Overview

ICR’s accredited Inspection services body uses a cutting-edge non-destructive testing technique designed for inspecting composite repairs applied to metallic components. With validation from the Welding Institute (TWI), Lloyds Register, and UKAS accreditation, the inspection technique has been developed to ensure the condition and integrity of composite repairs. It provides data-driven evidence to support the safe and sustainable life extension of repairs and aging assets. 

Why inspect composites?

As aging assets and composite repairs reach the end of their design life, there is a growing need to revalidate or extend their lifespan. This allows operators to avoid costly replacement options that may lead to asset shutdowns. Regulatory bodies are increasingly focusing on integrity management and condition monitoring of repairs, making the inspection of defined life repairs crucial for ensuring continued safe and reliable operations. 

However, current inspection techniques face limitations in practical deployment in the field and accessing complex geometries with a single technique or product. ICR addresses these challenges, providing a practical solution for inspections and potentially allowing the use of composite repairs in higher-risk locations, subject to risk assessment and engineering validation.

Benefits

Our composite inspection service offers numerous benefits to operators and industries: 

• Ongoing inspection and life extension: Allows for the ongoing inspection and safe extension of defined life repairs, reducing carbon emissions associated with traditional steel replacement. 

• Portability and accessibility: The portable hand-held equipment, along with specifically designed probes, can be used on all system configurations and geometries, including areas with challenging access. The equipment fits in a small peli-case, ensuring easy transportation. 

• Precise detection: ICR’s manually operated modified probes are designed to access all system configurations, detecting anomalies in the composite material, the bond line, and the metallic substrate, providing a comprehensive inspection report. 

• Automated reporting: Additionally, an automated and user-friendly visual inspection report/3D model is provided, enhancing the efficiency of the inspection process. 

 

Capabilities

Our technique excels in detecting anomalies in two main areas of concern: 

• The bond line
• Interlaminar dis-bonds  

Using principles of acoustic inspection methods such as pitch and catch, resonance, and mechanical impedance analysis, the Inspection services body of ICR can detect and size flaws. The scanner provides 3D models and visual representations of the composite repair, allowing for precise dimensions to be used in assessments.  This innovative technique offers clients the confidence to validate and extend the life of repairs based on data-driven assessments.
