Who are McDermott International, Ltd.'s core customers in the global energy infrastructure and offshore markets?
McDermott International, Ltd. serves major oil & gas operators, national oil companies, and offshore wind developers; these clients drive multi-year EPCI spending cycles. Rising 2025 offshore renewables contracts and sustained LNG capex justify focused attention on this customer set.

Core buyers favor scale, risk-sharing, and integrated EPCI capabilities; McDermott widens appeal by adding low-carbon engineering services and fabrication partnerships. See McDermott Business Model Canvas for product-level detail.
WWho Is McDermott Built For?
McDermott International, Ltd. is built to serve high-capital energy and industrial clients, chiefly National Oil Companies (NOCs) and Tier-1 International Oil Companies (IOCs) requiring large-scale EPCI delivery, plus growing volumes from LNG and carbon-capture developers.
NOCs in the Middle East - notably Saudi Aramco and QatarEnergy - are the core customers of McDermott, sourcing mega-project EPCI services where individual contracts commonly exceed USD 1 billion. These clients demand integrated engineering, procurement, construction, and installation at scale; McDermott customer profile centers on delivering that scale and technical scope.
Tier-1 IOCs such as Shell, Chevron, and TotalEnergies form the secondary McDermott clients, especially for deepwater subsea and offshore platforms. Industrial players and utilities hire McDermott for large LNG liquefaction trains and downstream petrochemical units, expanding McDermott client industries beyond traditional upstream work.
McDermott serves businesses and government-owned enterprises (institutions) rather than consumers; its market role is as an EPCI contractor for capital-intensive energy infrastructure, including oil and gas, LNG, and carbon-capture projects.
In 2025-2026 the most commercially important segment remains Middle East NOCs and large LNG projects: McDermott reported a project backlog and awarded contracts mix weighted heavily to the region, with individual contract values and backlog positions often in the hundreds of millions to several billions of dollars, reflecting where revenue growth and margins are concentrated.

WWhat Do McDermott's Customers Care About Most?
Core customers of McDermott International, Ltd. prioritize certainty of execution, technical de-risking, and measurable decarbonization; they need integrated single-vendor delivery, modular fabrication to cut offshore labor, and hydrogen-ready designs to protect asset value.
Buyers-mainly energy companies and major oil majors-seek firms that remove interface risk between engineering, procurement, and installation. They demand track records of on-time delivery and lower schedule variance, especially for large offshore EPCIC (engineering, procurement, construction, installation, and commissioning) projects.
Customers choose McDermott for integrated, single-contract models that reduce contractor interfaces and change-order exposure. Modularization-off-site yard fabrication-cuts offshore labor costs and can reduce installation schedules by 20-30% on comparable projects.
Procurement and project directors prefer partners seen as reliable and forward-looking; winning vendors signal lower political and reputational risk. Clients value suppliers that visibly commit to ESG and energy-transition readiness.
Customers prioritize demonstrable technical solutions that reduce cost and carbon intensity during construction. They require hydrogen-ready designs for traditional gas assets to avoid stranded-asset risk and expect carbon metrics reported across scope 1-3 construction activities.
Repeat business follows successful delivery of large EPCIC projects with low claims and predictable margins. Long-term frameworks with energy majors and utilities-often multi-year-drive retention and pipeline visibility.
Clients pick McDermott for integrated offshore and onshore execution, modular yard capability, and engineering that aligns with decarbonization goals. For context on market positioning and recent wins see Product Growth of McDermott Company.

WWhere Is Demand Strongest for McDermott?
Demand for McDermott International, Ltd. is strongest in the Middle East and the Gulf of Mexico, driven by offshore platform and large EPC backlogs; 2025 also shows rising Asia-Pacific demand for SURF systems and strong onshore LNG CAPEX in the United States and West Africa.
The Middle East supplies the largest backlog for McDermott due to multi-year contracts for jackets and topsides in Saudi Arabia and Qatar; Gulf of Mexico demand centers on brownfield and deepwater projects supporting repeat clients among major oil majors.
In 2025 Asia-Pacific saw a surge in subsea umbilical, riser, and flowline (SURF) work as countries prioritized energy security; onshore LNG export terminal construction is concentrated in the United States and West Africa, attracting McDermott clients for large EPC scopes.
McDermott International, Ltd. shows strength where heavy fabrication yards and a specialized marine fleet matter most-offshore topsides, jackets, and SURF systems-driving both revenue mix and repeat McDermott clients among oil majors and national oil companies.
Fastest growth in 2025 appears in Asia-Pacific SURF contracts and LNG export terminals in the US and West Africa; these trends expand McDermott customer segments into energy security projects and LNG clients, increasing project-size concentration in its orderbook.

HHow Does McDermott Broaden Appeal Without Losing Focus?
McDermott International, Ltd. broadens appeal by applying legacy EPCI offshore expertise to CCUS and offshore wind substations, winning green capital while keeping its heavy-engineering focus; by 2026 about 25% of its bidding pipeline targets low – carbon projects while traditional upstream work remains dominant.
McDermott leverages EPCI (engineering, procurement, construction and installation) know – how to pursue CCUS and offshore wind substation contracts, capturing green capital without retraining away from heavy offshore engineering; this targets new McDermott customer segments in renewables and carbon management.
The firm keeps focus on complex offshore oil and gas projects-its primary clients remain national oil companies and international oil majors-ensuring steady revenue from legacy EPCI contracts and preserving relationships that define the McDermott customer profile.
Repeat demand arises from high – complexity, high – moat projects where Tier – 1 clients value delivery certainty; long project cycles and integrated EPCI services increase ecosystem stickiness among McDermott clients in oil and gas sector and utilities.
The strongest growth lever is disciplined portfolio balance: maintaining traditional upstream market share while allocating roughly 25% of the bid pipeline to low – carbon projects, which provides credible revenue diversification into the net – zero economy without over – diversification.
