Maintenance Plan


Maintenance Plan

structured and documented set of tasks that include the activities, procedures, resources and the time

scale required to carry out maintenance

Note 1 to entry: The maintenance plan should be thoroughly analysed and modelled to produce relevant

probabilistic results.


Note 2 to entry: The forecasted probabilistic results established at the design stage are no longer valid if the

maintenance plan which has been considered is not thoroughly applied in operation.

Note 3 to entry: The maintenance plan should cover policies for both preventive maintenance (e.g. testing) and

corrective maintenance (e.g. minimize downtime, restore lost redundancy).

Note 4 to entry: The maintenance plan is part of an overall Operations and Maintenance plan. It is sometimes

called “maintenance policy”.
