Contract Details
Description
NKT Cable A/S acted as the sea cable and grid connection contractor for the Middelgrunden offshore wind farm, supplying and installing the 30 kV export cable system linking the wind farm to the onshore grid at Amagerværket in Copenhagen. The grid connection uses two parallel 20 MVA submarine cables laid from the centre of the wind farm to shore over a 3.5 km route, with the cables spaced about 15 metres apart. NKT manufactured the HVAC submarine export cables and used a purpose-built cable-laying vessel to install them, including pulling the cables up through the lower tower sections once the gravity foundations were in place. The work formed part of the main construction campaign in 2000, under contracts signed in December 1999.
