Corrosion is a multilateral issue that concerns managers as much as engineers. In this very brief presentation, we will discuss what we call as "Corrosion Knowledge Management

1. Corrosion Knowledge Management:
Corrosion for Managers with little or no
technical knowledge of corrosion

5. HOW TO DEAL WITH CORROSION?
There are two ways to do this:
1. Corrosion management (CM)
 Technical treatment of corrosion by engineers and technologists
 Characteristics:
• Use of a too- technical “jargon” only understanable by their
fellow-engineers.
• Main concern is to control the “RISK” of corrosion
2. Corrosion Knowledge Management (CKM):
 Managerial Treatment of corrosion
 Characteristics:
• A tool-box necessary for top and middle managers
• Main Concern is to control the “Cost” of corrosion

7. WHAT IS CKM?

8. WHAT IS CKM?
CKM is a strategy that Managers need to follow to deal with
corrosion ,
It theorises the methodology required by policy-maker managers
and top managers to save on both economical & ecological costs of
corrosion
CKM uses the principle of “Occam’s Razor”:
“Out of several explanations for an occurrence,. the simpler one is
usually better”.
 IF THE MANAGEMENT IS CONVINCEC ABOUT ENGINEERING
IMPORTANCE OF CORROSION, THEN CORROSION WILL BE
CURED.

9. WHAT IS CKM?

10. Phase 1: The Manager has to justify why corrosion has to be considered seriously.
For this, He will need to know the “size of the cost” imposed on his assets by
corrosion
Phase 1-1: Size of the economical cost---- for this the manager will need to have
an economic model of the cost
Phase 1-2: Size of the ecological cost --- for this the Manager will need to have
an ecological model of the cost
For phase 1 and its components, The manager will need to see how the activities of
his power plant cause ecological/economical costs.
Phase 2: After both the models are prepared, they will be applied to find out the
size of the costs.
The outcome of Phase 2 will be expressed as in $ (or any other monetary unit)

11. Phase 3: The Manager will engage a multi-disciplinary team to apply the four
principles of CKM:
Phase 3-1: Engineering Discipline:
Phase 3-1-1: to define the Corrosion system
Phase 3-1-2: to define the Modeling of the corrosion processes
Phase 3-2: Legal consulting Discipline: to define the framework required for
information transparency
Phase 3-3: Data mining Disciline: to define the size of the “dark data” vs. “ White
data”, that is, the data that has not yet been used(but gathered) to the data that is
currently in use.
Phase 4:Based on the size of the costs, The Manager will re-arrange his seven
resources

12. PRINCIPLES OF CKM HOW TO JUSTIFY:
HOW TO APPLY
Phase 5-1: As long as the size of the costs of corrosion is known, The manager
can estimate the budget that will be required to rectify corrosion and its ecological
as well as economical impacts (Budget)
Phase 5-2: The Manger will estimate how many experts will be needed to deal
with corrosion. If the dominating corrosion process is microbial corrosion for
example, The manger will employ more corrosion engineers with hands-on
experience on microbial corrosion, (Expert Team)
Phase 5-2-1: in case employment of new employees is not possible, they can be
recruited on contact basis,
Phase 5-2-2: In addition to contracting/employing, The Manager would want to
have highly experienced consultants with expertise on microbial corrosion by his
side.
Phase 5-3: The Manger may also want to train his current technical /non-technical
employees to fill in the knowledge gap they have by either refreshing
courses/workshops or basic trainings (Training)

13. Phase 6: The Manager will only fund the research projects whose focus is on
finding applicable solutions to the corrosion problems of the power plant and its
various aspects (Research)
Phase 7: The way the corrosion related data will be converted into white (in-use)
information must be acquired, sorted out and stored and how much of it in what
way must be revealed to prevent the re-occurence of problems will be handled
(Information)
Phase 8: In what ways the technical/non-technical staff must be energised and
mootivated about their responsibilities towards controlling the size of the corrosion
costs will be the focus of this phase (Energy)
Phase 9: How to make repairs/shut downs much shorter in time length and how
to mobilise the at-hand facilities to control the size of the corrosion costs will be
contemplated in this phase (Time)

14. MONITORING OF CKM
The economical-ecological models will be reviewed in regular periods.
The review will be performed by a mixed committee from both the power plant
team (Management-technical) and an independent set of experts.
The outcome of the review will be applied after all memebrs agree to its
applicability.
The main KpI buy which a CKM model success must be measured is:
-How much overal corrosion rate has been reduced (by applying 20-80 principle,
the most critical equipment/zones are selected and the corrosion rates are
measured there)
-How much reduction in economical costs
-- How much reduction in ecological costs

16. SUMMARY
1. Corrosion is an issue that has economical –ecological impacts in
addition to technical problems it makes. Some of the consequences
from corrosion may include delays in delivering services, imposing
unnecessary overtime costs and waste of Energy.
2. Being a multi-lateral issue, corrosion needs to be handled by both
technologists-engineers and top/senior managers
3. While engineers can apply corrosion management (CM) methods
which are widely known, managers need to apply corrosion knowledge
management (CKM) techniques
4. CKM aims at reducing the (economical + ecological) costs of
corrosion whereas CM only aims at reducing its engineering risk.
5. CKM has four principles and has to be applied to seven management
resources to re-arrange them to deal with corrosion thoroughly.
