DEME Group NV is a global marine engineering and construction contractor with operations spanning across Europe, the Americas, Asia-Pacific, and Africa. The company operates through four primary segments: Offshore Energy, Dredging & Infra, Environmental, and Concessions. The Offshore Energy segment provides engineering, procurement, construction, and installation (EPCI) services for offshore wind farms, including foundations, turbines, and submarine cables, as well as services for the traditional oil and gas sector. The Dredging & Infra segment focuses on capital and maintenance dredging, land reclamation, coastal protection, and the construction of marine infrastructure such as port terminals and immersed tunnels. The Environmental segment offers soil remediation, brownfield redevelopment, and environmental dredging services. Finally, the Concessions segment invests in and develops greenfield and brownfield projects in offshore wind, marine infrastructure, and green hydrogen.
DEME generates revenue primarily by bidding for and executing large-scale marine and infrastructure contracts for governments, port authorities, energy companies, and industrial clients. In 2024, the company generated approximately €4.1 billion in total turnover, with the Dredging & Infra segment contributing nearly €2 billion and the Offshore Energy segment accounting for the majority of the remainder, alongside a smaller contribution from the Environmental segment. DEME's competitive position is supported by its specialized fleet of over 100 vessels—including heavy-lift, cable-laying, and fallpipe vessels—and its ability to execute complex projects in challenging marine environments.
