The Ammonia Fuel Supply Systems (AFSS) is an innovative and reliable systems that enables the use of Ammonia as fuel and consequently a huge reduction in the vessels CO2 emissions. The use of Ammonia as marine fuel is likely to increase in the future and might be another step towards a greener society. Wärtsilä Gas Solutions AFSS systems are designed to be robust and reliable, even under the difficult maritime conditions.
For non-gas carriers (IGF-coded ships) the system can be configured with dedicated fuel storage tank(s) optimized for the trade of the vessel. The Ammonia fuel tank(s) is loaded through dedicated bunkering lines, or in case of a Ammonia/LPG carrier reloaded from the cargo tanks. From the fuel tank(s), the Ammonia is conditioned and prepared as fuel. A system consisting of pumps and heat exchanger is used to supply the engine with a stable and reliable fuel flow, at the correct pressure and temperature.
The AFSS systems are equipped with proven components, including the necessary purge gas treatment system. Due to the need for high cleanness of the fuel, proper filtering upstream is installed and embedded in the system.
