NKT, one of SSEN Transmission’s key strategic suppliers for the delivery of our Pathway to 2030 investment programme, has announced a major investment in new subsea cable protection technology with the development of the NKT T3600, the world’s most powerful subsea trencher.

The new trencher strengthens NKT’s end‑to‑end cable installation capabilities, supporting the delivery of critical offshore infrastructure required for the transition to renewable energy. Designed to bury subsea power cables up to 5.5 metres below the seabed, the T3600 provides deeper, more resilient protection in increasingly challenging marine environments. 

By engaging local contractors, NKT is helping to reinforce the sustainable supply chain approach shared across SSEN Transmission’s programme of works. 

Darren Fennell, Executive Vice President and Head of HV Solutions at NKT, said:

“Protecting power cables is more important than ever, and 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.” 

The trencher is expected to be commercially operational by 2027.
