History

The trailing suction hopper dredger Alexander von Humboldt

Founded in 1938 in Hofstade, near Aalst, Belgium, Jan De Nul started as a construction company specialised in civil works and maritime construction. It was only in 1951 that the company entered into the dredging business. Recently, it has forayed into offshore wind business, including European wind energy projects.

At the end of 2023, Jan De Nul had 7491 employees and a yearly turnover of 2.9 billion euro.[1] Other major dredging companies are Dutch companies Royal Boskalis and Royal Van Oord, and the Belgian DEME.[2]

Early 2025, Jan De Nul rebranded into World Builders, shaping water, land and energy. The focus of their new story is on the diversity of its activities and their social relevance as a solutions provider for challenges like the transition to renewable energy, soil and water pollution and coastline protection.

Jan De Nul was voted the most attractive employer in Belgium in 2008 and 2009.[3]
