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.

Manabu Kawakado, Head of Marine Engineering Centre, Mitsubishi Shipbuilding Co., Ltd. said: “Our partnership with WinGD has made rapid progress in less than a year since we launched the cooperation. Concluding the initial AFSS design at this stage puts us in a strong position to offer a complete fuel system to ship operators as demand for carbon-free ammonia fuel grows over the coming years.”

Under the partnership, WinGD will develop X?DF?A engines at appropriate sizes for a range of vessel designs, providing the shipbuilder with the specifications for installing the engines and the requirements for all auxiliary fuel systems. Mitsubishi will design the vessels, set performance parameters for the engines and further develop its existing AFSS for use with WinGD’s ammonia engines.
