As was the case with the large-scale marine transportation of LNG (Liquified Natural Gas), the increasing expectations and social demand pressure on the land use of ammonia for electric power generation as an environmental measure are about to open the era of large-scale marine transportation of ammonia. The technologies for LNG carriers were applied to ships using LNG as fuel (hereafter LNG-fueled ships) and LNG fuel supply systems. It is expected that the technologies for ammonia carriers will be also applied to develop ships using ammonia as fuel (hereafter ammonia-fueled ships) and ammonia fuel supply systems. To widely promote the use of ammonia as marine fuel, it is necessary to set up ammonia related rules and training for crews, and ammonia-fueled ships and equipment should be developed as the extension of the same technology from LNG-fueled ships and equipment. In such way, it is desirable for manufacturers who provide ships and equipment and the potential operators of ammonia-fueled ships to develop in such a manner that common parts are inherited from LNG-fueled ships and equipment.
