Industry leaders praise the design’s flexibility and its role in reducing emissions through adaptable technology that supports future fuel conversions.
GTT (Gaztransport & Technigaz) has received an Approval in Principle (AiP) from Lloyd’s Register, a leading global classification society, for its “NH₃-Ready” notation on the Mark III containment system. This certification applies to LNG-fuelled vessels and, more broadly, to the cargo tanks of LNG carriers (LNGCs), very large ethane carriers (VLECs), and bunkering vessels.
Supporting a Flexible and Sustainable Maritime Transition
This innovation provides enhanced fuel flexibility, enabling vessels initially designed for LNG to be converted to ammonia usage at a later stage in their operational life cycle. The AiP underlines GTT’s proactive stance on environmental sustainability, helping the maritime industry adapt to evolving regulatory landscapes and decarbonization targets.
Industry Recognition and Collaboration
David Colson, GTT’s Commercial Vice President, emphasized:
“We are proud to have received this approval from Lloyd’s Register, which once again recognises the flexibility of our technology and our dedication to sustainable innovation. This AiP confirms our ability to support our clients and partners in achieving an effective and responsible energy transition.”
Panos Mitrou, Global Gas Segment Director at Lloyd’s Register, commented:
“This new design shows that by challenging conventional thinking, the maritime industry can effectively transition to cleaner energy sources. By enabling LNG tanks to be converted for ammonia use, carbon emissions are reduced through an innovative solution that helps meet evolving environmental regulations.”
Driving the Maritime Energy Evolution
The “NH₃-Ready” notation demonstrates GTT’s leadership in future-ready containment systems, empowering shipowners and operators with the tools to pivot toward alternative fuels such as ammonia as global decarbonization efforts intensify.
