October 2023- South Korean shipbuilding major HD Korea Shipbuilding & Marine Engineering will install ammonia dual-fuel engines in two 46,000-cubic-meter medium-sized LPG carriers that are being built for Belgian shipping company Exmar. The vessels, measuring 190 meters in length, 30.4 meters in width, and 18.8 meters in height, will be built at the Hyundai Mipo Dockyard in Ulsan and delivered sequentially to Exmar by May 2026. The duo is designed to transport both LPG and ammonia. KSOE celebrated this momentous achievement, proudly claiming the title of being the world's first shipyard to construct ammonia-powered vessels. Swiss marine power company WinGD confirmed that it would deliver its ammonia-fuelled X-DF-A engines to the two new buildings to be built for Exmar LPG BV, a joint venture of Exmar and Seapeak. The two 52-bore X52DF-A engines will be delivered in Q2 2025 and will be among the first of WinGD's ammonia-fuelled engines to enter service. The engines achieved the first-class authorization for ammonia two-stroke engines from LR in September 2023.  

September 2023- WinGD has ensured what it describes as the first-ever approval in principle (AIP) for two-stroke marine engines using ammonia fuel. Lloyd's Register awarded the AIP to the X-DF-A dual-fuel range. The AIP should give shipbuilders and owners the assurance they need to realize vessel designs using ammonia-fuelled main engines for the first time. The 52 cm bore X52 DF-A will be available for delivery from Q4 2024. It is suitable for a range of vessel types, including gas and bulk carriers.
