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.

DEME Group competitors and assessment
Company assessmentDirect peers
- Saipem: Saipem is an Italian oil & gas and renewable energy EPCI contractor with offshore wind installation capabilities. Competes with DEME on offshore wind EPCI tenders and brings comparable integrated project delivery capabilities, though with stronger oil & gas legacy exposure.
- Jan De Nul Group: Jan De Nul is a Belgian-headquartered family-owned dredging and marine construction company with comparable offshore wind installation capabilities (Voltaire WTIV). Direct competitor particularly in European offshore wind and dredging tenders, with overlapping Belgian heritage and customer base.
- Subsea 7: Subsea 7 is a UK-based offshore engineering and subsea construction contractor serving the offshore wind and oil & gas markets. Comparable in offshore installation services, particularly cable laying and subsea work for offshore wind farms where DEME operates Living Stone and Viking Neptun vessels.
- Van Oord: Van Oord is a Dutch marine contractor specializing in dredging, offshore wind installation (including the new Boreas WTIV), and coastal infrastructure. Closest direct peer with overlapping fleet, customer base, and competitive bidding in offshore wind and port construction.
- Royal Boskalis Westminster: Royal Boskalis Westminster is a Dutch marine services and dredging contractor with comparable scale and product portfolio across dredging, offshore energy installation, and marine services. Direct head-to-head competitor on major port dredging and offshore wind EPCI tenders globally.
- Heerema Marine Contractors: Heerema is a Dutch offshore construction contractor specializing in transportation, installation, and removal of offshore structures. Comparable in heavy-lift offshore installation, including offshore wind foundation and substation installation work that overlaps with DEME's offshore energy segment.
Broad incumbents
- McDermott International: McDermott is a US-based global engineering and construction contractor serving offshore energy markets including offshore wind. While focused more on oil & gas EPCI, the company is pivoting toward offshore wind and competes with DEME on integrated EPCI scopes for major offshore projects.
Regional players
- Great Lakes Dredge & Dock: Great Lakes Dredge & Dock is a US-based dredging services contractor serving primarily the US market. Comparable in core dredging capability but regionally focused on North America, with no direct overlap in European/Asian offshore wind markets where DEME primarily operates.
- Penta-Ocean Construction: Penta-Ocean is a Japanese marine and civil engineering contractor with dredging and reclamation capabilities. Comparable in marine construction and offshore wind installation techniques, but primarily serves Japan and Asia with limited overlap with DEME's European stronghold.
Others
- Orsted (offshore wind developer/operator): Orsted is a Danish offshore wind developer and operator, the largest globally. While not a direct contractor competitor, Orsted is a major customer for DEME's offshore installation services and a benchmark for the offshore wind value chain where DEME operates as an installation contractor.
