Efficient Plant February 2018 - 33
Asset-intensive operations, regardless of sector, can reap significant benefits
when appropriate personnel are able to access good equipment Bills of Materials.
Good BOMs Boost
MOST CMMS SYSTEMS have the ability to create Bills of Materials (BOMs) for equipment or assets. This type of BOM includes all the
components needed for a piece of equipment. According to information from Life Cycle Engineering (LCE.com, Charleston, SC), all types
of asset-intensive industries can reap benefits from good BOMs-with
one of the most important of those benefit coming in the form of
increased maintenance efficiency. Among other things:

EQUIPMENT BOMs CAN HELP THE
MAINTENANCE PLANNER PLAN A TASK
OR JOB FASTER.
Do your planners spend time looking at drawings, manuals, or
catalogs to find part numbers that could be right at their fingertips?
BOMs can be created for certain PM tasks, shutdowns, or redundant
tasks. Yes, it does take time to create and maintain good equipment
BOMs. If they aren't maintained correctly, confusion ensues and
end-user time is wasted.
EQUIPMENT BOMs CAN HELP
Do you have craftsmen working on back shifts, nights, or weekends?
Good equipment BOMs will reduce equipment downtime because,
regardless of the time that any parts are needed, they can be identified and procured quickly.
USING A GOOD BOM SYSTEM CAN HELP
MANAGE SYSTEM SUB-COMPONENTS.
Do you have sub-components with replacement parts that are hard
to identify? Consider a conveyor that uses lifts, curves, and belts of
different lengths or widths, gearboxes with motors, or a hoist made
of several components. The sub-component items can be broken
out into their own BOMs and become part of a sub-BOM for such
USING EQUIPMENT BOMs HELPS MANAGE
Do personnel ever decommission and remove equipment from the
plant floor? The associated spare parts can sit in the storeroom for
years, taking up valuable space. With good equipment BOMs, the
task of identifying spare parts that belong to a decommissioned
piece of equipment is a simple task. With a little cross-checking to
ensure that the parts aren't used on some other piece of equipment
or system, you're almost done-except for removing the items from
the CMMS and storeroom. This strategy helps reduce the total dollar
amount of a site's spare-parts inventory.
While it does take time to create and regularly update equipment BOMs,
the payoff is big. When BOMs are correctly set up and maintained, and
appropriate personnel know how to access them, an operation can look
forward to fewer headaches and a reduction in equipment downtime. EP
