New Partnership for Robotic ILI Sensor

Integrated (Qi2) have recently executed an agreement to integrate and deploy advanced sensor technology using Robotic In-Line Inspection (R-ILI) devices. Qi2 is a leader in the development of intellectual property and technology solutions with a focus on advanced non-contact measurement systems and sensor solutions. Qi2’s experience includes technology applications in laser profilometry, electromagnetic acoustic transducers (EMAT), piezo-based ultrasonics, microelectronics, computational measurement of complex geometries, and novel materials development. Through the integration of SI’s patented SIPEC™ dynamic Pulsed Eddy Current (PEC) technology and Qi2’s EMAT sensor technology with a wide-range of state-ofthe-art robotic platforms, the team will deliver one of the most  comprehensive and capable suites of remote inspections solutions available in the industry. For our clients, this means inspection of previously inaccessible areas, less cleaning prior to inspections, improved inspection coverage, and shorter inspection evolutions.

Many pipelines, segments, and components are not conducive to conventional In-Line Inspection (ILI) or current R-ILI solutions and direct examination of the component using traditional NDE methodologies is prohibitive. For example, tight radius bends, short runs, dimensional changes, low-flow pipelines, single-point access, unbarred tees and internally lined piping can pose a challenge for conventional tools and/or may not be cost effective. The combination of a dynamic PEC metal loss sensor, together with a delivery solution that can navigate “inaccessible” locations, can increase safety by allowing the inspection of a new class of components previously un-inspectable or deemed “extremely costly” to inspect. This methodology can be used in hazardous liquid, natural gas, petrochemical and the water industries and can be applied to any ferrous metal that is susceptible to corrosion degradation.

The SIPEC technology is useful for inspecting components for wall loss through internal liners or in situations where relatively large sensor liftoff may be necessary, such as crude and refined products pipeline that may not be thoroughly cleaned. The dynamic SIPEC technology has several advantages over other existing PEC technologies including improved spatial resolution; improved signal-to-noise ratio; the ability to distinguish between internal and external metal loss; and most importantly, the ability to rapidly acquire data while in motion (dynamic data acquisition).

SI is proud to be teaming with Qi2 to bring this new technology to our clients. We will be releasing more
detailed information and specifications about the technology in the near future and look forward to the first field applications in 2019.
