HD Hyundai Heavy Industries wins DNV AiP for ammonia DF large container vessel

Classification society DNV on Wednesday (30 November) said it has awarded an Approval in Principle (AiP) to HD Hyundai Heavy Industries (HD HHI) for its 15K TEU ammonia dual-fuelled container vessel design.

DNV said the milestone follows the successful completion of a joint development project aimed at addressing the challenges associated with using ammonia as a marine fuel.

“The project focused on developing designs to enhance safety, including an optimised ammonia tank design, advanced fire safety systems, enhanced ammonia release mitigation system and boil-off gas (BOG) handling systems,” it said in a statement.

“These innovations could play an important role in building confidence in the safe and efficient use of ammonia as a marine fuel.”

On container ships, where the upper deck is a safe working zone, DNV said an ammonia leak could pose a serious risk. This means, establishing safety design criteria to manage these risks is crucial for the wider commercialization of ammonia-fueled ships.

To this end, fuel pipe leakage scenarios were defined and quantitatively analysed through gas dispersion analyses. Consequently, it was confirmed that, with conventional systems, foreseeable small leakages occurring at connections within the ammonia piping system can form toxic areas with dangerous ammonia concentrations throughout the entire weather deck, highlighting the need for effective mitigation measures.

The result showed that hazardous areas were significantly reduced by the enhanced ammonia release mitigation system, enabling not only safer enclosed spaces but also safer working areas across the entire weather deck of the vessel.

Seung-ho Jeon, SEVP, CTO of HD HHI, said: “The AiP reflects HD HHI’s dedication to developing sustainable, innovative solutions like ammonia-fuelled vessels, which will play a key role in reducing emissions and shaping the future of shipping.”

Vidar Dolonen, DNV Regional Manager Korea and Japan, said: “This AiP highlights the importance of safety in moving the maritime industry along the path to decarbonization.”

“There are many aspects to building out zero carbon fuels in shipping, and it’s essential that we have them all in place for ammonia to truly establish itself in the marine fuel market.”

“But with new technological solutions, alongside rigorous safety procedures, ammonia reach its full potential as one of the most promising green fuels. DNV is proud to support these advancements from HD HHI as we continue on this journey to an even more sustainable maritime industry.”

EXMAR’s “ANTWERPEN” completes first commercial voyage using ammonia bunker fuel

Belgian shipowner EXMAR on Monday (20 July) announced the successful completion of gas carrier ANTWERPEN’s first commercial voyage using ammonia as a marine fuel.

During its voyage from China to India, the vessel achieved ammonia dual-fuel operation fully in line with our expectations and design, demonstrating that the technology works in commercial service.

“Together with our partners, we continue to fine-tune the systems as we build on this outstanding achievement. We are proud of our crew for their excellent pioneering work,” the company said in a social media post.

Developed in close collaboration with HD Hyundai Heavy Industries, WinGD, Nord Gas Solutions (formerly Wärtsilä Gas Solutions), and Lloyd’s Register, ANTWERPEN is capable of carrying up to 46,000 m³ of ammonia or LPG and trading with close to zero emissions when using low-carbon ammonia fuel.

The vessel meets and exceeds current IMO emissions reduction targets, reducing greenhouse gases by up to 90% compared to conventional ships.

Manifold Times previously reported ANTWERPEN participated in a pipe-to-ship (PTS) ammonia bunkering operation in Ulsan Port.

The operation was carried out by Lotte Fine Chemical Co Ltd with 600 metric tonnes (mt) of green ammonia (NH3) supplied to ANTWERPEN.

KR, HD Hyundai tap first ammonia dual-fuel sea trial to develop vessel operating standards

Korean Register (KR) on Tuesday (14 July) said it is collaborating with HD Hyundai Heavy Industries (HHI) to establish a domestic operating environment for ammonia-fuelled vessels under the Ministry of Oceans and Fisheries’ Green Shipping Corridor Construction Support Project.

The initiative supports the development of ammonia as one of the most promising next-generation marine fuels.

HHI recently conducted a sea trial of Korea’s first ammonia dual-fuel propulsion vessel. The trial generated operational data on the vessel’s fuel supply system and engine, which will provide a valuable technical foundation for KR’s future development of domestic guidelines for environmentally friendly vessel operations and supporting wider maritime decarbonisation efforts.

A spokesperson for HD Hyundai, said: “Drawing on our group’s R&D capabilities and on-site technical expertise, we have made meaningful progress in advancing the application of ammonia as a marine fuel. We expect this to help enhance a sustainable maritime ecosystem while strengthening the competitiveness of Korea’s shipbuilding industry.”

Kim Daeheon, Executive Vice President of KR’s R&D Division, added: “The close collaboration between KR and HD Hyundai has enabled us to build the technical foundation for introducing ammonia-fueled vessels in Korea. We will continue to drive national projects forward together with HD Hyundai and establish technical standards befitting the era of Green Shipping Corridors.”

Sales of marine fuel at Singapore port increased by 1.6% on year in June 2026, according to data from the Maritime and Port Authority of Singapore (MPA).

In total, 4.67 million metric tonnes (mt) (exact 4,669,100 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in June, up from 4.59 million mt (4,594,700 mt) recorded during the similar month in 2025.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in June (against on year) recorded respectively 2.03 million mt (+19.4% from 1.70 million mt), 2.20 million mt (-4.8% from 2.31 million mt), zero (-100% from 1,900 mt), 1,900 mt (-57.8% from 4,500 mt) and zero (from zero).
