LITTLEPORT, UK -- A consortium comprising DONG Energy, E.ON, and Masdar has awarded JDR Cable Systems a contract to supply subsea power array cables for the first phase of the London Array offshore wind farm.
The first phase of development, consisting of 175 wind turbines and two offshore substations, will be installed in water depths of up to 23 m (75 ft) approximately 20 km (12 mi) from the Kent and Essex coasts in the outer Thames Estuary. Subsea export cables will connect the wind farm to an onshore substation at Cleve Hill, on the North Kent coast. From the substation, the electricity will be fed into the existing 400-kV transmission network.
The scope awarded to JDR includes engineering, design, and manufacture of over 200 km (124 mi) of 33-kV array cables including proprietary hang-off and termination systems that will link individual wind turbine generators, wind turbine generator arrays, and offshore substations. The cables will be produced in 2010 and 2011.
“JDR has made significant investments over the last three years to address the growing and vital renewable energy initiatives taking hold in the UK and other parts of the world, says Pat Herbert, group CEO, JDR Cable Systems (Holdings) Ltd. “Our plant in Hartlepool was carefully chosen to be located in the heart of the UK offshore community to best serve their ambitious projects yet optimally service all of Northern Europe and other geographies around the world.”
When complete, the first phase of London Array will be among the world’s largest offshore wind farms, delivering up to 630MW, according to JDR. The company estimates that this is enough power for approximately 470,000 homes.
