Risk-Based Inspection

12.3.2 Using Risk Assessment in Inspection and Maintenance Planning
运 用 风 险 评 估 于 检 查 和 维 修 计 划
The use of risk assessment in inspection and maintenance planning is unique
in that consequence information, which is traditionally operations-based, and
POF information, which is typically engineering/maintenance/inspection-based,
is combined to assist in the planning process. Part of this planning process is
the determination of (1) what to inspect, (2) how to inspect (technique), (3)
where to inspect (location), and (4) how much to inspect (coverage).
Determining the risk of process units, or individual process equipment items
facilitates this, as the inspections are now prioritized based on the risk value.
The second part of this process is determining when to inspect the equipment.
Understanding how risk varies with time facilitates this part of the process.
Refer to Section 13 for a more detailed description of inspection planning
based on risk analysis.
