Swiss marine power company WinGD, Swedish marine technology leader Alfa Laval and the American Bureau of Shipping (ABS) will work with Korean shipbuilder K Shipbuilding (KSB) on the development of an ammonia-fuelled MR tanker design, under a memorandum of understanding signed in April. The design will feature a 6X52DF‑A engine from WinGD.
WinGD will work with KSB to deliver fuel gas system specifications suitable for the vessel application and the selected engine, while Alfa Laval will deliver the detailed documentation for the final fuel gas system design. The design will be reviewed by ABS, with the aim of issuing an approval in principle.
The X52DF‑A engine is the smallest bore size available in WinGD’s ammonia-fuelled X‑DF‑A series, and the first to be developed. It is expected to have wide application across bulk carriers, tankers and ammonia carriers, and has already been ordered for two ammonia carriers to be delivered in early 2026. The X52DF‑A is also the engine design on which four class societies to date, including ABS, have issued approvals in principle for the X‑DF‑A series, assuring shipowners that the engine can be deployed in operation safely.
JDPs and other cooperations have been a cornerstone of WinGD’s ammonia engine developments, with several industry partnerships focused on vessel designs and crew training – supporting both the deployment of ammonia-fuelled engines and the preparedness of the maritime industry to operate them safely.
