| 摘 要： | 火气系统属于减缓层内的安全仪表系统,在减轻事故后果方面起到非常重要的作用。针对传统火气系统只满足功能需求设计的不足,提出与风险分析相结合的火气系统设计新理念,以具体案例分析场景危险性,通过覆盖率、可用性、有效性等参数,定量场景的潜在生命损失,以风险降低为目的,量化计算事故后果和频率,评估火气系统的有效性。

| Abstract: | Fire & Gas system, as a mitigation layer of safety instrument system, is important to mitigate the outcome of hazard. This paper combines risk concept with F&G system to quantify the frequency and consequences of accident and assess the effectiveness of F&G system. Case studies of specific risk scenarios are conducted, in which factors of coverage, availability and effectiveness are used for analysis. |
