Bunker Vessel
As the shipping industry moves toward decarbonisation, LNG has emerged as a key transition fuel.
At the heart of this transformation, LNG Bunker Vessels (LBVs) play a critical role in ensuring flexible, safe, and efficient fuel supply.
To address these challenges, GTT develops next-generation membrane containment solutions designed to optimise operations and anticipate future market developments.
Proven expertise driving performance
With over 60 years of experience in membrane technologies, GTT equips its LNG bunker vessels with Mark III Flex technology, a global benchmark for reliability and efficiency.
Beyond technology, GTT supports its clients throughout the entire vessel lifecycle:
- crew training
- operational support
- specialised technical services
This comprehensive approach ensures long-term, safe, and efficient operations.
Maximising every cubic meter
GTT solutions are designed to make the most of available space on board, without compromising safety or performance.
- Compatible with all tank types
- Up to 20% more efficient space utilisation compared to alternative technologies
- Suitable for all vessel sizes (from 5,000 to 25,000 m³)
The result: optimised cargo capacity and improved operational profitability.
Delivering operational excellence
Engineered to meet the highest operational standards, membrane-equipped LNG bunker vessels offer:
- Very low boil-off rate (BOR), reducing costs during idle periods
- Optimised design pressure (1.0 barg)
- Low-pressure LNG delivery
- Full operational flexibility with no filling restrictions worldwide
Their design also enables:
- fast and safe bunkering operations
- high maneuverability
- compact configurations suited to constrained port environments
They fully support routine operations such as gassing-up and cooling-down procedures.
Solutions designed for the future
In a rapidly evolving regulatory and environmental landscape, GTT develops vessels that are built to last.
- Ammonia-ready containment systems
- Reduced emissions across the entire lifecycle
- Adaptability to future environmental regulations
- Integration of hybrid solutions (e.g. Hybrid-Electric)
A future-ready approach that secures long-term investments.
