Kind Code:
A1
Abstract:
[Problem] To provide art for formulating an equipment maintenance plan from the standpoint of improving the security of a plant. [Solution] A maintenance management method for a plant 1 for processing a fluid extracts a plurality of accidents that are expected to occur with equipment constituting the plant 1, and acquires both the frequencies of occurrence of accident-causing events that can cause the extracted plurality of accidents, and the probabilities of failure of safety devices for preventing occurrence of the accidents. Then the maintenance management method calculates risks which are values obtained by multiplying the frequencies of occurrence of the accident-causing events associated with each accident by the probability of failure of the safety device for the accident, and compares the calculated risks with a preset threshold value. Thereafter, the maintenance management method lists, as candidates to be subjected to maintenance work, the equipment and the safety device that are associated with each calculated risk that is greater than the threshold value.
