ROSEN: LEADING THE WAY IN INTEGRITY
MANAGEMENT
The safe and ecient operation of major transmission
pipe lines is an important issue for many stakeholders,
including pipeline operators, landowners, regulatory
bodies, national and local governments, and the general
public.
At ROSEN, we provide specialized engineering, integrity
assessment and data management services that support
operational decision-making.
The key aims for pipeline operators are to
•reduce downtime due to unforeseen events
•define cost-eective inspection plans and
inspection intervals
•avoid unnecessary repairs and interventions during
standard operation
•extend asset life without compromising the principles
of safe operation

Reduction of Downtime
Downtime
These objectives are influenced by a range of legal and
financial factors, including
•compliance with legislation and company policies
•maximizing asset value and production targets
•operational life extension
•centralized approach for integrity management
The ultimate driver for us is to help our customers
balance these factors and make informed decisions to
ensure that they meet their business targets
while maintaining a safe and reliable asset base that
does not harm the environment.

DRIVERS AND POLICIES: HOW ROSEN CAN
HELP ENSURE COMPLIANCE WITH INDUSTRY
REGULATIONS
Codes and standards issued by regulatory bodies provide
guidance to pipeline operators on how to maintain the
integrity of their assets. ROSEN’s product and service portfolio is aligned with core industry framework documents
and codes.
System definition and data gathering
ROSEN supports its clients in reviewing and implementing
their integrity programs down to the creation of integrityrelevant procedures and processes.
Threat assessment
Adopting both qualitative and quantitative approaches,
we utilize the data and subject matter expertise of our
engineers and our clients to determine the presence of
potential threats along a pipeline route.
Risk analysis and inspection strategy
On the basis of an evaluation of potential threats and the
likely consequences of specific failure events, ROSEN
assists customers in implementing risk-reduction and
mitigation measures. As part of this service, we determine
the most cost-eective inspection strategy including
the most appropriate technology for assessing the
identified threats.
Action plan execution
In addition to our best-in-class in-line inspection services,
ROSEN oers further inspection measures that help
pipeline operators identify and verify threats. Examples
are above-ground survey projects, geotechnical assessments as well as remote sensing projects.
To optimize corrective measures based on inspection
findings, ROSEN provides follow-up analysis such
as fitness-for-service assessment and corrosion
growth studies.

Response to findings
ROSEN integrity specialists have extensive experience
in selecting the most appropriate rehabilitation method
for identified defects. In addition, we ensure that the
right data are collected during field verifications. The
information collected on site provides highly useful input
for assessing the quality and reliability of inspection
data and can additionally be used for further analysis.
Information analysis
ROSEN Business Consultants support the process of
reconciling integrity aspects with commercial
considerations. This reconciliation is achieved, for
example, by connecting our integrity systems to
SAP and Maximo, resulting in a centralized approach
for the Pipeline Integrity Management System (PIMS).

ROSEN INTEGRITY PRODUCTS AND SERVICES
PORTFOLIO: WHAT ROSEN CAN OFFER
Engineering and consultancy services
Based on our strategic partnership with MACAW
Engineering, we provide the following integrity based
services:
•ILI feature review and corrosion mechanism diagnosis
•Fitness For Purpose (FFP) assessment
•Future integrity management planning
•Corrosion Growth Assessment (CGA), including raw
signal data comparison
•Remaining life assessment
•Risk assessments and Risk-Based Inspection (RBI)
implementation

including reviews and recommendations
•Materials and welding consultancy
•Failure investigation
(including laboratory based services)
Integrity software implementation services
The ROSEN Asset Integrity Management Software
(ROAIMS) for pipelines is recognized as one of the industry’s best integrity management software suites. Utilizing
ROAIMS, we perform the following activities with the final
goal of creating auditable standards of integrity:
•Client-specific enterprise interfaces
•Client-specific algorithms for defect and risk assessment
•On-site and o-site data gathering and processing
•Dataqualityevaluation(QA/QC)
Data management services
•Data services: from high consequence area evaluation
to comparison of ILI data with as-built information,
ROSEN performs various data analysis services. The
analysis is typically conducted using a structured data
model such as PODS.
•Geo-services: using GIS technology, we perform
geotechnical threat and environmental change
assessments; also pipeline movement is analyzed
combining inertial mapping results from in-line
inspections with satellite and aerial imagery.
RISK ASSESSMENT
Risk assessment involves identification and evaluation
of threats, failure modes and potential consequences
for pipelines. Based on methodologies customized
to client system requirements, such risk assessment
provides the clear direction and priorities required
for the development and implementation of Integrity
Management Plans (IMP).
Ensuring compliance with the relevant safety, health,
environmental protection and quality regulations, risk
assessment and management aim at improving security
of supply, maintaining safe operations, reducing risk
to human health, and avoiding environmental damage.
KEY STEPS INCLUDE:
•Holding client workshops to determine available data
and risk model customization requirements
•Client system definition and segmentation
•Threat/hazard identification
•Threat susceptibility assessment
•Consequence analysis
•Risk result presentation as per client-specific
requirements
•Prioritization of future integrity actions
IMMEDIATE INTEGRITY ASSESSMENT
Immediate integrity assessment provides expert analysis
of inspection findings and corrosion mechanisms to
determine the current integrity of the pipeline (i.e., at the
time of the last inspection).
KEY STEPS INCLUDE:
•Summarizing feature distributions and identifying
activity hot spots
•Characterization and diagnosis of reported corrosion
•Consideration of High Consequence Areas (HCAs) for
activity prioritization
•Assessment of metal loss features in accordance with
applicable international/regional codes
•Assessment of other features (e.g., dents) reported by
the inspection
•Identification and prioritization of features requiring
repair
Utilizing our product ROAIMS for the analysis execution,
the client decides whether results are provided in analog
report or in a populated version of the software.
Risk matrix is one of the main tools used
to visualize assessment results.
