Abstract: To address the problem of imbalanced wind pressure and high temperature in various compartments of FPSO,information integration technology is used to collect real-time ventilation air volume,wind speed,wind resistance,and temperature parameters of each compartment of FPSO. The signals of existing thermal,fire and gas sensors are connected to establish the compartment and ventilation network models,so as to visually view the variation of the ventilation network and compartment parameters. The intelligent decision-making software is used to regulate the compartment air dampers and fans. In case of danger,risk warning prompts are issued to assist command personnel in escape and rescue.

Key words: intelligent control, 3D modeling, wind network calculation, ventilation system
