Earlier this year, the Carbon Trust picked five winners of a dynamic export cable competition within its Floating Wind Joint Industry Project (Floating Wind JIP).
A press release said that the successful companies were Norway’s Aker Solutions, Japan’s Furukawa Electric, Greece’s Hellenic Cables, JDR Cable Systems in the U.K. and Zhongtian Technology Submarine Cable in China. The goal is to draw on the expertise of existing offshore wind cable suppliers and the oil and gas supply chain to "support the design, initial testing and development of dynamic cables ranging from 130 kV to 250 kV to enable the efficient transmission of power from floating wind turbines to shore."
The results of the first phase of the project, which will conclude in March 2020, could help to "inform subsequent project phases to support the deployment of dynamic export cables across the industry," the release said.
"The lack of dynamic export cables has been identified as a hurdle that needs to be overcome by industry to ensure the commercialization of floating wind farms, and we are excited to begin work to ensure that this technology is ready in time for commercial floating wind projects," said Carbon Trust offshore wind manager Rory Shanahan. "We are delighted with the response we got from the industry and we are looking forward to working with the five competition winners."
BPP Cables is supporting the competition, which aims to ensure that this necessary technology is a viable option for developers for commercial floating wind projects within the next five to 10 years.
At its website, the U.K.-based organization describes Carbon Trust as "an independent, expert partner of leading organizations around the world, helping them contribute to and benefit from a more sustainable future through carbon reduction, resource efficiency strategies and commercializing low carbon technologies."
In 2017, the Carbon Trust’s Offshore Wind Accelerator (OWA) initiative "launched a new global innovation competition to find and fund the development of innovative solutions to a challenge facing the offshore wind farm industry today: how to monitor the condition of subsea cables to ensure that they are not damaged during the load out and installation process. The competition seeks to identify and support the development of novel condition monitoring systems for subsea cables. "Looking at £213 million in insurance losses from 28 UK offshore wind claims between 2002 and 2015, 68% were directly due to cable faults occurring predominately during the construction phase."
U.K.-based JDR Cable Systems (JDR) reports that it has won a multi-million pound contract to supply inter-array cables and termination work for Ørsted’s record-breaking, 1.4 GW offshore wind farm, Hornsea Project Two.
A press release said that, when operational in 2022, the wind farm will supply electricity to over 1.3 million homes, and surpass its sister project Hornsea One, as the world’s largest offshore wind farm. The contract calls for JDR, part of Poland’s TFKable Group, to supply 100 km of inter-array cables that will be assembled in JDR’s Hartlepool facility. The inter-array cables link the wind farm turbines together, and carry the power to an offshore substation, which converts it to a higher voltage for transmission to shore.
The project, the release said, is Ørsted’s first in the U.K. to use 66 kV for its array cables, having used 33kV for previous projects. Using cables with a higher voltage helps to reduce electrical losses during transmission.
“This contract builds on experience from previous projects including Race Bank offshore wind farm, which we opened earlier this year, and Hornsea Project One, currently in construction,” said Patrick Harnett, the procurement and construction director for the project. “As our wind farm projects have grown in size, and distance from shore, so too have the contracts we place within the supply chain. The technology we use is also changing as we innovate to build these projects at massively lower cost of electricity into the U.K.’s grid.”
JDR CEO Richard Turner said that, “Hornsea Project Two ... will be built at the lowest ever price seen in the U.K.”
JDR Cable Systems reports that it has been awarded a contract by McDermott in the Persian Gulf for a project described as the world’s largest offshore oilfield.
A press release said that the contract for the project, owned and operated by Saudi Aramco, includes five thermoplastic umbilicals and hardware connecting new production platforms to the subsea valve skid (SSVS). The umbilicals, which range from 100 to 465 meters in length, will provide hydraulic and electric control to the SSVS.
The contract with McDermott is part of a larger program by Saudi Aramco to replace Safaniya’s aging facilities with electrified platforms to increase the efficiency and production of the field. The field is located 125 miles north of Dhahran in the Arabian Gulf and is estimated to contain 37 billion barrels of oil reserves.
“This is our fifth combined contract for the Safaniya field and truly demonstrates the quality and reliability of our products, said Chris Green, subsea production umbilicals sales manager at JDR, which was acquired last year by TFKable Group. He noted that speed of delivery was a key element of winning the order. The umbilicals will be manufactured at JDR’s plant in Littleport, U.K., with delivery scheduled for Q4 2018.
