3Our Role
- Documented scheme for control and management of
external corrosion risks. - Integrated external corrosion management and
integrity. - Prioritised coatings, insulation and PFP
maintenance scopes. - Packaged information necessary for informed
decision making and budget justification. - Add on to integrity / work management system.
4Key features
- Integrity Focused
- Affordable (phased, low cost start-up and
maintenance) - Auditable line of sight from Safety Case to
activity - Justifiable, clear, costed plans
- Flexible (what ifs)
- Optimised strategy and budget costs
5METHOD - Focus on risk (from external corrosion)
Criticality
6Worksite information
Design specification Dimensions Pressures U Value
Element type and Duty Purpose (sets consequence
of failure)
Corrosivity Zone Corrosion rate
Probability of failure information Remaining
Corrosion allowance Required life
Reference Reports and photos
Loss to Date From condition information.
7Criticality Processing
- Probability of failure is related to the
elements tolerance to external corrosion related
to required life - Consequence of failure in terms harm (persons or
environment) and cost - Combined in a simple matrix to give the
Criticality rating
The matrix is weighted in favour of the
Consequence .
N.B. In this context, Failure is taken to be loss
of Fitness for Purpose (i.e. the potential for
failure).
8Condition
- Paint
- Corrosion Severity
- Wall Thickness
- Pit Depth
- Anomaly / Observation
- Penetrations
- Seals
9Planning (settings and choices)
Plan settings
- Least cost
- Least interventions
- Least metal loss
- Most coating life
- Appearance critical (e.g. for attracting 3rd
party customers)
10Stage 1- Choosing Strategy
- Set Criticality criteria (Client or Metacor)
- Set Integrity Criteria (i.e. Corrosion Allowance,
Corrosion Allowance diminution allowed) - Produce alternatives (e.g. Little and often, big
hit etc.) - Review and make / take decision on strategic
approach to maintenance
or
11Stage 2 Optimising Strategy
- Establish extent of maintenance required
- Optimise chosen strategy
- Build budget
- Produce listing and graphs for review.
- Present plans for review and approval.
12Stage 3 Executing Strategy
- Final optimisation (e.g. opportunistic access
availability etc.) - Package into Detailed Work Scope Packs - logical
work chunks for effective communication,
management control. - Define execution and quality specifications
13Integrating Internal and External Corrosion
Predictions
- Client data
- Internal corrosion monitoring and prediction.
- Metacor data
- External corrosion monitoring and prediction.
- Example
- 3nb Pipe, 3mm CA, 2.4mm Internal CA, 0.6mm
allocated to External CA. - Existing loss to date (internal) recorded.
- Predicted internal corrosion rate recorded.
- Existing external loss to date recorded.
- Metacor predicts external corrosion rate.
- Internal and external LTD and predicted corrosion
rates combined to give predicted retiral (loss of
fitness for purpose) date.
14Integrating Internal and External Corrosion
Predictions
- Current wall thickness / loss to date details
recorded in condition form. - Internal corrosion rates integrated within Metacor
15Integrating Internal and External Corrosion
Predictions
16Systems connectivity
- Metacor link to Management and other systems.
- Exchange box used to match other system data
fields to Metacor and vice versa. - User is informed that update available, and can
review before accepting. - Process ensures information transfer is secure
and neither other system data nor Metacor
database can become corrupt.

17Stage 4 Managing Strategy
- Load to MetacorWeb for
- Progress reporting / record as work completed
versus planned. - Remote access (onsite and contractor)
- Upload of quality and inspection documents /
photos. - Anomaly and condition reports
18Benefits
- Safety
- Less corrosion-related failures
- Less offshore ad-hoc labour
- Knowledge of risks to asset, environment and
personnel
19Benefits
- Cost reduction
- Less wasted painting costs clear focused scope
- Less administration clear management / scope
development and budgeting - Less logistics focused deployment not
scattered. - Less engineering assessment demonstrate
knowledge of condition - Less corrosion related repairs
