Reliability Centered Maintenance (RCM) And Total Productive Maintenance Analysis

In the maintenance environment it is important to have a clear understanding of the layout of maintenance strategies and the techniques that form the basis of the strategies. The different maintenance techniques namely, preventative, reactive and proactive maintenance are not so effective if used independently, but as a combination it serves as a powerful maintenance tool (Conradie, 2015). The cold box consists of sixteen main equipment where it can be divided into categories to differentiate what strategy will be most sufficient for the equipment in the SASOL environment. An accurate risk assessment needs to be conducted on all the main equipment as well as the sub components to determine the impact of a breakdown on the SASOL production and safety environment. In figure 5 the maintenance techniques is shown and will be discussed in this section.The two most commonly known maintenance strategies are Reliability Centered Maintenance (RCM) and Total Productive Maintenance (TPM). The strategies are used to determine the maintenance task, frequency and sequence. The failure need to be identified first and then determine the impact of the failure on the production and
The best way to describe preventative maintenance is from the illustration in figure 7. In the figure P indicate the point where potential failures might occur and point F indicates the point where a functional failure might occur. The repair of should be done in the P-F range before the breakdown happen (Plucknette, 2010). The mean time between failures can be determined by active online monitoring techniques which will be beneficial to implement a reliable maintenance strategy with correct shutdown intervals. In cases where breakdown occurs before the F point in figure 7, the maintenance strategy should be revised and all failure modes should be
