Jan De Nul

Our expertise

Offshore, marine, civil, environment and project development. Jan De Nul Group is a leading expert in five main activities.

Jan De Nul Group shapes both water and land. We enable the production of offshore energy and maintain the depth of waterways. We build new ports and create extra land. We realise complex infrastructure works and erect any type of building. We tackle pollution in whatever form. Thanks to the fruitful interaction within our company, we can offer overall solutions that combine one, several or even all these activities.

Latest Projects


We are collaborating with partners from science and government on the first offshore pilot project for large-scale oyster reef restoration in the Belgian North Sea.


In 2023, we connected the power grids of Scotland and the Orkney island of Hoy via the Pentland Firth sea route.
