AwarenessCost Vs. Reliability


Reality for Plants


Which Cost is Most Importan?

Maintenance Cost?Maintenance Cost per Ton?

Total Cost per Ton?Total Cost?


Three ways to reduce maintenance costs

1. Cut the cost

2. Reduce the need for maintenance

3. Execute remaining maintenance more efficiently.

Deferred maintenance leads toshort term savings and long term higher costs.

Procurement based on Life Cycle Cost.Maintenance Prevention

Lubrication, Alignment, Balancing, Operating practices.

Inspect, Prioritize, Plan, Schedule, Record, Analyze, Improve.


CUT COSTNO OTHER

IMPROVEMENT

Wrong Turn

1. Cut Cost2. Less Repairs and

PM* are Executed3. Reliability will slowly

falter4. Reliability will falter

quicker5. Maintenance repairs

become reactive6. Cost of repairs, lost

production , and spares go up

7. Reliability become worse due to completely reactive work cycle

8. Cost go up even more*PM = Preventive Maintenance


Right Strategy 1. Inspect equipment better

2. Failures are identified before break down

3. More lead time to plan & schedule

4. Reliability improves

5. Cost may go up due to repairing more for a while

6. Reliability goes up

7. Cost follows due to fewer break downs

Average Market Price: $595 per tonLess Variable Cost/ unit: $296 per tonContribution tocover fixed costs= $299 per ton.

Production 2006: 329,000 tons / year

One percent increase in output is 1% * 329,000 = 3290 tons

Additional PROFIT for 1% increase is: 3290 * 299 = $984,000 ANNUALLY!

• Your Maintenance and Storeroom cost is about 60 Millions Year.

• How would you reduce this cost?• What happens to that cost if reliability improves

Work Request and Priority Guidelines

Priority Example of Failure or Incident Maximal time in backlog

Is the job necessary to do? Yes No On Hold

1 Immediate safety risk Immediate risk of environmental damage Immediate risk of quality losses. Critical equipment down Short failure developoing period

Immediately. Will break other less important ongoing work.

2 Critical equipment is running at reduced speed Critical equipment is running in manual mode Manageable safety risk PM activity Mandatory inspections Failure developing more than 1 week

1 day - 1 week

3 Critical equipment running on spare equipment Failures that need correction Spare equipment out of function Leaks Failure development more than 1 month

1 week – 1 month

4 Improvement work - expense. Improvement work - capital

> 1 month

What to do

Best OrganizationsDo it.


Do Work

Even with good skills, people can not be more productive than the system they work in allows them to be.

People’s performance is often limited -not so often by their skills - but more often by the system they work in.


Reliability and Maintenance Improvement Process

It is the responsibility ofMANAGEMENT

to develop, institute and continuously improve systems and

procedures.


PRODUCTIVE or NOT?

Busy people are not necessary PRODUCTIVE

PRODUCTIVE people are busy with the Right Thing.


- Maintenance Crafts People?- Spare Parts Management?- Project Engineers?- Maintenance Managers?- Operation Managers?

You do not get what you ask for.You get what you recognize.
