TSC Subsea’s ARTEMIS vCompact – a solution to being in a tight spot

the capability of ART to produce high resolution data through anti-corrosion coating without having to remove that coating, means that it provides a high- specification solution to challenges such as these. “Having proven its credentials, there is huge potential for its use in and around subsea structures and pipelines where accurate remaining wall thickness meas- urements are critical for safe operations.” The location of the pipeline joints required the inspection to be conducted remotely within a very narrow field joint section which was too confined for the standard ARTEMIS. The solution, in the form of the ARTEMIS vCompact, was developed. The design incorporates TSC Subsea’s Acoustic Resonance Technology (ART). ART is a 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. Strong magnetic feet fix the scanner firmly in position. The ROV then detaches and stands off, negating the need for it to hold station accurately for long periods of time. 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

TSC Subsea, a developer of advanced subsea inspection solutions for challeng- ing situations, has designed a new ROV- deployed automated scanning tool that addresses the issue of carrying out tight access field joint inspection through difficult to penetrate pipeline coating. The ARTEMIS ® vCompact, a smaller, lightweight, more-flexible version of the standard ARTEMIS, was designed, developed and built by TSC Subsea’s engineers to work in tandem with inspection class ROV for the remote inspection of pipelines and structures. It was designed and built in a turnaround time of less than six weeks to meet the precise requirements of a project for Beach Energy in Australia’s Bass Strait, to carry out wall thickness inspection on the 20" Otway pipeline near the Thylacine A platform. “The ARTEMIS vCompact successfully completed its operations for Beach Energy with flying colours, with all inspections being performed within two days,” said Stephan Freychet, senior project manager. “All the data from the remote inspection was analysed remotely by a team in Norway. “This project demonstrated the potential of the ARTEMIS vCompact and the industry-leading capability of ART. It can be deployed in a number of applications where size and agility are crucial in overcoming the problems of tight access. This, combined with A laser welded fin tube, which is used for furnaced and industrial boilers has been released in China for the first time. The advantage of the new fin tube is that the contact thermal resistance is almost zero. Compared with high frequency welding, it has the characteristics of a high finned ratio and light weight and compact assembled heat exchanger volume, which is more energy-efficient and better for the environment. There are many types of fin tubes, mainly high frequency welding finned tubes. Although compared with embedded and braised methods, they are more advanced in product quality and production automation.

Jonathan Bancroft, global sales manager, said: “I’m immensely proud of the new ARTEMIS vCompact solution that the TSC team developed in record time. Our client had a problem with no solution, and in just six weeks our engineers designed, built and tested the ARTEMIS vCompact to address the market gap. This new solution is a great addition to our diverless inspection portfolio and demonstrates TSC Subsea’s commitment to innovate through technology.’’ TSC Subsea www.tscsubsea.com Laser welded fin tube innovation released in China

which has a number of big advantages: the thickness of base pipe can be 0.8 to 1.5mm, and the thickness of fins can be 0.3 to 1mm. Compared with other processes, material cost is greatly improved; the penetration rate is also higher, which can prevent the corrosion of gap, prolong the service life and reduce the heat transfer resistance; the material limit is broken and different materials can be used for processing; it is easy to complete deep fabrication – coil and bend can be directly carried out; the welding heat affected area is small and the metallographic change is small, which makes it possible to process the small diameter fin tube.

However, there are many shortcomings in heat exchange efficiency and dust prevention. Laser welded finned tubes are a more technologically advanced product,
