Design factors for ensuring the structural safety of fire monitors on ships

Abstract

Owing to the increasing size of modern vessels, the operating pressure of fire monitors has increased to cover larger spraying areas and distances in the event of fire, leading to more frequent occurrences of damage. This study examines the optimal design factors for preventing damage to fire monitors on ships, even under high-pressure operating conditions. This study focused on two main aspects. First, the pipe thickness is optimized to prevent damage under high-pressure conditions. Second, the force on the flange bolts that connects the pipes to the spray nozzles is evaluated, ensuring that they can withstand high pressure. The performance of these bolts plays a critical role in preventing damage. Through a systematic analysis, this study examines how these design factors affect the performance and durability of fire monitors and provides design guidelines for damage-free operations. The ultimate goal was to enhance the stability and reliability of fire monitors for effective fire suppression on ships.
