DNV awards AiP for new ammonia-ready bulk carrier

The Marine Design and Research Institute of China (MARIC) has achieved a significant milestone by securing approval in principle (AiP) from DNV for a groundbreaking ammonia-ready Kamsarmax bulk carrier. This innovative vessel, designed with a shallow draft for versatile port access, is also equipped with a wind-assisted propulsion system (WAPS), marking a step forward in sustainable shipping technology.

Innovative Design for Sustainable Shipping

Measuring 229 meters in length and featuring an expanded beam of 38 meters, the new bulk carrier design is optimized to maximize cargo capacity while maintaining the same draft. The hull structure has been reinforced to support the vessel’s operational needs, and provisions have been made for the future installation of ammonia tanks and related systems. This design allows the ship to travel over 15,000 nautical miles at its designated speed while being powered by ammonia fuel.

Zhu Jianzhang, vice president of MARIC, expressed pride in the collaboration with DNV, emphasizing the importance of this partnership in advancing green shipping technologies. “This initiative highlights our commitment to facilitating the maritime industry’s transition to a low-carbon future,” he stated. “By addressing the technical and operational challenges associated with ammonia as a marine fuel, we aim to deliver a state-of-the-art solution that aligns with global decarbonization objectives.” This collaboration is seen as a pivotal step in setting new standards for clean, efficient, and commercially viable bulk carriers.

Commitment to Safety and Innovation

Øyvind Pettersen, head of the China Technical Centre at DNV Maritime, remarked on the significance of awarding MARIC this AiP, noting it as a crucial advancement in the use of ammonia as a marine fuel. He stressed that realizing the full potential of ammonia requires both innovation and a strong focus on safety. “Our partnership with MARIC is vital as we build on the industry’s most advanced classification standards,” Pettersen added. “This AiP will enhance confidence in new fuels and propel the shipping industry towards a more sustainable future.”

DNV has been at the forefront of developing classification rules for ammonia-fueled vessels, with the first edition published in 2021, followed by updates in 2022 and 2023. These updates include the Gas Fuelled Ammonia class notation, which provides shipowners with the necessary guidelines for constructing ships that will utilize ammonia propulsion. Additionally, DNV has released a white paper titled Safe Introduction of Alternative Fuels – Focus on Ammonia and Hydrogen as Ship Fuels, offering valuable insights for shipowners navigating the evolving regulatory landscape surrounding alternative fuels.
