Stop CUI Blind Spots. Meet MultiPhonon

Meet MultiPhonon: The Future of In-Service Inspection Technology. MultiPhonon is a next-generation, non-intrusive inspection technology designed to transform the way critical industrial assets are inspected — without shutdowns, insulation removal, or operational disruption.

In this video, we introduce how MultiPhonon addresses one of the most critical challenges in asset integrity management: hidden corrosion, including corrosion under insulation (CUI) and corrosion under pipe supports (CUPS).

Why Hidden Corrosion Is a Major Industry Challenge. Corrosion beneath insulation and coatings often remains undetected until it causes leaks, failures, or costly shutdowns. Traditional inspection methods are slow, labor-intensive, and typically require insulation removal, scaffolding, or confined-space entry — increasing risk, cost, and downtime.

MultiPhonon provides a faster, safer, and smarter alternative by enabling inspections in-service and under normal operating conditions.

How MultiPhonon Works.

MultiPhonon uses patented phonon-based inspection technology to detect active defects inside metallic structures. Phonons — vibrational energy packets within a material’s crystal lattice — behave differently when corrosion, cracks, or stress-related damage is present.

By analyzing these changes, MultiPhonon accurately detects:

• Corrosion and wall loss

• Cracks and crack-like defects

• Leaks

• Actively propagating defects

All without requiring physical access to the internal surface.

Applications Across Critical Assets

The video demonstrates real-world applications of MultiPhonon across a wide range of industrial assets, including:

• Pipelines and insulated piping systems

• Offshore and onshore risers

• Pressure vessels and reactors

• Storage tanks (including tank bottoms)

• Complex structures and jackets

Inspections can be performed in Linear, Planar, or Volumetric modes, providing full coverage for assets of varying geometries and sizes.

Key Advantages of MultiPhonon

• Zero downtime — inspections performed during normal operations

• Non-intrusive — no insulation removal except at sensor locations

• Long-range coverage — hundreds of meters from a single sensor position

• High accuracy — high probability of detection (POD > 80%)

• Improved safety — no confined-space entry or work at height

• Cost-efficient — reduced shutdown, manpower, and preparation costs

Proven Technology, Industry Adoption

MultiPhonon has been independently verified and adopted by major operators worldwide. Its performance has been validated through direct comparison with traditional inspection methods, delivering equivalent accuracy with significantly reduced time, risk, and cost.

With demonstrated success across offshore platforms, FPSOs, refineries, and terminals, MultiPhonon is redefining in-service inspection and asset integrity management.
