NKT Completes Worlds Longest Power from Shore Cable

NKT has completed the power from shore cable system for Equinor’s Martin Linge oil and gas field in Norway.

The cable system solution from NKT plays a key part in making the field more carbon-efficient as is it powered from shore by the 163 kilometers long 145 kV high-voltage alternate current (HVAC) power cable. The project has been executed on behalf of Subsea 7.

“We are happy to continue the good collaboration with Subsea 7 and Equinor and to be supporting their focus on driving sustainable offshore operations with our extensive experience in turnkey solutions for the oil and gas sector. It is a great achievement for NKT having installed the world’s longest HVAC submarine cable solution and we once again demonstrate that we have the inhouse expertise to design, develop and install solutions in very demanding and complex environments,” said Andreas Berthou, executive vice president and head of HV Solutions at NKT.

NKT has designed, engineered, manufactured and installed the cable order comprising the 145 kV three-core XLPE HVAC submarine cable including fiber optic links with a 55 MW capacity.

Furthermore, a 3,5 km long, 17,5 kV infield cable was installed – including 500 meters of dynamic cable.

The power from shore solution from NKT will help Equinor save 200,000 tonnes CO2 annually once the field is in operation as the activities of Martin Linge will be powered from the onshore power grid instead of onsite generators.
