New magnetic crawler solution developed for remote subsea inspection - the ACFM® MagCrawler

Following a recent TSC offshore campaign inspecting subsea structures in the Norwegian sector of the North Sea, a new development has evolved in the arena of subsea inspection - the ACFM® MagCrawler. This unique specialised solution enables accurate inspection of subsea welds where access to areas can be difficult or costly to reach with divers. Using the ACFM® MagCrawler Operators can follow complex weld geometries, whilst being able to adapt to the full range of geometries that is typically found in the oil and gas sector.

Operable at depths of up to 150m, the ACFM® MagCrawler can be deployed by ROV and is magnetically attached to the inspection surface, which avoids the need for the ROV to hold station accurately for long periods. Two rubber caterpillar tracks provide the traction enabling the accurate steering of the ACFM® MagCrawler across the surface and using motorised mechanisms the probe can be deployed accurately over the weld to be inspected.

Adjustments of probe position can be made in both parallel and transverse directions, which allows full coverage of the area to be inspected. A 360o degree rotation head means flange welds can be inspected with full coverage of the weld and heat affected zone. The probe is held in contact with the inspection surface using passive compliance, so that the probe is aligned correctly at all times.

The ACFM® MagCrawler can manoeuvre easily on flat surfaces or diameters over 30 inches (760mm) and is now field proven delivering particularly high inspection performance with a capability to detect and size defects as small as 15mm long by 1mm deep in welds, even when inspected through a protective coating.

About TSC Inspection Systems
TSC Inspection Systems provides Non-Destructive Testing (NDT) service, rental and product solutions founded on their unique and patented Alternating Current Field Measurement (ACFM®) Technology. The ACFM technique detects surface-breaking cracks in metallic structures and components, without the need to remove protected coatings, therefore minimizing downtime for critical operations. TSC Inspection Systems was established in 1984, as a spin-off from University College London, by a team of Professors and Lecturers who were recognised leaders in the fields of NDT, robotics and fracture mechanics. ACFM® was developed with support from BP, BG, Conoco and Shell, who were keen to dramatically improve the reliability of underwater inspection, reduce the reliance on the operator and provide auditable inspection records.
TSC offers clients a wide range of support in the execution of inspection programs around the world including Inspection Services, Equipment Rental, Product Sales and Technical Support. For further information please visit the TSC Inspection Systems website www.tscis.com
