First Bunkering and Tests of Ammonia as Marine Fuel Completed in Singapore
In what may be a pivotal moment in the future of alternative marine fuels, the world’s first bunkering of ammonia and tests of adapted engines took place in Singapore aboard an offshore supply vessel retrofitted by Australia’s Fortescue Group. The testing is ongoing helping to develop the information on safety and management that might one day see ammonia become one of the leading marine fuels. The tests were carried out with the Fortescue Green Pioneer, a 3,100 dwt vessel built in 2010 in Indonesia. Fortescue Future Industries acquired the now 14-year-old supply ship MMA Leveque early in 2022 from Australia-based MMA Offshore. It was originally outfitted with four diesel-electric Cummins main engines. Fortescue began in 2022 testing the conversion of a four-stroke engine to run on ammonia in combination with diesel as its pilot fuel. The tests took place at the company’s facility in Perth, Australia, and in July 2023 the conversion work on the vessel began at Seatrium’s Benoi yard. Two of the vessel’s four engines were enabled to use ammonia in the process which included the installation of the gas fuel delivery system, safety systems, and the infrastructure to support the…
