French organisation Gaztransport & Technigaz (GTT) will design the fuel tanks for five LNG-fueled container vessels (15,000 CTU each) based on its Mark III, ammonia-ready membrane containment system. Vessel deliveries are scheduled for late 2023 to early 2024.

Last month brought news of "the world’s first ammonia ready vessel.” According to an American Bureau of Shipping (ABS) press release, the vessel, currently under construction in China, will comply “with the ABS Ammonia Ready Level 1 requirements, indicating it is designed to be converted to run on ammonia in the future.” When completed, the 274-meter ship (and possibly two others of identical design) will join the fleet of Avin International.
