World’s First Ammonia Dual-Fuel Midsize Gas Carriers Named In South Korea
Our take

The recent unveiling of the world’s first ammonia dual-fuel midsize gas carriers, ANTWERPEN and ARLON, marks a significant milestone in the shipping industry. Developed through a collaborative initiative with HD Hyundai over the past three and a half years, these vessels represent a pioneering step towards more sustainable maritime operations. As global efforts increasingly focus on reducing carbon emissions and transitioning towards greener energy sources, innovations like these become crucial. They resonate with discussions around the need for strategic investment in the ocean economy, as highlighted in articles such as World Economic Forum: Here's why we need Strategic investment in the Ocean economy..
Ammonia as a fuel source offers a promising alternative to traditional marine fuels. It is not only abundant but also has the potential for zero carbon emissions when burned, assuming it is produced sustainably. This dual-fuel technology aligns with the ongoing discourse surrounding the maritime industry's responsibility to mitigate its environmental impact. The dual-fuel capability allows vessels to switch between ammonia and conventional fuel, providing flexibility while gradually reducing reliance on fossil fuels. This innovation is a practical embodiment of integrating empirical research with real-world applications, a theme prevalent in discussions about the ocean's role in climate change, as noted in Beneath the waves, the ocean holds a hidden record of our planet’s changing climate..
The implications of these advancements extend beyond just technological innovation. They reflect a broader commitment to global collaboration in addressing climate change and fostering ocean stewardship. The joint effort between HD Hyundai and the shipping community signals a willingness to invest in long-term solutions that prioritize environmental health. Moreover, this initiative underscores the importance of integrating scientific research into the development of maritime technologies, ensuring that decision-making is grounded in validated, empirical data. Such collaborative efforts are essential as we navigate the complexities of climate indicators and their impacts on marine ecosystems.
Looking ahead, the introduction of ammonia dual-fuel carriers could serve as a catalyst for further innovations in the shipping industry. As more companies recognize the need to adapt to evolving regulatory landscapes and consumer expectations regarding sustainability, we may witness an acceleration in the adoption of alternative fuels and technologies. The urgency of ocean stewardship cannot be overstated; as stewards of the planet's most vital resource, it is imperative that we pursue solutions that are both impactful and sustainable. The success of these vessels may inspire similar initiatives across various sectors, fostering a culture of innovation and responsibility.
In conclusion, the launch of the ANTWERPEN and ARLON is more than just a technological achievement; it represents a critical step towards a more sustainable maritime industry. It challenges us to contemplate the future of shipping and its role in the broader context of climate action. As we move forward, the question remains: will the maritime industry embrace this momentum and continue to lead in the pursuit of sustainable practices, or will it lag behind as other sectors evolve? The answers to these questions will shape the trajectory of our ocean’s health and the efficacy of our collective climate efforts.


Belgian shipping company EXMAR has named the world’s first ocean-going ammonia dual-fuel midsize gas carriers during a ceremony held in South Korea.
The vessels, ANTWERPEN and ARLON, were developed under a joint programme with HD Hyundai that began more than three and a half years ago.
The company described the naming as an important step for the project and the industry.
Each vessel has a total capacity of 46,000 cubic metres, including 45,000 cubic metre cargo tanks and two 500 cubic metre deck tanks. The ships were built in close cooperation with the South Korean yard.

EXMAR said the vessels were made 10 metres longer with a slight increase in beam, which allows them to carry more cargo than standard designs.
The ships are designed to run on ammonia as a fuel. According to the company, this can cut carbon dioxide emissions by up to 90% during navigation. Using cargo as fuel is also expected to give more flexibility in operations.
The project involved several partners, including HD Hyundai, HHI-EMD, Wärtsilä Gas Solutions, WinGD and Lloyd’s Register.
The propulsion systems were tested over many operating hours at HD Hyundai’s facilities before the vessels were completed.

EXMAR said safety was a key focus during the design process. The vessels were developed through workshops, risk assessments and technical reviews, with input from seafarers who have experience handling ammonia cargo.
The company also worked with Lloyd’s Register and authorities to help develop guidelines for using ammonia as fuel on gas carriers. This work contributed to progress in the International Maritime Organization’s regulatory framework.
Earlier this year, EXMAR carried out its largest ship-to-ship transfer of ammonia so far, adding to its operational experience.
