FPSO Pressure Vessel Inspection Using MultiPhonon

This video presents a real-world pressure vessel inspection performed on an FPSO using MultiPhonon non-intrusive, in-service inspection technology.

The inspection was carried out under normal operating conditions, without depressurization, shutdown, or internal access. By applying Volumetric Mode inspection, MultiPhonon enabled full assessment of the pressure vessel — including critical internal areas — while the asset remained fully operational.

The video demonstrates how MultiPhonon detects active defects, such as corrosion, wall loss, cracks, and stress-related anomalies, by analyzing phonon behavior within the material’s crystal lattice. This approach provides complete volumetric coverage, accurate defect localization, and high-confidence results without the risks associated with confined-space entry or production interruption.

Completed within a short execution time and with a small inspection team, the project highlights the efficiency, safety, and reliability of MultiPhonon for offshore pressure vessel integrity management. The results supported informed decision-making while significantly reducing downtime, cost, and operational risk.
