Factors to RememberPlant and equipment, however well designed, will not remain safe orreliable if it is not maintained.

The general objective of the maintenance process is to make use of theknowledge of failures and accidents to achieve the possible safety with the

lowest possible cost.

The concept of risk-based maintenance was developed to inspect thehigh-risk components usually with greater frequency and thoroughness

and to maintain in a greater manner, to achieve tolerable risk criteria.

Risk-based maintenance methodology provides a tool for maintenanceplanning and decision making to reduce the probability of failure ofequipment and the consequences of failure.

Business Objectives and requirements

Risk Definition

What it means to you, in terms of

Your business

Your operations

Your people

And most of all your reputation


13/31

James Fisher




The overall goals/objectives need to be defined, such as .. Risk Assessment and Safety

The improvement in operational effectiveness of critical plant

The improvement in operational effectiveness of the main cost drivers

Environmental causes

The reduction in fuel and operational costs

The award of class CM Notation

The retention of the Companys reputation

The reduction in the overall maintenance budget

The business plan must be identified, funded and resourced

Establish the start position

Identify the end point

Understand the Gap

Identify and resource (funding and man power) to overcome the Gap.

Step 2 Determine Key Functional and

Performance Standards For all of the assets and systems identified in Step 1

Identify the function of the asset Identify the performance standard (s)

Step 3 Determine Plausible Functional

failures For all of the assets and systems identified in Step 1

Identify in what way each asset can fail to perform its function (s)

James Fisher


21/31

James Fisher



Step 4 Determine likely failure modes

and their effects For all of the functional failures identified in Step 3

What causes each identified functional failure? (These are the failure modesrelevant to the asset, including any that might be induced by human error)

What happens to the asset, the system and the surrounding environmentswhen each identified failure mode occurs?

In what way do the failure effects of each failure mode matter? (These are thefailure consequences in terms of hidden or evident, safety, environmental,operational or non operational criteria).

James Fisher

Step 5 Select Feasible and Effective

Maintenance Tasks For all of the functional failures identified in Step 3

How can each Functional failure be prevented? Identify Preventive Maintenance Tasks with associated task intervals

Identify Condition Monitoring tasks and techniques

Step 6 Schedule and Implement selected

Tasks For all of the Preventive Tasks identified in Step 5

Identify how Tasks will be scheduled Identify skill required

Identify training need

Identify Condition Monitoring technique delivery and assessment

Procure, install, train and instigate new techniques and tasks
