Two ammonia-ready vessels - the CMA CGM Masai Mara and the ALS Ceres - were delivered this May. Both are the first in a series of six containerships contracted to be built at different Chinese shipyards.

This week we explore a trio of announcements out of China:

1. The ammonia-ready vessel Kriti Future has been delivered to owners Avin International.

2. Höegh Autoliners has contracted China Merchants Heavy Industry to build at least four of their new ammonia-ready vessel design: the Aurora-class car carrier. The new builds will meet requirements for DNV GL's methanol and ammonia-ready notation guides.

3. And Swiss-based shipping giant MSC has placed an order for six ammonia-ready container ships from Dalian Shipbuilding in China. The vessels will be powered by WinGD dual-fuel engines, for which retrofits will be available by 2024/5 to run on methanol and ammonia.

Three separate projects to design a range of ammonia-fueled vessels were announced last week at a shipping industry conference in China. Lloyd's Register has granted Approval in Principle (AiP) for the design of a 180,000 ton bulk carrier. ABS announced a project to "produce designs for an ammonia-fueled Chittagongmax container carrier of 2700 TEU capacity." And Lloyd's Register also announced a project for "an ammonia-fuelled 23,000 TEU Ultra-Large Container Ship (ULCS) concept design." All three projects are working with the two-stroke ammonia engine developed by MAN Energy Solutions, and all are led by major shipbuilders in China.
