The subsea cable will be a 150 kV DC cable with an integral return conductor, similar to the cable Nexans delivered for the Moyle Interconnector project in 2001, which links Northern Ireland and Scotland. The fiber-optic cable will be bundled to the power cable during installation. Nexans is carrying out this project on a turnkey basis and will install and also bury the cable. The installation work will take place in 2008 and 2009 using the cable laying ship the C/S Skagerrak. For protection against external damage (such as fishing boat activity), the cable will be buried to a depth of around one meter into the seabed using Nexans' CapJet system.
The power cable will be manufactured at Nexans' factory in Halden, Norway while the fibre-optic cable will be manufactured at Nexans' factory in Rognan, Norway.
Saving natural resources and environmentally friendly
The subsea cables will be taken ashore at Lista, on the coast of Norway, where the beaches are known for their sandy dunes and special fauna, which includes marram grass and lyme grass. There have also been many important archaeological finds in this area. In addition, Lista is very important as a stopping-off point for birds when they are migrating or during the winter. Due to Lista's rich plant and bird life, large parts of the beaches are protected areas. BP has made considerable efforts to ensure that these areas will be protected during the construction work – and Nexans will continue this work.
