Pipelines operate under pressure, geohazards and changing operating conditions. When corrosion, dents, cracks or other anomalies are detected, you need more than raw inspection data — you need an independent pipeline integrity assessment that shows whether the line can keep running safely, and under which limits.
NWE provides Pipeline Integrity Assessment Services that combine inspection data, defect assessment methods and relevant codes to support defensible run / repair / re-rate / replace decisions for onshore and offshore pipelines.
Our work helps operators:
A pipeline integrity assessment is typically required whenever the condition, loading or use of a pipeline changes in a way that could affect safety or compliance.
Typical triggers include:
In all of these situations, a structured integrity assessment provides quantitative evidence of risk and fitness-for-service, rather than relying on conservative assumptions or visual impressions alone.
NWE’s pipeline integrity work is focused on decisions and documentation, not just software outputs.
A typical Pipeline Integrity Assessment from NWE delivers:
The outcome is a defensible integrity position on each assessed segment or anomaly, linked to practical actions and timeframes.
NWE performs pipeline integrity assessments across a range of onshore and offshore systems, supported by its accredited inspection background and global project experience.
Typical pipeline systems:
Typical integrity threats addressed:
If your pipeline or threat scenario is not listed here, NWE’s engineers can review the available information and confirm whether a formal integrity assessment is appropriate.
NWE combines independent inspection heritage with dedicated asset-integrity engineering support for pipelines.
Key reasons clients choose NWE:
Clear communication for technical and non-technical stakeholders
Reports and consultations are structured so that integrity engineers, operations teams and management can all understand what has been found, what it means, and what should happen next.
Pipeline integrity rarely stands alone. NWE’s assessment services are often combined with:
These services ensure that inspection, analysis and risk decisions are aligned across your asset base.

Depending on the pipeline and threat, we draw on recognised standards and methods such as ASME B31.4 / B31.8, ASME B31G/B31.8S, API 579 / ASME FFS-1, BS 7910 and relevant DNV/CSA guidance, combined with client and regulatory requirements.
We typically require ILI or other inspection data, design and routing information, operating pressure/temperature history, material specifications and any existing integrity or incident reports. For unpiggable lines, we can work with direct assessment data and other field measurements.
An assessment is a focused engineering evaluation of the pipeline’s current condition and defects — essentially a detailed health check at a point in time. Integrity management is the ongoing programme that uses these assessments, along with inspection, maintenance and risk processes, to manage the pipeline over its full life.
Pipeline integrity assessments frequently use FFS methodologies for individual flaws or segments and then feed results into RBI and integrity management plans. FFS provides the defect-level answer (“Is this feature tolerable and for how long?”), while the integrity assessment and RBI place that answer into a system-wide risk and planning context.
Yes — provided the assessment is well-documented and based on recognised methods. Quantifying remaining strength, corrosion growth and consequence of failure supports risk-based justification for repair deferral or adjusted inspection intervals, in line with applicable regulations and company standards.
