WinGD Powers First Ammonia Aframax Tankers


  • WinGD has landed a contract for two six-cylinder X-DF-A ammonia-fuelled engines from Singapore-based tanker company AET.
  • The engines will be the first ammonia dual-fuel units to be installed on Aframax tankers which are to be built at Dalian Shipbuilding Industry Co. Ltd.

WinGD has announced that its X‑DF‑A ammonia-fuelled engines will be installed in ‘the world’s first ammonia dual-fuel Aframax tankers’: two vessels that Dalian Shipbuilding Industry Co. (DSIC) is building for Singapore’s AET.

The Aframaxes will be fitted out with six-cylinder X62DF-A engines, the newest addition to WinGD’s clean-fuel engine portfolio.

First ammonia dual-fuel units

The order builds on previous cooperation between WinGD and AET on ammonia-fuelled shipping. In July 2023 the companies signed an agreement to collaborate on technology development and training for crew in partnership with ALAM (operated and managed by MISC’s Malaysian Maritime Academy) to prepare for ammonia-fuelled vessels entering service.

WinGD Director Sales Volkmar Galke said: ‘First adopters of ammonia fuel are signalling confidence in the viability of both the fuel and the technology to use it. We have been working closely with AET since last year to bring this order to reality. This order, backed by our string of Aprrovals in Principle (AiPs) for our safety concepts and fuel supply system design shows that WinGD is leading the way in bringing carbon-free ammonia power to the deep-sea fleet.’

WinGD has already secured orders for X52DF‑A engines for ammonia carriers as well as X72DF-A engines for bulk carriers. The 52 and 72-bore variants will be delivered in 2025 followed by the 62 bore and other engine sizes from 2026 onwards.
