Knowledge Based Asset Integrity™
(KBAI™)
KBAI™ is KBM's
patented risk-based asset modelling technology at the
core of the Arivu™ platform. The intelligence within the
KBAI™ modelling engine enables you to evolve your
existing reactive and time-based maintenance strategies,
and move into a risk-based asset management approach.
As you make this move, KBAI™ will improve critical asset
reliability and integrity while simultaneously optimising maintenance costs.
With KBAI™, benefit is measured as a
reduction in risk to your operation. For example, a
KBAI™ analysis may identify that a
$5,000 preventive
maintenance activity on a busy asset will reduce the
risk of an unplanned outage by
$10,000 and therefore
should be undertaken. Or a
KBAI™ analysis may identify that the same
$5,000
maintenance activity on a less busy asset will only
reduce risk by
$100, and therefore should not be
undertaken.
Traditional maintenance programmes are
founded on time-based inspection, time-based preventive
maintenance (pre-emptive replacement), and reactive
maintenance (repair after failure). A traditional
approach does not place a priority on incorporating both
risk of failure and the resulting business impact, thus
over allocating resources to low risk assets and under
allocating resources to high risk assets.
In contrast, KBAI™ is a dynamic
inspection and maintenance approach which determines
resource allocation based on risk. KBAI™ increases
resource allocation to high risk assets (where it is
needed most) and reduces allocations to low risk
assets. KBAI™ will typically increase the reliability
of critical assets and reduce expenditures on low risk,
non-critical assets.
The KBAI™ Risk Matrix
KBAI™ identifies
recommended inspection and maintenance intervals for
assets with the risk matrix. This characterises
the criticality of an asset, or the main groups of
components within an asset, by plotting the Probability
of Failure (PoF) against the Consequence of Failure (CoF).
Maintenance recommendations are then assigned according
to the criticality, with separate criticalities
calculated for the main groups of components within an
asset, where appropriate. An aging asset subject
to high usage and performing an important function might
be in the ‘high’ criticality category and thus require
frequent maintenance, while a similar asset, working in
conjunction with an identical standby asset, might be in
the ‘low’ category thus requiring infrequent
maintenance.
The PoF is driven by statistical
analysis from our global customer
and asset database, with a focus on Mean Time to Failure
(MTTF) for each asset and their components. This
information is reinforced with public data sources and
the insight from recognized Subject Matter Experts from
Lloyd’s Register. Over time, the KBAI™ regimes are
refined with further MTTF data collected in the program.
The CoF assessment models a combination
of factors to quantify an event based on availability,
safety, environmental, and political impact.
The CoF assessment can be driven by both
qualitative and quantitative modelling techniques. The
more complex quantitative approach provides the most
accurate estimates on the impact of an event, while the
less complex qualitative approach provides a range of
possible impacts and supports more subjective input.
The Bottom Line
KBAI™ offers a highly structured,
financially defendable asset
management approach to
clients in asset intensive industries. KBAI™ represents
the next generation of risk-based asset management
technologies and provides companies with a rapidly
implemented, practical and innovative solution for
applying proven risk-based asset management principles
across a large scale asset
base.
KBAI™ also supports the principles
within the guidance provided by British Standards’ Asset
Management framework, PAS55 and provides asset
intensive
companies with a quick journey to extracting economic
value from the physical asset base.
How to get it
KBAI™ is available
