The jack-up vessel that will enter service for the first time to install the turbines on Dogger Bank Wind Farm has been officially launched.

Jan De Nul’s Voltaire will play a critical role in the installation of 277 GE Haliade-X turbines in the North Sea, more than 130km off the Yorkshire coast of England.

With a lifting capacity of more than 3,000 tonnes and a deck space equal to a football pitch, the ship is the largest of its kind in the world.

The next generation vessel was launched at the COSCO Shipping Shipyard in Nantong, China.

Steve Wilson, Dogger Bank Project Director, said:

“We congratulate Jan De Nul on successfully launching its unrivalled Jack up Vessel, the Voltaire. This impressive installation vessel will play a critical role in the construction of all three phases of Dogger Bank Wind Farm when it enters service, demonstrating an innovative engineering solution to the growing challenge presented by larger and more technically demanding wind farms.”

Dogger Bank wind farm agreed a contract with Jan De Nul for the transport and installation of turbines for the first two phases of the wind farm in 2019, with the Dogger Bank C contract following on last year.

The Voltaire will be able to run on second-generation biodiesel that reduces its fuel carbon footprint by up to 90%, and is also equipped with an advanced dual exhaust filter system, removing up to 99% of nanoparticles from emissions.

The launch of this environmentally-innovative vessel came just 20 days after Jan De Nul launched its Les Alizés ship to serve the growing demand from current and future wind farm projects.

Philippe Hutse, Director Offshore Division at Jan De Nul Group, said:

“The Voltaire will enable us to work in deeper waters and reach ever higher nacelle heights than before. Adding Voltaire and Les Alizés to the fleet gives us the perfect set of vessels to execute the growing number of large and clustered international offshore wind projects. Our forward-looking view on market trends and the quick decision making to invest in this set of Next Gen installation vessels, have done us no harm. The Voltaire and Les Alizés have all the required specifications to meet the upcoming challenges in offshore renewables. We are proud to be recognised for the choices we made back in 2019, and look forward to continuing our journey, alongside industry leaders, through our contribution to renewable energy growth in the worldwide energy transition.”
