Based on the risk-versus-cost approach in Tier Three, condition-monitoring
testing or proactive-maintenance tasks aren't performed unless they can be
economically justified.

WHILE YOUR SITE'S condition-monitoring efforts are probably
providing value, a frequent question from management is, "How
much?" Jason Tranter of Mobius Institute, Bainbridge Island, WA,
and Melbourne, Australia (mobiusinstitute.com), offers a quick way
to answer that question. In articles posted on his company's recently
launched CBM Connect website (cbmconnect.com), Tranter
discusses condition-monitoring programs in terms of these three
increasingly intensive-and value-adding-tiers:

The emphasis in Tier One is on detecting failure. You could
argue that the organization is implementing advanced reactive
maintenance, i.e., reacting to a technician's warning of impending
failure instead of an operator's warning or the catastrophic failure
of the equipment. Technician warnings are clearly valuable. You're
avoiding secondary damage and downtime, and, if such warnings
come early enough, you can reduce spare-parts inventory and
provide time for proper planning and work scheduling.
Rather than simply detecting faults, Tier Two puts emphasis on
identifying and, thus, avoiding the root causes of failure, albeit
just within the condition-monitoring sphere of influence. Precision alignment, balancing, and lubrication will reduce failures.
Detecting and correcting resonance, looseness, and soft foot will
reduce failures. Helping to develop and execute a QA/QC program
on work performed by the organization and on incoming new
and overhauled equipment will also reduce failures. By avoiding
failures, you are reducing risk, as well as costs associated with
repair/replacement of equipment that caused the fault to develop.

TIER THREE

Strategic and well structured, a Tier-Three condition-monitoring
program strives to help an organization achieve its business
goals. Programs in this tier understand the value of reliability
improvement and deliver clear, actionable information about the
health of equipment and corrective actions to take.
Tier-Three programs move condition monitoring into the realm
of condition-based maintenance (CBM). Here, the maintenance
department doesn't touch equipment unless the condition-monitoring department considers it necessary (for equipment identified
as having "random" failures or detectable age-related failures). In
addition, condition-monitoring analysts look for the root causes
of failure, and the maintenance department corrects them at
the appropriate time. As part of this approach, it's necessary to
understand various organizational priorities, including downtime
reduction, quality improvement, cost reduction, and asset-life
extension. It also requires an understanding of risk and criticality
(see figure), and prioritizing and scrutinizing all activities.

Tranter's short- and long-form articles on this topic include more
details for those who want to take their sites' conditionmonitoring programs to Tier-Three. Find them at cbmconnect.com/
