Importance of Assets
• Assets are acquired for their ability to
produce the product on which an
organisation base its existence.
• Maintenance must focus on preserving
our assets.
• Maintenance is an insurance against
Risks.

ROOT CAUSE ANALYSIS
Monthly Reliability / weekly report to include a spreadsheet that displays the
following info:
No of trips on all main pumps
Trip stats of all main pumps
Temperature
Vibration
Low Suction
Eskom Trips, etc
 If a main pump trips more than 2 times for the
same reason within 30 days.
 If reliability for the pump set drops below the 12
month average as per internal target
 ALL MAJOR FAILURES
Reliability Report to
highlight conditions that
may require further
Investigation using Root
Cause Analysis.

Note:
Where failure of a system or equipment has
severe safety, environmental or financial
consequences, RCA’S must be done to eliminate
recurrence or manage the situation.

Follow up to ensure
that all solutions have
been implemented
