ART – Acoustic Resonance Technology

The advantages of acoustic resonance technology (ART) have long been recognised in the subsea inspection marketplace. The technology—with its coating penetration and accuracy capabilities for through-wall inspection of pressure holding equipment—is well suited to detect mediums. TSC Subsea’s ART is deployed remotely via our ARTEMIS™ system to provide unique external inspection of subsea assets, including rigid and flexible pipelines, flowlines and risers.

ACFM – Alternating Current Field Measurement

For 30 years, alternating current field measurement (ACFM) electromagnetic inspection technology has been the method of choice for detecting and sizing subsea surface-breaking cracks. Recognized and approved by many certification bodies, including DNV, ABS and Lloyds, the technique has been used successfully to supersede traditional non-computerized and more user-dependent methods, such as magnetic particle inspection (MPI).

PEC – Pulsed Eddy Current

Corrosion under insulation is possibly the greatest unresolved asset integrity problem in the industry. Adding a subsea environment to that increases the challenge ten-fold. Current methods for measuring wall thickness over insulation (liftoff) without removing it all have severe limitations. TSC Subsea’s exclusive ROV-deployed subsea Eddyfi Lyft® and high-resolution array probes provide a high-performance solution that reinvents pulsed eddy current (PEC).
