McDermott Company earns revenue primarily by delivering large-scale EPC (engineering, procurement, construction) contracts for oil, gas, and energy transition projects, with progress payments tied to project milestones and vessel-day rates for offshore installation services. In 2025 the company cited a project backlog above 18 billion dollars and about 65 percent of new awards from the Middle East, notably under a long-term agreement with Saudi Aramco, while low-carbon projects (offshore wind substations, CCS) are growing in the 2026 mix.

Main revenue: Large EPC contracts and milestone billing

Most revenue comes from lump-sum turnkey and reimbursable/cost-plus EPC contracts where milestone-based progress payments convert engineering and construction progress into cash inflows. This matters because project size and execution speed drive near-term cash and margin realization for an EPC contractor oil and gas specialist.

Additional revenue: Vessel fleet, specialized services, and long-term agreements

McDermott also earns daily vessel rates and subsea installation services fees, plus engineering, commissioning, and long-term support under LTAs; these add recurring cash and improve bid competitiveness on offshore engineering and construction jobs.

Pricing model: Fixed-price, cost-plus, and blended bids

The company uses lump-sum turnkey for predictable scopes and reimbursable/cost-plus for high-risk or early-stage work, blending vessel-day rates and equipment rental into bids so margins reflect risk allocation and contract type.

Primary revenue driver: Backlog composition and regional awards

Revenue depends most on project backlog scale and mix – volume from Middle East mega-awards and the share of reimbursable versus lump-sum work affect cash flow, margin volatility, and how McDermott manages cost overruns and subcontracting risks.

For investors tracking how McDermott makes money from EPC contracts, note the shift toward low-carbon projects and the importance of vessel utilization and milestone billing in converting backlog into revenue; see Ownership of McDermott Company for corporate context: Ownership of McDermott Company

How McDermott monetizes project execution and assets

McDermott turns awarded EPC and installation scopes into cash by progressing engineering to procurement and construction milestones, billing per contract terms, and leveraging vessel-day rates and service fees; backlog concentration and contract type determine margin outcomes.

• Large EPC contracts (lump-sum and cost-plus) drive most revenue
• Vessel operations and specialized engineering services provide secondary income
• Monetization via milestone billing, reimbursable invoicing, and embedded daily rates
• Backlog size, regional award mix, and contract type strongest revenue levers

McDermott Company sustains revenue by delivering engineering, procurement, construction and installation (EPCI) projects for offshore oil and gas and energy-transition customers, leveraging scale, specialized subsea fleets, and long-term client relationships while facing execution and capital-intensity risks in 2025 – 2026.

What Supports the Model

Scale in large EPC contractor oil and gas projects, access to long-term contracts with National Oil Companies, and a diversified 2025 backlog near $10.1 billion give predictable cash flow and bargaining power on major offshore awards.

Key Assets or Capabilities

Proprietary engineering for FPSO and topside systems, global subsea installation vessels, and a multidisciplinary project management organization underpin McDermott business model and its ability to win offshore engineering and construction awards.

Dependencies or Constraints

Revenue depends on large fixed-price EPC contracts, concentrated regional capex cycles (Middle East, North Sea), and availability of skilled engineering and fleet capacity; single-project cost overruns can erase profits.

How Durable the Model Looks

Model appears resilient through 2026 due to sustained global energy security spending and a pivot to LNG and energy-transition projects, but durability is fragile around execution risks and fleet capital needs.

If needed, the clearest short take: McDermott makes money by winning and executing large EPCI contracts where scale and engineering depth create high barriers, but profitability hinges on disciplined bidding and tight execution control.

What Keeps the Business Model Working

McDermott company monetizes offshore engineering and construction through fixed – price and reimbursable EPC contracts, subsea installation services, and growing LNG and energy-transition work; cost overruns and capital intensity remain the primary threats.

• Barrier to entry from specialized FPSO and subsea capabilities
• Global fleet and engineering IP that win large projects
• Concentration on major regional capex cycles and fixed-price exposure
• Resilient in demand but exposed to execution and cost-overrun risk
