本设备共 15 个失效模式（FM），其中 2 个为高风险（S≥8 或 O≥8）。 主导风险来自「同步齿轮断齿」（S=8, O=2, AP=低）。 主要失效机理：机械密封端面在润滑膜失效下发生黏着磨损, 沿轴形成泄漏通道, 齿面接触疲劳(ISO 6336 接触应力超过疲劳极限), 萌生磨损与胶合, 齿根弯曲疲劳(ISO 6336)在过载下裂纹扩展致断齿。 RCM 维修决策以 CBM 为主（CBM 14 / PM 0 / RTF 1）。 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 15 failure modes (FM), of which 2 are high-risk (S≥8 or O≥8). The dominant risk is '同步齿轮断齿' (S=8, O=2, AP=低). Main failure mechanisms: 机械密封端面在润滑膜失效下发生黏着磨损, 沿轴形成泄漏通道, 齿面接触疲劳(ISO 6336 接触应力超过疲劳极限), 萌生磨损与胶合, 齿根弯曲疲劳(ISO 6336)在过载下裂纹扩展致断齿. RCM maintenance decisions are dominated by CBM (CBM 14 / PM 0 / RTF 1). 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.

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).
