Wind Energy – Cable Installation
Nexans has been awarded a contract worth around 100 million euros by RTE to supply and install 47 km of offshore and 18 km of onshore power export cable for the wind farm located in the English Channel, more than 15.5 km from Le Tréport and 17 km from Dieppe.
With a capacity of 496 MW, the wind farm is expected to produce an average of 2,000 GWh per year, which represents the annual electricity consumption of approximately 850,000 people, or about two-thirds of the population of Seine-Maritime or more than the entire population of the Somme.
Developed by the consortium “Éoliennes en Mer Dieppe Le Tréport”, this is one of the largest commercial offshore wind projects in France.
For the subsea section, Nexans will supply two 23.5 km lengths of 225 kV three-core cable. Featuring innovative new technology, the cable has hybrid armoring and incorporates a fiber optic element to remotely monitor the health of the link and transmit information between the offshore wind farm and the onshore base. The cables will be laid by the CS Skagerrak, one of the Group’s two cable laying vessels along with the newly constructed Aurora.
The onshore link will consist of 18 km of 225 kV single-core cable, similar to that supplied to RTE by Nexans under the current framework contract for onshore cables. Nexans will also be in charge of the cable burial and protection for the onshore section.
The awarded contract includes business continuity services (inspection, maintenance, repair) for the entire project.
