Nexans to provide €100m of cables for the London Array offshore wind farm

Cable provider Nexans will design, manufacture and supply the high voltage (HV) subsea power export cables for the London Array offshore wind farm under a contract worth around €100 million.

The subsea power export cable contract for the offshore wind farm comprises the design, manufacture and supply of four 150 kV XLPE submarine power cables to be laid in parallel, each 53 to 54 km in length.

Nexans will deliver two of the cables in 2011, and two in 2012, all being delivered in single continuous lengths from Nexans’ factory in Halden, Norway.

The cables for the London Array offshore wind farm will incorporate fibre optic elements manufactured at the Nexans factory in Rognan, Norway. In addition, the contract also includes the cable accessories such as repair joints and terminations.

The London Array offshore wind farm is being installed on a 233 km2 site located around 20 km off the UK coast, in the Thames Estuary. Construction is taking place in two phases: the first phase of 630 MW, consisting of 175 turbines, is expected to be completed and generating in 2012; the future second phase will add capacity to bring the total to 1 GW.

Nexans says its share of the offshore wind farm market has tripled in size over the last four years.
