Unfortunately we have had to postpone this webinar due to our speaker being taken ill. We are hopeful that we can arrange a new date early in the new year.

This presentation outlines the approach taken to improve spares inventory management and define sparing requirements within a client’s computerised maintenance management system. Reviews of materials for each equipment item (bills of materials) were necessary, and where required the client’s master list of materials was updated to capture attributes and specifications of missing materials. Having established the completeness of the bills of materials, maintenance procedures were used to identify relevant spare parts required for planned maintenance at each equipment location. The final stage of the project involved optimising spare material quantities using analytical methods, to minimise under- or over-ordering for maintenance materials. To carry out this analysis, equipment criticality ratings needed to be determined using a high-level failure modes, effects and criticality assessment (FMECA).

The project covered three maintenance regimes. Two of these maintenance regimes are carried out at pre-defined intervals determined by the client’s operations and maintenance strategy, namely preventive and on-condition maintenance. Ad-hoc replacement of parts following failures are also considered in the analysis, using historical work order data to account for corrective maintenance.

Registration now stopped.

The webinar will be presented by:
