Test Results Prove Revolutionary New Cable Technology

World-leading subsea robotics design and manufacturing specialists, Soil Machine Dynamics (SMD) has partnered with Dutch subsea contractor N-SEA to successfully prove ground-breaking new subsea technology that could change the future of cable construction.

ARTEMIS Survey is the new high-frequency electromagnetic cable and pipeline survey system tested in live environments by N-SEA and SMD in the North Sea in November 2020. During the offshore sea trial on a buried live cable, the data produced by ARTEMIS Survey when compared with pre-existing data successfully proved the location of this power cable, buried to a depth of 2m below the seabed and at an overall distance of 4m from the cable, in line with offshore survey standards.

This is a significant step-change in the detection performance for unpowered and abandoned cables, a capability which will revolutionize cable construction and maintenance activities carried out during low wind productivity or when cable failures have occurred.

Commenting on the ground-breaking technology, Stephen Wilson, Strategic Business Development Manager from SMD, said, “The live trials were the culmination of a two-year journey to develop this new equipment. Along with our partner Optimal Ranging, the research and development team has focused on applying the unique nature of high-frequency electromagnetic fields to produce an easy-to-use, operationally ready survey system that can be fitted to any ROV. The fact it works on dead or faulty cables – something that has never been achieved before – has huge implications for the future of the cabling industry. We are very excited to see where ARTEMIS leads.”

SMD has worked with several early-adopter offshore survey teams to test and improve the system and has now agreed on an ongoing development partnership with N-SEA to test ARTEMIS Survey across its full range of power, telecom cables and pipeline applications.

Paul van Waalwijk, Managing Director from N-SEA, said, “We were an early adopter of the ARTEMIS technology and are proud to have been a part of this journey so fa. We completed a trial on a live cable and are excited to continue the exploration, together with SMD and Optimal Ranging. The detection of a buried cable in both horizontal and vertical directions has been one of the biggest challenges in the last decade. This system will disrupt the subsea cable and pipeline survey market.”

According to Pradeep Pandey, CEO of Optimal Ranging, “We have a proven record of innovating and delivering sensor systems and software based on modeling and measuring electromagnetic fields. SMD and Optimal Range share a common vision and goal of providing solutions to challenging problems relate to the offshore utility grid. The breakthrough performance of ARTEMIS is a result of our close cooperation and diligence. We look forward to working together to continue to develop and deliver solutions”

SMD and N-SEA are now seeking asset owners and contractors that are interested in using this new technology.
