'World-first' ammonia-fueled marine engine passes key validation test

Swiss marine power company WinGD has achieved a world-first milestone by successfully completing Type Approval Testing (TAT) and Factory Acceptance Testing (FAT) for its ammonia-fueled two-stroke marine engine, the X-DF-A 1.0. These tests were conducted at HD Hyundai Heavy Industries’ facility in South Korea on a 52-bore engine intended for installation on a 46,000m³ LPG/ammonia carrier operated by Belgian shipping firm EXMAR. The vessel is set to be among the first ammonia-fueled gas carriers to enter commercial service. The testing, witnessed by Lloyd’s Register and other classification societies, demonstrated the engine’s excellent performance, reliability, and safety, leading to 30 orders from customers across various vessel segments including gas carriers, bulk carriers, tankers, and container ships. Ammonia is highlighted as a promising marine fuel because it contains no carbon molecules, enabling up to a 90% reduction in greenhouse gas emissions if produced with renewable
