Cenergy Holdings has announced that Hellenic Cables, its cables segment, has been awarded the Dogger Bank C array cable contract by DEME Offshore, the renewables business unit of DEME Group. Already the designated cables supplier for Dogger Bank A and B, Hellenic Cables becomes with this contract the sole inter-array cables’ supplier for the project.


Under the new contract, Hellenic Cables will design, manufacture, test, and supply approx. 240 km of 66 kV XLPE-insulated inter-array cables and associated accessories.  This is in addition to the 650 km of array cables already awarded for phases A & B.  The cables will be produced at Hellenic Cables’ plant in Corinth, Greece. Production of the cables for Dogger Bank C is set to begin in 2023 and delivery will be a phased roll out in line with the project execution program.


“We are proud to be the exclusive array cables supplier for the world’s largest offshore wind farm, which provides the UK’s largest single source of renewable energy. Dogger Bank C reinforces the position of Hellenic Cables as enabler of the clean energy transition”
commented Mr. Alexis Alexiou, CEO of Cenergy Holdings.


“Over the past years, DEME Offshore and Hellenic Cables have been successfully delivering large-scale cable projects together. We very much look forward to partnering each other again and leveraging our joint expertise to deliver this major project”
said Mr. Bart De Poorter, General Manager DEME Offshore.


Dogger Bank A and Dogger Bank B are 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) for a total consideration of £140m. The transaction is expected to close in Q1 2022, subject to regulatory and lenders approvals and customary purchase price adjustments. 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%). Extended partner alignment will enable further synergies across, both in the construction and operations phase of the Dogger Bank wind farm.

SSE Renewables is leading on the development and construction of Dogger Bank Wind Farm, and Equinor will operate the wind farm on completion for its expected operational life of around 35 years.


Onshore construction is currently underway for Dogger Bank A and Dogger Bank B, with offshore construction on Dogger Bank A due to begin in Q2 2022. First power is expected in Summer 2023 and Summer 2024 for Dogger Bank A and B, respectively, with commercial operations to follow around six months later.

Onshore cable installation civil works for Phase C will start in Q1 2022; construction of the onshore convertor station will commence in Q2 2022. Offshore export cable installation will commence in Q1 2024; Offshore platform installation will commence in Q2, 2024; foundation installation will commence in Q3, 2024; Turbine installation will commence in Q2, 2025.
