New TSC Subsea scanning tool targets tight access inspections

16th August 2021

TSC Subsea, UK, reports the launch of a scanning tool that can be deployed on remotely operated vehicles to carry out tight access field joint inspection through difficult to penetrate pipeline coating.


The ARTEMIS vCompact is a smaller, more flexible and lightweight version of the standard ARTEMIS developed specifically for the tight access inspections of pipelines and structures.


It was built to meet the requirements of a project for Beach Energy in Australia’s Bass Strait to carry out wall thickness inspection on the 20-inch (51-centimetre) Otway pipeline near the Thylacine A platform.


The location of the pipeline joints required remote inspection within a very narrow field joint section, so TSC developed ARTEMIS vCompact as a solution.

Its design incorporates the company’s Acoustic Resonance Technology (ART) that penetrates and inspects through thick subsea coating with lightweight, high-precision three-axis scanning to produce high accuracy wall thickness measurements and corrosion mapping, according to TSC.


Magnetic feet fix the scanner firmly in position and the ROV then detaches and stands off. The tooling utilises 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, explained TSC.
