WinGD and Japanese shipbuilder and technology developer Mitsubishi Shipbuilding Co., Ltd. have completed the initial design of an ammonia fuel supply system (AFSS) for vessels powered by WinGD’s X‑DF‑A ammonia-fueled engines.

The AFSS design is the first result of a wide-ranging partnership announced last year that will develop solutions for ammonia engines and fuel systems that can be applied across a range of vessel designs. The project will now proceed to the detailed design phase, ensuring that ammonia capability is available to ocean going vessel operators ahead of regulatory requirements to reduce greenhouse gas emissions.

As well as the fuel supply system - including a fuel valve unit, fuel conditioning and all related piping – the concept includes several features to enable the safe use of ammonia as a marine fuel. These include an ammonia catching system as well as purging and venting arrangements.
