NKT is reinforcing its commitment to securing critical power cable infrastructure by investing in the advanced powerful subsea trencher NKT T3600. This state-of-the-art equipment will enhance the protection of subsea cables, ensuring secure energy transmission and supporting the transition to renewable energy.
To meet the high demand for high-voltage power cables needed for renewable energy, NKT is investing in manufacturing and installation capabilities, including the NKT Eleonora, a new cable lay vessel that can lay heavier and longer-length power cables. As a natural progression, NKT is now also investing in enhanced cable protection technology with the construction of the world’s most powerful subsea trencher, delivering 3,600 horsepower to bury cables to depths of up to 5.5 meters below the seabed. This investment further strengthens NKT’s complete cable solutions for installing power cables at deeper depths with minimal risk.
“Protecting power cables is more important than ever due to the increased risk of sabotage and high activity at sea. This trencher will be best in class, ensuring reliable deep-burial protection of power cables in even the most challenging soil conditions. With this investment, we also support the local economy by engaging UK companies in the design and development of the trencher,” says Darren Fennell, Executive Vice President and Head of HV Solutions at NKT.
In line with NKT’s goal to leave a positive long-term legacy in all areas where it conducts business, this investment will support local employment and contribute to the long-term viability of UK-based contractors. This is demonstrated by the award of a substantial contract to OSBIT Ltd, a UK-based original equipment supplier responsible for designing and constructing the trencher, as well as the Launch & Recovery System.
NKT’s investment in this subsea trencher not only supports the local UK economy but also improves the security of energy supply through the protection of critical infrastructure. From a biodiversity standpoint, the trencher ensures that cables are buried with minimal impact on the surrounding ecosystem.
