The top engineering construction companies Europe turns to in 2026 are navigating a dual mandate: delivering conventional oil, gas, and LNG infrastructure while executing the offshore wind, hydrogen, and carbon capture projects defining the continent’s decarbonisation agenda. Combined backlogs across the leading EPC and offshore construction firms now exceed $150 billion. These are the ten companies with the deepest European footprint and the greatest influence on how that capital gets deployed.
How We Ranked the Top 10 Engineering & Construction Companies in Europe
Rankings are based on a combination of European project exposure, revenue scale, backlog size, and strategic positioning across both conventional energy and energy transition work. Companies are assessed on their active project portfolios in European markets, their proprietary technology capabilities where relevant, and their financial strength entering 2026. US-headquartered firms with major European operations are included where their European presence is material and strategically significant.
1. Saipem — Italy
Saipem leads this ranking on the strength of a €31.5 billion backlog — the largest of any European-headquartered EPC contractor — and 2025 revenue of approximately €15.5 billion. The Milan-based company is the dominant European player in offshore heavy construction, with a fleet including the Castorone pipelay vessel and the Saipem 7000 semi-submersible crane vessel. In Q4 2025 alone it secured a $3.1 billion QatarEnergy LNG compression package and $600 million from Saudi Aramco — confirming its position as the preferred contractor for technically complex offshore and LNG work globally. In Europe, Saipem’s offshore pipeline and subsea installation work on the Norwegian Continental Shelf and Mediterranean underpins its regional leadership. See our full Saipem company profile.
2. Technip Energies — France
Technip Energies is Europe’s leading engineering and technology company for LNG and energy transition infrastructure, reporting record revenue of €7.2 billion in 2025 with a backlog exceeding €15 billion. The Paris-based company has contributed to more than 20% of global LNG liquefaction capacity through its proprietary Liquefin™ and SMR™ technologies, and is targeting its highest-ever annual order intake in 2026 as LNG FIDs accelerate across North America and the Middle East. In Europe, its work spans sustainable fuels engineering, carbon capture technology through the Capture.Now™ platform, and process design for hydrogen and circular economy projects. See our full Technip Energies company profile.
3. Aker Solutions — Norway
Aker Solutions delivered record revenue of NOK 63.2 billion in 2025 with a secured backlog of NOK 64.8 billion — the strongest financial position in the company’s history. The Fornebu-headquartered company’s combination of deep Norwegian Continental Shelf engineering expertise, a 20% stake in SLB OneSubsea, and active participation in Northern Lights CCS and Hywind Tampen floating wind positions it as the defining Norwegian EPC contractor for both conventional and transition projects. A NOK 10 billion+ Equinor frame agreement awarded in Q1 2026 confirms continued preferred supplier status with its most important client. See our full Aker Solutions company profile.
4. Subsea7 — Luxembourg/Norway
Subsea7 posted revenue of $7.1 billion in 2025 with adjusted EBITDA of $1.48 billion at a 21% margin — a 36% year-on-year improvement — and closed the year with a record $13.8 billion backlog. Its fifth consecutive year of growth in the Subsea and Conventional segment, combined with Seaway7’s return to profitability in offshore wind installation, makes it the most financially robust pure-play offshore construction company in Europe. The company is guiding for revenue of $7.0-$7.4 billion in 2026 at an improving 22% EBITDA margin. See our full Subsea7 company profile.
5. Fluor Corporation — Netherlands/Global
Fluor operates one of Europe’s most significant EPC engineering hubs from Hoofddorp, Netherlands, executing major industrial and energy projects across the continent. Its 2025 revenue of $15.5 billion and $25.5 billion backlog — 81% reimbursable — confirm it as one of the largest EPC contractors active in European markets. Key European work includes engineering services for the Shell Energy and Chemicals Park Rotterdam and EPCM support for Neste’s renewable diesel expansion. Fluor’s strategic shift toward reimbursable contracting reduces the lump-sum execution risk that has troubled competitors and positions it strongly for continued European energy transition mandates. See our full Fluor Corporation company profile.
