The MagControl NDT technology allows inspection of pipelines with coatings thickness up to 20 mm and pipe wall thicknesses up to 1 inch to detect internal and external localized or generalized corrosion. The strength of the MagControl electromagnetic technology is its reliable detection sensitivity for localized defects, as well as its high resolution and scanning speed. Rated for a water depth of 2.500m, the MagControl based MagIQ SC200 subsea crawler can be adapted to inspect a wide range of pipe diameters from 6” and up.

PECT

The pulsed eddy current testing technique allows the inspection of thick insulated and concrete weight coated subsea pipelines. The subsea scanning crawler system enables inspection of up to 200mm of insulation or concrete weight coating. The detection capability with PECT technology in particular of internal pipe defects is upfront modelled as depending on size footprint generatable related to the overall coating and the pipe wall thickness.

Ultrasonics

Where the inspection surface allows InnetiQs implements ultrasonic sensors in parallel with the MagControl sensors to enable a parallel combination inspection approach of a highly sensitive electromagnetic technique for localized defect detection and absolute wall thickness scan by the multiple ultrasonic sensors in parallel to the electromagnetic sensor array.

Advanced Ultrasonics for high-resolution scans, e.g. for welds or specific focused inspection areas, C-scan mapping is performed with the FADS track system using special advanced ultrasonic sensors. The crawler’s ability to crawl and deep sea with up to 2,500m and its independent axial and circumferential orientation enables the crawler to operate independently between the splash zone and the deep sea.
