Nordsee One OWF First to Use JDR’s New Aluminium Core Inter-Array Cable

JDR will provide over 70 kilometres of aluminium core inter-array cable, cable accessories and post-delivery offshore services. The Nordsee One Offshore Wind Farm will be located some 40 kilometers north of the German Juist island and will be set in a water depth of up to 34 metres.

The Nordsee One Offshore Wind Farm will have 54 wind turbines. The project will utilise two JDR designed inter-array cables: a 240mm2 aluminium conductor cable and an 800mm2 aluminium conductor cable. Both cables will be XLPE insulated and type tested to IEC 60502-2 and CIGRE standards. The cables will be designed by JDR’s in-house engineering team and manufactured at JDR’s Hartlepool facility. This specialist facility is alongside a deepwater dock, ideally positioned for load-outs for European offshore wind farm projects.

Alongside the inter-array cables, JDR will supply a range of accessories including cable pulling grips and hang-offs, cable cleats, power core termination connectors and fibre optic splice boxes. To complete the project, JDR’s Global Services will provide field service teams to install the hang-off as well as to route, terminate and test each inter-array cable. JDR’s experience in offshore wind field support is backed by a knowledge base of JDR work commissioning subsea power cables for oil and gas projects.

Paul Gahm, JDR’s EVP Sales and Marketing , commented: “We’re pleased to have won this important contract with Siem Offshore Contractors GmbH for the Nordsee One offshore wind farm; this project is a strategically important development for the European offshore wind market. The cost-efficient aluminium core inter-array cables that have been selected for this project are the latest development in a growing JDR range of products and accessories, designed to support the long-term development of offshore wind energy production.”
