To address issues such as the incomplete technical standard system and inconsistent configuration parameters of fire protection facilities in the design of fire protection systems for liquefied petroleum gas(LPG)terminals, this study combines practical engineering cases by reviewing domestic and international codes and standards.Through numerical calculations, comparative analysis, quantitative models, and other methods, it focuses on breakthroughs in key technologies including the optimization of design flow rates for fire-cooling water monitors, selection of integrated control methods for fire protection facilities, and adaptability of monitor tower heights.The research clarifies multivariate relationships between the design flow rate, range, coverage area, and wind direction of cooling water monitors.It proposes fire scenario-based control strategies for fire protection facilities and establishes a dynamic quantitative model between the monitor tower height and the draft depth of unloaded ship types.The research results provide theoretical basis for the standardized design of fire protection systems for LPG terminals, effectively resolve long-standing design differences in the industry, and have engineering practical value for enhancing the fire safety of hazardous chemical terminals.
