Jan De Nul Group

Jan De Nul Group, the trade name of Sofidra S.A., is a family-owned marine construction contractor headquartered in Aalst, Belgium, with its registered office and financial headquarters in Capellen, Luxembourg. The group operates worldwide across four main activities: Offshore Energy, Dredging Solutions, Construction Projects and Planet Redevelopment. Its business spans capital and maintenance dredging, land reclamation, port and waterway construction, complex civil infrastructure such as bridge extensions, and environmental remediation and redevelopment of polluted sites. In offshore energy, Jan De Nul delivers integrated EPCI and transport-and-installation solutions across the full life cycle of offshore structures. Using a large in‑house designed fleet of specialised vessels – including jack-up and heavy lift installation vessels such as Voltaire and Les Alizés, cable-lay vessels Isaac Newton, Connector and Willem de Vlamingh, and subsea rock installation vessels – the company installs foundations, wind turbines, offshore substations, subsea power cables and umbilicals, and provides seabed preparation, scour protection, rock installation and decommissioning. It has executed major offshore wind and grid projects including Dogger Bank in the UK, Saint-Nazaire in France, Greater Changhua and Formosa 2 in Taiwan, Gode Wind 3 and Borkum Riffgrund 3 in Germany, Thor in Denmark, and export and inter‑array cable scopes and foundation installation for multiple European projects. Long-term charter and service agreements with developers such as RWE secure vessel capacity for large-scale wind farms including Thor, Hollandse Kust West VII and Inch Cape. The group operates a fleet of about 95 vessels and extensive heavy equipment, and reported 2024 revenue of around €4 billion with 8,801 employees. Its newbuild programme includes ultra-low emission vessels such as the subsea rock installation vessel George W. Goethals, equipped with ULEv exhaust treatment and alternative-fuel capability to reduce emissions from offshore operations.
