Helix, NKT partner to deploy 'world's most powerful' subsea trencher

Helix Robotics, the UK robotics division of Helix Energy Solutions, has entered into a long-term cooperation and frame agreement with NKT A/S (NKT), a designer, manufacturer and installer of power cable solutions, to serve as a key partner for the new T3600, designed to be the world’s most powerful subsea trencher. 

The agreement includes installation, offshore operations, project engineering, and maintenance of the T3600 subsea trencher, which will be deployed on a Helix-provided support vessel. The Helix support vessel will be equipped with the T-1200 Jet Trencher, two work-class remotely operated vehicles (ROVs), and a full survey spread, including personnel, to support NKT’s offshore cable burial and construction activities. The agreement includes an initial commitment of 800 days of vessel operations over four years, commencing in 2027, with options for extension.

“We are thrilled to execute another long-term agreement with NKT, this time for the new T3600 trencher and T-1200 trenching spread,” said Scotty Sparks, Executive Vice President and Chief Operating Officer at Helix. “By combining Helix’s advanced robotics, world-class T-1200 trenching spread, and offshore expertise with NKT’s experience of pioneering sustainable power cable solutions, we are poised to enhance the reliability and efficiency of critical energy infrastructure.”
