Methanol’s Case as a Marine Fuel
GREG DOLAN ferries powered by methanol ushering in a low-emission, fuel-ef? cient revolution in today’s marine ? eet. Partnering in the project are German shipyard Meyer
Werft, German shipbuilder Flensburger-
Schiffbau-Gesellschaft, and German methanol distributor HELM AG. Fund- ed by the German government, designs for the new methanol ships will be de- veloped over the next three years.
? In March 2015, the Swedish ferry operator Stena Line, relaunched the Ste- na Germanica featuring the world’s ? rst dual-fuel methanol propulsion system.
The 240-meter long, 1,500 passenger ro- pax ferry features four Wärtsilä engines, with one of the engines converted to methanol operation while in dry dock in
Poland’s Remontowa shipyard in Janu- ary 2015. Having been satis? ed with initial tests, the other three engines will now be converted one by one while the vessel is in service.
