Jan De Nul Group has been awarded a contract for the transport and installation of 87 turbines at the Dogger Bank C wind farm off the coast of Yorkshire, England.

The contract award is the third award for Jan De Nul related to the Dogger Bank project. The 3.6 GW Dogger Bank Wind Farm will be the world’s largest, developed in three 1.2 GW phases (A, B and C). With the latest award, Jan De Nul has plans to install a total of 277 wind turbine generators.

For Dogger Bank C, Jan De Null will transport and installed 14 MW turbines using its new offshore jack-up vessel Voltaire, which is currently under construction and due for delivery 2022.

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 timeframe and is owned by SSE Renewables (50%) and Equinor (50%). Dogger Bank C is planned to reach financial close by the end of 2021.

When complete, Dogger Bank will generate enough energy to power over 6 million UK homes every year.

“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,” said Steve Wilson, Dogger Bank Wind Farm’s Project Director at SSE Renewables. “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.”

“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,” added Philippe Hutse, Director Offshore Division at Jan De Nul Group.
