7.4.4 Operating Time Period 操 作 时 间 段<br />

The unit run lengths of the selected process units/equipment is an important<br />

limit to consider. The RBI assessment may include the entire operational life,<br />

or may be for a selected period. For example, process units are occasionally<br />

shut down for maintenance activities and the associated run length may<br />

depend on the condition of the equipment in the unit. An RBI analysis may<br />

focus on the current run period or may include the current and next-projected<br />

run period. The time period may also influence the types of decisions and<br />

inspection plans that result from the study, such as inspection, repair, replace,<br />

operating, and so on. Projected operational changes are also important as<br />

part of the basis for the operational time period.<br />
