The project
The East Anglia THREE need reliable high-voltage power links.
The project comprises of an offshore windfarm of 305km2 approximately 69 km from the Suffolk coast and an onshore cable route to transport energy to a convertor station in Bramford.
The project is seen as a centerpiece of UK´s ambition of having 50 GW offshore wind in operation by 2030. The offshore windfarm could power the equvilent of 1.3 millon homes.
As a complete supplier of the cable systems, we are responsible for cable designs, accessory designs, engineering, manufacturing, laying and installation of the cables. The onshore cable will be installed in a pre layed ducted system, including HDDs.
The solution
NKT manufacture all cable systems needed and install them using our cable-laying vessel NKT Victoria.
The high-voltage cables will be produced in our state-of-the-art factory in Karlskrona, Sweden, which operates on 100 % renewable electricity and thereby lowering the carbon footprint of the production. The manufacturing will result in a 320 kV HVDC export cable system of 2 x 147 km offshore cable and 2 x 37 km of onshore cables.
For the cable-laying we will use our upgraded vessel, NKT Victoria, which is one of the industry’s most advanced purpose-built vessels.
The fact that we were chosen for East Anlgia THREE underlines our proven ability and know-how to handle very large complete projects. When fully commissioned, the large wind farm will have an installed capacity of 1.4 GW.
East Anglia THREE could power up to 1.3 million homes
