This study aims to improve the fire safety of container ships by examining the bilge pumping performance necessary to prevent the formation of free surfaces in cargo holds when a water spray system is introduced as an active protection system on hatch covers. The study calculates whether free surfaces would occur in a cargo hold equipped with a water spray system using the bilge pumping system installed on 24,000 TEU-class container ships. The calculation results indicate that the free surface could not be prevented in all cases when only one bilge pump was operated. Even with the operation of two bilge pumps, free surfaces were still observed in all cargo holds except for the No.1 cargo hold. Design modifications, such as increasing the size of the branch bilge pipe, are necessary to prevent free surfaces in the cargo holds. Therefore, it is strongly recommended that when installing a water spray system as an active protection system on hatch covers, the bilge pumping system's ability to prevent free surfaces in the cargo holds of each individual container ship be thoroughly examined.
