There are however up front costs for organisation and training and for the purchase of appropriate instrumentation. There are operational circumstances which can favour or retard the potential for the introduction of condition-based maintenance. Table 11.2 Factors which can assist the introduction of condition-based maintenance Factor Mechanism of action Where a safety risk is particularly likely to arise from the breakdown of machinery Typical examples are plant handling dangerous materials and machines for rhe transport of people. Where accurate advanced planning of maintenance is essential Typical examples are equipment situated in a remote place which is visited only occasionally for maintenance and mobile equipment which makes only occasional visits to its base. Where plant or equipment is of recent design and may have some residual development problems Condition monitoring enables faults to be detected early while damage is still slight thus providing useful evidence to guide design improvements. It also improves the negotiating position with the plant manufacturer. Where relatively insensitive operators use expensive equipment whose breakdown may result in serious damage Condition monitoring enables a fault to be detected in sufficient time for an instruction to be issued for the withdrawal of the equipment before expensive damage is done. Where the manufacturer can offer a condition monitoring service to several users of his equipment The cost to each user can be reduced in this way and the manufacturer gets a useful feed-back to guide his product design and development. Where instruments or other equipment required for condition monitoring can be used. or is already being used for .
