By November 2010 the partial replacement of KONTEK's submarine cable system was complete. Energinet.dk had contracted Nexans Norway to install two new 600 MW, 400 kV mass-impregnated HVDC submarine cables — approximately 6.9 km across Storstrømmen between Zealand and Falster, and 43.6 km across the Baltic Sea between Denmark and Germany — replacing the original oil-filled "Old Kontek" subsea cables that had been in service since 1995. JD-Contractor A/S was awarded the follow-on post-burial scope, performing jetting on the soft-sediment sections of the route and after-processing of cables in pre-excavated trenches using the vessels M/S Honte and S/B Victor in Storstrømmen, and M/S Cable One and M/S Vina in the Baltic Sea, all using the diver-operated "Light Jet" system combined with suction units and high-pressure cutting tools. Post-burial was carried out by several vessels during the second half of 2010 and was complete by November 2010, returning the modernised subsea section to service ahead of the wider 2021-2023 onshore replacement programme.
