WinGD has received another order for its X-DF-A ammonia-fuelled engines, which will power the world’s first ammonia dual-fuel Aframax tankers.
AET, a Singapore-based ship owner and operator, has ordered two vessels to be built at Dalian Shipbuilding Industry Co., Ltd (DSIC) with six-cylinder X62DF-A engines, a new addition to WinGD’s clean-fuel engine line.
The order builds on previous cooperation between WinGD and AET to enable clean-energy ship operations.
In July 2023, the firms inked an agreement to work on technological development and crew training in conjunction with ALAM (owned and managed by MISC’s Malaysian Maritime Academy Sdn. Bjd) to prepare for the introduction of ammonia-fueled vessels into 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 Approval in Principles (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 reportedly be supplied in 2025, followed by the 62-bore and other engine sizes in 2026, depending on market demand, to accommodate a wide variety of vessel types, from tiny tankers and car carriers to extremely large tankers.
The engines follow the diesel concept in both diesel and ammonia modes, with identical cylinder geometries and rating fields as WinGD’s well-known diesel-fueled X-Engine family.
In March, WinGD announced it would record the first installation of its new X‑S short‑stroke engine design following successful factory acceptance tests with engine builder Dalian Marine Diesel.
