Efficient and clean installation with Jack-Up vessel Voltaire
For the delivery and installation of the 14 MW turbines, Jan De Nul Group will mobilise its newest Next Gen Offshore Jack-Up Installation Vessel Voltaire, turning this project into her first assignment. The contract is subject to Dogger Bank C reaching Financial Close in late 2021.
Building the world’s largest offshore wind farm off the English coast
The 3.6 GW Dogger Bank Wind Farm, which is being delivered in the North Sea in three 1.2 GW phases, is set to be the world’s largest offshore wind farm when complete.
The first two phases, Dogger Bank A and B, each feature 95 units of 13 MW turbines. They are a joint venture between Equinor (40%), SSE Renewables (40%) and Eni (20%). The third phase, Dogger Bank C, is being developed on a different timescale and is owned by SSE Renewables (50%) and Equinor (50%).
When complete, Dogger Bank will generate enough energy to power over 6 million UK homes every year.
Dogger Bank Wind Farm secured 3.6 GW of offshore wind contracts in the UK Government’s 2019 contracts for difference auctions. Record low prices were awarded for the three phases making up Dogger Bank Wind Farm: Dogger Bank A, Dogger Bank B and Dogger Bank C. Dogger Bank C is planned to reach financial close by the end of 2021.
SSE Renewables is leading the development and construction phases of Dogger Bank Wind Farm and Equinor will lead on operations for its lifetime of up to 35 years.
Steve Wilson, Dogger Bank Wind Farm’s Project Director at SSE Renewables, said: “Jan De Nul Group has a great track record for the transportation and installation of turbines on scale, and offshore wind farms don’t come any bigger than ours. With a lifting capacity of more than 3,000 tonnes, the ultra-clean Voltaire vessel is set to become the world’s largest jack-up vessel when it enters service in 2022. Securing this state-of-the-art vessel for all three phases of Dogger Bank Wind Farm is another reminder of how we’re working with our suppliers to drive innovation in offshore wind.”
Halfdan Brustad, Vice President for Dogger Bank at Equinor, said: “We are extremely pleased to have secured the Voltaire for the third phase of Dogger Bank, as it will follow the turbine installations for phases A and B. By the time Dogger Bank Wind Farm is complete, this low emissions vessel will have installed 277 of the world’s most powerful turbines at the world’s biggest offshore wind farm; quite a feat for The Voltaire’s first assignment! This continued contract with Jan De Nul demonstrates world class innovation delivering at scale, both important factors in ensuring we build Dogger Bank as efficiently and sustainably as possible.”
Philippe Hutse, Director Offshore Division at Jan De Nul Group, said: “Dogger Bank Wind Farm is exactly the type of project we had in mind when we took the decision to build our Voltaire. The scale and characteristics of the offshore Dogger Bank and turbines offer the perfect challenge for this Next Gen Offshore Jack-Up Installation Vessel. We are proud to be recognised in our choices and look forward to working together with industry leaders SSE Renewables and Equinor on the Dogger Bank C phase of this world-leading project. We are excited to take part in the worldwide transition to renewable energies by installing the offshore wind turbines at Dogger Bank A, B and C in the most efficient and clean manner possible.”
First seaworthy installation vessel to be an Ultra-Low Emission vessel
This Offshore Jack-Up Installation Vessel Voltaire is currently under construction. She will have a lifting capacity of over 3,000 tonnes and will enter into service in 2022.
She is named after the pioneering European Enlightenment philosopher and is fitted with a highly advanced exhaust filtering system by means of a Selective Catalytic Reduction system and a Diesel Particulate Filter, making it the very first seagoing installation vessel of its kind to be an Ultra-Low Emission vessel (ULEv), moreover Stage V-certified.
We are excited to take part in the worldwide transition to renewable energies by installing the offshore wind turbines at Dogger Bank A, B and C in the most efficient and clean manner possible.

About Dogger Bank Wind Farm
The 3.6 GW Dogger Bank Wind Farm will be the world’s largest offshore wind farm when completed in 2026. It is being built in three 1.2 GW phases: Dogger Bank A, B and C.
- Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%).
- Dogger Bank C is a 50:50 joint venture between Equinor and SSE Renewables. SSE Renewables is lead operator for the development and construction of Dogger Bank Wind Farm. Equinor will be lead operator of the wind farm for the duration of the wind farm’s operational phase.
Financial Close on Dogger Bank A and Dogger Bank B was reached in November 2020. Financial Close for Dogger Bank C is expected in late 2021. Consent for Dogger Bank Wind Farm was granted in 2015.
- Each of the three phases of Dogger Bank Wind Farm secured 15-year CfD contracts for 1.2GW of low carbon power for of low carbon power production in the UK’s third CfD Allocation Round, announced September 2019.
- In May 2021, Dogger Bank Wind Farm took another major step forward after passing a required delivery milestone under the UK’s Contracts for Difference scheme for low carbon power.
Almost 3000 new UK jobs have been announced so far that will be supported by the construction and operation of Dogger Bank Wind Farm. These include up to 750 direct and around 1,500 indirect jobs associated with the set-up of a new world-class blade manufacturing facility on Teesside by LM Wind Power, a GE Renewable Energy business, with production due to start in 2023.
Dogger Bank Wind Farm is located in the North Sea, with each phase more than 130km from the Yorkshire Coast.
- Onshore construction began in 2020 and is currently underway for Dogger Bank A and Dogger Bank B.
- Offshore construction on Dogger Bank A is 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 6 months later.
- Turbine installation for Dogger Bank C will begin in 2025.
Dogger Bank A and B has confirmed GE’s Haliade-X 13MW as the turbine powering the first two phases of the project. As the first order for the Haliade-X 13MW, installation at Dogger Bank A will be the first time the turbine is installed in the world. Installation of GE’s upscaled Haliade-X 14MW turbine at Dogger Bank C will be the first time the 14MW turbine is installed in the world.
- One rotation of the Haliade-X turbine blades can power one UK home for more than two days.
- The wind turbines will be installed on monopile foundations.
- The project will be the first High Voltage Direct Current (HVDC) connected wind farm in the UK due to its distance from shore, introducing new transmission systems to the UK and paving the way for other large offshore wind farms.
