Simon Møkster, Wärtsilä tackle ammonia dual-fuel engine conversions
Wärtsilä Norway and Simon Møkster Shipping will collaborate on a feasibility study to utilise ammonia as the main fuel in dual-fuel engines in vessels that operate mainly on LNG
“Ammonia is regarded as one of the most interesting marine fuels for the future. By using a blend of ammonia and LNG, the emission of CO2 from the combustion process will be considerably reduced,” said Simon Møkster in a press statement.
Simon Møkster was one of the pioneers of LNG as a fuel in the offshore support vessel sector, adding VS-4403 Stril Pioneer to its fleet in 2003. Built to DNV class, the gas-powered 94.9-m offshore support vessel has Wärtsilä 6L32DF four-stroke, dual-fuel engines.
The aim of the project with Wärtsilä is to demonstrate that converting dual fuel-powered vessels is feasible, and that operating ammonia-LNG vessels can be done in a safe and efficient way.
“Møkster is excited to join forces with Wärtsilä for this project which may continue for several years to come,” said the Norwegian offshore support vessel owner.
The use of ammonia would underpin Simon Møkster Shipping’s ambition of cutting CO2 emissions from its fleet by 40% by 2030, and further working towards net-zero emissions in 2050. In the company’s 2020 Sustainability Report, Simon Møkster chief executive Anne Jorunn Møkster said, “By 2030, we shall achieve a 70% reduction in CO2 emissions per sailed distance. These ambitions are a continuation of the FuelRACE campaign, the company’s own fuel-saving initiative that started in 2014. In 2020 we made further leaps to reach our ambitions by reducing CO2 emissions by 13.9%, an improvement from a 10% reduction in 2019.”
