NKT has successfully completed the second repair operation this year on the important cable connection BritNed located in the sea north of the Strait of Dover connecting the UK with the Netherlands. For NKT, the repair operation turned into some creative engineering and craftmanship due to the nature of the repair requiring repair and re-configuration of the cable system on the seabed.

- I am very satisfied with the result and that we once again demonstrate how our extensive experience in repair operations and the high degree of flexibility make a difference for our client, says Axel Barnekow Widmark, Executive Vice President and Head of Service at NKT.

For BritNed Development Limited, the owner of the interconnector, the project has also been successful.

- We are very satisfied with the collaboration with NKT and the creativity and craftmanship shown when redesigning an alternative solution for the cable repair route, says Dennis Stufkens, Operations Director at BritNed.

The BritNed interconnector is part of the investments made by the national grid operators National Grid (UK) and TenneT (Germany/Netherlands) to ensure security and diversity of energy supply needed to drive the transition to renewable energy.

NKT is one of the leading companies in the market providing both stand-alone repair operations and customized service packages ensuring the fastest mobilization time in the market. The successful operation was completed in the beginning of June where the BritNed interconnector also was back in operation.
