French technological containment specialist Gaztransport & Technigaz (GTT) and China’s Hudong-Zhonghua Shipbuilding have initiated a joint innovation project to optimize the design and performance of LNG bunkering vessels.
According to GTT, this joint project aims to enhance operational efficiency and reduce operating costs by integrating advanced technologies and design improvements.
The partners intend to increase the effective pressure in LNG tanks to 1 bar gauge (barg) from the current industry standard of 0.7 barg using GTT’s Mark III Flex membrane containment system and leveraging previous approvals from class societies for this pressure.
Advantages expected from this design include:
GTT stated that this partnership will also evaluate the technical feasibility of increasing the design pressure to 2 barg.
The French company recently signed two agreements with South Korean shipbuilder HD Hyundai Heavy Industries (HD HHI) to optimize the performance of LNG carriers.
Specifically, the partnership seeks to improve membrane-tank integration to enhance onboard ergonomics and LNG carriers’ operational performance.
