Feasibility study of ammonia and LNG dual-fuel operations in Norway


Norway Wärtsilä and Simon Møkster Shipping of Norway have signed a collaboration agreement to conduct a feasibility study on using ammonia as the primary fuel in dual-fuel engines when LNG is the alternate fuel.

The goal is to show that adapting vessels for dual ammonia – LNG operation is feasible and can be done safely and efficiently. The contract was signed in October of 2021.

“We see this as a step towards meeting our targets for reducing greenhouse gas emissions, and our ambition is to cut our fleet’s CO2 emissions by 40 percent by 2030. By 2050 we expect to reach net-zero carbon emissions,” says Anne Jorunn Møkster, Owner and CEO Simon Møkster.

The testing will take place on the ‘Stril Pioneer,’ an offshore supply vessel (OSV) that is currently powered by Wärtsilä 32DF dual-fuel engines that use LNG as the primary fuel. Simon Mkster was a pioneer in using LNG as a marine fuel, adding the ‘Stril Pioneer’ to its fleet in 2003. CO2 emissions from the combustion process will be significantly decreased by employing a blend of ammonia and LNG.
