Abstract
Capacitive Imaging (CI) technique, which employs fringing electric field between coplanar electrodes, has demonstrated its capabilities of non-destructively detecting both surface and hidden defect in dielectric materials and characterizing conducting surface through a relatively thick insulation layer. This paper aims to provide an insight into the CI technique and demonstrate its feasibility on solving some challenging inspection problems (i.e. corrosion under insulation and composite materials /structures) in the oil and gas structures. The CI concept is explained, and the experiments to investigate the usefulness of the capacitive technique for composite materials inspection and detecting corrosion under insulation are presented.