6. KBR — UK/Netherlands
KBR occupies a distinctive position in European engineering through its technology licensing model — owning more than 100 proprietary process technologies including KBR Purifier™ Ammonia and KBR Blue™ Hydrogen. Its Leatherhead, UK hub is the centre of excellence for European energy technology engineering, with active FEED and consulting work on blue hydrogen and decarbonisation projects across the UK and Northern Europe. FY2025 revenue of $7.8 billion and a $23.2 billion backlog and options total — up 13% year-on-year — demonstrate commercial strength. The planned H2 2026 spin-off of its Mission Technology Solutions segment will sharpen KBR’s commercial energy focus. See our full KBR company profile.
7. Wood (Sidara) — UK
Wood completed its acquisition by Dubai-based Sidara on 10 March 2026, ending its independent listing on the London Stock Exchange. The Aberdeen-headquartered engineering and consulting company employs approximately 35,000 people globally and holds long-term frame agreements with major North Sea operators across brownfield engineering, modifications, and operations support. Its energy transition credentials span Northern Lights CCS engineering, H2H Saltend hydrogen consultancy, and Dogger Bank offshore wind consultancy work. Under Sidara ownership, Wood retains its brand and management structure with new CEO Neil Bruce. See our full Wood Group company profile.
8. Petrofac (In Administration) — UK
Petrofac entered administration in October 2025 following the termination of its TenneT offshore wind contract and the collapse of a near-final balance sheet restructuring. Its Asset Solutions division was sold to CB&I in a transaction approved by 99% of creditors in January 2026, with approximately 3,000 employees transferring to CB&I. Petrofac Emirates, the UAE engineering and construction division, remains under M&A evaluation. While Petrofac no longer operates as a going concern in its previous form, it is included here for completeness given its historical significance as a major European EPC contractor and the active restructuring process still unfolding. See our full Petrofac administration profile.
9. TechnipFMC — UK/France/Norway
TechnipFMC is the subsea technology and services business that was separated from Technip Energies in the 2021 spin-off, listed on both the NYSE and Oslo Stock Exchange. It focuses exclusively on subsea production systems, well equipment, and associated services — operating through its Subsea and Surface Technologies segments. In Europe, TechnipFMC has a significant engineering and manufacturing presence across the UK, France, and Norway, supplying subsea trees, manifolds, flexible pipe systems, and integrated EPCI services to North Sea operators. The company reported 2025 revenue of approximately $8 billion and has been building its integrated iEPCI™ model — combining subsea technology supply with installation contracting — to capture a larger share of project value. Its European manufacturing facilities in Le Trait (France) and Dunfermline (UK) are central to its supply chain for global subsea projects.
10. McDermott International — Global/Europe
McDermott International re-entered the European market following its 2020 bankruptcy restructuring, refocusing on high-value LNG, gas processing, and petrochemical EPCI work where its proprietary process technology — including the Lummus Technology portfolio — provides a competitive differentiator. In Europe, McDermott’s engineering centres in the Netherlands and UK support LNG and downstream projects for major operators including Shell, TotalEnergies, and ADNOC. Its Lummus Technology subsidiary provides process technology licensing for ethylene, refining, and clean fuels — competing directly with KBR and Technip Energies in the technology licensing segment of the European market. See our full McDermott International company profile.
The Future of European Energy Engineering in 2026
The ten companies on this list collectively hold backlogs exceeding $150 billion, with the majority of new awards secured on reimbursable terms — a structural shift away from the fixed-price lump-sum contracts that generated major losses across the sector in 2018-2022. The combination of continued oil and gas capital spending, accelerating offshore wind buildout, and expanding CCS and hydrogen programmes provides these firms with a multi-decade pipeline of complex project work. The principal risk is execution — offshore and energy transition projects remain technically demanding, and the Petrofac collapse is a reminder that financial engineering cannot substitute for project delivery discipline.
