Set some 19km / 12 miles off the UK’s Kent and Sussex coast in the outer Thames Estuary, the first phase of the London Array Offshore Windfarm comprises 175 wind turbines and 2 offshore substations. The wind farm, to be installed in water depths of up to 23m / 75ft, will be connected by subsea export cables to an onshore substation on the North Kent coast.

The scope awarded to JDR includes the engineering, design and manufacture of over 200 km of 33kV subsea array cables complete with proprietary hang-off and termination systems providing the essential links between individual turbine generators and the offshore substations.

JDR’s strategically located quayside facility at Hartlepool will deliver these cables throughout 2010 and 2011. JDR was awarded the contract by the project consortium of DONG Energy, E.ON and Masdar for the supply of array cables and termination systems for the London Array project, one of the world’s largest offshore wind farms.


JDR’s dedication to the highest levels of quality and continuous improvement, developed over many years of providing subsea power cables for deepwater oil and gas projects is fully aligned with the needs of offshore wind farm operators.

London Array project teams will employ JDR’s proprietary hang-off and termination system; specifically designed for flexibility and reliability to minimise installation costs.
