Subsea Inspection Services

TSC Subsea is a technology-enabled inspection vendor that specializes in solving the most challenging subsea NDT inspections anywhere in the world.

What is ACFM?

Alternating current field measurement (ACFM) is an electromagnetic inspection technique that introduces an alternating current into the surface of a component to detect surface-breaking cracks.

What is ART?

Acoustic Resonance Technology (ART) is a patented, ultra-wideband acoustic inspection technology that offers penetration and measurement capabilities exceeding those of existing inspection technologies, providing accurate wall thickness measurement and metal loss detection.

Flexible Riser Inspection

With a cost-effective, non-intrusive inspection method, the ARTEMIS utilizes ART to detect the presence of gas or water medium under layers of coating in a flexible riser.

State of the ART Deployment system

Expert in providing customised solutions for complicated geometry and tight access for clients

TSC Subsea is specialised in advanced subsea inspection methods for challenges where conventional NDT can’t work. With remotely deployable inspection tools we go where divers can’t operate, in hazardous environments, and in restricted locations to inspect welds, pipelines and offshore structures.

Case Studies

External Subsea Inspection of Flexible Risers

TSC Subsea’s Acoustic Resonance Technology (ART) is currently the only third-party validated method of subsea detection of liquid ingress in the annulus of flexible production risers. It is deployed using the ARTEMIS® tool which has a broad application range and can be used on risers and flowlines down to 3000m water depth.
