DEME Offshore has been awarded an EPCI contract for the array cables at the Dogger Bank C wind farm in the UK.
Dogger Bank C is the third phase of the project, which is the world’s largest offshore wind scheme under development.
DEME Offshore was awarded the contract to install the Dogger bank A and B array cables in early 2021.
The scope of the new EPCI agreement includes the engineering, procurement, construction and installation of the subsea cables for the 1.2GW phase of the wind farm.
DEME Offshore will supply, install and protect approximately 250km of 66kV inter-array cables and all related accessories.
Production of the cable for Dogger Bank C is set to start in 2023.
The cables will be installed in 2025 and DEME will once again be deploying its DP3 cable installation vessel Living Stone.
Living Stone has an inhouse-designed dual-lane system, consisting of two cable highways.
This allows cable laying using one lane whilst the next cable can be simultaneously prepared and have the cable protection system (CPS) installed on the other lane.
This reduces the time needed for preparing the cables, minimises manual handling, increases the vessel’s workability and ultimately, improves production rates.
Bart De Poorter, general manager of DEME Offshore, said: “After securing the Dogger Bank A and B inter-array cable contract earlier this year, we are proud to now also confirm the inter-array cable contract for the Dogger Bank C wind farm.
“This contract not only demonstrates the unrivalled cable-laying capabilities by our DEME Offshore team, it is also further testament to the stellar reputation of our DP3 cable installation vessel ‘Living Stone’.”
Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). On 2 November 2021 SSE and Equinor announced the sell down of a combined 20% share in Dogger Bank C to Eni (10% each).
The transaction is expected to close in early 2022.
Eni will enter the asset effective from completion of the sell down transaction. Once the transaction is complete, the new overall shareholding in Dogger Bank C will be SSE Renewables (40%), Equinor (40%) and Eni (20%).
