GTT Inside, the GTT newsletter
Message from François Michel, CEO of GTT
Since taking up my role as Chief Executive Officer of GTT on 5 January, I have spent my first weeks meeting many of you, our clients and partners across the LNG value chain. These exchanges have been both energising and instructive. They reaffirm my conviction that beyond technology, our industry is built on trust and long-term relationships.
They have also taken place at a time when, despite geopolitical uncertainty, LNG fundamentals remain strong. Record investment decisions for new liquefaction projects provide greater visibility for our industry and reinforcing sustained momentum.
In this context, I am pleased to introduce this new edition of GTT Inside, highlighting the latest innovations in our membrane containment technologies. These developments reflect our ambition to push technological boundaries, simplify shipyard operations, and support ship-owners throughout the lifecycle of their vessels.
I look forward to engaging with you in the coming months to address the challenges ahead. Through close collaboration and shared commitment, we will continue to advance our industry and shape a more sustainable future together.

PIONEERING PROGRESS
Expanding the Applicability of Membrane FLNG Designs Through Continuous Innovation
The global energy market is increasingly demanding flexible, robust, and cost-efficient LNG infrastructure. Thanks to decades of continuous R&D, GTT’s membrane technologies have become the benchmark for the most efficient and reliable containment solutions for FLNG applications. To date, four FLNG units equipped with GTT technologies are in operation worldwide, with three additional units currently under construction, including two featuring a 1-row architecture, demonstrating the maturity and strong industrial track record of these solutions.
SUSTAINABILITY CORNER
Reducing GHG Emissions in LNG Containment Systems
As regulations tighten to protect the stratospheric ozone layer and reduce greenhouse gas (GHG) emissions from maritime transport, GTT focuses on enhancing the environmental performance of LNG cryogenic containment systems while maintaining the highest technological and safety standards.
By far, the primary source of GHG emissions associated with LNG cryogenic containment systems is excess boil-off gas (BOG). GTT’s advanced containment technologies and associated services are specifically designed to minimise BOG generation and facilitate its efficient capture and reliquefaction, thereby supporting the Group’s commitment to bringing to market solutions that reduce carbon footprint.
TECH IN FOCUS
Design Improvements on LNG Carrier Cargo Handling Systems: Reliability, Safety, and Operational Flexibility by Design
At GTT, incremental engineering refinements are a catalyst for tangible value at sea. Building on operational feedback from vessels in service, we have developed a series of improvements to LNG Carrier (LNGC) cargo handling systems that strengthen reliability, safety and operational flexibility, without altering the overall architecture.
Three optimisations are now available to shipyards and ship-owners: an optimised pump tower design with tubular cable way; a top filling pipe designed to limit stratification and rollover risk; and rupture disks offering passive protection against accidental insulation‑space overpressure.
ACROSS THE LIFECYCLE
Ensuring Safety and Performance of Liquefied Gas Units
With more than 60 years of field experience, GTT’s expertise extends well beyond engineering and design. It also encompasses highly specialised know-how that supports clients and stakeholders during one of the most critical phases in a vessel’s lifecycle: initial LNG operations.
During this stage, all equipment, including compressors, heaters and insulation, are tested under real conditions, through the full spectrum of operations the vessel will perform throughout its service life: insulation cool-down, tank loading and unloading, and cargo transfers between tanks. At this stage, design assumptions are confronted with operational reality, and experience proves decisive.
