本设备共 16 个失效模式(FM),其中 4 个为高风险(S≥8 或 O≥8)。 主导风险来自「拒动(SIS 该动不动)」(S=9, O=2, AP=中)。 主要失效机理:内部腐蚀(冷凝水), 外部腐蚀/CUI, 干燥剂失效。 RCM 维修决策以 PM 为主(CBM 3 / PM 13 / RTF 0)。 建议优先对高风险 FM 安排 RBI 定点测厚与在线监测复核;含合金部件须执行 PMI 抽检;缺陷按 API 579-1 FFS 闭环。This equipment has 16 failure modes (FM), of which 4 are high-risk (S≥8 or O≥8). The dominant risk is '拒动(SIS 该动不动)' (S=9, O=2, AP=中). Main failure mechanisms: 内部腐蚀(冷凝水), 外部腐蚀/CUI, 干燥剂失效. RCM maintenance decisions are dominated by PM (CBM 3 / PM 13 / RTF 0). Recommendation: prioritize RBI spot thickness measurement and online-monitoring review for high-risk FMs; perform PMI sampling on alloy components; close defects per API 579-1 FFS.

4.1 处方与成本权衡4.1 Prescription & Cost Trade-off

成本取自 crq 参数(cp=检验成本,cf=失效纠正成本),预期风险削减为不执行该工单的年度失效概率上限近似。当前 crq 未标实测来源,统一标注 prior-template(非装置实测成本);实测数据经 ingest_measured 审批并入后转 posterior,削减值将升级为风险成本率精算(goal_planning._cost_rate_at)。Costs are drawn from crq parameters (cp = inspection cost, cf = failure correction cost); expected risk reduction approximates the upper bound of annual failure probability if the work order is not executed. Current crq has no measured source, uniformly tagged prior-template (not as-found plant cost); once measured data is approved and ingested via ingest_measured it switches to posterior, and the reduction upgrades to a risk-cost-rate actuarial value (goal_planning._cost_rate_at).
