In an RBM scheme, fa ilure corrective/preventive measures can be determined through the following actions: r Proactive maintenance r Redesign or modi cation r Operational condition changes The basic idea behind proactive maintenance actions is to prevent the failures before they occur or to detect the onset of failures in a suf cient enough time before they occur so that they and their effects can be managed and controlled. When the failure rates are too high or proactive maintenance actions are not enough, redesign or operational condition changes need to be applied. The proactive maintenance actions may be divided into the following four categories: (1) (2) (3) (4) Planned maintenance Condition-monitoring Combined planned maintenance and condition-monitoring Failure- nding.

Regarding maintenanc .net vs 2010 qr bidimensional barcode e in general, the overall objectives of the maintenance strategy selected will be various. These will include maintaining the process plant and equipment such that safety and asset integrity is at the appropriate high levels, the uptime is maximized, and the letter and spirit of all applicable states and regulations are met.

Maintenance is particularly important to equipment that is critical to safety and availability. These may include items that are important to the safeguarding of process or of oading equipment on the FPSO, the wells, subsea ow lines, manifolds, and risers. Therefore, a related criticality assessment is essential.

The approach to the maintenance will also need to consider both vendor recommendation and associated data reliability wherever available. Other factors to consider may include the following: r Potential for application of noninvasive inspection techniques and remote diagnostics r Appropriate levels of operator training and maintenance of related skills over time r Equipment layout and access. 11.6 Risk-Based Maintenance Planned maintenance Failure rate (t) Wear-out zone Operating age Figure 11.6.

6.5, we summarize each of the proactive maintenance-related actions. 11.

6.2 Planned Maintenance At a speci ed interval, planned maintenance (also called preventive maintenance ) is carried out regardless of the actual conditions of the components in question. When the failure type is of the wear-out type, the time interval for planned maintenance must necessarily be adequately short.

Planned maintenance may be further subdivided into two categories: restoration action and discard action. The restoration action is a scheduled maintenance task performed before the end of a speci ed interval by restoring the capability of components. The discard action is a scheduled maintenance task performed before the end of a speci ed interval by replacing components in question.

The failure patterns A and B illustrated in Figure 11.4 exhibit a clear failure life, but other cases may not be so distinctive in that regard. For planned maintenance action to be effective in managing and controlling the failure, the failure patterns must be characterized by pattern A or B, as shown in Figure 11.

6. After a planned maintenance action is performed, the failure rate may be reset, as illustrated in Figure 11.7.

. The interval of plan qr barcode for .NET ned maintenance action can be determined using the following data or information: r r r r r Information on fabrication and construction Expert opinion Published data Regulatory requirements Statistical analysis of failure history including data for mean time to failure. Two concepts are rel evant in the determination of the planned maintenance interval: the safe life limit and the economic life limit. Figures 11.8 and 11.

9 illustrate these concepts. The safe life-limit concept is applied when severe safety or environmental impacts or the highest risk events are anticipated. The action interval is set to ensure that there is little chance of failures occurring before the planned maintenance is carried out.

In general, the interval is set well before the mean time to failure. The economic life-limit concept is applied for all other failure modes. The action interval in such cases is determined on the basis of the economical points of the maintenance action and also the expected life of components in question.

In some cases, the action interval may be set to be even beyond the point of the mean time to failure.. Failure rate (t).
