The Belgium-based gas carrier operator Exmar named the ‘world’s first,’ as it said, ocean-going ammonia dual fuel mid-size gas carriers (MGC) after a three-and-a-half-year joint development program with HD Hyundai.

The two 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, the company achieved a meaningfully higher cargo intake compared to the standard design.

The vessel’s design reflects extensive collaboration through workshops, risk assessments, and rigorous technical reviews, the statement of Exmar reads.

The vessel is the product of a multi-partner development program involving HD Hyundai, HHI-EMD, Wärtsilä Gas Solutions, WinGD, Lloyd’s Register, and Exmar.

According to Exmar, propulsion systems have undergone extensive testing at HD Hyundai’s facilities over a significant number of operating hours.
