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.

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

Smooth Sailing with ACFM Crack Assessment on Cargo Ship Propellers.
The Archon Gabriel Bulk Carrier was navigating the cold waters of the Gulf of Finland. The harsh sea conditions, laden with sea ice, posed significant navigational challenges and resulted in the ship’s 6-meter diameter bronze propeller suffering ice damage. Given the...
Diverless ACFM Inspection Solution for FPSO Bilge Keel Weld Integrity Assessment.
FPSO operators are increasingly seeking ways to inspect their hulls below the waterline without resorting to drydocking, a costly process that entails significant production loss, rendering it inefficient and logistically challenging. Recognising the benefits of a...
Tethered ILI Robotic Solution for Internal Riser and Pipeline Inspection
The Challenge bp sought a comprehensive, circumferential 360-degree scan of the riser. TSC Subsea provided the solution - a robotic system that could both travel longitudinally along the riser and had the ability to precisely stop and stabilise itself, in order to...
