JDR SELECTED AS PREFERRED CABLE SUPPLIER FOR WINDFLOAT ATLANTIC PROJECT
Project will see world’s first application of innovative 66kV technology to dynamic cabling for floating offshore wind.
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 (WFA) 25MW floating wind farm.
MAATS Tech Limited, the marine engineering consultancy specialising in bespoke carousel and deck handling systems, is celebrating the successful completion of the NKT Victoria, a world-class cable lay vessel (CLV). The ship was delivered by the Kleven Shipyard to NKT, the global provider of turnkey AC/DC cables for the sustainable energy and energy export industries, and recently achieved the Nor-Shipping Ship of the Year award.
The 26-month project saw MAATS Tech manage the design, fabrication, delivery, installation and commissioning of the highly technical cable lay mission equipment to dNV certification. The specialist kit included two four-track 45-tonne tensioners, a 7000te on deck carousel, a 4500te underdeck carousel, loading arms, three three-tonne tensioners, chute assemblies and roller pathways, enabling the vessel to load or unload three products at synchronised speed.
William Gibby, Technical Director at MAATS Tech, says: “This gold standard project has delivered one of the world’s most advanced vessels. We worked closely with NKT, Salt Ship Design and Kleven
Shipyard to introduce bespoke equipment to meet the specific project requirements and were able to achieve full DNV certification in the process. Overseeing this cutting-edge project has been an honour. We’re extremely excited for the future of the cable laying industry.”
The contract was awarded in March 2015, and the project began in the same month. MAATS Tech was selected due to its advanced technical capabilities, the digital visualisations it was able to provide in the tendering process, and its unique end-to- end client support.
MAATS Tech’s specialist equipment was mainly manufactured in the UK, with a large team of core suppliers and subcontractors. The company oversaw the development and delivery of the equipment to meet the schedule and also attended a series of trials before the ship was christened the NKT Victoria in karlskrona, Sweden in May 2017. MAATS Tech employs 42 people.
The NKT Victoria is currently on route to its first operation in the North Sea and as part of MAATS Tech’s ongoing after- contract support, the company will be on stand-by to offer technical support and advice.
The project – located off the coast of Viana de Castelo, Northern Portugal – will see the industry’s first application of dynamic cables operating at 66kV. 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 a unique, easy to install, dynamic cable break away system, which protects the floating platform in the unlikely event of a mooring line failure. 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.”
WFA brings together two pioneering developments in array cables: dynamic cable design for floating offshore wind and high-voltage power transmission, through 66kV cable technology. JDR was recently awarded the world’s first large-scale commercial 66kV project, for the East Anglia One wind farm, in the UK.
