The Global FLNG Revolution: How Floating LNG Capacity Will Transform Energy Markets by 2030
The global liquefied natural gas (LNG) industry is undergoing a significant transformation with floating LNG (FLNG) technology emerging as a game-changing solution. According to recent industry analysis from Rystad Energy, global floating LNG capacity is set to skyrocket by 2030, reaching an impressive 42 million tonnes per annum (Mtpa), up from just 14.1 Mtpa in 2024. This remarkable growth trajectory is expected to continue, with capacity potentially reaching 55 Mtpa by 2035—nearly quadrupling current levels.
What is Driving the Surge in Floating LNG Capacity?
FLNG technology represents a fundamental shift in how natural gas resources are developed and monetized. Unlike traditional LNG facilities that require extensive onshore infrastructure, FLNG units combine extraction, processing, liquefaction, storage, and offloading capabilities on a single floating vessel. This revolutionary approach is gaining momentum for several compelling reasons.
The Evolution of FLNG Technology
FLNG technology has matured significantly over the past decade, overcoming initial technical and operational challenges that once limited its adoption. The industry has demonstrated impressive progress in optimizing these floating facilities:
- Terminals commissioned before 2024 have achieved an average utilization rate of 86.5% in 2024 and 76% to date in 2025
- These utilization rates now rival those of conventional onshore LNG facilities
- Operational reliability has improved dramatically across various marine environments
- Engineering advancements have addressed early design limitations and performance issues
As Kaushal Ramesh, Vice President of Gas & LNG Research at Rystad Energy, explains: "FLNG has come a long way in less than a decade. The only real roadblocks were early teething issues that come with any new technology, as seen with projects like Shell's Prelude, which faced cost overruns and unstable output. But since then, the industry has matured significantly, including Prelude itself. Utilization rates are improving, the technology is proving reliable across a range of environments, and the economics are starting to make more sense."
Economic Advantages Driving Adoption
The economic case for FLNG has strengthened considerably as the technology has matured:
- Capital costs have declined significantly through standardization and experience
- Project timelines have compressed from approximately 4.5 years for onshore facilities to just 3 years for FLNG newbuilds
- Financing risks are reduced due to shorter construction periods and modular development approaches
- Previously stranded gas resources can now be economically developed without costly pipeline infrastructure
- Asset mobility provides a crucial hedge against resource depletion and changing market conditions
How Have FLNG Projects Overcome Their Initial Challenges?
Early FLNG projects encountered significant obstacles that threatened the viability of the technology. Shell's Prelude FLNG in Australia became a cautionary tale, with costs ballooning to approximately $2,114 per tonne for liquefaction alone. The project also experienced unstable output and operational difficulties that dampened industry enthusiasm.
Learning From Early Mistakes
The industry has learned valuable lessons from these pioneering projects:

These improvements have transformed FLNG from an experimental concept to a mainstream development option. The technological maturation process, while challenging, has created a foundation for the current surge in FLNG adoption globally.
Cost Reduction Strategies
Modern FLNG developments have implemented several strategies to dramatically reduce costs:
- Standardized Designs: Replicating successful configurations rather than reinventing each project
- Modular Construction: Building components in specialized shipyards before final assembly
- Vessel Conversions: Repurposing existing maritime assets rather than building from scratch
- Supply Chain Optimization: Developing dedicated supplier networks for specialized components
- Scale Efficiencies: Applying learnings across multiple projects within company portfolios
These approaches have created a virtuous cycle of improvement, where each successful project provides insights that benefit future developments.
What Makes FLNG More Cost-Effective Than Traditional LNG?
The economics of FLNG have improved dramatically, making it increasingly competitive with—and in some cases superior to—conventional onshore LNG facilities.
Declining Capital Expenditure
The cost structure of FLNG projects has evolved significantly, as evidenced by recent developments:
- Proposed developments along the US Gulf Coast now average around $1,054 per tonne
- The Delfin FLNG project costs approximately $1,134 per tonne
- Coral South FLNG in Mozambique reports comparable liquefaction costs of $1,062 per tonne
These figures represent a significant improvement from early projects and demonstrate that floating LNG capacity is set to skyrocket by 2030 as cost-competitiveness has entered a new era. The cost reductions stem from standardized designs, improved construction techniques, and operational efficiencies that weren't available to pioneer projects.
Vessel Conversion Advantages
One of the most cost-effective approaches involves converting existing vessels, which has yielded impressive results:
- Tortue/Ahmeyim FLNG achieved capex levels of approximately $640 per tonne
- Cameroon FLNG reduced costs to around $500 per tonne
- Southern Energy's FLNG MK II reports costs of about $630 per tonne
These vessel conversion projects demonstrate that FLNG technology can be deployed at significantly lower costs than previously thought possible, opening up development opportunities for smaller gas fields that would otherwise remain stranded.
These conversions leverage Moss-type LNG carriers with modular spherical tank designs, which simplify the integration of prefabricated liquefaction modules. With numerous Moss-type LNG tankers approaching retirement in coming years, this approach offers significant expansion potential for lower-cost FLNG solutions.

FAQ: Understanding the FLNG Revolution
What exactly is FLNG technology?
Floating Liquefied Natural Gas (FLNG) refers to offshore facilities that extract, process, liquefy, store, and transfer natural gas entirely at sea. These floating facilities eliminate the need for pipelines to shore, gas processing plants, and onshore LNG export terminals, allowing for the development of offshore gas fields that would otherwise be economically unfeasible.
How does FLNG compare to traditional LNG in terms of environmental impact?
FLNG facilities generally have a smaller physical footprint than equivalent onshore infrastructure. They eliminate the need for long pipelines and extensive onshore construction, potentially reducing habitat disruption. However, they still involve fossil fuel production and face similar challenges regarding methane emissions and energy consumption for the liquefaction process.
What are the main financial risks associated with FLNG projects?
Key financial risks include cost overruns during construction (though these have decreased as the technology matures), operational disruptions due to weather or technical issues, market price volatility affecting revenue streams, and potential stranded asset risk as the world transitions toward lower-carbon energy sources.
How does FLNG fit into the energy transition?
FLNG can play a transitional role in the shift toward cleaner energy systems. Natural gas produces fewer emissions than coal when burned for electricity, and FLNG enables access to previously stranded gas resources. Some newer FLNG designs are also being developed with potential future conversion to handle hydrogen or ammonia production, aligning with longer-term decarbonization goals.
What makes vessel conversion more cost-effective than newbuild FLNG?
