a pipeline integrity Management system (piMs) relies on
a number of core elements such as people, procedures
and methodologies, as well as data and software.
to be effective, a piMs must:
• have clearly defined objectives and Key performance
indicators (Kpis)
• Be supported by an effective staff organizational
structure and training program
• have good access to accurate and comprehensive
pipeline data
• Be aligned with existing operational and maintenance
procedures and practices
• Be supported by appropriate software enabling regular
review of pipeline risks and outputs that fit client metric
system; these reviews then form the basis for informed
decisions to ensure safe and economic pipeline operation
• Be regularly updated to incorporate changes such as
regulatory updates, technological improvements and
modified pipeline threats
as part of our service, we define procedures to enable
effective interaction between all piMs components. these
procedures aim to achieve all integrity objectives and
ensure that every single task performed is controlled, and
validated and that it contributes to integrity.
Based on broad experience in piMs implementation for
onshore and offshore assets worldwide, rosen defines
customer-specific processes taking into account inter-
national guidelines and codes.
our consulting team consists of experienced individuals
working in the fields of process safety, risk-informed
decision-making and management system audit and
evaluation.
During the implementation of a piMs, a specialized team
evaluates existing integrity management systems and
procedures as well as asset-specific information. on
the basis of this evaluation, established processes are
verified and measures recommended to continue
achieving goals related to safety, integrity management,
compliance and reliability.

• alignment of repeat inspection data by normalizing it
to common reference points (e.g., girth welds).
• automatic feature matching process, resulting in
calculated corrosion growth rates between inspection
intervals.
• raw signal data comparison, to validate the calculated
growth rates based on feature matching.
• feature resizing (where required) of selected features
conducted by data analysts to further validate corrosion
growth rates.
• Matching of other reported features (e.g., dents) to deter-
mine possible pipeline damage between inspections.

on the basis of the findings of integrity and Cga assess-
ments, future integrity planning makes recommendations
for future corrosion prevention and control methods. it
also provides the technical basis for defining repair and
maintenance plans to ensure safe and cost-effective
operation in future.
kEy StEPS INcluDE
• reviewing available pipeline data (e.g., above ground
surveys, Cp data, excavation data, repair/rehabilitation
data) and correlating it with inspection findings.
• estimating future growth behavior of reported corrosion
and its influence on the future integrity of the pipeline.
• provision of the technical basis for defining repair and
maintenance plans to ensure safe and cost-effective
future operation.
• Making recommendations for optimum re-inspection
intervals and the most appropriate inspection technology.
• recommendations for modifications/improvements to
current corrosion prevention and control measures.
External corrosion is one of the
primary threats to pipeline integrity
