The world’s global EPC contractors — firms that deliver Engineering, Procurement and Construction services under a single contract — are the builders of the energy infrastructure that underpins global oil, gas and chemicals production. In 2026, the oil and gas EPC market is valued at approximately $479 billion and is growing at a CAGR of 4.76%, driven by LNG terminal investment, refinery modernisation, petrochemical expansion and a rapidly growing pipeline of energy transition projects spanning hydrogen, carbon capture and offshore wind. This ranking assesses the ten largest global EPC contractors by revenue, order backlog and strategic market position in oil, gas and energy infrastructure delivery.
How We Ranked the Top 10 Global EPC Contractors
Global EPC contractors are ranked primarily by annual revenue and order backlog — the two metrics that best reflect current market scale and near-term delivery capacity. Fleet capability (for offshore contractors), geographic reach, sector specialisation (LNG, offshore, onshore processing, refining) and 2025–2026 contract wins are used as secondary indicators. The EPC sector spans both publicly listed companies and major private firms; where precise revenue figures are unavailable for private entities, publicly disclosed backlog and project portfolio data are used. The global EPC landscape is tracked by publications including the Engineering News-Record (ENR), whose annual Top 250 Global Contractors ranking is the industry reference for scale comparison.

The Future of Global EPC Contractors: What to Watch in 2026
The Saipem7 merger — combining Saipem and Subsea 7 into a €43 billion backlog offshore EPCI giant — is the defining corporate event in the global EPC sector in 2026. Beyond consolidation, three technology shifts are reshaping competitive dynamics: the adoption of AI-driven digital twins across project execution (led by Bechtel, Worley and McDermott), the growth of modular prefabrication as a cost and schedule management tool (Fluor’s January 2026 pipeline announcement), and the rapid expansion of energy transition EPC work — hydrogen facilities, carbon capture plants and offshore wind foundations — that now accounts for a material share of backlog at every contractor in this ranking. The contractors who master both the hydrocarbon project pipeline and the emerging new energy infrastructure build will define the next decade of global EPC competition.
Who are the largest global EPC contractors in oil and gas in 2026?
The largest global EPC contractors in oil and gas in 2026 are Bechtel Corporation (USA), Larsen & Toubro Hydrocarbon (India), Saipem/Saipem7 (Italy), Fluor Corporation (USA), McDermott International (USA), Worley (Australia), TechnipFMC (UK), KBR (USA), Technip Energies (France) and Samsung E&A (South Korea). Together these firms deliver the majority of the world’s largest LNG facilities, offshore platforms, petrochemical complexes and energy transition infrastructure projects.
What is the global oil and gas EPC market worth in 2026?
The global oil and gas EPC market is valued at approximately $479 billion in 2025 and is projected to grow at a CAGR of 4.76% to reach approximately $604 billion by 2030. North America accounts for approximately 34% of the market by value, driven by US LNG export terminal investment and shale infrastructure. Asia-Pacific is the fastest-growing region, fuelled by refinery expansion and petrochemical development in China, India and Southeast Asia.
What is the Saipem7 merger and when will it close?

The transaction is expected to close in the second half of 2026, creating one of the world’s largest offshore EPCI contractors by backlog and revenue.
What is the difference between EPC and EPCI contracts?
EPC (Engineering, Procurement and Construction) contracts cover the design, procurement of materials and equipment, and construction of a facility to a defined specification. EPCI (Engineering, Procurement, Construction and Installation) contracts extend this scope to include the offshore installation of structures such as platforms, subsea pipelines and FPSO turret systems — typically relevant for marine and offshore projects. Contractors like Saipem, Subsea 7 and TechnipFMC specialise in EPCI work using their fleets of construction and pipelay vessels.
How is the energy transition affecting global EPC contractors in 2026?
Energy transition projects — including LNG facilities, hydrogen production plants, carbon capture infrastructure and offshore wind foundations — now represent a material and growing share of backlog at most major global EPC contractors. Worley leads with over 40% of revenues from sustainability-linked projects. Bechtel, Fluor and KBR are all active in LNG (which is treated as a transition fuel in most energy scenarios), while Technip Energies and Saipem are developing dedicated capabilities in hydrogen, CCS and offshore wind EPCI work. The EPC contractor that can deliver both conventional and new energy infrastructure at scale will hold the strongest competitive position through 2030.
