LIKE PREVENTION, A RATIONAL
MAINTENANCE PROGRAM IS THE
Prevention is a health care principle that has a direct analogy
to a professional O&M organization. Simply put, this is the
maintenance side of the business.
Various facilities follow a wide variety of approaches, with
too many close to one end of the spectrum: run-to-failure or
breakdown maintenance. The other end of the spectrum —
serving/replacing components too frequently — also
is undesirable, though this is seldom seen in the
A robust O&M organization will steer a middle course,
generally tailoring and adopting a programmatic
approach that uses a computerized maintenance
management system (CMMS) to meet the specialized
needs of the facility. These systems are adamantly not
one-size-fits-all. Sophistication of the CMMS should
track the complexity of the plant and systems it relates
to. Other factors should be taken into consideration;
the level of mission-criticality that a facility system serves, for
example, will drive things such as inventory of spare parts and
maintenance frequency. Once again, a professional approach
to operation and maintenance will develop and incorporate the
right prescription for programmed, preventive maintenance.
Diligent facility O&M — like diet, exercise and prevention —
takes commitment and constant vigilance. It’s what happens
between the doctor’s visits and capital projects. It may not be
easy, but if performed well, good operation and maintenance
routines will help keep you, and your plant and facility, out of
the emergency room or ICU.

YOUR AIRPORT’S HEART:
FUEL PUMPING FACILITY
By Grant Smith, PG
An airport’s fueling system is analogous to a person’s
circulatory system. Fuel is the lifeblood supplied to
aircraft, provided throughout an airport using a fuel
storage and hydrant distribution system. And critical is
the pump pad, the heart of the fuel system.
Depending on the size of the
airport, the pump pad can be
from three to 18 pump-and-motor combinations that can go
from several hundred to several
thousand gallons per minute
(gpm), depending on demand.
The pump pad at Los Angeles
International Airport, for example,
is designed for up to 16,000 gpm.
The pump pad typically has a suction header that brings
fuel from the fuel farm storage tanks through filtration
and flow control valves. Pumps push fuel to the hydrant
system around each terminal to the gate, relying upon
sophisticated controls to maintain a constant pressure
of up to 150 pounds per square inch (PSI).
Burns & McDonnell both designs and retrofits new
pumping systems and older ones. Burns & McDonnell
recently completed a design-build turnkey upgrade of
the 35-year-old pump pad at Salt Lake City International
Airport, adding pumps and motors driven with variable
frequency drive (VFD) motor controllers. The upgrade
— call it a successful quadruple bypass surgery —
has reduced the system’s energy costs by 30 percent,
without service interruption.
