McDermott has secured a significant Master Services Agreement (MSA) with Monkey Island LNG in Louisiana. This contract supports front-end engineering and planning for a major proposed LNG export development. Furthermore, it reflects the company’s strength in large-scale energy infrastructure delivery.
Project Overview
MSA Awarded To McDermott for Monkey Island LNG
Initial Capacity 15.6 MTPA (3 trains, 5.2 MTPA each)
Potential Expansion Up to 26 MTPA (adding two more trains)
Technology ConocoPhillips cascade process, modular LNG trains
Timeline Engineering starts 2026, production in early 2030s
Strategic Context Part of Louisiana’s growing LNG export push
Services McDermott Will be Offering
Under this MSA, McDermott will provide engineering, execution planning, and pricing services. Their expertise will guide the initial phase of the Cameron Parish facility. This phase includes three LNG trains, each with a 5.2 million tonnes-per-annum (MTPA) capacity. In total, that equates to a combined 15.6 MTPA output. Moreover, future expansion could add two more trains. Such expansion would raise total capacity to 26 MTPA, placing the project among North America’s largest private energy investments, alongside developments like the $5.1 billion Woodfibre LNG project in British Columbia, which recently marked a major construction milestone.
Innovative Design and Technology
Monkey Island LNG will deploy the ConocoPhillips Optimized Cascade Process. To support this, the project will use McDermott’s modular LNG train design. This design reportedly delivers up to 60 percent more LNG per acre than comparable projects. Thus, it effectively lowers site footprint, cost, and project risk.
Timeline and Execution Strategy
McDermott’s Houston office will lead engineering efforts, with backup from its Gurugram, India, team. Engineering and permitting are slated to begin in 2026. Importantly, the first LNG exports are expected in the early 2030s. Additionally, this arrangement may evolve into a full EPC (engineering, procurement, and construction) contract, contingent on financing.
Project Significance
This development reflects a broader trend in US LNG infrastructure growth. Notably, Commonwealth LNG recently selected Technip Energies for its Cameron Parish project. That facility aims for a 9.5 MTPA capacity and targets operations by 2029.
Therefore, McDermott’s role underscores the strategic importance of the Gulf Coast as an expanding LNG export hub. Moreover, it highlights continued investment in American energy infrastructure.
In Conclusion
McDermott’s Master Services Agreement for this Louisiana LNG facility marks a major milestone. It demonstrates the company’s engineering capability and the project’s ambitious scale. With modular design and advanced processes, it promises efficiency and reduced footprint. Meanwhile, the timeline signals strong momentum for US LNG expansion. In summary, this development underscores both innovation and strategic growth in the energy sector.
