GTT and Hudong-Zhonghua Shipbuilding have launched a joint innovation project to optimise the design and performance of LNG bunkering vessels. The initiative aims to enhance operational efficiency and reduce operating costs by integrating advanced technologies and design improvements.
At the core of this project is the increase of the effective pressure in LNG tanks using GTT’s Mark III Flex membrane containment system. While the current industry standard sits at 0.7 barg, the partnership will enable a design pressure of 1 barg, leveraging on various approvals already received from Class Societies for this pressure.
This breakthrough will offer operators several key advantages:
· Extended operational flexibility: The ability to load LNG at higher temperatures as well as the possibility to speed up the LNG delivery.
· Improved energy efficiency: The reduction in the vessel’s electrical power consumption, particularly during stand-by periods, thanks to a lower use of its subcooler.
· Regulatory compliance anticipated: The new design anticipates evolving environmental regulations, including AFNIR recommendations on cold-ironing, thanks to a significant increase in holding time.
This partnership will also evaluate the technical feasibility of increasing the design pressure up to 2 barg. This collaboration reflects the shared commitment of GTT and Hudong-Zhonghua Shipbuilding to drive continuous innovation and support the maritime industry’s energy transition.
