Alfa Laval has signed its first contract for its new ammonia fuel supply system, FCM Ammonia. The system will be installed onboard seven LPG/ammonia carriers being built in China Tianjin Southwest Maritime. The dual-cargo carriers will each feature a 6-cylinder version of WinGD’s X-DF-A engine, and are among the 30 vessels waiting for the first ammonia-capable engine deliveries from WinGD this June. The vessels are being built at CSSC Huangpu Wenchong shipyard, and installation will first commence aboard three 25,000 m3 capacity vessels, followed by four 41,000 m3 vessels.
Through research, product development, and strategic partnerships, we are building the solutions needed for a safe and efficient transition to low-carbon alternative fuels. Our deep experience with fuels like methanol and LPG has given us a head start with ammonia, and this first contract validates our commitment to driving decarbonization in shipping with reliable and innovative solutions.

Alfa Laval and WinGD have been collaborating on ammonia-powered shipping for some time. In December 2024, comprehensive testing of the full fuel supply system, fuel valve train, and vent treatment system commenced at WinGD’s Engine & Research Innovation Center in Winterthur, Switzerland. Ongoing testing will help validate the vent treatment system – also called the ammonia release mitigation system. December 2024 also saw the awarding AiP from the American Bureau of Shipping for an ammonia dual-fuel MR1 tanker designed by Alfa, WinGD and K Shipbuilding.
Collaborating with trusted partners such as Alfa Laval has been instrumental in bringing these new clean-fuel technologies to market, making ammonia-powered shipping a reality. This partnership, along with our joint R&D efforts, underscores our shared commitment to the clean energy transition to enable a sustainable future for shipping.
