Pipeline Remaining Life & Replacement Engineering

Managing the integrity of onshore and offshore pipelines and flowlines through engineering assessment, inspection planning, and life-extension strategies.

Overview

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.

Scope Includes

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
