There are great differences between the design of water fire-fighting system in deep water drilling ships and that in common ships. The design and calculation is more complex due to the configuration of watering pressure stabilization system and supply of fire-fighting water for water spray system ,foam fire-fighting system and other subsystems for fire-fighting. This paper discusses the design and calculation key points of its water fire-fighting system for a deep water drilling ship with ABS classification.%深水钻井船水消防系统的设计与常规船舶有较大不同，湿式稳压系统的配置以及为水喷淋系统和泡沫消防系统等其他消防子系统提供消防水的要求，导致其设计和计算相对复杂。文中以某型入级ABS的深水钻井船为例，论述其水消防系统的设计与计算要点。
