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

JDR has signed a contract with Siem Offshore Contractors GmbH for the Nordsee One offshore wind farm, currently being developed by RWE Innogy GmbH and forming part of Germany’s largest offshore wind farm cluster.

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.”
