A year after enjoying a "fantastic year" by surpassing the mark for the first time the symbolic milestone of €4 billion in turnover, Jan De Nul is continuing its momentum. The group, which specialises in dredging, maritime infrastructure and offshore energy, announced on Thursday 21 May that it had set a new record for 2025 of €4.24bn, up 6% year-on-year.
The pace has slowed compared to the boom of 2024, when the company saw a 36% surge, but the trajectory remains impressive. In three years, Jan De Nul – historically based between Belgium and Luxembourg, where its headquarters are located in Capellen, and employing nearly 8,850 people worldwide – has virtually doubled in size. Following 18% growth between 2022 and 2023, then the historic surge of 2024, the group is now enjoying a fourth consecutive record year. Profitability is following the same trend. EBITDA rose from €777m in 2024 to €812m in 2025. Net profit climbed by 12% to €458m, having already surged to €409m the previous year.
50% of revenue in Europe
The maritime sector remains the clear driving force. Activities relating to dredging, offshore infrastructure and offshore energy now account for 74% of turnover, down from 77% in 2024. Jan De Nul continues to benefit from the global wave of investment in offshore wind and subsea power interconnections. The installation of cables for the Danish Thor wind farm illustrates the growth of a market that has become strategic for European energy security.
Geographical expansion remains extensive. In 2024, Jan De Nul was carrying out 302 projects across 35 countries. In 2025, the group has 298 projects spread across 31 countries. Europe remains its largest market, accounting for over 50% of revenue, driven by the boom in offshore energy projects. The Middle East, Asia and the Americas also remain strategic regions.
The strategy is clear: to strengthen its position in global energy infrastructure whilst modernising its fleet and onshore equipment. Jan De Nul is also focusing on innovative decontamination technologies, particularly for treating PFAS contamination. “Jan De Nul’s strong financial position, notably the absence of net debt, enables us to invest in new vessels, onshore equipment and research. We are ready for the future,” says CFO Jan Neckebroeck.
