In South Korea, EXMAR names world’s first ammonia-fueled ocean-going ships

April 15, 2026 |

In South Korea, Belgian shipping company EXMAR has named the world’s first ocean-going vessels capable of running on ammonia as fuel. The two 46,000 cubic meter mid-size gas carriers, christened Antwerpen and Arlon, are the culmination of a joint development program with HD Hyundai launched three and a half years ago.

The ships can cut CO2 emissions by up to 90% during navigation and draw fuel directly from their cargo tanks, giving operators flexibility conventional vessels cannot match. Development involved HD Hyundai, Wärtsilä, WinGD, and Lloyd’s Register, with propulsion systems logging extensive test hours before delivery.

EXMAR worked with Lloyd’s Register and maritime regulators to advance IMO guidelines enabling ammonia as fuel on gas carriers, a step the company says benefits the entire industry.

The namings follow four decades of EXMAR operating ammonia and LPG carriers.
