MARIC’s new ammonia-ready bulker wins DNV AiP

Norwegian classification society DNV has granted approval in principle (AiP) to the Marine Design and Research Institute of China (MARIC) for its groundbreaking wide beam ammonia-ready Kamsarmax bulk carrier. This vessel, designed to enhance cargo capacity while minimizing environmental impact, features a shallow draft for versatile port access and is equipped for wind-assisted propulsion. The approval marks a significant step towards sustainable shipping solutions.

Innovative Design and Environmental Commitment

The newly designed Kamsarmax bulk carrier measures 229 meters in length and boasts an increased beam of 38 meters, optimizing cargo volume without compromising draft. Its hull structure is reinforced to support the vessel’s operational demands, and it includes designated space for retrofitting ammonia tanks and systems. With a tank capacity of 4,500 cubic meters, the ship can travel over 15,000 nautical miles at design speed when fueled by ammonia.

Zhu Jianzhang, Vice President of MARIC, expressed pride in the collaboration with DNV, emphasizing their commitment to pioneering green shipping technologies. “This partnership underscores our dedication to advancing the maritime industry’s transition to a low-carbon future,” he stated. The collaboration aims to address the technical and operational challenges of using ammonia as a marine fuel, striving to create a solution that aligns with global decarbonization goals.

Øyvind Pettersen, Head of Technical Centre China at DNV Maritime, highlighted the significance of this AiP, noting that it represents a milestone in the journey towards adopting ammonia as a marine fuel. He acknowledged the need for innovation and a strong focus on safety to realize the full potential of ammonia in shipping. Pettersen stated, “This collaboration will strengthen confidence in new fuels and further shipping’s journey toward a more sustainable tomorrow.”

Ammonia’s Role in Sustainable Shipping

Green ammonia is increasingly recognized as a viable candidate for climate-neutral fuel, particularly when produced from renewable energy sources. In 2024, the first orders for ammonia-fueled vessels were placed, primarily within the bulk carrier segment, signaling a growing acceptance of ammonia in the alternative fuel market. However, a recent study from Chalmers University of Technology in Sweden cautioned that the push for ammonia in shipping could lead to new environmental challenges, as various issues are associated with ammonia use.

As the maritime industry seeks to reduce greenhouse gas emissions, the development of ammonia-ready vessels like MARIC’s Kamsarmax bulk carrier represents a crucial step forward. The collaboration between DNV and MARIC not only showcases innovative design but also reflects a broader commitment to sustainable practices in shipping, paving the way for a cleaner, more efficient future in maritime transport.
