22 | July - August 2018 | www . machinerylubrication.com Imagine an operation in which there are no lost- time accidents, overall equipment effectiveness (OEE) is increasing, and there is a plan to address the skills shortage. ese sites do exist, and chances are they're using procedure-based maintenance. is type of main- tenance simply involves having all maintenance activities documented in a procedure. The procedures are followed step by step when conducting breakdown, corrective and preventive maintenance. is level of operational excel- lence comes with discipline, not just discipline that deals with people doing what they should be doing (or not doing), but discipline to the process and eliminating variation. at is the goal of procedure-based maintenance: to eliminate varia- tion in all aspects of maintenance, including data collection, repairs, calibration and commissioning. Another goal of procedure-based maintenance is to eliminate and reduce the odds of mistakes by maintenance staff. By ensuring that all activities are performed the same way, organizations can accomplish three key deliverables: build a knowl- edge library to survive the skills gap, identify key areas of variability and reduce that variability to achieve consistent outcomes from activities, and minimize the odds of a mistake during maintenance activities. The use of procedures must be thought out well in advance. Without this thought-out approach, the adoption of the procedures will fail. e procedures need to be orga- nized so they can be quickly located. ey must be written in a way so there is no misinterpretation of the task's meaning and so non-native English speakers can understand. Lastly, they must be utilized by the staff, with feedback captured and used to improve them. History of Procedures in Maintenance e use of procedures can be traced back many decades, and the results speak for themselves. Consider the U.S.S. Thresher, which was lost along with 129 lives on April 10, 1963. An investiga- tion into the loss of the submarine concluded that it was the result of flooding most likely caused by the failure of a seawater system component that may have been reinstalled improperly during a shipyard overhaul. There were additional factors, but the primary finding was that the component was reinstalled incorrectly.
