CORRISION GROWTH ANALISYS
A.Hak is capable of performing Corrosion Growth Rate (CGR) Analysis; either historical
(whereby only one inspection is required) or back to back (whereby two inspections are used).
This service grants pipeline owner/operators additional insight into the behavior of corrosion
on their assets. Many clients use CGR analysis as an additional layer of risk management by
looking closely at features that do not meet their excavation criteria at the time of inspection,
but are calculated to by the time of their next planned inspection. Conversely, A.Hak’s CGR
Analysis can also be used as input for deciding when to plan thenext inspection.
A.Hak has an internal policy whereby we notify clients immediately upon identifying
an unrepaired anomaly deeper than 80%, or that has a calculated burst pressure less than
the MAOP of the pipeline.
Some clients have their own immediate notification criteria and in these instances we adopt
the more conservative of the two.
Notifying clients immediately ensures these severe features receive an appropriate level of
attention and also allows pipeline owner/operators to act quickly on features that may leak or
rupture in the near future.
Every year we notify several clients of such features and every year we have clients grateful
for the advanced warning and their partnership with A.Hak.
