Hd Hyundai Heavy Industries has completed construction of the first ocean-going vessels designed to run on ammonia fuel, marking a significant advance in the shipping sector’s efforts to reduce emissions and develop the ammonia supply chain.
HD Hyundai Heavy Industries says it has finished building what it describes as the world’s first ocean-going vessels designed to run on ammonia fuel, a development that underlines the maritime sector’s push to cut emissions from deep-sea shipping.
The South Korean shipbuilder held a naming ceremony at its Ulsan yard for two 46,000-cubic-metre mid-sized gas carriers, Antwerpen and Arlon, built for Exmar LPG France, the Belgian shipping group Exmar’s subsidiary. The ships are the first pair in a four-vessel series ordered in 2023 and 2024.
According to HD Hyundai, the vessels are fitted with dual-fuel propulsion engines and are scheduled for delivery in May and late July after final outfitting work is completed. Exmar said the project has been under development for more than three and a half years and reflects close cooperation between the shipowner and the yard.
The ships measure 190 metres in length, 30.4 metres in beam and 18.8 metres in height. Exmar said they carry 45,000 cubic metres in cargo tanks, plus two 500 cubic metre deck tanks, and that the design was adjusted with a longer hull and slightly wider beam to increase cargo intake versus a standard layout.
Beyond the headline of a first-of-its-kind vessel, the project is also notable for what it signals about the emerging ammonia value chain. Ammonia is being explored as a marine fuel because it can help eliminate carbon dioxide emissions at point of use, although its wider adoption depends on solving challenges around safety, engine performance, fuel availability and upstream production with low-carbon inputs.
For industrial decarbonisation stakeholders, the order points to a broader shift: shipping owners are beginning to place firm bets on alternative fuels that move beyond compliance and into commercial deployment. The question now is less whether ammonia can be engineered into oceangoing tonnage, and more how quickly the surrounding infrastructure and fuel supply can scale to support it.

The company held a naming ceremony at its Ulsan shipyard for two 46,000-cubic-meter mid-sized gas carriers equipped with dual-fuel engines. The vessels, named ‘Antwerpen’ and ‘Arlon’ after Belgian cities, are the first two of four ammonia-powered mid-sized gas carriers ordered by Exmar LPG France, a subsidiary of Belgian shipping company Exmar, in 2023 and 2024. The ships are scheduled for delivery in May and late July, respectively, following final outfitting. Each vessel measures 190 meters in length, 30.4 meters in width, and 18.8 meters in height, and is equipped with three cargo tanks designed and built using HHI’s proprietary technology, enabling the safe transport of liquefied gas cargoes such as ammonia and liquefied petroleum gas (LPG).

The 46,000 m³ vessels named ANTWERPEN and ARLON — comprising 45,000 m³ cargo tanks and two 500 m³ deck tanks — are purpose-built in close cooperation with the yard. Through a deliberate extension of the vessel’s length by 10 metres and a slight increase in beam, we achieved a meaningfully higher cargo intake compared to the standard design.
