PM
Optimisation is a process that has become very popular
worldwide as a cost effective and practical alternative
to RCM. It has found great success in the following
instances:
·
In organisations that have
existing plants with existing maintenance programs,
where the situation requires a rationalisation and
review of current PM reliability rather than a
zero-based start-again method, and
·
In organisations that are
expanding or replacing current assets and have a need to
build a reliability program for these assets. They can
do this quickly and effectively based on the knowledge
that they, or someone else, currently have by virtue of
owning or operating similar assets.
The paper
presented takes two case studies. Both are from the
mining industry however the industry sector does not
much affect the process or the results. One of the
cases is surrounds an analysis project that was
completed prior to the commissioning of the equipment.
The other was done nearly two years after commissioning.
In both
cases, it was found that the vendor recommendations
needed significant adjustment to suit site conditions.
The PM Optimisation approach was found to be six times
faster than RCM and in theory produced the same results.
