JDR, a leading supplier of subsea power cables and umbilicals to the global offshore energy industry, has been selected by WindPlus as the preferred cable supplier for the Windfloat Atlantic 25 MW floating wind farm.

The project – located off the coast of Viana de Castelo, Northern Portugal – will see the industry’s first application of dynamic cables operating at 66 kV. The scope of supply includes the design and manufacture of array cables to suit V164 floating turbines. The floating wind turbines will be connected via a network of inter-array cables to one export cable.

To support the project, JDR has designed an easy to install, dynamic cable break away system, which protects the floating platform in the unlikely event of a mooring line failure. Under extreme load conditions, the break away system disengages the cable hardware at the top and bottom of the I-tube and allows the cable to drop to the sea floor, preventing it from exerting excessive tensions on the floating structure in case the platform floats off position. JDR’s proposal also includes HV termination and testing.

James Young, Chief Technology Officer at JDR comments: “We are extremely proud to be selected by WindPlus as the preferred cable supplier for the Windfloat Atlantic project. JDR has an extensive track record in the design and supply of dynamic products to the oil and gas industry. This experience was essential in designing and optimising the cable configuration and accessories to meet the needs of this floating offshore wind project.”

JDR was recently awarded the world’s first large-scale commercial 66kV project, for the East Anglia One wind farm, in the UK.
