What DEME Group does

DEME Group NV is a Belgian marine engineering contractor headquartered in Beveren-Kruibeke-Zwijndrecht, founded in 1876 and listed on Euronext Brussels (DEME) since 2022. The company operates through four segments: Dredging & Infra (capital and maintenance dredging, land reclamation, coastal protection), Offshore Energy (EPCI services for offshore wind including foundations, turbines, cables, and substations), Environmental (soil remediation, sediment treatment, brownfield redevelopment through DEME Environnement with recycling centers in Belgium and northern France), and Concessions (long-term infrastructure investments, offshore wind development stakes, green hydrogen, and deep-sea minerals via subsidiary GSR). DEME's fleet includes over 100 specialized vessels — most notably the next-generation wind turbine installation vessels Norse Wind and Norse Energi with 3,200-ton cranes acquired via the €900 million Havfram acquisition, the LNG-fueled installation vessel Orion, cable layers Living Stone and Viking Neptun, and trailing suction hopper dredgers Meuse River and Scheldt River.

DEME generates revenue primarily through project-based contracts secured via competitive tenders with governments, port authorities, and offshore wind developers. Pricing is determined by project scope, vessel utilization, technical specifications, and contract duration, with multi-year contract cadence. Customer segments include offshore wind developers and energy companies (RWE, Ocean Winds, Northland Power, Thistle Wind Partners), port authorities and governments (OMMP Tunisia, Navayuga Engineering in India, Belgian Federal Public Service), and industrial clients requiring environmental remediation. The GTM motion is enterprise field sales supplemented by event-driven presence at maritime and offshore wind industry conferences.

FY2025 turnover reached €4.2 billion (up from €4.1 billion in 2024), with EBITDA of €931 million (22.4% margin, up 22%) and net profit of €346 million (up 20%, more than double the €163 million two years prior). The order book stood at €7.4–7.6 billion at year-end 2025, and Q1 2026 order intake of €793M approximately doubled year-over-year. DEME employs nearly 6,000 professionals across more than 90 countries, with operational presence in Europe, Asia, the Middle East, Africa, and South America.
