Non-intrusive insight into deposits, integrity risks, and flow assurance—without shutdown.
Subsea pipelines are the lifelines of offshore oil and gas production—transporting hydrocarbons across long distances under extreme pressure, temperature, and environmental exposure. Any loss of integrity, undetected deposit build-up, or unknown internal condition can lead to unplanned shutdowns, production losses, or serious safety risks.
Scansolution Process Diagnostic Services provide operators with non-intrusive, data-driven insight into subsea pipeline condition, enabling informed operational decisions without cutting, depressurising, or intrusive intervention.
Traditional subsea inspection methods focus primarily on external visual condition—marine growth, coating damage, or free spans. However, many of the most critical integrity and operability risks originate inside the pipeline system, including:
These internal conditions cannot be reliably identified through visual inspection alone.
Scansolution applies radiation-based, non-intrusive scanning techniques to determine internal deposit presence, distribution, and severity within subsea pipelines.
Operational value includes:
This allows operators to validate flow assurance assumptions without opening or cutting the line.
Lost or immobilised pigs and isolation tools pose major operational risks—particularly when valve operations cannot proceed safely.
Scansolution’s diagnostic scanning enables:
This capability restores operator confidence and shortens recovery timelines.
For insulated subsea pipelines, annulus water ingress can significantly reduce thermal efficiency and accelerate corrosion risk.
Scansolution diagnostics can:
The result is targeted repair planning and improved long-term integrity assurance.
Scansolution subsea diagnostic systems are designed to integrate seamlessly with ROV deployment, allowing inspections to be carried out as part of routine subsea campaigns.
Key advantages include:
Scansolution subsea pipeline diagnostic equipment has been successfully deployed in water depths exceeding 1,500 metres, demonstrating reliable performance under ultra-deepwater operating conditions.
Despite the challenging subsea environment—including high hydrostatic pressure, low temperatures, and limited accessibility—the diagnostic surveys delivered clear, actionable results that met the customer’s defined scope of work. These outcomes enabled confident decision-making related to pipeline condition, integrity assurance, and operational planning.
This proven deepwater capability reinforces Scansolution’s ability to support deepwater and ultra-deepwater subsea pipeline assets, whether for integrity verification, troubleshooting, or pre-intervention diagnostics—without intrusive access or production interruption.
By revealing internal conditions that cannot be externally observed, Scansolution diagnostics eliminate guesswork and support safer operational decisions.
Accurate diagnostic data ensures interventions are justified, targeted, and cost-effective, reducing unnecessary offshore activities.
Early identification of deposits, ingress, or anomalies helps prevent escalation into structural or flow assurance failures.
All services are non-intrusive and can often be performed while pipelines remain in operation.
Subsea pipelines operate out of sight—but they should not operate without insight.
Scansolution Process Diagnostic Services provide offshore operators with clarity, confidence, and control, transforming hidden subsea risks into measurable, actionable data.
By integrating advanced non-intrusive diagnostics into subsea integrity strategies, operators can protect production, enhance safety, and optimise lifecycle costs—without disruption.

Subsea pipeline process diagnostics refers to non-intrusive inspection techniques used to assess the internal condition and integrity of subsea pipelines without cutting, depressurising, or interrupting production. These diagnostics identify deposits, blockages, internal anomalies, and annulus integrity issues that are not visible through external inspection alone.
Scansolution uses radiation-based non-intrusive scanning technologies deployed externally—often via ROVs—to evaluate internal pipeline conditions. This approach allows inspections to be performed while the pipeline remains live, eliminating production downtime.
Scansolution diagnostics can identify and assess:
The scans also indicate deposit location and distribution, supporting targeted pigging or chemical cleaning strategies.
Yes. Scansolution’s scanning techniques can accurately locate stuck pigs or isolation tools within subsea pipelines—even if no tracking device or radioisotope tag was installed. This enables operators to:
Pipe-in-Pipe annulus integrity inspection determines whether water has entered the annular space between the inner and outer pipes of insulated subsea pipelines. Water ingress can significantly reduce thermal efficiency and increase corrosion risk.
Scansolution diagnostics can detect annulus flooding and identify leak locations without intrusive intervention.
Conventional subsea inspection focuses on external visual condition, such as coating damage or marine growth.
Scansolution process diagnostics go further by revealing internal conditions and hidden integrity threats, including:
Together, both approaches provide a complete integrity picture.
Yes. Scansolution diagnostic systems are designed for ROV-assisted deployment, enabling rapid inspection as part of routine subsea campaigns. No marine growth removal is required, and results are available in near real time.
Typical use cases include:
Key benefits include:
Scansolution diagnostics provide high-resolution, repeatable measurements that allow anomalies to be identified, quantified, and analysed during inspection. This accuracy supports engineering-grade decision making, not just screening.
Yes. By identifying hidden internal issues early, subsea pipeline diagnostics help operators prevent escalation into failures, reducing the likelihood of unplanned shutdowns, emergency repairs, and production losses.
Operators can engage Scansolution for:
Early engagement ensures diagnostics are aligned with operational objectives and risk priorities.
