Voltaire

Joining forces to build the world’s largest installation vessels

We want to continue playing a leading role on the offshore energy market

That was the trigger for developing our new vessels, the Voltaire and Les Alizés, because you simply need the most powerful installation vessels.

“To boldly go where no man has gone before.” That is exactly what Jan De Nul does with the Voltaire and Les Alizés, the world’s largest and most powerful installation vessels of their kind (one on legs, one floating) that will build the next generation of offshore wind farms. Offshore Renewables, New Building, Finance: various Jan De Nul departments have joined forces to bring this mega-project to a successful conclusion. From its earliest concept up to the vessels’ launch. Global concern for the imminent climate change has given wind energy an enormous boost. The demand for offshore wind farms is increasing exponentially.
