DEME Offshore has been awarded an EPCI contract for the inter-array cables at the Dogger Bank A and Dogger Bank B wind farms in the UK, the first two phases of the 3.6 GW Dogger Bank Wind Farm which is the world’s biggest offshore wind farm under development.
The scope includes the engineering, procurement, construction and installation of the subsea cables for the combined 2.4 GW wind farm. DEME Offshore will supply, install and protect 650 km of 66 kV inter-array cables and all related accessories.
Dogger Bank Wind Farm is located more than 130 km off the North East coast of England and is currently being developed in three 1.2 GW phases by joint venture partners SSE Renewables and Equinor.
Production of the cable for Dogger Bank A and Dogger Bank B will start in 2021 and will be installed using the state-of-the-art DP3 cable installation vessel Living Stone. She was selected based on her cable capacity of more than 10,000 tonnes, and proven track record. The Living Stone boasts 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 (CPS) installed. This significantly reduces the time needed for preparing the cables, minimises manual handling, increases the vessel’s workability and ultimately, improves production rates. DEME Offshore will work closely with SSE Renewables and Equinor to engage with the UK supply chain in the delivery of the project.
The contract with DEME Offshore is subject to joint venture partners SSE Renewables and Equinor reaching Financial Close on Dogger Bank A and Dogger Bank B, expected in late 2020.
