Can green ammonia become the first financially viable ZNZ fuel?
Renewable fuels with zero or near-zero (ZNZ) emissions may seem a distant and expensive prospect for many ship operators. A recent report from WinGD and Envision shows how fast that could change, writes Fabio Cococcetta, Product Manager – Engines.
WinGD secures engine order for 12-vessel VLCC newbuild programme
WinGD has secured an order to supply main engines for a series of 12 Very Large Crude Carriers (VLCCs) being built at Hudong-Zhonghua Shipbuilding, China, for Dynacom, supporting the delivery of a new generation of efficient, reliable and regulation-ready tanker tonnage.
Since early in shipping’s decarbonisation process, LNG has been viewed by many as a pragmatic fuel: a lower-emissions option that avoids the cost and technology risks associated with green fuels until a better solution emerges. That transition may now last longer than expected.
In his presentation, ‘Ammonia 2-stroke engines, from concept to commercial application’, Dr. Topaloglou will explore the development journey behind the world's first commercially applied ammonia-fuelled two-stroke engines.
Drawing on operational experience from the first X-DF-A engines, he will discuss how continuous design refinement, safety-led engineering and practical testing have taken ammonia propulsion from concept to production-ready technology.
The session brings together experts from across the maritime industry to discuss the technical, regulatory and operational developments shaping ammonia as a marine fuel, from safety frameworks and lifecycle emissions to pioneering vessel applications and commercial deployment.

🎥How flexible is WinGD Ltd.’s X-DF-M/E engine when it comes to fuel choice?
In this WinGD Xpert episode, Leif Knipstrom, Senior Product Manager Diesel/Methanol explains the versatility of the X-DF-M/E engine platform.
From a dual-fuel setup, running on ethanol with diesel backup, to a tri-fuel configuration that allows operation on ethanol, methanol, or any blend of the two, the flexibility is built in.
This means operators can freely choose the most available or suitable fuel at any given time, without compromising performance.
🌱The result: greater fuel flexibility and operational efficiency, supporting the transition to low-carbon fuels.
In just under four weeks, the global maritime industry will gather in Hamburg for SMM 2026.
WinGD will be there to meet with customers, partners and industry stakeholders to discuss the technologies, fuels and services supporting shipping's transition.
In just under four weeks, the global maritime industry will gather in Hamburg for SMM 2026.
WinGD will be there to meet with customers, partners and industry stakeholders to discuss the technologies, fuels and services supporting shipping's transition.
From our LNG engine portfolio, including both X-DF and X-DF-HP technologies, to our growing range of ammonia, methanol and ethanol-capable engines, we'll be discussing the propulsion solutions enabling greater fuel flexibility across newbuild and existing fleets. Alongside this, we'll be showcasing our retrofit capabilities, digital technologies and Global Service offering, helping operators improve efficiency, reliability and long-term performance.
If you're attending SMM, we'd be pleased to meet and discuss how WinGD can support your operational and decarbonisation objectives.

🚢 ARLON enters service with WinGD Ltd. ammonia propulsion
Congratulations to Exmar on the delivery of ARLON, the second dual-fuel ammonia midsize gas carrier powered by a WinGD Ltd. X-DF-A engine.
Following the delivery of ANTWERPEN, ARLON represents another significant milestone for ammonia-fuelled shipping as the technology continues its transition from engine development to commercial operation.
Capable of carrying up to 46,000 m³ of ammonia or LPG, the vessel has been designed to operate on low-carbon ammonia fuel, supporting substantial greenhouse gas emissions reductions while transporting one of shipping's future fuels.
The next competitive advantage in marine propulsion may not be designed only in the engine factory. It may be built throughout the engine's entire operating life. This latest development from WinGD Ltd.highlights a trend that I believe will become increasingly important over the coming decade.…

The next competitive advantage in marine propulsion may not be designed only in the engine factory. It may be built throughout the engine's entire operating life. This latest development from WinGD Ltd. highlights a trend that I believe will become increasingly important over the coming decade.
Variable Compression Ratio (VCR) is certainly an efficiency technology, but its strategic significance goes further. Together with technologies such as iCER, digital optimisation and advanced engine controls, it reflects a broader transition from designing engines to continuously improving their operational performance.
That shift comes at an interesting moment. Following the discussions at IMO MEPC 84, the industry is moving towards greater emphasis on measured performance, lifecycle emissions and onboard verification. For LNG propulsion in particular, reducing methane slip is becoming more than an environmental objective. It is becoming an increasingly important competitive differentiator as operators seek to demonstrate real-world performance rather than rely solely on certified values.
This is why retrofit strategies deserve attention. A retrofit is not simply an upgrade. It extends the value of the installed base, enables compliance with evolving regulations, and creates new opportunities to improve efficiency throughout a vessel's lifecycle. Every engine already in service becomes a platform that can continue to evolve rather than a product whose value declines after delivery.
I believe this reflects a broader transformation taking place across industrial OEMs. The companies that create the greatest long-term value may not simply build the most efficient engines. They will be those that combine engineering excellence with lifecycle knowledge, digital capability and continuous customer support.
The future competitive advantage may belong not only to the best engine, but to the best-managed installed base.

As part of Gastech 2026, WinGD Ltd.'s Efstratios Fakiolas, Product Manager – LNG Engines, will be presenting during Alternative Propulsion: Session 1 in the Shipping & Marine Technical Conference.
In his presentation, Advanced marine engines for LNG utilisation: A transitional pathway to low-carbon shipping, Efstratios will explore how the latest advances in LNG engine technology are helping shipowners reduce emissions today while creating a practical pathway towards net-zero shipping. Topics will include reducing methane slip, improving efficiency through technologies such as iCER and Variable Compression Ratio (VCR), and the role of hybridisation and digital optimisation in supporting both newbuilds and retrofits.
The session brings together experts from across the industry to discuss practical solutions that can accelerate the transition to lower-carbon shipping, from wind-assisted propulsion and hybrid systems through to advanced LNG technologies and future energy concepts.
