Subsea Pipeline Inspection
Subsea pipeline inspections require the highest level of accuracy to produce high-quality data. Pipeline integrity depends on it. TSC Subsea ARTEMIS® and the ARTEMIS® vCompact, incorporating TSC Subsea’s industry-leading Acoustic Resonance Technology (ART), offer unique solutions for inspecting unpiggable pipes. ART is the only high-resolution technology that penetrates and inspects through thick subsea coating with lightweight, high-precision 3-axis scanning to produce high accuracy wall thickness measurements and corrosion mapping.
In-Service External Subsea Pipeline Inspection
The TSC Subsea ARTEMIS® ART system enables subsea pipeline inspection via ROV without the need for field joint coating removal. This greatly reduces integrity risk and the cost of expensive inspection operations. The ARTEMIS® is compatible with most work-class ROVs and delivers real time data that provides a 2D image of the wall thickness of the inspected area. The inspection can also provide information about coating thickness and identifies whether a loss of wall thickness is on the outside or inside of the inspection area of the pipe.
It has a wide range of applications including through-coating inspections, piggyback solutions and field joint inspections.
Key benefits of TSC Subsea ARTEMIS®, incorporating ART technology, include:
- Remotely deployed by inspection or WROV
- Provides direct quantitative wall thickness measurement with highly accurate depth sizing (± 0.2mm)
- Versatile design for axial and circumferential measurements
- Instant data capture with live topside feed for audit and comparison purposes
- Lightweight with minimal dredging requirements
- Minimal vessel time required
- Enhances life extension of the equipment
ARTEMIS® vCompact
Developed in 2021, the TSC Subsea ARTEMIS® vCompact is a smaller, lightweight, more-flexible version of the standard ARTEMIS®. Incorporating TSC Subsea’s ART technology in its design, it has all the capabilities of ARTEMIS® with some additional features. Its smaller size and more flexible frame makes it the ideal solution for tight access field joint, right access tubular, subsea jumpers, risers and riser guides and hot tapping locations inspection without the need for coating removal. Designed to work in tandem with inspection class ROV for the remote inspection of pipelines and structures, the tooling uses motorised and encoded manipulators which enable the probe to accurately follow the areas to be inspected. Inspection data is transferred to a topside computer and can be analysed from anywhere in the world.
Key additional benefits of TSC Subsea ARTEMIS® vCompact, incorporating ART technology, include:
- Tight access semi-automated precision scanner with ART
- Diameters range 89mm (3″) to 3000mm (118″)
- Dedicated ‘teach and learn’ software to follow complex geometries
- Magnetically attached for efficient deployment

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.
