摘要:
油气站场一般设置有紧急停车系统（ESD）等存在操作员介入的非常规安全仪表功能（SIF），为解决已有的安全完整性等级（SIL）评估方法不能针对此类SIF进行功能安全评价的情况。对存在操作员介入的非常规SIF进行研究，将其中的人为因素细分为观察、决策和执行3个阶段；根据各类人因可靠性分析方法优缺点，筛选CREAM和HCR方法分别分析紧急情景环境和应急响应时间对非常规SIF人因失效概率的影响，建立考虑人因可靠性的SIL验证模型；基于此模型选取某输油站典型SIF开展SIL评估，分析人因失效对SIF整体可靠性的影响水平，并提出改善措施。结果表明：将操作员应急响应过程中的人因失效概率引入传统的SIL验证模型中，可实现对非常规SIF的功能安全评价；人因失效对非常规SIF具有显著影响，筛选的人因可靠性模型可准确计算人因失效概率。
Abstract:
The oil and gas stations generally have the unconventional safety instrumented functions (SIF) with the intervention from operators,e.g.,the emergency shutdown (ESD) system.In order to solve the problem that the existing evaluation methods of safety integrity level (SIL) could not conduct the functional safety evaluation on this type of SIF,the unconventional SIFs with the operator’s intervention were studied,and the human factors were subdivided into three stages,i.e.,observation,decisionmaking and execution.According to the advantages and disadvantages of various human reliability analysis methods,the cognitive reliability and error analysis method (CREAM) and the human cognitive reliability (HCR) method were selected to analyze the impact of emergency scenario environment and emergency response time on the probabilities of human failure for the unconventional SIFs,and a SIL verification model considering the human reliability was established.The SIL of a typical SIF in an oil terminal station was evaluated by using the new model proposed in the paper,then the influence level of the human failure on the overall reliability of SIF was analyzed,and the corresponding improvement measures were proposed.The results showed that the functional safety evaluation of unconventional SIFs could be realized by introducing the probability of human failure in the operator’s emergency response process into the traditional SIL verification model.The human failure played an important role in the unconventional SIF,and the selected human reliability model could accurately reflect the probabilities of human failure.
