Contactless Magnetometric Inspection

We offer Contactless Magnetometric Inspection technology for integrity assessment of non-piggable rigid subsea pipelines, applied via Remotely Operated Vehicles (ROVs) and without interference with operations.

This solution enables the identification of critical stress zones and structural damage, supporting safe and well-informed technical decisions throughout the asset life cycle.

Main applications and capabilities include:

• Contactless subsea inspection with no production shutdown;
• Operation at depths of up to 500 meters, with technical feasibility for ultra-deepwater applications up to 2,000 meters;
• Detection of stress and strain states, cracks, mechanical damage, and fatigue-related corrosion;
• Identification of metal loss, repairs, free spans, deflections, and geometric deviations.

Contactless inspection delivers decisive operational benefits:

• Elimination of PIGs, internal cleaning, and physical interventions;
• High productivity in ROV-based inspection campaigns;
• Reduction of subsea excavations, inspections, and operational costs;
• Objective prioritization of NDT (Non-Destructive Testing), repairs, and interventions.

Our services include the following differentiators:

• Processed magnetograms with georeferenced anomalies;
• Severity classification (Priority 1, 2, and 3);
• Technical recommendations integrated with integrity engineering;
• A solid basis for Fitness For Service (FFS), Risk-Based Inspection (RBI), and inspection planning.
