action of the shutdown switch with the different levels by analyzing the shutdown strategy of the emergency system based on the importance of the location of the hazard point sources. It can reduce the equipment shutdown, increase the platform output, and enhance the effectiveness and success of the emergency system in managing emergency accidents for the implementation of cost reduction and efficiency increase, while ensuring the safety of personnel and platforms.
