WinGD on course for first ammonia engine deliveries in JuneWinGD on course for first ammonia engine deliveries in June
As successful testing of ammonia-fuelled engine technology continues at WinGD’s Engine Research and Innovation Centre (ERIC) in Switzerland the company is already building the first units.

The first ammonia-fuelled engines from WinGD will be for four LPG tankers and ten bulk carriers, with deliveries from June.
Key parameters in WinGD’s testing of its new X-DF-A ammonia-fuelled engine technology are in line with expectations and a company spokesperson tells Seatrade Maritime News that the first engines are currently being built. Final validation of the testing process at ERIC will enable the first units to be delivered from June.
Single-cylinder testing, designed to validate the ammonia combustion system under engine conditions, as well as optimising emissions and performance, follows earlier combustion and system validation on test rigs and class approvals of the safety concept, the engine firm said. Over the next few months, a multi-cylinder engine test at the company’s Global Research Centre in Shanghai will validate the full-scale engine, turbocharger configuration, and control system.
Sebastian Hensel, Vice President Research and Development, said: “The single-cylinder X-DF-A concept is running well, with combustion efficiency, emissions and pilot consumption within our range of expectations. This milestone is a testament to our uniquely rigorous approach to innovation and the fantastic work of our development team and partners.”
His colleague, Sotiris Topaloglou, Head of Testing and Validation added: “In previous tests, we verified that spray combustion chamber (SCC) results were transferable one-to-one to the results on our test engines, which is why we invest so much time on these early testing phases. As a result, we are in a strong position to make rapid progress through validation of our ammonia technology.”
WinGD’s ammonia development programme began in 2019. Three years later, the project was extended to testing of the company’s SCC technology, followed by investigations of key engine components on test rigs at the ERIC Future Fuels Lab.
The company has already landed contracts for close to 30 X-DF-A engines for ships including bulk carriers, container ships, tankers and LPG/ammonia carriers. The first units are now being built for four Exmar LPG gas carriers and ten CMB.Tech bulk carriers.
