The MEC-Combi Crawler is a sophisticated self-crawling inspection system that supports the inspection and lifetime assessment of subsea structures ranging in size and complexity such as risers, caisson, pipes, platform legs and flat surfaces like ship hulls.
The MEC-Combi Crawler enables the detection of localised defects and general wall loss in subsea structures while scanning externally. A change out of the curvature adaptation allows the MEC-Combi Crawler to be used for the inspection of smaller diameter pipes and flat surfaces like ship hulls.
The MEC-Combi Crawler is based on the next generation of fast corrosion mapping Magnetic Eddy Current (MEC)
technique which is the further development of the Saturation Low Frequency Eddy Current (SLOFEC™) technique.
With the use of magnetic field controlled high frequency Eddy Current,
the MEC technique offers enhanced inspection capabilities including inspecting through a 35mm fire protective coating.
The MEC-Combi Crawler system combines the fast scanning MEC sensor array system with an Ultrasonic sensor unit to identify localised defects and to provide valuable data on internal and external wall loss. A versatile inspection tool, the MEC-Combi Crawler also enables the incorporation of other supporting inspection techniques such as high resolution Ultrasonic mapping, Pulsed Eddy Current (PEC), laser triangulation system, camera and light system, etc to provide comprehensive inspection data within a single deployment. The MEC-Combi Crawler supports the deployment from the installation by divers as well as via ROV from the support vessel.

Key capabilities of MEC-Combi Crawler:
Together with Innospection's comprehensive reporting software, accurate and reliable inspection results are generated in real time. The advanced colour condition mapping report provides analysis of the internal and external defects in term of size, severity of wall loss and locations of defects and other occurrences.
