Abstract: Presented by Hannes Viljoen at African Utility Week
With the current economic growth in South Africa equipment availability, reliability and operability in several business sectors, especially in the manufacturing environment is playing a vital role in the competitiveness of a company.
Plant availability, reliability and operability are strongly influenced by preventative maintenance. In order to incorporate the required preventative maintenance on a plant, several factors need to be exploited in order to keep the running cost of such a plant to an absolute minimum in the short and long term.
Factors influencing the preventative maintenance approach are typically:
- Outsourcing of maintenance
- Production demand at plant
In order to exploit these factors, a company needs to know the maintenance fundamentals and the procedures on the development of:
- Maintenance philosophies
- Maintenance strategies
- Maintenance plans
In terms of human resources, the necessary training and developmental requirements, need to be incorporated in the strategies in order to implement a “Maintenance Management System”.
This presentation will explain the basic concepts of a maintenance philosophy and maintenance strategies. It will also give an overview on the basic steps to be followed in the compilation of a maintenance plan.
The case study deals with a “Milling Plant” at an Electricity Power Generating Utility. A “Reliability Centred Maintenance” (RCM) maintenance philosophy is followed. The maintenance strategies that are supporting the maintenance philosophy include:
- Time based Maintenance
- Condition based Maintenance
- Design-out Maintenance
The maintenance plan that is supporting all of the above maintenance strategies is standing on four pillars:
The functional requirements of each pillar will be discussed, as well as the human resource requirements, computer database requirements and training and developmental requirements.
The presentation is aimed to give an overview on the practical implementation of a sound “Maintenance Management System”.
