ART vCaliper™
The ART vCaliper™ is a non-intrusive, lightweight, remotely-deployed advance inspection system especially used to obtain pipe ovality, dent measurement as well as high-resolution wall thickness measurements for areas with confined space or tight assess using TSC Subsea’s field proven Acoustic Resonance Technology (ART).
ART vCaliper™
The ART vCaliper™ was designed, developed and built by TSC Subsea’s team of engineers as a bespoke tool to address challenges during a subsea tie back project. The requirement was to inspect the hot tapping location to check for potential ovality and metal loss issues which had limited access for the tool.
The ART vCaliper™ has since proven to be effective for a wide array of uses, particularly when accurate measurements are needed for critical subsea structures with tight access. Common applications include pipeline hot tapping, dent measurement, and sizing for repair clamps, pipelines and other tubular structures, and jackets.
ART’s ability to provide high accuracy pipe ovality measurements as well as high resolution wall thickness through almost any thick subsea coating, results in major cost savings by eliminating the time and effort that would be required for coating removal.
Deployment
The tool features two transducers 180°apart, that collect data simultaneously with a minimum collection of 3 readings for ovality.
The current design scope caters for inspection from 6 – 20” and it can be easily engineered to any diameters required.
The ART vCaliper™ was deployed in the Gulf of Mexico along with MagCrawler that uses ACFM® technology to conduct a combined caliper, wall thickness and weld inspection in a single campaign.

ART vCaliper™ Features and Benefits
Remotely-deployed system with easy interface to all common ROVs, eliminating personnel risk
Light weight and robust design to access tight areas
Provides accurate ovality measurements for dent assessment or repair as well as direct quantitative wall thickness measurements with highly accurate depth sizing (± 0.2mm)
Unique design requires limited dredging around the pipe for access and full coverage
Performs a full circumferential scan efficiently by just moving the tool 180o
High tolerant to soft marine growth and requires limited surface preparation such as HP jetting and brushing
Flexible design enables inspection from 6”-20” and above, with minimal adjustment via a single tool
Capable of deep-water inspection to a depth of 3000m or 300bars

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.
