LNG Consulting
A&A Consulting Services for LNG Infrastructure, Floating LNG Systems, and Process Engineering — Onshore Terminals Through Offshore Installation and Detailed Process Design — Worldwide
Assign your company's LNG project development and engineering challenges to A&A, and let the high-level, seasoned LNG consultants of the A&A Consulting Team put decades of hands-on LNG industry experience to work for you, around the world.
Global LNG trade hit a record 437 million tonnes in 2025, up 6.3% year-over-year, and Shell's 2026 LNG Outlook projects demand growing to nearly 700 million tonnes a year by 2050. U.S. LNG exports alone reached 17.4 billion cubic feet per day in the first half of 2026, up 23% year-over-year, as Golden Pass LNG shipped its first cargo as the ninth U.S. export terminal. Meeting that growth requires two distinct engineering disciplines working in concert: the onshore and offshore infrastructure that receives, stores, and ships LNG — including a floating fleet of 56 FSRUs in operation worldwide and floating liquefaction (FLNG) capacity approaching 22 million tonnes per annum in 2026 — and the process engineering that turns raw gas into LNG and back again, safely and to specification.
Avasthi & Associates, Inc. (A&A) is an independent LNG and offshore engineering consulting firm. A&A does not sell LNG process licenses, vessels, shipyard construction, or EPC services, and holds no equity in any terminal, vessel, or project — our only business is expert technical consulting, which means A&A's LNG recommendations are never influenced by a stake in any particular vendor, shipyard, licensor, or technology.
A&A's LNG Consulting Services
A&A's LNG practice is organized into two consulting services, each with its own dedicated page describing A&A's methodology, project experience, and deliverables in depth:
1. LNG Infrastructure and Floating LNG Consulting
Onshore LNG terminal site selection and infrastructure development, and offshore floating system (FLNG, FSRU, FSU) concept, design, and project development — through fabrication, tow, installation, and commissioning. Covers terminal siting, storage tank technology selection, FSRU/FSU conversion consulting, floating-system engineering and technology selection, and floating LNG system safety, construction, and installation.
2. LNG Process Engineering Consulting Services
Process concept development, FEED, and detailed engineering support across the full LNG value chain — gas processing/pre-treatment, liquefaction, storage & handling, and regasification. Covers process technology and licensor screening, process safety (PHA/HAZOP/LOPA) and regulatory support, commissioning and start-up support, and LNG value-chain training.
How A&A's LNG Services Fit Together
The two disciplines above map to the two engineering teams a real LNG project actually runs, though A&A clients engage A&A at whichever point their project needs support:
• LNG Infrastructure and Floating LNG Consulting: the marine, structural, and offshore engineering scope — where the terminal or vessel sits, what it's built of, and how it gets installed
• LNG Process Engineering Consulting Services: the process engineering scope inside that terminal or vessel — how gas is treated, liquefied, stored, and regasified, and how that process is proven safe
Why LNG Companies Choose A&A
• Full-chain LNG expertise: decades of combined hands-on experience across onshore terminals, floating systems, and LNG process engineering, from concept through commissioning
• Independent: no LNG process license, vessel, shipyard, or EPC business to protect — A&A's advice is unconflicted
• Worldwide project experience: LNG projects across Africa, the Middle East, Asia-Pacific, and the Americas, from first-of-a-kind floating systems to major U.S. export terminals
What A&A Delivers
An LNG engagement with the A&A Consulting Team is built around the practical decisions your company needs to make, including, but not limited to:
• An onshore terminal site-selection study, or an FLNG/FSRU/FSU concept-selection and project development study
• A process concept selection and technology/licensor ranking study, or a FEED- or detailed-engineering-stage process review
• HAZID/HAZOP/PHA/LOPA study reports and an operation safety case
• Independent, vendor-neutral technical due diligence for investors and lenders considering an LNG investment
Frequently Asked Questions
Which A&A LNG service is the right starting point for our project?
It depends on what your project needs. A new terminal site, a floating system (FLNG/FSRU/FSU) concept or conversion, or offshore installation planning typically starts with LNG Infrastructure and Floating LNG Consulting. A process concept, FEED or detailed-engineering support, a process safety review, or commissioning support typically starts with LNG Process Engineering Consulting Services. Most projects need both, and A&A's consultants work across both disciplines.
Can A&A support both the infrastructure and process engineering scope on the same project?
Yes. A&A's LNG consultants regularly work across both disciplines on the same project, and can be engaged for either service independently or together, depending on what stage your project is at and what scope you already have covered in-house or through other consultants.
Does A&A provide independent second-opinion reviews of LNG work already completed?
Yes, on both the infrastructure/floating-system side and the process engineering side. A&A regularly reviews and assesses work already performed by a client's own in-house team, or by another consulting or service company — a common engagement for a client seeking an independent check before a major investment decision.
Does A&A sell LNG technology, vessels, or hold equity in any LNG project?
No. A&A is an independent LNG and offshore engineering consulting firm. A&A does not sell LNG process licenses, vessels, shipyard construction, or EPC services, and holds no equity in any terminal, vessel, or project, so A&A's recommendations are never influenced by a stake in any particular vendor, shipyard, licensor, or technology.
Whether you are developing a new onshore terminal, evaluating a floating LNG system, or need process engineering support from concept through commissioning, the A&A Consulting Team can help you move your LNG project forward.
