Pipeline Remaining Life & Replacement Engineering
Managing the integrity of onshore and offshore pipelines and flowlines through engineering assessment, inspection planning, and life-extension strategies.
Pipeline Integrity Management
We support operators in managing the integrity of onshore and offshore pipelines and flowlines through engineering assessment, inspection planning, and life-extension strategies. Our services help identify degradation mechanisms, evaluate anomalies, and develop practical mitigation or replacement strategies to maintain safe and reliable operation of aging pipeline infrastructure.
Corrosion management programs for pipelines and flowlines, including internal and external corrosion assessment
Inline inspection (ILI) program support, including tool selection, run planning, and data interpretation
Pipeline anomaly assessment, including corrosion defects, dents, gouges, and crack-like indications
Fitness-for-service and remaining life assessments for degraded pipelines
Routine pigging strategy development, including cleaning and intelligent pigging programs
Composite repair design and evaluation for corrosion defects and localized damage
Pipeline rerouting and replacement studies where deterioration or operational changes require system upgrades
Pipeline replacement and rehabilitation engineering, including structural verification and constructability considerations
Inspection and monitoring planning, including risk-based inspection strategies for pipelines and flowlines
Failure investigation and root cause analysis for pipeline incidents or integrity threats
Cathodic protection assessment and corrosion mitigation strategies
Pipeline integrity management system (PIMS) development
Pipeline risk assessment and consequence modeling
Third-party damage risk evaluation

Pipeline Remaining Life & Replacement Planning
Operators often know a pipeline is aging or deteriorating, but they struggle to answer the key questions:
How long can we safely operate it?
When must we replace it?
What is the most cost-effective strategy?
We provide the engineering rigour and clarity to answer these questions — with recommendations that are practical, defensible, and aligned to international standards.
Pipeline Remaining Life & Replacement Engineering
We support operators in evaluating the structural integrity and remaining service life of aging pipelines and flowlines, enabling informed decisions on repair, replacement, or rerouting strategies. Our assessments integrate inspection data, corrosion trends, and structural analysis to determine the safest and most cost-effective approach to managing deteriorating pipeline infrastructure.
Remaining life assessment using corrosion growth modelling
Structural integrity evaluation of pipelines with metal loss or damage
Fitness-for-service assessments in accordance with API 579 / ASME FFS-1
Evaluation of inline inspection (ILI) results and anomaly growth trends
Pipeline repair vs replacement decision analysis
Development of phased replacement strategies for aging flowline networks
Engineering assessment of pipeline rerouting or reconfiguration options
Support for pipeline abandonment or decommissioning planning
