Abstract: Floating production storage and offloading (FPSO) unit is an offshore oil and gas processing unit that integrates the ship hull system, topside oil and gas processing system, mooring system and export system. The system of FPSO is very complex and easy to cause serious accidents in case of oil and gas leakage. The firefighting system is the important subsystem of FPSO ship system and the important guarantee for personnel and production. The fire situation in the fire compartment has been analyzed to configure the reasonable extinguishing methods aiming at the rationality of the firefighting system design and the equipment selection for the internal turret moored FPSO. A calculation method for the firefighting system of the internal turret FPSO is then proposed based on the relevant rules and regulations. It can improve the safety and reliability of the firefighting system design and ensure the safety of the FPSO production and the crew safety. This firefighting system calculation method is critical to the design of the firefighting system and the equipment selection. It can provide reference for the design of the FPSO firefighting system.

摘要： FPSO是集船体的船舶系统、上部模块油气处理系统、系泊系统和外输系统于一体的海上油气处理装置,其系统较复杂,油气泄漏时极易引发严重事故。消防系统是FPSO船舶系统的重要子系统,是人员和生产的重要保障。文中针对内转塔式FPSO消防系统设计及设备选型的合理性问题,分析防火分区发生火灾情况,配置合理的灭火方式,结合相关规范规则,提出了一种内转塔式FPSO消防系统计算方法,可以提高消防系统设计的安全可靠性,保证FPSO安全生产及人员生命安全。该消防系统计算方法对消防系统设计及设备选型起到了关键作用,对FPSO消防系统设计有一定借鉴意义。
