2.3.3 KPI-3 Safety-Critical Maintenance Backlog The KPI-3 produces a report of the total number of backlog hours for safety-critical maintenance that is beyond its planned completion date. This excludes backlog maintenance that has been subject to a formal and robust deferral process involving relevant technical or engineering authorities. As can be seen in figure 10 below, the data show a seasonal (cyclic) nature probably reflecting campaign maintenance patterns (for example, planned major maintenance shutdowns). Maintenance specialists attend the Oil & Gas UK KPI work group meetings and agree that, although we should always strive to reduce and minimise backlog, the levels of backlog experienced are tolerable.

However, it has now been recognised that reporting the backlog in terms of man-hours alone is not entirely helpful to our understanding of its significance. Changes are being made to the scheme to show backlog as a percentage of total planned safety-critical maintenance. This is likely to be more relevant and meaningful in reviewing and assessing maintenance backlog, and will be reflected in future reports.
