WinGD, Alfa Laval, ABS and K Shipbuilding to develop ammonia-fuelled tanker design

Swiss marine power company WinGD on Thursday (6 June) said it will work together with Swedish marine technology leader Alfa Laval and the American Bureau of Shipping (ABS) and Korean shipbuilder K Shipbuilding (KSB) on the development of an ammonia-fuelled MR tanker design, under a memorandum of understanding signed in April, which will feature a 6X52DF‑A engine from WinGD.

WinGD will work with KSB to deliver fuel gas system specifications suitable for the vessel application and the selected engine, while Alfa Laval will deliver the detailed documentation for the final fuel gas system design. The design will be reviewed by ABS, with the aim of issuing an approval in principle.

WinGD Vice President R&D, Sebastian Hensel, said: “After early orders for bulk carriers and ammonia carriers, it is encouraging to see that ammonia-fuelled tanker projects are picking up momentum.”

“And even more encouraging that our X‑DF‑A engines are at the heart of many of these projects. Developing full vessel designs that shipowners can adopt easily will only accelerate the transition and we are pleased to be part of the collaboration with KSB in delivering this design.”

Head of Marine Separation & Fuel Supply Systems, Viktor Friberg, Alfa Laval, said: “This MOU signifies a powerful step forward to make ammonia a viable marine fuel. Our proven expertise in handling diverse fuel types, especially methanol and LPG, will be instrumental in designing the new fuel supply system for ammonia.”

“We believe that partnerships are key for the maritime industry to achieve the ambitious decarbonisation targets and support the fuel transition. By working alongside WinGD, ABS and K Shipbuilding, we accelerate this transition and make it safer.”

The X52DF‑A engine is the smallest bore size available in WinGD’s ammonia-fuelled X‑DF‑A series, and the first to be developed. It is expected to have wide application across bulk carriers, tankers and ammonia carriers, and has already been ordered for two ammonia carriers to be delivered in early 2026. 

The X52DF‑A is also the engine design on which four class societies to date, including ABS, have issued approvals in principle for the X‑DF‑A series, assuring shipowners that the engine can be deployed in operation safely.

JDPs and other cooperations have been a cornerstone of WinGD’s ammonia engine developments, with several industry partnerships focused on vessel designs and crew training – supporting both the deployment of ammonia-fuelled engines and the preparedness of the maritime industry to operate them safely

The Maritime and Port Authority of Singapore (MPA) on Thursday (27 March) showcased the prototype of the Maritime Energy Training Facility (METF) Digital Platform, an initiative to help the global maritime workforce access training in the safe handling of alternative marine fuels and new technologies. 

The prototype platform was presented at the “Accelerating Digitalisation and Decarbonisation Conference” at Singapore Maritime Week (SMW 2025) and will be ready by the second half of 2025.

The METF Digital Platform offers maritime companies, seafarers and maritime professionals a systematic and easy way to find relevant courses, register and pay for them.

The platform is currently offered to Singapore-based maritime companies and/or Singapore-registered ships. This would be extended to more companies and stakeholders, including those based overseas, in the next phase.

The prototype is undergoing testing and validation with a group of industry pilot users.

Training progress and certifications received can also be tracked through the platform, helping both companies and individuals monitor compliance with the relevant industry and regulatory standards. By streamlining administrative processes such as training grant eligibility and certification management, the platform reduces the administrative burden on maritime companies and makes training easily accessible for seafarers and maritime professionals.

The METF was first introduced at SMW 2024 as part of Singapore’s efforts to advance maritime decarbonisation and workforce development. Since then, MPA has engaged training providers, shipping companies, and maritime associations to align training standards with industry needs. These efforts have led to the development of the METF Digital Platform, a training management system that simplifies access to training, streamlines certification issuance, and ensures alignment with evolving international standards.

In February 2025, the International Maritime Organization’s Human Element, Training and Watchkeeping Sub-Committee began work to develop interim guidelines for training seafarers in handling alternative marine fuels and new technologies. 

MPA contributed by  proposing draft training guidelines for the safe handling of methanol and ammonia, drawing on Singapore’s experience in competency frameworks, proficiency standards, and training programme development. This included the basic and advanced training for handling of methanol as fuel for maritime personnel by the Singapore Maritime Academy. 

The METF Digital Platform will support the practical implementation of such courses, ensuring seafarers have access to training that meets evolving international safety and operational requirements.

SMW 2025: DNV awards AiP to MARIC for ammonia-ready Kamsarmax bulk carrier

Classification society DNV on Wednesday (26 March) awarded an Approval in Principle (AiP) to Marine Design and Research Institute of China (MARIC) for their new wide beam ammonia-ready Kamsarmax bulk carrier, as part of Singapore Maritime Week (SMW 2025).

The vessel has a shallow draft for flexible port calls, as well as being WAPS (wind assisted propulsion system) ready.

Green ammonia is emerging as a strong candidate for the climate-neutral fuel shipping needs to meet its greenhouse gas reduction goals, especially when produced from renewably produced energy and inputs. In 2024, the first orders for non-gas carrier ammonia-fuelled vessels were placed, mainly in the bulk carrier segment, highlighting ammonia's emergence as a real option in the alternative fuel market.

To support the industry’s interest in the new fuel, DNV has awarded an AiP to Maric for a new ammonia-ready Kamsarmax bulk carrier design. With a length of 229 m and an increased beam of 38m, the design has been optimized for more cargo volume at same draft. 

The hull structure is reinforced, and space is reserved for an easier retrofit of both the ammonia tanks and system. With 4,500 CBM capacity tanks, the vessel can cover more than 15,000 nautical miles at design speed - fuelled on ammonia. 

Mr Zhu, Jianzhang, Vice President of MARIC, said: “We are proud to announce our strategic collaboration with DNV, to pioneer the design of a 91k DWT ammonia-fuelled bulk carrier. This partnership underscores our commitment to advancing green shipping technologies and accelerating the maritime industry’s transition to a low-carbon future.”

“By working together we can overcome the technical and operational challenges associated with ammonia as a marine fuel, deliver a cutting-edge solution that aligns with global decarbonization goals, and set a new benchmark for clean, efficient, and commercially viable bulk carriers.”

Øyvind Pettersen, Head of Technical Centre China, at DNV Maritime, said: "Awarding MARIC this AiP is another milestone in advancing ammonia as a marine fuel. However, realizing its potential demands both innovation and an unwavering focus on safety.”

“This is why we value working with MARIC and their commitment to building on the foundation of the industry's most advanced classification standards. DNV is very proud to collaborate on this AiP, which will strengthen confidence in new fuels, and further shipping’s journey toward a more sustainable tomorrow."

The first edition of DNV’s classification rules for ammonia-fuelled ships was published in 2021. Updates followed in 2022 and 2023, including the Gas Fuelled Ammonia class notation which gives owners the option to start building ships for future ammonia propulsion, by setting out the requirements for the ship’s fuel system, fuel bunkering connection and piping through to the fuel consumers. 

This year, a new DNV white paper, “Safe introduction of alternative fuels – Focus on ammonia and hydrogen as ship fuels”, provides shipowners with insights and tools to navigate the evolving regulatory landscape and implement these fuels.

An Approval in Principle (AiP) is an independent assessment of a concept within an agreed framework, confirming that the design is feasible, and no significant obstacles exist to prevent the concept from being realised.
