Technology
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).

Deploying dual NDT methods for the inspection of complex welds.
The Challenge TSC Subsea received a request from a major operator, Equinor AS, to evaluate the feasibility of inspecting subsea risers coated with thermally sprayed aluminium (TSA). Specifically, the inspection focused on assessing the fillet weld surrounding an anode...
Inspecting Concrete Weighed Pipes with SPECTA
The Challenge TSC Subsea was contracted by a client to carry out wall thickness assessment of Condensate Export Pipeline (CEP) and Pipeline End Manifold (PLEM) without removing the protective concrete weight coat (CWC). The assessment was required as the client...
Subsea Phased Array (SPA)
TSC Subsea were challenged to investigate sand erosion concerns on subsea structure piping off the coast of Western Australia. The inspection campaign covered multiple assets including Pipeline End Manifold (PLEM), tie in spool and subsea cooling skid in the Halyard Field and a PLEM in the East Spar Field.
