JDR Cable Systems, Ltd., reports that it has won a contract from Equinor to supply the cables for the first floating offshore wind project to power oil and gas platforms.

A press release said that the project calls for JDR to supply 11 66kV dynamic inter-array cables (2. 5 km long each) and two static export cables (one 12. 9 km, the other 16 km), each equipped with a JDR designed breakaway system, and a range of cable accessories. The off-shore location is in the Tampen area in the North Sea, and delivery is scheduled for 2022.

The project, the release said, will be the first worldwide to power oil and gas platforms using floating offshore wind, which it described as “a far more technically challenging and less mature technology than traditional fixed-foundation offshore wind.” It said that cables pose a particular challenge due to the high dynamic stress they must withstand.

The Hywind Tampen project will consist of 11 wind turbines developed by Equinor. The 8 MW turbines will have a total capacity of 88 MW, capable of meeting about 35 per cent of the annual power demand of the five Snorre A and B, Gullfaks A, B and C oil and gas platforms. The floating wind project is in water depths of 300 meters, much deeper than any previous floating wind project and is the first ever to power oil and gas platforms. The cabes that will be delivered to connect the loop to the Snorre A and Gullfaks A platforms will be especially designed to withstand higher water pressures.

JDR, part of Poland’s TFKable Group, notes in the release that it has already been active in the fledgling sub-sector of this new niche, delivering the world’s first application of dynamic 66kV technology and breakaway system to the Windfloat Atlantic floating wind farm last year. The power cores for the cables will be manufactured by JDR’s parent company TFKable at its Bydgoszcz factory in Poland. All the cables and accessories will be assembled at JDR’s U.K. facilities in Hartlepool.
