in the previous two columns, I discussed joint goals and how to promote
the operations/maintenance partnership through a different way of reporting
and solving operations as well as maintenance problems. In this article,
I will continue to elaborate on the vital relationship between operations,
maintenance, and engineering.
A JOINT VENTURE. One thing is to agree to that
operations and maintenance are equal partners in a joint venture resulting
in reliable production. Another thing is to make it happen, and, to make
it happen, you need to do things differently than you have done in a customer-supplier
relationship. For example, you should:
- Agree on the same goal-overall production efficiency (OPE).
- Achieve the right joint focus-total reliability. There is revenue
as a result of improved reliability. Improved reliability results in
lower sustainable maintenance costs.
- Solve problems-do not classify production losses by department.
- All of the above were explained in the August and October columns.
Other things you can do to promote the partnership are:
- Include operators in basic inspections and essential care of equipment
- Agree on guidelines for priorities of work requests
- Communicate production plans
- Create a joint shutdown schedule
Of course, the most important part of building the partnership is personal
relationships. However, organizations are changing, and, with the wrong
processes in place to promote a partnership, things will fall back to
a less effective work system.
INCLUDE OPERATORS. Where it is practical and
makes sense, operators should undertake some basic inspections of equipment.
If it is practical for an operator to do inspections, they should be taught
to do so. As a guideline-if an operator can be trained in an inspection
method in less than 15 minutes, he or she should be trained to do that
inspection.
A classic example is the inspection of a rotary steam joint for a paper
machine. It makes sense for a back tender to not only look at ropes, felts,
paper web, doctor blades, condensate returning through steam joint, etc.,
on the back side of a paper machine, but to also inspect the condition
of the carbon ring in the steam joint. Training operators on how to do
this takes less than five minutes.
As can be seen in the picture, a pin on the side of the joint housing
is indicating the wear of the carbon ring inside the joint. Where there
is less than a 1/8-in. distance between the housing and the locker ring
on the pin, the carbon ring needs to be replaced in the next shutdown.
With a good light source, an operator can check about five joints in each
direction when he or she is doing other operations inspections on the
backside of the paper machine.
This is a very good and reliable inspection and it is only one example
out of many that are logical to train operators to perform. By the way,
you might be surprised to know that many very experienced paper makers
have never heard of this basic inspection method; they still run joints
until they leak and cost 300% to 800% more to repair.
AGREE
ON WORK REQUEST PRIORITIES. First of all, maintenance work should
start with a work request, not a work order. A work request might or might
not turn into a work order.
If a work request turns into a work order, the execution should follow
jointly agreed upon priorities. It is a very good idea to develop these
together between operations and maintenance.
To sit down with your operations partner and agree on these guidelines
and then start using them jointly is one of the most hands-on and best
ways of making the partnership happen. I will be glad to send anybody
who requests it an example of a priority guideline. |
