Specialist Non Destructive Testing

   

Non destructive testing (NDT) techniques have been established within modern industry for a significant period of time. Ranging from the relatively low end to more advance technology, these methodologies and techniques have formed a cornerstone of inspection and verification to process plant and manufacturing. NDT has traditionally been applied by manual intervention or in a static and controlled environment for high volume repetition. With the upsurge in offshore Oil and gas, gaps have appeared in the market place where traditional inspection or NDT methods would not be readily practical.

This was typical of areas where the physical location of the process plant prevented easy access or if situated underwater or subsea. Iicorr took a unique and innovative approach to bridging the gap between the traditional and new frontier working environments. The advancement of new technology provided the opportunity to cost effectively develop versatile and innovative technical solutions for providing inspection data. Iicorr combined this engineering expertise with practical know how to enable and package a managed service for it's client base that has yet to be fully rivalled.

Why use iicorr

Iicorr uniqueness stems from an engineering and technical foundation that aims to provide the optimum solution for the end client. Each work task or job is treated as an individual project that assesses the specific inspection requirements and what is required to achieve that. The basic principles of inspection utilise ultrasonic and eddy current technology as the building blocks of the systems.

  • Ultrasonic testing for thickness and flaw detection in pipe, tubulars and welds.
  • Eddy current testing for surface breaking crack detection.

The concept of remotely deployed NDT has been possible by development of robotic scanning tools that manipulate the inspection probe(s) over the surface under test. These scanning tools are connected by multicore umbilical cable to a PC based workstation that allows full control of the scanning tool and real time display of the inspection data. There is a full range of scanning tools available that cover a wide range of pipe diameters and geometries both for internal and external inspection. Deployment of the scanning tools can be by simple gravity, or manual fed systems. For extended reach capability crawler or tracked vehicle insertion has been utilised to pull the system along pipelines or other tubular systems.
