ZWIJNDRECHT, Belgium – DEME Offshore has received the EPCI contract for the inter-array cables for the first two phases of the Dogger Bank wind farm in the UK North Sea.
The work scope includes engineering, procurement, construction, and installation of 650 km (404 mi) of 66 kV inter-array cables and all related accessories.
Located more than 130 km (81 mi) offshore northeast England, the 3.6-GW Dogger Bank wind farm is currently being developed in three 1.2 GW phases by joint venture partners SSE Renewables and Equinor.
The contract is subject to the final investment decision (FID) on Dogger Bank A and Dogger Bank B, which is expected in late 2020. FID on Dogger Bank C is expected in late 2021.
Cable production is expected to start next year.
The Living Stonewill install the cables. The DP-3 cable installation vessel features a DEME-designed dual-lane system, consisting of two cable highways – one for laying the cable and one where the next cable can be simultaneously prepared and have the cable protection system installed. This reduces the time needed for preparing the cables, minimizes manual handling, increases the vessel’s workability, and improves production rates, the company said.
Halfdan Brustad, vice president for Dogger Bank at Equinor said: “Dogger Bank wind farm is pioneering new technology, and at the forefront of scaling up significant energy infrastructure. This contract, for the largest ever order for inter array cables, demonstrates the sheer scale of this project.”
