Swiss engine maker WinGD has reached a major milestone in green shipping. The company has installed its first ammonia-fuelled two-stroke engine on a new gas carrier for EXMAR. This marks the first time an ammonia-powered gas carrier will enter commercial service.
The engine, known as the X52DF-A, was built by HD Hyundai Heavy Industries’ Engine & Machinery division. Also, it was installed on the first of four sister ships under construction at the Hyundai Mipo Dockyard in South Korea.
Initial results look promising. The engine’s performance in factory tests confirmed what WinGD had already seen in the lab: low emissions and fuel efficiency on par with diesel.
Τhe X-DF-A uses high-pressure ammonia injection. It also includes a small amount of pilot fuel, around five percent, to maintain stable combustion. This setup offers smooth power delivery and strong efficiency in both ammonia and diesel modes.
More improvements are already in progress. The second engine in this series is due for delivery later this year.
This project is the result of close collaboration. WinGD worked closely with shipowners and engine builders to ensure the engine is safe, reliable, and ready for real-world use. So far, around 30 of these engines have been ordered for a mix of gas carriers, bulkers, and container ships.
“With such convincing results, it is clear that ammonia fuel has a vital role to play in the decarbonisation of our industry,” said Sebastian Hensel,VP of Research and Development, WinGD.
Why ammonia? It contains no carbon and, when produced with renewable electricity, can cut greenhouse gas emissions by up to 90%. That makes it a powerful option for shipowners aiming to meet strict emissions targets.
With the first vessel nearing launch, WinGD is offering a real alternative for the next generation of clean shipping.
