Risk-Based Inspection

6.6.4 Other Risk Management 其 他 风 险 管 理
Some risks cannot be adequately managed by inspection alone. Examples
where inspection may not be sufficient to manage risks to acceptable levels
are: 一 些 风 险 不 能 单 独 被 检 查 得 到 充 分 管 理
a) equipment nearing retirement; 设 备 即 将 退 休
b) failure mechanisms (such as brittle fracture, fatigue) where avoidance of
failure primarily depends on design and operating within a defined
pressure/temperature envelope; 失 效 机 理 ( 如 脆 性 断 裂 , 疲 劳 ) 失 效 主 要 取 决
于 设 备 的 设 计 和 操 作 .
c) consequence-dominated risks. 结 果 支 配 风 险
In such cases, non-inspection mitigation actions (such as equipment repair,
replacement or upgrade, equipment redesign or maintenance of strict controls
on operating conditions) may be the only appropriate measures that can be
taken to reduce risk to acceptable levels. See Section 14 for methods of risk
mitigation other than inspection.
