REMOTE UWILD INSPECTION
In response to this and other environmental factors, TSC’s Engineering solutions team have developed the ACFM® MagCrawler™. This unit has been designed specifically to enable the ROV deployment of ACFM® Array Probe Technology underwater, and can inspect a wide variety of subsea geometries, including circumferential, fillet and full penetration welds in pipes and plates. Ideal for restricted-access areas, the MagCrawler is rated up to 150m (493ft) and is a robust, magnetic-tracked ROV equipped with cameras. Traction is achieved by two rubber caterpillar tracks that are easily maneuverable on horizontal and vertical planes, as well as inverted surfaces. Probes are mounted onto the crawler with a metal sprung arm for passive compliance with the surface and a 360° rotational head allows full weld coverage. An electronic rotary encoder also is on board to determine the position of the crawler and simultaneously collect distance measurements whilst scanning.
